Along with the gums, your teeth’s roots help stabilize them. Without them your teeth couldn’t handle the normal biting forces you encounter every day. That’s why a rare condition called root resorption must be treated promptly: this gradual breakdown and dissolving of root structure could eventually cause you to lose your tooth.
Resorption is normal in primary (“baby”) teeth giving way for permanent teeth or sometimes during orthodontic treatment. But the form of resorption we’re referring to in permanent teeth isn’t normal, and is highly destructive.
The condition begins in most cases outside the tooth and works its way in, usually at the gum line around the cervical or “neck-like” region of the tooth (hence the term external cervical resorption or ECR). ECR produces pink spots on the teeth in its early stages: these are spots of weakened enamel filled with pink-colored cells that cause the actual damage. The cells create cavity-like areas that can continue to enlarge.
We don’t fully understand what causes ECR, but there seems to be links with excessive force during orthodontics, tooth trauma (especially to the gum ligaments), tooth grinding habits or internal bleaching procedures. However, most people with these problems don’t develop ECR, so the exact mechanism remains a bit of a mystery.
The good news, though, is that we can treat ECR effectively, provided we discover it before it inflicts too much damage. That’s why regular dental visits are important, coupled with your own observation of anything out of the ordinary and immediate dental follow-up.
If the affected area is relatively small, we may be able to remove the cells causing the damage and repair the area with a tooth-colored filling. If it appears the pulp (the tooth’s innermost layer) is involved, we may need to perform a root canal treatment to remove infected tissue and fill the empty space with a special filling. You may also need other procedures to reduce the chances of gum recession around the affected tooth.
Proactive dental care is your best insurance against losing a tooth to root resorption. So keep an eye on your teeth and see your dentist regularly to keep your teeth and gums healthy.

While out with friends one evening, you take a bite of ice cream. Suddenly, pain shoots through your teeth. It only lasts a second, but it's enough to ruin your good time.
This could be tooth sensitivity, a painful reaction to hot or cold foods. It often occurs when the enamel in prolonged contact with acid has eroded. Acid is a waste product of bacteria found in plaque, a thin film of food particles that builds up on tooth surfaces due to inadequate brushing and flossing. Enamel normally mutes temperature or pressure sensation to the underlying dentin layer and nerves. Loss of enamel exposes the dentin and nerves to the full brunt of these sensations.
Sensitivity can also happen if your gums have shrunk back (receded) and exposed dentin below the enamel. Although over-aggressive brushing can often cause it, gum recession also happens because of periodontal (gum) disease, a bacterial infection also arising from plaque.
The best way to avoid tooth sensitivity is to prevent enamel erosion or gum recession in the first place. Removing accumulated plaque through daily brushing and flossing is perhaps the most essential part of prevention, along with a nutritious diet low in sugar and regular dental cleanings and checkups.
It's also important to treat any dental disease that does occur despite your best hygiene efforts. Gum disease requires aggressive plaque removal, especially around the roots. While receded gum tissues often rebound after treatment, you may need gum grafting surgery to restore lost tissues if the gums have receded more deeply. For enamel erosion and any resulting decay you may need a filling, root canal treatment or a crown, depending on the depth and volume of structural damage.
While you're being treated you can also gain some relief from ongoing sensitivity by using a toothpaste with potassium nitrate or similar products designed to desensitize the dentin. Fluoride, a known enamel strengthener, has also been shown to reduce sensitivity. We can apply topical fluoride directly to tooth surfaces in the form of gels or varnishes.
Don't suffer through bouts of tooth sensitivity any more than you must. Visit us for a full exam and begin treatment to relieve you of the pain and stress.
