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.
There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.

As we get older, we become more susceptible to chronic health conditions like diabetes, heart disease or arthritis. We can also begin to see more problems with our teeth and gums.
Whether it's ourselves or an older loved one, oral health deserves a heightened focus as we age on prevention and prompt treatment. Here's what you can do to protect you or a family member's teeth and gums during the aging process.
Make accommodations for oral hygiene. Keeping your mouth clean of disease-causing plaque is important at any age. But it may become harder for someone getting older: Manual dexterity can falter due to conditions like arthritis or Parkinson's Disease. Older adults with decreased physical ability may benefit from larger gripped toothbrushes or those modified with a bicycle handle. Electric power brushes are another option, as are water irrigators that can do as effective a job of flossing as threaded floss.
Watch out for “dry mouth.” Older adults often develop chronic dry mouth due to saliva-reducing medications they might be taking. It's not just an unpleasant feeling: Inadequate saliva deprives the mouth of acid neutralization. As a result, someone with chronic dry mouth has a higher risk for tooth decay. You can reduce dry mouth by talking with your doctor about prescriptions for you or a family member, drinking more water or using saliva boosting products.
Maintain regular dental visits. Regular trips to the dentist are especially important for older adults. Besides professional cleanings, dentists also check for problems that increase with aging, such as oral cancer. An older adult wearing dentures or other oral appliances also needs to have them checked periodically for any adverse changes to fit or wear.
Monitor self-care. As long as they're able, older adults should be encouraged to care daily for their own teeth. But they should also be monitored in these areas, especially if they begin to show signs of decreased mental or physical abilities. So, evaluate how they're doing with brushing and flossing, and look for signs of tooth decay or gum disease.
Aging brings its own set of challenges for maintaining optimum dental health. But taking proactive steps and acting quickly when problems arise will help meet those challenges as they come.
