As a new permanent tooth develops, the roots undergo a process of breakdown and growth. As older cells dissolve (a process called resorption), they’re replaced by newer cells laid down (deposition) as the jaw develops. Once the jaw development ends in early adulthood, root resorption normally stops. It’s a concern, then, if it continues.
Abnormal root resorption most often begins outside of the tooth and works its way in, beginning usually around the neck-like (or cervical) region of the tooth. Also known as external cervical resorption (ECR), the condition usually shows first as pink spots where the enamel is being undermined. As these spots continue to erode, they develop into cavity-like areas.
While its causes haven’t been fully confirmed, ECR has been linked to excessive pressure on teeth during orthodontic treatment, periodontal ligament trauma, teeth-grinding or other excessive force habits, and bleaching techniques performed inside a tooth. Fortunately, ECR is a rare occurrence, and most people who’ve had these problems won’t experience it.
When it does occur, though, it must be treated as quickly as possible because the damage can progress swiftly. Treatment depends on the size and location of the resorption: a small site can often be treated by surgically accessing the tooth through the gum tissue and removing the offending tissue cells. This is often followed with tooth-colored dental material that’s bonded to the tooth to replace lost structure.
A root canal treatment may be necessary if the damage has extended to the pulp, the tooth’s interior. However, there’s a point where the resorption becomes too extensive to save the tooth. In these cases, it may be necessary to remove the tooth and replace it with a dental implant or similar tooth restoration.
In its early stages, ECR may be difficult to detect, and even in cases where it’s been diagnosed more advanced diagnostics like a CBCT scanner may be needed to gauge the extent of damage. In any case, it’s important that you have your teeth examined on a regular basis, at least twice a year. In the rare chance you’ve developed ECR, the quicker it’s found and treatment begun, the better your chances of preserving the tooth.
Sometimes, we all need a bit of prompting to do what's good for us. When Serena Girardi, the 10-year-old daughter of New York Yankees manager Joe Girardi, needed to have orthodontic treatment, she was a little nervous. To help lessen her anxiety, Girardi, then 45 years old, made a deal: if she got braces, then he would too.
“What I didn't realize,” said Girardi in an interview with ESPN, “is that she only had to get four on her front teeth and I got the full mouthful.”
But that didn't stop the baseball great from keeping up his end of the bargain. In a separate deal with his son Dante, who also needed braces, Girardi agreed to wear blue rubber bands. “It's a good look,” he said. What will he do if his third child needs braces? Stay tuned...
Whether it starts as a bargain with your kids or as a promise to yourself, orthodontic treatment can offer real benefits at any age. In fact, about one out of five orthodontic patients today is an adult. Studies have shown that up to three-quarters of all adults have some form of orthodontic problem, like drifting or crowding of teeth. And having a great-looking smile not only improves self-confidence, but can also boost an adult's social life, and even enhance his or her career opportunities.
If you or your child may need braces, but you're put off by the dreary metal hardware you remember from back in the day, take heart! Plenty has changed in the field of orthodontics since you were a teenager — and it's not just the color of the rubber bands.
In many cases, clear or colorless ceramic braces can be used instead of metal ones. These stain-resistant orthodontic appliances blend in well with your own teeth, making them much less evident. It may be possible for them to be placed on the lingual (tongue) side of the teeth, where they're even less visible.
Clear aligners offer an alternative to braces that's appropriate for some people. Aligners are a series of precision-made “trays” composed of polyurethane plastic. Worn 20-22 hours per day for a period of months, these appliances gradually move teeth into an improved position. Besides being virtually invisible, another advantage of these trays is that they may be removed for eating and for important occasions. Once recommended only for adults, they have recently become available to teenagers as well.
