Most dental problems are caused by tooth decay or periodontal (gum) disease, easily preventable with dedicated daily hygiene and regular dental care. But there are a few other rare conditions to be on alert for that could pose just as serious a threat to your dental health.
One of these is a phenomenon called root resorption. Put simply, certain cells arise within a tooth root that eat away and dissolve (resorb) tooth structure. Left unchecked, it could eventually lead to the tooth's demise.
Although its exact cause remains elusive, we suspect root resorption is associated with trauma to the gum ligaments earlier in life, perhaps from an injury or too much force applied during orthodontics. Other possible contributing factors include teeth-grinding habits or internal tooth bleaching procedures.
Root resorption in adults isn't that common, so your chances of experiencing it are low. But it is still possible, so you should be on the lookout for potential signs: Early on, it may appear as faint pink spots on teeth where the enamel has filled with the destructive cells eating away at the tooth. In time, these spots can increase to form cavities.
More than likely, though, your dentist may detect the problem during a dental exam. That's why regular dental cleanings and checkups are essential—a routine exam is a prime opportunity to uncover conditions like root resorption that silently undermine your teeth.
If found early, we can often treat root resorption effectively. We can often expose a small affected area with minor gum surgery, remove the harmful cells and fill any cavities with a tooth-colored filling. In some cases, we may recommend orthodontics beforehand to encourage a buildup of bone around the root by moving the affected tooth outward from the jawbone. If the resorption has affected the tooth pulp, you may also need a root canal treatment.
There is also the possibility with advanced resorption that the best course of action is to remove the tooth and replace it with a dental implant. So, keep up your regular dental visits—early detection and intervention can stop this destructive dental condition from destroying your tooth.

The timing around losing a tooth may not always sync with your financial ability. It's not unusual for people to postpone getting a dental implant—by far the best option for replacing a missing tooth—because of its expense.
So, if you have to postpone dental implants until you can afford them, what do you do in the meantime to keep your smile intact? One affordable option is a temporary restoration known as a flexible removable partial denture (RPD).
Composed of a kind of nylon developed in the 1950s, flexible RPDs are made by first heating the nylon and injecting its softened form into a custom mold. This creates a gum-colored denture base to which prosthetic (false) teeth are affixed at the exact locations for missing teeth.
Differing from a permanent RPD made with rigid acrylic plastic, a nylon-based RPD is flexible and lightweight, making them comfortable to wear. They're kept in place with small nylon extensions that fit into the natural concave spaces of teeth. And, with a bit of custom crafting, they can look quite realistic.
RPDs are helpful in another way, especially if you're waiting for an implant down the road: They help preserve the missing tooth space. Without a prosthetic tooth occupying that space, neighboring teeth can drift in. You might then need orthodontic treatment to move errant teeth to where they should be before obtaining a permanent restoration.
Flexible RPDs may not be as durable as acrylic RPDs, and can be difficult to repair or reline if needed to adjust the fit. Though they may not stain as readily as acrylic dentures, you'll still need to clean them regularly to help them keep looking their best. This also aids in protecting the rest of your mouth from dental disease by removing any buildup of harmful bacterial plaque on the RPD.
But even with these limitations, patients choose RPDs for the simple fact that they're affordable and temporary. And the latter is their greatest benefit—providing you a “bridge” between losing a tooth and replacing it with a durable dental implant.

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.

Remembered fondly by fans as the wacky but loveable Carlton on The Fresh Prince of Bel-Air, Alfonso Ribeiro is currently in his fifth year hosting America's Funniest Videos. It's the perfect gig for the 48-year-old actor, who loves to laugh and make others laugh as well. This is quite the opposite experience from one he had a few years ago that he remembers all too well: a severely decayed tooth.
After seeing his dentist for an intense toothache, Ribeiro learned he had advanced tooth decay and would need root canal treatment. Ribeiro wasn't thrilled by the news. Like many of us, he thought the procedure would be unpleasant. But he found afterward that not only was the root canal painless, his toothache had vanished.
More importantly, the root canal treatment saved his tooth, as it has for millions of others over the last century. If you're facing a situation similar to Alfonso Ribeiro's, here's a quick look at the procedure that could rescue your endangered tooth.
Getting ready. In preparation for root canal therapy, the tooth and surrounding gums are numbed, often first with a swab of local anesthesia to deaden the surface area in preparation for the injection of the main anesthesia below the surface. A dental dam is then placed to isolate the infected tooth from its neighbors to prevent cross-contamination.
Accessing the interior. To get to the infection, a small access hole is drilled. The location depends on the tooth: in larger back teeth, a hole is drilled through the biting surface, and in front teeth, a hole is drilled on the backside. This access allows us to insert special tools to accomplish the next steps in the procedure.
Cleaning, shaping and filling. Small tools are used to remove the diseased tissue from the interior tooth pulp and root canals. Then the empty spaces are disinfected. This, in effect, stops the infection. Next, the root canals inside the tooth are shaped to allow them to better accept a special filling called gutta percha. The access hole is then sealed to further protect the tooth from future infection, and a temporary crown is placed.
A new crown to boot. Within a couple weeks, we'll cap the tooth with a long-lasting lifelike crown (or a filling on certain teeth). This adds further protection for the tooth against infection, helps strengthen the tooth's structure, and restores the tooth's appearance.
Without this procedure, the chances of a tooth surviving this level of advanced decay are very slim. But undergoing a root canal, as Alfonso Ribeiro did, can give your tooth a real fighting chance.

You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.
