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.

Although techniques and materials have changed, dentists still follow basic principles for treating tooth decay that date from the late 19th Century. And for good reason: They work. These principles first developed by Dr. G.V. Black—the "father of modern dentistry"—are widely credited with saving millions of teeth over the last century.
One of the most important of these treatment protocols is something known as "extension for prevention." In basic terms, it means a dentist removes not only decayed tooth structure but also healthy structure vulnerable to decay. But although effective in saving teeth, practicing this principle can result in loss of otherwise healthy tissue, which can weaken the tooth.
But with new advances in dentistry, decay treatment is getting an overhaul. While Dr. Black's time-tested protocols remain foundational, dentists are finding new ways to preserve more of the tooth structure in a concept known as minimally invasive dentistry (MID).
Better diagnostic tools. Because tooth decay can ultimately infect and damage the tooth's interior, roots and supporting bone, the best way to preserve more of the tooth structure is to treat it as early as possible. Now, new diagnostic tools like digital x-rays, microscopic magnification and optical scanning are helping dentists detect and treat decay earlier, thus reducing how much tissue is removed.
Better prevention methods. Oral hygiene and regular dental care are our basic weapons in the war with tooth decay. In addition, utilizing topical fluoride in combination with a milk-derived product called CPP-ACP dentists can get more of the cavity-fighting organic compound into the tooth enamel to strengthen it against acid attack.
Better treatment techniques. Using air abrasion (a fine particle spray that works like a miniature sandblaster) and lasers, dentists can now remove decayed structure with less harm to healthy tissue than with a traditional dental drill. And new, stronger dental fillings like those made with composite resins require less structural removal to accommodate them.
With these innovative approaches, dentists aren't just saving teeth, they're preserving more of their structure. And that can improve your overall dental health for the long-term.

Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
While dental diseases tend to be a greater concern as we get older, they also pose a potential threat to children. A particular type of tooth decay called early childhood caries (ECC) can severely damage children's unprotected teeth and skew their normal dental development.
Fortunately, you can protect your child's teeth from disease with a few simple practices. First and foremost: start a hygiene habit as soon as possible to remove disease-causing bacterial plaque. You don't have to wait until teeth appear, either: simply wipe the baby's gums with a clean wet cloth after nursing to minimize the growth of oral bacteria.
When their teeth do begin to erupt, you can switch to brushing (you can add flossing as more teeth erupt—but until the child shows appropriate dexterity, you'll need to do it for them). For infants, brush gently but thoroughly with a soft-bristled brush and a smear of fluoride toothpaste. When they grow older you can increase the toothpaste to a pea-sized amount. And as soon as you can, get them involved with learning to perform these vital habits on their own.
You should also limit your child's consumption of sugar. Our favorite carbohydrate is also a favorite of bacteria, who consume any remnants in dental plaque as a primary food source. So, keep sugary snacks and foods to a minimum and limit them mainly to mealtimes. And don't put a baby to sleep with a bottle filled with a liquid containing sugar (including formula and breastmilk).
Finally, begin taking your child to the dentist regularly by their first birthday for routine cleanings and checkups. Besides removing any hard to reach plaque, your dentist may also apply sealants and topical fluoride to help protect and strengthen tooth enamel. Regular visits make it more likely to detect the early signs of decay, before it does extensive damage. And beginning early makes it less likely your child will develop a fear of dental visits that could carry on into adulthood.
These and other steps will go a long way in protecting your child's teeth and gums so they develop normally. A little prevention and protection will help ensure a happy, healthy smile later in life.

If your dentist found tooth decay on your last visit, you might have been surprised. But tooth decay doesn't occur suddenly—it's a process that takes time to unfold.
It begins with bacteria—too many, that is. Bacteria naturally live in the mouth, but when their populations grow (often because of an abundance of leftover sugar to feed on) they produce high amounts of acid, a byproduct of their digestion. Too much acid contact over time softens and eventually erodes tooth enamel, making decay easier to advance into the tooth.
So, one important strategy for preventing tooth decay is to keep your mouth's bacterial population under control. To do that, here are 4 common-sense tactics you should perform between dental visits.
Practice daily hygiene. Bacteria thrive in dental plaque, a thin film of food particles that builds up on teeth. By both brushing and flossing you can reduce plaque buildup and in turn reduce disease-causing bacteria. In addition, brushing with a fluoride toothpaste can also help strengthen tooth enamel against acid attacks.
Cut back on sugar. Reducing how much sugar you eat—and how often –deprives bacteria of a prime food source. Constant snacking throughout the day on sweets worsens the problem because it prevents saliva, the body's natural acid neutralizer, from reducing high acid levels produced while eating. Constant snacking doesn't allow saliva to complete this process, which normally takes about thirty minutes to an hour. To avoid this scenario, limit any sweets you eat to mealtimes only.
Wait to brush after eating. Although this sounds counterintuitive, your tooth enamel is in a softened state until saliva completes the acid neutralizing process previously described. If you brush immediately after eating you could brush away tiny particles of softened enamel. Instead, rinse your mouth out with water and wait an hour for saliva to do its work before brushing.
Boost your saliva. Inadequate saliva flow could inhibit the fluid's ability to adequately neutralize acid or provide other restorative benefits to tooth enamel. You can improve flow with supplements or medications, or by drinking more water during the day. Products with xylitol, a natural sugar alternative, could give you a double benefit: chewing gums and mints containing it could stimulate more saliva flow and the xylitol itself can inhibit bacterial growth.
