GENERAL TOPICS & FAQ
What Is A Pediatric Dentist?
The
pediatric dentist has an extra two to three years of specialized
training after dental school, and is dedicated to the oral
health of children from infancy through the teenage years. The
very young, pre-teens, and teenagers all need different
approaches in dealing with their behavior, guiding their dental
growth and development, and helping them avoid future dental
problems. The pediatric dentist is best qualified to meet these
needs.

Why
Are The Primary Teeth So Important?
It
is very important to maintain the health of the primary teeth.
Neglected cavities can and frequently do lead to problems which
affect developing permanent teeth. Primary teeth, or baby teeth
are important for (1) proper chewing and eating, (2) providing
space for the permanent teeth and guiding them into the correct
position, and (3) permitting normal development of the jaw bones
and muscles. Primary teeth also affect the development of speech
and add to an attractive appearance. While the front 4 teeth
last until 6-7 years of age, the back teeth (cuspids and molars)
aren’t replaced until age 10-13.

Eruption
Of Your Child’s Teeth
Children’s teeth begin forming before birth. As early as 4
months, the first primary (or baby) teeth to erupt through the
gums are the lower central incisors, followed closely by the
upper central incisors. Although all 20 primary teeth usually
appear by age 3, the pace and order of their eruption varies.
Permanent teeth begin appearing around age 6,
starting with the first molars and lower central incisors. This
process continues until approximately age 21.
Adults have 28 permanent teeth, or up to 32
including the third molars (or wisdom teeth).

Dental Emergencies
Toothache: Clean the area of the
affected tooth. Rinse the mouth thoroughly with warm water or
use dental floss to dislodge any food that may be impacted. If
the pain still exists, contact your child's dentist. Do
not place aspirin or heat on the gum or on the aching tooth. If
the face is swollen, apply cold compresses and contact your
dentist immediately.
Cut or Bitten
Tongue, Lip or Cheek:
Apply ice to injured areas to help control swelling. If there is
bleeding, apply firm but gentle pressure with a gauze or cloth.
If bleeding cannot be controlled by simple pressure, call a
doctor or visit the hospital emergency room.
Knocked Out
Permanent Tooth:
If possible, find the tooth. Handle it by the crown, not by the
root. You may rinse the tooth with water only. DO NOT clean with
soap, scrub or handle the tooth unnecessarily. Inspect the tooth
for fractures. If it is sound, try to reinsert it in the socket.
Have the patient hold the tooth in place by biting on a gauze.
If you cannot reinsert the tooth, transport the tooth in a cup
containing the patient’s saliva or milk. If the patient is old
enough, the tooth may also be carried in the patient’s mouth
(beside the cheek). The patient must see a dentist IMMEDIATELY!
Time is a critical factor in saving the tooth.
Knocked Out Baby Tooth:
Contact your pediatric dentist during business hours. This
is not usually an emergency, and in most cases, no treatment is
necessary.
Chipped or Fractured
Permanent Tooth: Contact your pediatric dentist
immediately. Quick action can save the tooth, prevent infection
and reduce the need for extensive dental treatment. Rinse the
mouth with water and apply cold compresses to reduce swelling.
If possible, locate and save any broken tooth fragments and
bring them with you to the dentist.
Chipped or Fractured
Baby Tooth: Contact your pediatric dentist.
Severe Blow to the Head: Take your
child to the nearest hospital emergency room immediately.
Possible Broken or Fractured Jaw:
Keep the jaw from moving and take your child to the nearest
hospital emergency room.

Dental Radiographs (X-Rays)
Radiographs (X-Rays) are a vital and
necessary part of your child’s dental diagnostic process.
Without them, certain dental conditions can and will be missed.

Radiographs detect much
more than cavities. For example, radiographs may be needed to
survey erupting teeth, diagnose bone diseases, evaluate the
results of an injury, or plan orthodontic treatment. Radiographs
allow dentists to diagnose and treat health conditions that
cannot be detected during a clinical examination. If dental
problems are found and treated early, dental care is more
comfortable for your child and more affordable for you.
The American Academy of Pediatric Dentistry
recommends radiographs and examinations every six months for
children with a high risk of tooth decay. On average, most
pediatric dentists request radiographs approximately once a
year. Approximately every 3 years, it is a good idea to obtain a
complete set of radiographs, either a panoramic and bitewings or
periapicals and bitewings.
Pediatric dentists are particularly careful
to minimize the exposure of their patients to radiation. With
contemporary safeguards, the amount of radiation received in a
dental X-ray examination is extremely small. The risk is
negligible. In fact, the dental radiographs represent a far
smaller risk than an undetected and untreated dental problem.
Lead body aprons and shields will protect your child. Today’s
equipment filters out unnecessary x-rays and restricts the x-ray
beam to the area of interest. High-speed film and proper
shielding assure that your child receives a minimal amount of
radiation exposure.

