PREVENTING CAVITIES
A GUIDE FOR PARENTS


A great deal of knowledge about 'cavities' has been gathered with scanning
electron microscopes and evidence-based bacteriologic studies.
Cavities are not created fair and equal.

In America, 30% of the children have 80% of the decay.
Quite a few factors are known to play a role in whether a patient has cavities
or not, those include:

1. decay history of patient
2. decay history of parents (esp. mother)
3. decay history of siblings
4. frequency of sugar (fermentable carbohydrates) in the diet
5. timing of sugar in diet related to brushing
6. brushing and flossing timing and frequency
7. fluoride exposure
8. saliva - flow and quality
9. tooth formation
10. type and number of Strep mutans bacteria the patient has

Cavities are caused by a common bacteria. Infants are usually born without
the bacteria known as Strep mutans, but are thought to be innoculated
through feeding practices. 99% of children inherit the type of Strep mutans
(Sm.) their mother is colonized with. If that happens to be a particularly
virulent type of Sm., the child is more likely to develop decay. The earlier the
child is infected with Sm., the greater the chance of developing decay.

PREVENTION - early. As soon as the teeth come in, start cleaning them- if
possible after each feeding. This will acclimatize your baby to having the
mouth/teeth touched. Some doctors even advocate wiping the gums before the teeth come in. After teeth erupt, try to not share spoons (straws, etc) so as to not spread Strep mutans. Try to clean the teeth after each feeding. Each time a child has a 'fermentable carbohydrate' (these include many healthy foods!), the bacteria form an acid. It takes normal saliva flow approximately 20 minutes to neutralize this acid, during this time the tooth is 'under attack' from the acid environment. As you can - considering health and weight gain, limit carbs in-between meals. Raw vegetables and cheese as snacks are much less decay-causing. Avoid introduction of very sweet foods to toddlers as long as possible.

Bottle and nursing habits can contribute to decay formation. Try to wean to a
cup between 12-18 months depending on your child. After this, it gets harder especially for Mom and Dad! Remember, a two year old's job seems to be
protesting. Sippy cups are very convenient to avoid spills, but please do not
give them as a “pacifier” all day - unless they are filled with water. Water
sipping is a tooth-healthy habit to encourage.

Pediatricians now advise limiting the total ounces of fruit juice per day.
Diluting with water will help it go further, again be wary of frequency.
Gatorades and sports drinks can promote cavities quickly (especially if used
frequently). Move to water as the sipping and exercise beverage between
meals as you can. Avoid sodas - even diet soda has a high acid content.

Advertising- This generation sees more ads for sweets and junk food on TV
than any previous generation. Be proactive and warn them that we don't
believe everything we see on TV. At the grocery store, take them through the
produce section and make a production about tastes, scents, colors, textures and vitamins and minerals we get from fruits and vegetables. Pick out a treat there so when you finish shopping and when you hit the candy isle, they already have their 'goodies'. The sticky candies which are marketed as 'fruit' are more likely to cause decay than candies which melt away from the teeth. Try not to pack them in lunches or give them as snacks where they can stay on the teeth even longer!

Brushing- Start with a small soft brush. It is very normal for children to chew
on them. When the bristles are bent, use a new brush. Have your child brush
first (if age appropriate) and then a parent brushes afterwards. It may be a
good idea for the parent to have a separate brush which will usually not be
bitten as much. As children grow, they normally get very independent about
brushing. The compromise we recommend is: they get to brush first and they
get to use a small dot of toothpaste - then parents 'touch up' . Remind them
that their eyes cannot see germs inside their own mouth, but parents can.
Parents should help with brushing until at least 8 years of age.

Flossing- Parents should floss when teeth touch together or if a youngster is
packing food. Children are not able to floss well alone until age 9 or 10.
Some parents find pre-threaded flossers much easier to use! There are
character flossers which can be fun, or Glide flossers which work well for very
tight contacts.

Fluoride – Different types of fluoride can be used to strengthen teeth. A small
amount daily has been found to be most beneficial. There are toothpastes,
rinses, gels, varnishes, and tablets- each patient has a different need so we
will discuss fluoride with you in the office. Swallowing too much fluoride can
cause fluorosis (discoloration) in the developing permanent teeth.

Sealants- This 'plastic-type' coating can significantly decrease decay in
grooved areas of the teeth. They are not very effective on smooth areas of the
teeth, unfortunately. We routinely place sealants on permanent molars with
deep grooves, but only occasionally place them on baby molar teeth.

Recaldent- This is a Calcium product derived from MILK proteins which is
currently in several chewing gums. Your child cannot use this product if they
have a milk allergy. Otherwise, the minerals in the gum become available in
the saliva and the tooth may use the calcium to repair small defects before the defects become a full cavity. Currently, it is available in TRIDENT White gum. It is also available in pastes and mints.

Xylitol- This hexose sugar is produced from birch trees and several fruits and
vegetables. Strep mutans cannot metabolize this sugar and it makes it harder for the bacteria to stick to the teeth. Xylitol is currently available in TRIDENT for kids gum. Please search the web for other products. Using too much xylitol may cause an unwanted laxative effect.

Other information for parents:

Sunscreen- Use it on their LIPS! The most common site of skin cancer in the
South is on the lower lip. When you put it on their bodies, don't forget the
lips.

Thumb and finger habits- These are very common for children. Most children
break themselves of the habit if not scolded too much. Between the ages of 4
and 6 we will check to see if intervention is necessary.

Grinding teeth- 50% of children grind their teeth at some time and child. If
your child is grinding, let us know so we can try to pinpoint causes and
solutions. Many children grind if they have sinus drainage or if they are
teething, especially when they are sleeping.

Tooth or mouth trauma- Thankfully, most trauma is related to bumps and
bruising while playing. Ice in the form of popscicles is helpful to slow and
stop minor bleeding and bruising. If the teeth are broken more than ¼ or if
you can visibly see the nerve (red in the middle of the tooth) your child needs
to be evaluated promptly. If at any time your child loses consciousness or is
not acting like himself, go to the emergency room for evaluation promptly.
