AlthoughRareThisConditionCouldDestroyaTooth

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.

AdultToothRootResorptionisaSeriousIssuethatRequiresPromptAction

Tooth decay and periodontal (gum) disease pose the most common dangers to dental health. But there are some rare conditions that can also place teeth at risk to be on the lookout for during regular dental checkups.

One such condition is root resorption in an adult tooth, in which the root itself or its surface breaks down and is absorbed by the body. Resorption occurs naturally in a primary (“baby”) tooth so it can loosen and give way for an incoming permanent tooth.  Resorption still occurs in a limited form with young permanent teeth but should eventually stop.

Sometimes, though, it doesn’t, either from the inside of the tooth out (internal resorption) or more often from the outside in, usually around the neck-like (or “cervical”) portion of the tooth. This more common occurrence, External Cervical Resorption (ECR), can first appear as pink spots on the enamel and then progress into cavity-like areas. If not found and treated promptly, damage can occur quickly and lead to tooth loss.

We don’t fully understand the exact nature and causes for ECR, but we have identified risk factors for its development. Excessive orthodontic force on the teeth or any other trauma can cause damage to the periodontal ligament (which holds teeth in place with the jaw bone). Teeth grinding habits and some dental procedures like internal tooth whitening can also be risk factors.That being said, though, the vast majority of people who experience these issues don’t develop ECR.

Although the causes aren’t fully understood, we can still treat it: the key to success is early detection. You probably won’t notice early signs of ECR, but we can often detect spots from routine x-rays. We can then remove the tissue cells within the lesions causing the damage and restore the area with a tooth-colored filling material. If ECR has extended near the tooth’s interior pulp layer, then a root canal treatment may be needed.

Needless to say, the more extensive ECR occurs in the roots, the less likely the tooth can be saved and may need to be extracted. It’s important, therefore, to maintain regular dental checkups (at least twice a year) to increase your chances of catching a developing problem early.
