Humanity has been waging war against tooth decay for millennia — with this relentless opponent often getting the better of us.
Over the last century, however, significant treatment advances have turned the tide of battle in our favor. Perhaps the greatest of these advancements is our deeper grasp of the disease process — new understandings that have altered our treatment strategy. Rather than wait for cavities to occur and then repair the damage, we now focus on stopping the damage from occurring in the first place.
Prevention starts by reducing factors that contribute to tooth decay. We can signify these detrimental factors with the acronym BAD:
Bad Bacteria. Millions of bacteria inhabit our mouths at any one time, but only a few strains produce the acid that causes decay. We want to reduce their population by removing dental plaque (where they feed and grow) through daily brushing and flossing, and, at a minimum, semi-annual office cleanings.
Absence of Saliva. This important fluid neutralizes acid and strengthens tooth enamel. Some people, however, suffer from reduced saliva flow. We want to find the cause (for example, a side effect of certain prescription drugs) and then improve saliva flow.
Dietary Habits. A diet heavy in sugar and acid (particularly sodas and soft drinks) gives bacteria a ready food source and increases the mouth’s acidic level. Chronic high acid levels in particular are often too great for normal saliva flow to overcome and neutralize. Reducing the amount and frequency of these food items creates a healthier oral environment.
Reducing BAD factors is only half of our prevention focus. We also want to promote SAFE factors that enhance tooth health and strength: Sealants, especially for children, that shield tooth surfaces from decay; Antimicrobial rinses that target and rid the mouth of acid-producing bacteria and give healthy bacteria room to develop; Fluoride, a proven enamel-strengthening chemical available in dental products, many drinking water systems and as a topical application in dental offices; and an Effective diet that’s rich in nutrients and low in sugar and acid as already mentioned.
Keeping the focus on reducing BAD factors and promoting SAFE factors will greatly increase your chances of personally winning the war against tooth decay.

If you're one of the more than 26 million people in the U.S. with diabetes, you know first hand how the disease impacts your life. That includes your dental health — and whether or not implants are a good tooth replacement option for you.
Diabetes is actually the name for a group of diseases affecting how your body processes glucose, a simple sugar that provides energy for the body's cells. The level of glucose in the blood is regulated by insulin, a hormone produced in the pancreas. Diabetes causes the pancreas to either stop producing insulin (Type 1) or not produce enough (Type 2). Also in Type 2, the body can become unresponsive to the insulin produced.
The implications for either type are serious and can be life-threatening. If glucose levels are chronically too low or high the patient could eventually go blind, suffer nerve damage, or develop kidney disease. Diabetes also interferes with wound healing and creates a greater susceptibility for gangrene: diabetics thus have a higher risk for losing fingers, toes and limbs, and can even succumb to coma or death.
Type 2 is the most common form of diabetes. Fortunately, most people with this type can effectively manage it through diet, exercise and regular glucose monitoring; if need be, prescription medication can help regulate their levels. Even so, diabetics with their disease under control must still be alert to slower wound healing and a higher risk of infection.
Because implant placement is a minor surgical procedure, the aspects of diabetes related to healing, infection and inflammation could have an adverse impact on the ultimate success of the placement. Implant surgery creates a wound in the surrounding gum tissues and bone that will need to heal; the body's immune response in a diabetic can interfere with that process. And if infection sets in, the risks of implant failure increase.
But research has shown that diabetics with good glucose management have as high a success rate (over 95% after ten years) as non-diabetic patients. That means the implant option is a viable one for you as a diabetic — but only if you have your disease under control.
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.