What’s
the Best Toothpaste for my Child?
Tooth brushing is one
of the most important tasks for good oral health. Many
toothpastes, an
d/or tooth polishes, however, can damage young smiles. They
contain harsh abrasives, which can wear away young tooth enamel.
When looking for a toothpaste for your child, make sure to pick
one that is recommended by the American Dental Association as
shown on the box and tube. These toothpastes have undergone
testing to insure they are safe to use.
Remember, children should spit out toothpaste
after brushing to avoid getting too much fluoride. If too much
fluoride is ingested, a condition known as fluorosis can occur.
If your child is too young or unable to spit out toothpaste,
consider providing them with a fluoride free toothpaste, using
no toothpaste, or using only a "pea size" amount of toothpaste.

Does Your
Child Grind His Teeth At Night? (Bruxism)
Parents are often concerned about the nocturnal grinding of
teeth (bruxism). Often, the first indication is the noise
created by the child grinding on their teeth during sleep. Or,
the parent may notice wear (teeth getting shorter) to the
dentition. One theory as to the cause involves a psychological
component. Stress due to a new environment, divorce, changes at
school; etc. can influence a child to grind their teeth. Another
theory relates to pressure in the inner ear at night. If there
are pressure changes (like in an airplane during take-off and
landing, when people are chewing gum, etc. to equalize pressure)
the child will grind by moving his jaw to relieve this pressure.
The majority of cases of
pediatric bruxism do not require any treatment. If excessive
wear of the teeth (attrition) is present, then a mouth guard
(night guard) may be indicated. The negatives to a mouth guard
are the possibility of choking if the appliance becomes
dislodged during sleep and it may interfere with growth of the
jaws. The positive is obvious by preventing wear to the primary
dentition.
The good news is most
children outgrow bruxism. The grinding decreases between the
ages 6-9 and children tend to stop grinding between ages 9-12.
If you suspect bruxism, discuss this with your pediatrician or
pediatric dentist.

Thumb
Sucking
Sucking
is a natural reflex and infants and young children may use
thumbs, fingers, pacifiers and other objects on which to suck.
It may make them feel secure and happy, or provide a sense of
security at difficult periods. Since thumb sucking is relaxing,
it may induce sleep.
Thumb sucking that
persists beyond the eruption of the permanent teeth can cause
problems with the proper growth of the mouth and tooth
alignment. How intensely a child sucks on fingers or thumbs will
determine whether or not dental problems may result. Children
who rest their thumbs passively in their mouths are less likely
to have difficulty than those who vigorously suck their thumbs.
Children should cease thumb sucking by the time their permanent
front teeth are ready to erupt. Usually, children stop between
the ages of two and four. Peer pressure causes many school-aged
children to stop.
Pacifiers are no
substitute for thumb sucking. They can affect the teeth
essentially the same way as sucking fingers and thumbs. However,
use of the pacifier can be controlled and modified more easily
than the thumb or finger habit. If you have concerns about thumb
sucking or use of a pacifier, consult your pediatric dentist.
A few suggestions to help
your child get through thumb sucking:
- Instead of scolding
children for thumb sucking, praise them when they are not.
- Children often suck
their thumbs when feeling insecure. Focus on correcting the
cause of anxiety, instead of the thumb sucking.
- Children who are
sucking for comfort will feel less of a need when their
parents provide comfort.
- Reward children when
they refrain from sucking during difficult periods, such as
when being separated from their parents.
- Your pediatric
dentist can encourage children to stop sucking and explain
what could happen if they continue.
- If these approaches
don’t work, remind the children of their habit by bandaging
the thumb or putting a sock on the hand at night. Your
pediatric dentist may recommend the use of a mouth
appliance.

