Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

Most dental problems arise from tooth decay and periodontal (gum) disease. But they aren't the only source of danger to your teeth—gastroesophageal reflux disease (GERD) could be just as damaging to your tooth enamel as dental disease.
GERD usually occurs when a ring of muscles at the top of the stomach weaken, allowing stomach acid to enter the esophagus. This resulting acid reflux can make life unpleasant and pose potential health dangers—over time it can damage the lining of the esophagus and cause ulcers and pre-cancerous cells. It can also erode tooth enamel if acid enters the mouth and raises its level of acidity.
This can be a problem because acid can soften and dissolve the mineral content of tooth enamel. This is the primary cause of tooth decay as acid produced by oral bacteria attack enamel. The more bacteria present, often thriving in dental plaque, the higher the potential levels of acid that can damage enamel. Stomach acid, which is strong enough to break down food, can cause similar harm to enamel if it causes higher than normal acidity in the mouth.
There are some things you can do to protect your teeth if you have GERD, namely manage your GERD symptoms with lifestyle changes and medication. You may need to avoid alcohol, caffeine or heavily acidic or spicy foods, all known to aggravate GERD symptoms. Quitting smoking and avoiding late night meals might also ease indigestion. And your doctor may recommend over-the-counter or prescription drugs to help control your acid reflux.
You can also boost your teeth's enamel health by practicing daily brushing and flossing—but not right after a reflux episode. The enamel could be softened, so brushing can potentially remove tiny particles of mineral content. Instead, rinse with water mixed with or without a little baking soda to help neutralize acid and wait about an hour—this will give saliva, the mouth's natural acid neutralizer, time to restore the mouth's normal pH level.
And be sure you're using a fluoride toothpaste. Fluoride strengthens enamel—in fact, your dentist may recommend topical fluoride applications to boost the effect.
These and other tips can help minimize the effects of GERD on your dental health. With an ounce of prevention, you can keep it from permanently damaging your teeth.

A root canal treatment is a common procedure performed by dentists and endodontists (specialists for inner tooth problems). If you're about to undergo this tooth-saving procedure, here's what you need to know.
The goal of a root canal treatment is to stop tooth decay within a tooth's interior and minimize any damage to the tooth and underlying bone. This is done by accessing the tooth's pulp and root canals (tiny passageways traveling through the tooth roots to the bone) by drilling into the biting surface of a back tooth or the "tongue" side of a front tooth.
First, though, we numb the tooth and surrounding area with local anesthesia so you won't feel any pain during the procedure. We'll also place a small sheet of vinyl or rubber called a dental dam that isolates the affected tooth from other teeth to minimize the spread of infection.
After gaining access inside the tooth we use special instruments to remove all of the diseased tissue, often with the help of a dental microscope to view the interior of tiny root canals. Once the pulp and root canals have been cleared, we'll flush the empty spaces with an antibacterial solution.
After any required reshaping, we'll fill the pulp chamber and root canals with a special filling called gutta-percha. This rubberlike, biocompatible substance conforms easily to the shape of these inner tooth structures. The filling preserves the tooth from future infection, with the added protection of adhesive cement to seal it in.
Afterward, you may have a few days of soreness that's often manageable with mild pain relievers. You'll return for a follow-up visit and possibly a more permanent filling for the access hole. It's also likely you'll receive a permanent crown for the tooth to restore it and further protect it from future fracture.
Without this vital treatment, you could very well lose your tooth to the ravages of decay. The time and any minor discomfort you may experience are well worth the outcome.

The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
Over the last century dentistry has acquired the knowledge, techniques and treatments to prevent or minimize tooth decay. With this enhanced knowledge we’ve amassed a wealth of data about what increases dental disease development and what prevents it.
This has produced a balanced approach to identifying and treating disease-causing factors and incorporating factors that inhibit tooth decay. Known as Caries Management By Risk Assessment (CAMBRA), this approach first identifies each patient’s individual set of risk factors for dental disease and then develops a customized prevention and treatment plan to minimize their risk.
Rather than simply reacting to occurrences of tooth decay — “drill and fill” — CAMBRA anticipates and targets your susceptibility to decay. The primary factors can be represented by the acronym BAD: Bad bacteria, particular strains that produce acid, which at high levels erode enamel and expose the teeth to infection; Absence of saliva, or “dry mouth,” an insufficient flow of saliva that can’t effectively neutralize acid and restore mineral content to enamel; and Dietary habits too heavy in sugar or acid, which can result in bacterial growth and enamel erosion.
With an accurate picture of your particular risk level we can then apply countering factors from the other side of the balance — those that protect teeth from decay. In this case, we use the acronym SAFE: stimulating Saliva flow when needed or applying Sealants on chewing surfaces most susceptible to decay; Antimicrobials that reduce unhealthy bacteria levels and give healthy bacteria an opportunity to thrive; incorporating Fluoride, a chemical known to strengthen enamel, through hygiene products or direct application to the teeth; and an Effective diet, low in sugar and acid and high in fresh fruits, vegetables and whole grains.
There are a number of preventive and treatment measures that fall into each of the four preventive factors. Using the CAMBRA approach we can develop a treatment and prevention plan that incorporates measures that uniquely fit your dental health situation. With such a plan we can greatly reduce your risk of disease development and impact and better ensure a long and healthy life for your teeth and gums.
