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.

Baby (primary) teeth look and function much like their permanent counterparts. Besides having a visible crown, they also have roots that maintain contact with the jawbone.
But there are some differences, the biggest one being the normal process whereby primary tooth roots dissolve or, in dental terms, resorb. Root resorption eventually leads to the tooth coming loose to make way for the permanent tooth.
Adult tooth roots can also resorb — but it's decidedly not normal. If adult root resorption isn't promptly treated, it could also lead to tooth loss — but there won't be an incoming tooth to take its place.
Although it can begin inside a tooth, adult root resorption usually begins on the outside. One type, external cervical resorption (ECR), begins around the neck-like area of the tooth not far below the gum line. Its initial signs are small pink spots where the tooth enamel has eroded; those pink cells within the space are doing the damage.
We don't fully understand the mechanism behind ECR, but there are some factors that often contribute. People with periodontal ligament damage or trauma, sometimes due to too much force applied during orthodontic treatment, have a high risk of ECR. Some bleaching techniques for staining inside a tooth may also be a factor.
The key to treating ECR is to detect it as early as possible before it does too much root damage. Regular checkups with x-rays play a pivotal role in early detection. Advanced stages of ECR might require more advanced diagnostics like a cone beam computed tomography (CBCT) scan to fully assess the damage.
If the lesion is small, we can surgically remove the cells causing the damage and fill the site with a tooth-colored filling. If ECR has spread toward the pulp, the tooth's inner nerve center, we may also need to perform a root canal treatment.
Either of these methods intends to save the tooth, but there is a point where the damage is too great and it's best to remove the tooth and replace it with a life-like dental implant or other restoration. That's why it requires vigilance through regular, semi-annual dental visits to detect the early signs of root resorption before it's too late.