What is Pulp Therapy?
The pulp of a tooth is the inner,
central core of the tooth. The pulp contains nerves, blood
vessels, connective tissue and reparative cells. The
purpose of pulp therapy in Pediatric Dentistry is to maintain
the vitality of the affected tooth (so the tooth is not lost).
Dental caries
(cavities) and traumatic injury are the main reasons for a tooth
to require pulp therapy. Pulp therapy is often referred to
as a "nerve treatment", "children's root canal", "pulpectomy" or
"pulpotomy". The two common forms of pulp therapy in
children's teeth are the pulpotomy and pulpectomy.
A pulpotomy
removes the diseased pulp tissue within the crown portion of the
tooth. Next, an agent is placed to prevent bacterial
growth and to calm the remaining nerve tissue. This is
followed by a final restoration (usually a stainless steel
crown).
A pulpectomy is
required when the entire pulp is involved (into the root
canal(s) of the tooth). During this treatment, the
diseased pulp tissue is completely removed from both the crown
and root. The canals are cleansed, disinfected and, in the
case of primary teeth, filled with a resorbable material.
Then, a final restoration is placed. A permanent tooth
would be filled with a non-resorbing material.

What
is the Best Time for Orthodontic Treatment?
Developing malocclusions, or bad bites, can be recognized as
early as 2-3 years of age. Often, early steps can be taken to
reduce the need for major orthodontic treatment at a later age.
Stage I – Early
Treatment: This period of treatment encompasses ages 2 to 6
years. At this young age, we are concerned with underdeveloped
dental arches, the premature loss of primary teeth, and harmful
habits such as finger or thumb sucking. Treatment initiated in
this stage of development is often very successful and many
times, though not always, can eliminate the need for future
orthodontic/orthopedic treatment.
Stage II – Mixed
Dentition: This period covers the ages of 6 to 12 years, with
the eruption of the permanent incisor (front) teeth and 6 year
molars. Treatment concerns deal with jaw malrelationships and
dental realignment problems. This is an excellent stage to start
treatment, when indicated, as your child’s hard and soft tissues
are usually very responsive to orthodontic or orthopedic forces.
Stage III – Adolescent Dentition:
This stage deals with the permanent teeth and the development of
the final bite relationship.

EARLY INFANT ORAL CARE
Your
Child’s First Dental Visit
According to the American Academy of Pediatric Dentistry (AAPD),
your child should visit the dentist by his/her 1st
birthday. You can make the first visit to the dentist enjoyable
and positive. Your child should be informed of the visit and
told that the dentist and their staff will explain all
procedures and answer any questions. The less to-do concerning
the visit, the better.
It is best if you refrain
from using words around your child that might cause unnecessary
fear, such as needle, pull, drill or hurt. Pediatric dental
offices make a practice of using words that convey the same
message, but are pleasant and non-frightening to the child.

When
Will My Baby Start Getting Teeth?
Teething, the process
of baby (primary) teeth coming through the gums into the mouth,
is variable among individual babies. Some babies get their teeth
early and some get them late. In general, the first baby teeth
to appear are usually the lower front (anterior) teeth and they
usually begin erupting between the age of 6-8 months. See "Eruption
of Your Child’s Teeth" for more
details.
[Back

Baby
Bottle Tooth Decay (Early Childhood Caries)
One serious form of decay
among young children is baby bottle tooth decay. This condition
is caused by frequent and long exposures of an infant’s teeth to
liquids that contain sugar. Among these liquids are milk
(including breast milk), formula, fruit juice and other
sweetened drinks.
Putting a baby to bed for a nap or at night with a bottle other
than water can cause serious and rapid tooth decay. Sweet liquid
pools around the child’s teeth giving plaque bacteria an
opportunity to produce acids that attack tooth enamel. If you
must give the baby a bottle as a comforter at bedtime, it should
contain only water. If your child won't fall asleep
without the bottle and its usual beverage, gradually dilute the
bottle's contents with water over a period of two to three
weeks.
After each feeding, wipe
the baby’s gums and teeth with a damp washcloth or gauze pad to
remove plaque. The easiest way to do this is to sit down, place
the child’s head in your lap or lay the child on a dressing
table or the floor. Whatever position you use, be sure you can
see into the child’s mouth easily.

