KeepYourChildsFluorideIntakeataSafebutEffectiveLevel

Fluoride is an important part of your child's dental development. But if children take in too much of this important mineral, they could experience enamel fluorosis, a condition in which teeth become discolored with dark streaking or mottling.

That's why it's important to keep fluoride levels within safe bounds, especially for children under the age of 9. To do that, here's a look at the most common sources for fluoride your child may take in and how you can moderate them.

Toothpaste. Fluoridated toothpaste is an effective way for your child to receive the benefits of fluoride. But to make sure they're not getting too much, apply only a smear of toothpaste to the brush for infants. When they get a little older you can increase that to a pea-sized amount on the end of the brush. You should also train your child not to swallow toothpaste.

Drinking water. Most water systems add tiny amounts of fluoride to drinking water. To find out how much your water provider adds visit “My Water's Fluoride” (//nccd.cdc.gov/doh_mwf/Default/Default.aspx) online. If it's more than the government's recommendation of 0.70 parts of fluoride per million parts of water, you may want ask your dentist if you should limit your child's consumption of fluoridated drinking water.

Infant formula. Many parents choose bottle-feeding their baby with infant formula rather than breastfeed. If you use the powdered form and mix it with tap water that's fluoridated, your baby could be ingesting more of the mineral. If breastfeeding isn't an option, try using the premixed formula, which normally contains lower levels of fluoride. If you use powdered formula, mix it with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”

It might seem like the better strategy for preventing fluorosis is to avoid fluoride altogether. But that can increase the risk of tooth decay, a far more destructive outcome for your child's teeth than the appearance problems caused by fluorosis. The better way is to consult with your dentist on keeping your child's intake within recognized limits to safely receive fluoride's benefits of stronger, healthier teeth.

2KindsofOrthodonticRetainersThatCanProtectYourNewSmile

While retainers are often viewed as a nuisance, they’re crucial to protect the gains made with bite correction. Without them, all of the progress achieved through braces or clear aligners could be lost.

Here’s why: The same elastic gum tissue called the periodontal ligament that holds teeth in place also allows them to move incrementally in response to changes in the mouth. That’s why we can move teeth with braces or aligners, which put pressure on the teeth toward a desired direction of movement while the periodontal ligament does the rest.

But the mechanics can also work in reverse: With pressure relieved when the braces are removed, the teeth could revert to their original positions through a kind of “muscle memory.” The light pressure provided by a retainer is enough to keep or “retain” teeth in their new positions.

The best known retainer is a removable appliance. Initially, a patient wears it continuously and only takes it out during oral hygiene. Wear duration may later be reduced to night time only and eventually not at all, depending on a patient’s individual needs.

While effective, removable retainers do have some downsides. Like braces, they’re visible to others. And because they’re removable, they’re frequently misplaced or lost, leading to the added expense of a new one.

An alternative is a bonded retainer, a thin piece of wire attached to the back of the newly moved teeth to keep them in place. Because it’s behind the teeth it’s not visible—and there’s no misplacing it because only a dentist can take it out.

A bonded retainer is a good option, especially if a patient is immature and not as diligent about wearing or keeping up with their appliance. But it can make flossing difficult to perform, and if they’re removed or broken prematurely, the teeth could revert to their former positions.

If you decide to go with a bonded retainer, be sure you get some tips from your dental hygienist on how to floss with it. And if you decide later to have it removed early, be sure to replace it with a removable retainer. Either of these two options can help you keep your new and improved smile.

If you would like more information on bonded retainers, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Bonded Retainers.”

TheKindofToothPainYouHaveMayIdentifytheTrueProblem

Pain can tell you things. Not verbally, of course, as in, “Hey, your appendix is inflamed!” But the quality of your pain—dull or sharp, constant or intermittent, acute or general—can point the way to the actual problem.

That's especially true of tooth pain, which could signal any number of dental problems. Looking at its characteristics, though, can narrow the search. Here are a few examples.

Sharp, momentary pain. This could be an indication of a number of possible dental problems. If it occurs for a few seconds after eating or drinking something hot or cold, it might signal a small area of tooth decay, a loose filling or early signs of gum recession. The latter could be a symptom of periodontal (gum) disease, so you should seek diagnosis and treatment as soon as possible.

Sharp pain when biting. Like tooth sensitivity, this could be a sign of decay or a loose filling, or it could indicate a fractured (cracked) tooth. If it's the latter, you may need an endodontist, a specialist in interior tooth problems, if you want the best chance for saving the tooth.

Dull ache in upper teeth. This might not be a dental problem at all, but radiating pain from an infection of the sinus just above the upper posterior teeth. The infection could also have begun with one of the molar teeth and advanced into the sinus. You'll need to see your dentist for any teeth or gums involved and possibly a physician to address any potential sinus infection.

Constant throbbing pain. That horrible toothache that won't stop could be the nerves in the tooth's interior under attack from decay. The primary means for saving a tooth with deep decay is a root canal treatment to clean out diseased tissue and replace it with a filling or a crown. You should see a dentist even if the pain suddenly subsides—this may only mean the nerves have died, but the infection is still active.

These are just a few of the problems, including true dental emergencies, that oral pain can signal. For any instance of pain in your mouth, see your dentist as soon as possible.
