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.
If you were asked to identify the number one mouth problem affecting dental health, what would you name? Toothaches? Poor hygiene? Jaw joint issues?
Believe it or not, the top issue among 15,000 respondents in a recent American Dental Association (ADA) survey was dry mouth. A full one-third of the respondents had experienced chronic lack of normal saliva flow; difficulty biting and tooth pain, took second and third place, respectively.
We’ve all experienced the discomfort of temporary dry mouth when we first wake up in the morning or after eating certain foods. But chronic dry mouth is much more serious with long-term effects on a person’s teeth and gum health. This is because among its other important properties, saliva helps neutralize enamel-softening mouth acid and restores minerals to enamel after acid contact. Without sufficient saliva flow you’re much more susceptible to dental disease.
While there are several causes for dry mouth, perhaps the most common is as a side effect to at least five hundred known medications. Because older people tend to take more medications than other age groups, dry mouth is an acute problem among people over 60 (a major factor for why dry mouth took the survey’s top health problem spot).
You can help ease dry mouth from medications by first asking your doctor about switching to alternative medications that don’t affect saliva production. If not, be sure to drink more water during the day and especially when you take your oral medication (a few sips before and after).
You can help your dry mouth symptoms from any cause by drinking more water, limiting your consumption of alcohol or caffeine, and avoiding tobacco products. You can also use substances that stimulate saliva flow—a common one is xylitol, an alcohol-based sugar that’s used as a sweetener in certain gums and candies. Not only does xylitol boost saliva flow it also inhibits the growth of bacteria and thus decreases your risk of disease.
And speaking of reducing bacteria and their effects, don’t neglect daily brushing and flossing. These habits, along with regular dental cleanings and checkups, will benefit you just as much as your efforts to reduce dry mouth in avoiding dental disease.