PREVENTION
Care of Your Child’s Teeth
Begin daily brushing as
soon as the child’s first tooth erupts. A pea size amount of
fluoride toothpaste can be used after the child is old enough
not to swallow it. By age 4 or 5, children should be able to
brush their own teeth twice a day with supervision until about
age seven to make sure they are doing a thorough job. However,
each child is different. Your dentist can help you determine
whether the child has the skill level to brush properly.
Proper brushing removes
plaque from the inner, outer and chewing surfaces. When teaching
children to brush, place toothbrush at a 45 degree angle; start
along gum line with a soft bristle brush in a gentle circular
motion. Brush the outer surfaces of each tooth, upper and lower.
Repeat the same method on the inside surfaces and chewing
surfaces of all the teeth. Finish by brushing the tongue to help
freshen breath and remove bacteria.
Flossing removes plaque between the teeth, where a toothbrush
can’t reach. Flossing should begin when any two teeth touch. You
should floss the child’s teeth until he or she can do it alone.
Use about 18 inches of floss, winding most of it around the
middle fingers of both hands. Hold the floss lightly between the
thumbs and forefingers. Use a gentle, back-and-forth motion to
guide the floss between the teeth. Curve the floss into a
C-shape and slide it into the space between the gum and tooth
until you feel resistance. Gently scrape the floss against the
side of the tooth. Repeat this procedure on each tooth. Don’t
forget the backs of the last four teeth.

Good Diet = Healthy Teeth
Healthy
eating habits lead to healthy teeth. Like the rest of the body,
the teeth, bones and the soft tissues of the mouth need a
well-balanced diet. Children should eat a variety of foods from
the five major food groups. Most snacks that children eat can
lead to cavity formation. The more frequently a child snacks,
the greater the chance for tooth decay. How long food remains in
the mouth also plays a role. For example, hard candy and breath
mints stay in the mouth a long time, which cause longer acid
attacks on tooth enamel. If your child must snack, choose
nutritious foods such as vegetables, low-fat yogurt, and low-fat
cheese, which are healthier and better for children’s teeth.
[Back
to Top]
How Do I
Prevent Cavities?
Good oral hygiene
removes bacteria and the left over food particles that combine
to create cavities. For infants, use a wet gauze or clean
washcloth to wipe the plaque from teeth and gums. Avoid putting
your child to bed with a bottle filled with anything other than
water. See "Baby
Bottle Tooth Decay" for more
information.
For older children,
brush their teeth at least twice a day. Also, watch the
number of snacks containing sugar that you give your children.
The American Academy of Pediatric Dentistry
recommends visits every six months to the pediatric dentist,
beginning at your child’s first birthday. Routine visits will
start your child on a lifetime of good dental health.
Your pediatric dentist may also recommend
protective sealants or home fluoride treatments for your child.
Sealants can be applied to your child’s molars to prevent decay
on hard to clean surfaces.
[Back
to Top]
Seal Out Decay
A sealant is a clear or
shaded plastic material that is applied to the chewing surfaces
(grooves) of the back teeth (premolars and molars), where four
out of five cavities in children are found. This sealant acts as
a barrier to food, plaque and acid, thus protecting the
decay-prone areas of the teeth.

Fluoride
Fluoride is an element,
which has been shown to be beneficial to teeth. However, too
little or too much fluoride can be detrimental to the teeth.
Little or no fluoride will not strengthen the teeth to help them
resist cavities. Excessive fluoride ingestion by preschool-aged
children can lead to dental fluorosis, which is a chalky white
to even brown discoloration of the permanent teeth. Many
children often get more fluoride than their parents realize.
Being aware of a child’s potential sources of fluoride can help
parents prevent the possibility of dental fluorosis.
Some
of these sources are:
- Too much fluoridated
toothpaste at an early age.
- The inappropriate use
of fluoride supplements.
- Hidden sources of
fluoride in the child’s diet.
Two and three year olds
may not be able to expectorate (spit out) fluoride-containing
toothpaste when brushing. As a result, these youngsters may
ingest an excessive amount of fluoride during tooth brushing.
Toothpaste ingestion during this critical period of permanent
tooth development is the greatest risk factor in the development
of fluorosis.
Excessive and
inappropriate intake of fluoride supplements may also contribute
to fluorosis. Fluoride drops and tablets, as well as fluoride
fortified vitamins should not be given to infants younger than
six months of age. After that time, fluoride supplements should
only be given to children after all of the sources of ingested
fluoride have been accounted for and upon the recommendation of
your pediatrician or pediatric dentist.
Certain foods contain high levels of fluoride, especially
powdered concentrate infant formula, soy-based infant formula,
infant dry cereals, creamed spinach, and infant chicken
products. Please read the label or contact the manufacturer.
Some beverages also contain high levels of fluoride, especially
decaffeinated teas, white grape juices, and juice drinks
manufactured in fluoridated cities.
Parents can take the
following steps to decrease the risk of fluorosis in their
children’s teeth:
-
Use baby tooth cleanser on the toothbrush
of the very young child.
- Place only a pea
sized drop of children’s toothpaste on the brush when
brushing.
- Account for all of
the sources of ingested fluoride before requesting fluoride
supplements from your child’s physician or pediatric
dentist.
- Avoid giving any
fluoride-containing supplements to infants until they are at
least 6 months old.
- Obtain fluoride level
test results for your drinking water before giving fluoride
supplements to your child (check with local water
utilities).

