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.

The few teeth your one or two year old has will eventually fall out in a few years—so, why be concerned about tooth decay this early? Actually, you should: Fighting tooth decay should always be a priority, even at this early age.
Even though primary teeth are short-lived, they make a huge impact on future dental health. These early teeth help guide the eruption of permanent teeth—if lost prematurely to decay, the later teeth may come in misaligned and create a poor bite. Preserving them could help you avoid later orthodontic treatment.
Fortunately, you can help prevent decay in your child's primary teeth. Here's how.
Practice oral hygiene even before teeth. You should begin daily oral hygiene, the principal defense against tooth decay, even before their first teeth emerge. You can reduce harmful bacteria in their mouths by wiping their gums with a clean cloth after nursing. When teeth appear, begin brushing with just a smear of toothpaste.
Limit sugar consumption. Because decay-causing bacteria thrive on sugar, reduce your child's intake in snacks and beverages. For example, don't put them down for bed with a bottle filled with a sugary liquid like juice, sweetened drinks or even formula or breast milk. If you do give them a night-time bottle, fill it only with water.
Avoid bacterial transfer. Your child's immature immune system can't handle the same level of bacteria as in your mouth. So, reduce the chances of bacterial transfer that may cause tooth decay by avoiding kissing on the mouth or sharing eating or drinking utensils with your infant.
Begin dental visits early. Even though they may have few teeth by their first birthday, it's still a good time to begin your child's regular dental visits. Your dentist may be able to diagnose decay early (and treat for maximum effectiveness), as well as provide sealants, topical fluoride and other measures for preventing decay.
Tooth decay at an early age could impact your child's future dental health. Taking steps now to reduce it could help ensure they have healthy teeth and gums later in life.

You could have an unattractive smile because of a chipped tooth or one slightly out of alignment. Or, it could be both of the above, plus some heavy staining to boot. Correcting each flaw individually might require a combination of different methods like orthodontics or porcelain crowns, which can take an extended period of time to complete.
But you may be able to correct numerous smile flaws with just one method—and in no more than a couple of treatment visits. It's called direct veneers.
Unlike regular veneers, direct veneers don't require a dental technician to craft a thin porcelain shell to bond over teeth. Rather, a dentist applies a tooth-colored material called composite resin to the problem teeth and "sculpts" an entirely new look that can correct multiple dental flaws at one time.
The dentist usually begins the process by creating a model ("wax-up") of proposed changes based on physical impressions of the jaw and teeth. Both dentist and patient can study the model and modify it if necessary, when finalizing the treatment plan.
At a subsequent appointment, the dentist prepares the tooth surface for bonding by removing a thin layer of tooth enamel, then shapes the teeth to better accommodate the composite resin. This tooth prep is similar to that done with traditional veneers, so it's permanent—the teeth will require some form of restoration from then on.
After applying an etchant and a bonding agent, the dentist applies the composite resin in small amounts, hardening each layer with a special light before applying the next one. With each subsequent layer, the dentist sculps the composite material to eventually resemble the wax-up model.
After completing the composite application, the dentist then uses hand tools and a dental drill to complete shaping, as well as an abrasive strip between teeth to aid future flossing. After just a few hours, the transformation is complete.
Direct veneers are durable, but not to the same extent as regular veneers or other cosmetic enhancements. They can also pick up stains over time, and may require re-treatment at some point. Still, direct veneers are a cost-effective way to improve the appearance of teeth with multiple flaws that could radically change your smile for the better.
