The straightening process for a crooked smile doesn't end when the braces come off. There's one more crucial phase to undergo to make sure we don't lose the progress you've achieved: wearing an orthodontic retainer.
Although often viewed as a nuisance, retainers are important because they prevent realigned teeth from reverting to their old positions. This is possible because the periodontal ligament, the gum attachment that allows us to move teeth in the first place, can contain “muscle memory” that naturally tries to draw teeth back to where they once were.
A retainer prevents this from happening: During wear the subtle pressure they exert keeps or “retains” the teeth in their new positions until they're firmly established, usually after several months. While most patients initially wear a retainer around the clock, this will gradually taper off until they're worn primarily during sleep hours.
While retainers come in many different styles and sizes, most fall into one of two categories: removable or non-removable (bonded). The first type, a custom-made appliance a patient can easily take in and out of the mouth, has its advantages. Removing it makes it easier to clean the teeth. They're also adaptable to reduced wear schedules for eating, brushing and flossing, or for special occasions.
But a removable retainer may be noticeable to others. Its removability can also lead to problems. Out of the mouth they're prone to be lost, resulting in additional replacement costs. And immature patients may be easily tempted to take them out too often—or not wear them at all.
A bonded retainer solves many of these potential problems. Because the retainer wire is securely bonded to the back of the teeth, it's not visible to others. And because it can't be removed except by an orthodontist, there's virtually no chance of losing it or haphazard wear.
On the other hand, bonded retainers can occasionally break, requiring repair or replacement. And flossing is more difficult than with a removable retainer, although a little training from a dental hygienist can make that easier.
The choice of retainer depends on the individual and their priorities. But whether removable or bonded, a retainer is absolutely essential for protecting your new, hard-earned smile.

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.

If you're intrigued by the strange and bizarre, here's one to pique your interest: geographic tongue. It's a rare condition that causes the appearance of red patches on the tongue surface, surrounded by grayish-white borders, and which look a lot like continents on a map (hence the name). But although it may look odd, geographic tongue won't harm your health.
The condition is also known as benign migratory glossitis, so named because it's not cancerous and the patches seem to move or “migrate” around the tongue surface. The most common causes are thought to be stress or hormonal disruptions in those predisposed to the condition. Many researchers believe zinc or vitamin B deficiencies in the body contribute to its occurrence. It also seems more prevalent among non-smokers and pregnant women, as well as occurring as a family trait.
The red patches are created by the temporary disappearance of some of the papillae, tiny bumps on the tongue's top surface. The patches can abruptly appear during a flareup and then disappear just as suddenly. But as “angry” as the patches may look, geographic tongue is not considered a health danger. It isn't normally painful, although people can experience stinging or numbing sensations emanating from the patches that can be mildly uncomfortable.
Because it's also rare, you're not likely to encounter it personally. But if you or a loved one does begin to notice red patches on the tongue, there are a few things you can do to lessen any accompanying irritation. For one, cut out foods like tomatoes, citrus fruits, eggplant, mint or highly spicy or acidic foods, all of which have been known to increase discomfort. You might also avoid astringents like alcohol or mouthwashes that likewise irritate the patches when they occur.
Although geographic tongue can't be cured, your dentist can help you manage symptoms when they arise with the help of prescribed anesthetic mouthwashes, antihistamines or steroid lozenges. These not only can help lower any discomfort or irritations, they may also lessen the duration of a flareup.
For the most part, geographic tongue usually causes more embarrassment than physical discomfort. But with a little help from your dentist, you can keep it to a minimum. Geographic tongue may be odd, but it's nothing to worry about.
