Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.

You've just finished your daily brushing and flossing. How did you do? Swiping your tongue across your teeth can generally tell you: It's a good sign if it glides smoothly; but if it feels rough and gritty, you better take another run at it.
This "tongue test," however, only gives you a rough idea of how well you're removing plaque, that thin bacterial film on teeth most responsible for dental disease. Plaque, though, can be sneaky, "hiding" in the nooks and crannies on the biting surfaces of teeth, around the gum line and in between teeth.
So, how do you know if you're clearing out any plaque holdouts? An effective way is to use a plaque disclosing agent. This over-the-counter dental product consists of a swab, tablet or solution, which contains a dye that's reactive to plaque.
After brushing and flossing as usual, you apply the solution to your teeth for about 30 seconds. You then take a look in the mirror: Any remaining plaque will be stained a bright color that makes it stand out. There are also agents with two colors of dye, one that stains older plaque and one for newer plaque.
The plaque staining not only helps you see how well you've been brushing and flossing, it can also show you areas in need of improved hygiene. For example, if you notice a scalloped pattern around the gum line, that may mean your brush isn't getting into that area effectively. In this way, you can use a disclosing agent to fine-tune your hygiene.
Repeated use of a disclosing agent is safe, but just remember the dye color can be vivid. It does wear off in a few hours, though, so perhaps schedule it for a day off around the house. You should also avoid swallowing any solution or getting any of it on clothing.
The ultimate test, though, is a thorough dental cleaning with your dentist at least every six months. They can verify whether you've been fairly successful with your brushing and flossing, or if you have room for improvement. If you do use a disclosing agent, you can also discuss that with them in working out better strategies to protect your teeth from tooth decay and gum disease.

We're all tempted occasionally to use our teeth in ways that might risk damage. Hopefully, though, you've never considered anything close to what singer, songwriter and now social media persona Jason Derulo recently tried in a TikTok video—attempting to eat corn on the cob spinning on a power drill. The end result seemed to be a couple of broken front teeth, although many of his followers suspected an elaborate prank.
Prank or not, subjecting your teeth to “motorized corn”—or a host of other less extreme actions or habits—is not a good thing, especially if you have veneers, crowns or other dental work. Although teeth can withstand a lot, they're not invincible.
Here, then, are four things you should do to help ensure your teeth stay healthy, functional and intact.
Clean your teeth daily. Strong teeth are healthy teeth, so you want to do all you can to prevent tooth decay or gum disease. Besides semi-annual dental cleanings, the most important thing you can do is to brush and floss your teeth daily. These hygiene tasks help remove dental plaque, a thin biofilm that is the biggest culprit in dental disease that could weaken teeth and make them more susceptible to injury.
Avoid biting on hard objects. Teeth's primary purpose is to break down food for digestion, not to break open nuts or perform similar tasks. You should also avoid habitual chewing on hard objects like pencils, nails or ice to relieve stress. And, you may need to be careful eating apples or other foods with hard surfaces if you have veneers or composite bonding on your teeth.
Wear a sports mouthguard. If you or a family member are regularly involved with sports like basketball, baseball/softball or football (even informally), you can protect your teeth from facial blows by wearing an athletic mouthguard. Although you can obtain a retail variety in most stores selling sporting goods, a custom-made guard by a dentist offers the best protection and comfort.
Visit your dentist regularly. As mentioned before, semi-annual dental cleanings help remove hidden plaque and tartar and further minimize your risk of disease. Regular dental visits also give us a chance to examine your mouth for any signs of decay or gum disease, and to check on your dental health overall. Optimizing your dental health plays a key part in preventing dental damage.
You should expect an unpleasant outcome involving your teeth with power tools. But a lot less could still damage them: To fully protect your dental health, be sure you practice daily oral care, avoid tooth contact with hard objects and wear a mouthguard for high-risk physical activities.
