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.

Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

While pregnancy is an exciting time for expectant mothers, it can pose extra health challenges. This is especially true regarding dental health.
Because of hormonal changes that naturally occur during pregnancy, your teeth and gums are at higher risk for dental disease. These changes can increase cravings for carbohydrates, particularly sugar. Increased sugar consumption feeds bacteria found in dental plaque, which is most responsible for tooth decay and periodontal (gum) disease.
Hormonal changes can also make your gums more susceptible to infection. Conditions may be favorable for a form of gum disease called pregnancy gingivitis, which can begin as an infection in the surface layers of the gums. But like other forms of gum disease, pregnancy gingivitis can advance below the gum line and lead to serious health consequences.
Because of this "pregnancy effect" on your teeth and gums, there are some things to which you should pay heed while you're expecting. First and foremost, keep up a daily regimen of brushing and flossing to remove accumulated dental plaque. You should also control your sugar intake to minimize bacterial growth that can cause disease.
It's also important for you to continue regular dental visits during your pregnancy. Your dentist will monitor your dental health and initiate treatment if you begin to show signs of disease. Besides professional cleanings, your dentist may also prescribe antibacterial mouthrinses to combat bacteria.
As far as dental procedures, essential treatments like fillings, root canals or extractions are usually considered safe to perform during pregnancy. But elective treatments of a cosmetic nature are best postponed until after your baby's delivery.
One last tip: because of the higher risk of tooth decay or gum disease, be on the lookout for any abnormal signs in your mouth. This includes spots on the teeth, tooth pain or swollen, reddened or bleeding gums. If you see any of these signs, see your dentist as soon as possible.
Your teeth and gums are indeed at risk for disease during pregnancy. But daily hygiene, regular dental care and attention to signs of disease can help keep that danger at bay.