Mouth Guards
When a child begins to
participate in recreational activities and organized sports,
injuries can occur. A properly fitted mouth guard, or mouth
protector, is an important piece of athletic gear that can help
protect your child’s smile, and should be used during any
activity that could result in a blow to the face or mouth.
Mouth guards help prevent broken teeth, and injuries to the
lips, tongue, face or jaw. A properly fitted mouth guard will
stay in place while your child is wearing it, making it easy for
them to talk and breathe.
Ask your pediatric dentist about custom
and store-bought mouth protectors.
[Back
to Top]
Xylitol -
Reducing Cavities
The American Academy of Pediatric Dentistry
(AAPD) recognizes the benefits of xylitol on the oral health of
infants, children, adolescents, and persons with special health
care needs.
The use of XYLITOL GUM by
mothers (2-3 times per day) starting 3 months after delivery and
until the child was 2 years old, has proven to reduce cavities
up to 70% by the time the child was 5 years old.
Studies using xylitol as either a
sugar substitute or a small dietary addition have demonstrated a
dramatic reduction in new tooth decay, along with some reversal
of existing dental caries. Xylitol provides additional
protection that enhances all existing prevention methods. This
xylitol effect is long-lasting and possibly permanent. Low decay
rates persist even years after the trials have been completed.
Xylitol is widely
distributed throughout nature in small amounts. Some of the best
sources are fruits, berries, mushrooms, lettuce, hardwoods, and
corn cobs. One cup of raspberries contains less than one gram of
xylitol.
Studies suggest xylitol intake that consistently produces
positive results ranged from 4-20 grams per day, divided into
3-7 consumption periods. Higher results did not result in
greater reduction and may lead to diminishing results.
Similarly, consumption frequency of less than 3 times per day
showed no effect.
To find gum or other products containing
xylitol, try visiting your local health food store or search the
Internet to find products containing 100% xylitol.

ADOLESCENT DENTISTRY
Tongue Piercing – Is it Really Cool?
You might not be surprised
anymore to see people with pierced tongues, lips or cheeks, but
you might be surprised to know just how dangerous these
piercings can be.
There are many risks
involved with oral piercings, including chipped or cracked
teeth, blood clots, blood poisoning, heart infections, brain
abscess, nerve disorders (trigeminal neuralgia), receding gums
or scar tissue. Your mouth contains millions of bacteria, and
infection is a common complication of oral piercing. Your tongue
could swell large enough to close off your airway!
Common symptoms after piercing include pain, swelling,
infection, an increased flow of saliva and injuries to gum
tissue. Difficult-to-control bleeding or nerve damage can result
if a blood vessel or nerve bundle is in the path of the needle.
So follow the advice of
the American Dental Association and give your mouth a break –
skip the mouth jewelry.

Tobacco – Bad News in
Any Form
Tobacco in any form can jeopardize your child’s health and cause
incurable damage. Teach your child about the dangers of tobacco.
Smokeless tobacco, also
called spit, chew or snuff, is often used by teens who believe
that it is a safe alternative to smoking cigarettes. This is an
unfortunate misconception. Studies show that spit tobacco may be
more addictive than smoking cigarettes and may be more difficult
to quit. Teens who use it may be interested to know that one can
of snuff per day delivers as much nicotine as 60 cigarettes. In
as little as three to four months, smokeless tobacco use can
cause periodontal disease and produce pre-cancerous lesions
called leukoplakias.
If
your child is a tobacco user you should watch for the following
that could be early signs of oral cancer:
- A sore that won’t
heal.
- White or red leathery
patches on the lips, and on or under the tongue.
- Pain, tenderness or
numbness anywhere in the mouth or lips.
- Difficulty chewing,
swallowing, speaking or moving the jaw or tongue; or a
change in the way the teeth fit together.
Because the early signs of oral cancer usually are not painful,
people often ignore them. If it’s not caught in the early
stages, oral cancer can require extensive, sometimes
disfiguring, surgery. Even worse, it can kill.
Help your child avoid
tobacco in any form. By doing so, they will avoid bringing
cancer-causing chemicals in direct contact with their tongue,
gums and cheek.
