Your gums don't just attractively frame your teeth—they protect them as well. If they shrink back (recede) from their normal covering, portions of the teeth could become exposed to bacteria and other hazards.
Unlike the visible crown, which is protected by enamel, the tooth root depends largely on the gums as a shield against bacteria and other hazards. When the gums recede, it exposes the roots and makes them more susceptible to disease or trauma. It may also cause sensitivity to hot and cold foods as the now exposed dentin gets the full brunt of temperature and pressure sensations once muffled by the gums.
There are actually a number of causes for gum recession. In rare cases, a tooth may not have erupted normally within its bony housing, which inhibits the gums from covering it fully. Thinner gum tissues, passed down genetically, are also more susceptible to recession. And a person can even damage their gums and cause them to recede if they brush too aggressively.
The most common cause, though, is advanced periodontal (gum) disease. This bacterial infection arises from dental plaque, a thin biofilm that accumulates on tooth surfaces, usually because of poor hygiene practices. As the infection and resulting inflammation in the gums worsens, they lose their attachment to teeth resulting in a number of harmful outcomes that include recession.
The first step then in treating gum recession is to treat the underlying problem as much as possible. In the case of gum disease, effective treatment could stop mild to moderate recession and sometimes reverse it. For more extensive recession, a patient may need gum grafting surgery to help regenerate lost gum tissue.
You can help prevent gum disease, and thus lower your risk for recession, with daily brushing and flossing to remove bacterial plaque. Likewise, see your dentist at least twice a year for dental cleanings to remove any residual plaque and tartar (hardened plaque).
You should also visit your dentist promptly if you notice swollen or bleeding gums, or more of your teeth surfaces showing. The earlier your dentist diagnoses and begins treatment for gum recession, the better your chances for a healthy and more attractive outcome.

You could have an unattractive smile because of a chipped tooth or one slightly out of alignment. Or, it could be both of the above, plus some heavy staining to boot. Correcting each flaw individually might require a combination of different methods like orthodontics or porcelain crowns, which can take an extended period of time to complete.
But you may be able to correct numerous smile flaws with just one method—and in no more than a couple of treatment visits. It's called direct veneers.
Unlike regular veneers, direct veneers don't require a dental technician to craft a thin porcelain shell to bond over teeth. Rather, a dentist applies a tooth-colored material called composite resin to the problem teeth and "sculpts" an entirely new look that can correct multiple dental flaws at one time.
The dentist usually begins the process by creating a model ("wax-up") of proposed changes based on physical impressions of the jaw and teeth. Both dentist and patient can study the model and modify it if necessary, when finalizing the treatment plan.
At a subsequent appointment, the dentist prepares the tooth surface for bonding by removing a thin layer of tooth enamel, then shapes the teeth to better accommodate the composite resin. This tooth prep is similar to that done with traditional veneers, so it's permanent—the teeth will require some form of restoration from then on.
After applying an etchant and a bonding agent, the dentist applies the composite resin in small amounts, hardening each layer with a special light before applying the next one. With each subsequent layer, the dentist sculps the composite material to eventually resemble the wax-up model.
After completing the composite application, the dentist then uses hand tools and a dental drill to complete shaping, as well as an abrasive strip between teeth to aid future flossing. After just a few hours, the transformation is complete.
Direct veneers are durable, but not to the same extent as regular veneers or other cosmetic enhancements. They can also pick up stains over time, and may require re-treatment at some point. Still, direct veneers are a cost-effective way to improve the appearance of teeth with multiple flaws that could radically change your smile for the better.
For some, the excitement over their braces coming off gets dampened a bit with the prospect of now having to wear a retainer. But it has to be—newly realigned teeth have a tendency to revert to their previous positions out of a kind of “muscle memory.” A retainer prevents that from happening.
But as essential as it is, the standard retainer is almost as noticeable as braces, a major reason why many patients are less than enthusiastic about wearing them. And, because it's common for them to become lost when out of the mouth, replacing one becomes an added expense.
But there's another option—the bonded retainer. This retainer consists of a metal wire bonded to the back of the teeth to prevent them from moving. Because it's fixed in place, only a dentist can remove it.
The bonded retainer addresses the previous two issues associated with a removable retainer. Because it's behind the teeth rather than in front, it's out of sight to others. And, because it's fixed in place, there's no danger of losing it.
But unlike its removable cousin, which can be taken out for oral hygiene, the bonded retainer can make flossing more difficult. And, by nature, a bonded retainer must be worn all the time; a removable retainer allows for a more flexible schedule later in the treatment of a few hours a day.
So, which retainer option is best for you or another family member? A bonded retainer may be more attractive for appearance's sake, if it must be worn indefinitely, or if there's a high probability of the teeth moving out of alignment. And, it might be the right choice where there's a concern about a patient's ability to keep up with a removable retainer.
If you do decide to go with a bonded retainer, ask your dental hygienist for training on using floss with the fixed appliance—this can help improve oral hygiene. Whatever you choose, bonded or removable, your retainer will help you keep that new, beautiful, straightened smile.
