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.

The amount of sugar your child consumes has a huge bearing on their tooth decay risk: The more they take in, the higher it is for this destructive disease. That's why you should moderate their intake of the usual suspects: sodas, candies and other sugar-laden foods. But you should also put the brakes on something considered wholesome and nutritious: fruit juices. And that includes all natural juice with no sugar added.
Sugar in any form is a prime food source for decay-causing bacteria. As bacteria consume leftover sugar in the mouth, they produce acid as a byproduct. With an ample source of sugar, they also multiply—and this in turn increases their acid production. Acid at these high levels can soften and erode tooth enamel, which leads to tooth decay and cavities.
Limiting or even excluding sugar-added foods and snacks can help minimize your children's risk for tooth decay. For designated snack times, substitute items like carrot sticks or even popcorn with a dash of spice rather than sweet snacks and candies. If you do allow occasional sweet foods, limit those to mealtimes when saliva, which neutralizes acid, is most active in the mouth.
As you manage sugary items your children may eat or drink, the American Academy of Pediatrics also advises you to moderate their consumption of fruit juices, including all-natural brands with no added sugar. Their recommended limits on daily juice drinking depend on a child's age and overall health:
- Infants (less than one year) or any children with abnormal weight gain: no juice at all;
- Toddlers (ages 1-3): 4 ounces or less per day;
- Younger children (4-6): 6 ounces or less per day; and
- Older children (7-18): 8 ounces (1 cup) or less per day.
As for the rest of your children's daily hydration needs, the most dental-friendly liquid for any of us is plain water. For older school-age children, low- or non-fat milk is also a sound choice.
Preventing tooth decay in your children is a continuous task that requires all of us, parents and dental providers, to do our part. Besides daily hygiene (brushing and flossing) and regular dental visits, keeping sugar at bay—including with juices—is an important part of that effort.
It's not an exaggeration to say the modern root canal treatment has saved millions of teeth over the last century. Without this procedure, there's not a lot we can do to stop advanced tooth decay from infecting and destroying a tooth.
What's more, a root canal treatment could extend the life of a tooth for decades. Notice we said could—although most root canals do have satisfactory outcomes, there's still a chance a tooth may become re-infected. Here are 3 possible causes for an unsuccessful root canal treatment, and what you can do to lessen their impact.
The severity of the infection. Tooth decay usually begins at the enamel layer, softened by the acid produced by bacteria. Untreated, the infection can then spread through the next tooth layer of dentin until finally infecting the innermost pulp. From there the infection can move through the root canals to the bone, dramatically increasing the danger to the tooth. Root canal treatments have a higher chance of success the earlier they're performed in the disease progression, so see your dentist at the first sign of pain or other tooth abnormality.
The root canal network. An effective root canal procedure eliminates all dead or diseased tissue in both the pulp chamber and the root canals (these are then filled to prevent future infection). But this may prove difficult with teeth that have intricate root canal networks because of a higher risk of overlooking some of the canals. It may be best in such cases for an endodontist, a specialist in treating interior tooth issues, to perform the procedure using their advanced techniques and microscopic equipment.
The age of the tooth. Root canal treatment can weaken a tooth's structural integrity, especially with older teeth. This can make them more susceptible to fracture and a higher chance of infection. We can avoid this outcome by placing crowns on root-canaled teeth: The crown provides structural strength to the tooth and can add further protection against infection. Older teeth may also benefit from the placement of a small support post within it to further add stability before applying the crown.
