StayAheadofDecay-SpreadingRootCavities

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.

3ReasonsForPreservingaDecayedBabyTooth

Tooth decay can be a big problem for children's primary (baby) teeth. It doesn't take long for a tooth to become infected and the infection spread to their neighbors.

But since it will eventually give way to a permanent tooth, why not just pull a diseased primary tooth? Although that sounds sensible, there are important reasons for helping a troubled primary tooth survive to its natural end.

Current usefulness. They may not be around for long, but primary teeth serve children well while they have them. They enable a child to eat solid foods to further their physical development. They also figure prominently in speech development, which could be stunted by lost teeth.

The smile factor. Young children are also honing their social skills, and smiling is an important part of learning to fit in with family and friends. A tooth that's missing for some time, especially in the “smile zone,” could affect their smile and have an adverse effect on their social development.

Future teeth health. A primary tooth reserves the space intended for the future permanent tooth, helping to ensure the incoming tooth erupts in the right position. If it's not there, however, other teeth can drift into the space, crowding the incoming tooth out of its proper alignment.

That last reason could have the most long-term effect, causing the development of a poor bite that could require extensive orthodontic treatment. To avoid this and any other physical or social consequences accompanying its premature loss, it's worth the effort to try to protect and save a primary tooth.

Preventively, we can apply sealants on biting surfaces more prone to plaque buildup (the main cause of decay) and topical fluoride to strengthen enamel. When decay does occur, we may be able to remove it and fill the tooth, cap a tooth with a steel crown, or even use a modified root canal procedure in the case of advanced tooth decay.

The best way, however, to protect your child's primary teeth is to brush and floss them every day. Removing harmful plaque vastly reduces the risk of tooth decay. Coupled with professional dental care, your child can avoid tooth decay and get the most out of their primary teeth.

AddressingRiskFactorsTakingtheFightAgainstToothDecaytoaNewLevel

Tooth decay is more prevalent than diseases like cancer, heart disease or influenza. It doesn't have to be—brushing with fluoride toothpaste, flossing, less dietary sugar and regular dental cleanings can lower the risk of this harmful disease.

Hygiene, diet and dental care work because they interrupt the disease process at various points. Daily hygiene and regular dental cleanings remove dental plaque where oral bacteria flourish. Reducing sugar eliminates one of bacteria's feeding sources. With less bacteria, there's less oral acid to erode enamel.

But as good as these methods work, we can now take the fight against tooth decay a step further. We can formulate a prevention strategy tailored to an individual patient that addresses risk factors for decay unique to them.

Poor saliva flow. One of the more important functions of this bodily fluid is to neutralize mouth acid produced by bacteria and released from food during eating. Saliva helps restore the mouth's ideal pH balance needed for optimum oral health. But if you have poor saliva flow, often because of medications, your mouth could be more acidic and thus more prone to decay.

Biofilm imbalance. The inside of your mouth is coated with an ultrathin biofilm made up of proteins, biochemicals and microorganisms. Normally, both beneficial and harmful bacteria reside together with the “good” bacteria having the edge. If the mouth becomes more acidic long-term, however, even the beneficial bacteria adapt and become more like their harmful counterparts.

Genetic factors. Researchers estimate that 40 to 50 hereditary genes can impact cavity development. Some of these genes could impact tooth formation or saliva gland anatomy, while others drive behaviors like a higher craving for sugar. A family history of tooth decay, especially when regular hygiene habits or diet don't seem to be a factor, could be an indicator that genes are influencing a person's dental health.

To determine if these or other factors could be driving a patient's higher risk for tooth decay, many dentists are now gathering more information about medications, family history or lifestyle habits. Using that information, they can introduce other measures for each patient that will lower their risk for tooth decay even more.

AreLaserstheFutureforTreatingAdvancedToothDecay

Advanced tooth decay is a serious dental problem that can threaten an affected tooth's survival. But for decades now dentists have reliably used root canal treatment to better a decayed tooth's odds. This routine procedure performed with dental drill and special hand tools removes infected tissue inside a tooth and replaces the voids with a filling to prevent future infection.

But now there's a new way to perform a root canal—with a surgical laser. Lasers, amplified and focused light beams, aren't new to healthcare—they're an integral feature of many routine medical treatments and surgeries. But their use is relatively new to dentistry, and to endodontics (treating the interior of teeth) in particular.

Lasers can be used in root canal treatment to perform a number of tasks. They can remove diseased tissue and other debris from the innermost tooth pulp. They can be used to clean and shape root canal walls in preparation for filling. And they can also be used to soften and mold the filling material to fit more precisely within a tooth's particular root canal network.

Although laser-assisted root canal therapy isn't yet widespread, laser's limited use to date has given us a fair picture of both their advantages and disadvantages. As with other medical laser applications, lasers are very precise in removing diseased tissue without too much disruption of healthy tissue. There's less need for anesthesia than with dental drills, and lasers are a lot less noisy and jarring. Patients by and large experience less bleeding, as well as less discomfort or infection afterward.

But because laser light can only travel in a straight line, they're difficult to use in many tightly curved root canals. In these cases, the traditional methods are better suited, although a laser can be used in conjunction with other tasks. Temperature with lasers must also be carefully managed lest the high heat that's often generated damages natural tissues.

Although lasers won't be replacing traditional treatment methods for decayed teeth in the foreseeable future, there's hope they'll become more commonplace as technology and techniques continue to advance. Lasers can only improve what already is an effective means of saving teeth.

KeepYourSalivaFlowing-YourOralHealthDependsonit

We often don't realize how important something is until it's gone. Like saliva: you're usually not aware that it's cleaning the mouth, neutralizing mouth acid or helping with digestion. But that could change if your saliva flow drops below normal: your health may soon suffer with your mouth taking the brunt.

In particular, reduced saliva flow increases your risk for tooth decay and periodontal (gum) disease. Both diseases are linked to oral bacteria. While many of the myriad strains in the mouth are beneficial, a few bacteria can infect and inflame gum tissues. Bacteria also produce acid, which can soften and erode enamel and make the teeth more susceptible to decay.

Saliva inhibits bacteria in a number of ways. It first clears the mouth of leftover food so not as much stays behind to form bacterial plaque, a thin film of food particles that builds up on teeth. You still need to brush and floss daily to remove plaque, but it's less effective without saliva's cleansing action. Saliva also contains antibodies that destroy disease-causing bacteria and other organisms, which keeps their populations in the mouth low.

One of saliva's most important functions, though, is buffering acid. The mouth's ideal pH level is neutral, but many foods we eat can cause it to become more acidic. Even a slight acidic rise after eating can soften the minerals in enamel. But saliva goes to work immediately and usually restores normal pH within a half hour to an hour. It also aids in re-mineralizing the enamel.

For these reasons, it's important for you to find out the cause of chronic dry mouth and treat it. If it's a side effect of your medication, talk to your doctor about an alternative, or drink more water before and after you take your dose. Certain products can also stimulate saliva flow, like chewing gum with xylitol, an alcohol-based sweetener that has dental health-protecting properties too.

Although you often don't notice this unsung bodily fluid swishing in your mouth, it's important that you take care of it. Keeping your saliva flowing will help ensure better oral health.
