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.

If you suffer frequent sinus infections, you might want to see a dentist. No, really—your recurring sinusitis might stem from a decayed tooth.
Tooth decay can start as a cavity, but left untreated can advance within the tooth and infect the pulp and root canals. If it reaches the end of the root, it can cause the root tip and surrounding bone to break down.
A severe toothache is often a good indicator that you have advanced tooth decay, which can usually be stopped with a root canal treatment. But a decayed tooth doesn't always produce pain or other symptoms—you could have a “silent” infection that's less likely to be detected.
A symptomless, and thus untreated, infection in an upper back tooth could eventually impact the maxillary sinus, a hollow air-filled space located just above your back jaw. This is especially true for people whose tooth roots extend close to or even poke through the sinus floor.
That “silent” infection in your tooth, could therefore become a “loud” one in the sinuses causing chronic post-nasal drip, congestion and, of course, pain. Fortunately, a physician or an ear, nose and throat (ENT) specialist might suspect a dental origin for a case of recurring sinusitis, a condition known as maxillary sinusitis of endodontic origin (MSEO).
Antibiotic treatment can clear up sinusitis symptoms short-term. It's unlikely, though, it will do the same for a dental infection, which may continue to trigger subsequent rounds of sinusitis. The best approach is for a dentist, particularly a specialist in interior tooth disease called an endodontist, to investigate and, if a decayed tooth is found, treat the source of the infection.
As mentioned earlier, the solution is usually a root canal treatment. During this procedure, the dentist completely removes all infected tissue within the pulp and root canals, and then fills the empty spaces to prevent future infection. In one study, root canal therapy had a positive effect on alleviating sinusitis in about half of patients who were diagnosed with a decayed tooth.
If your sinusitis keeps coming back, speak with your doctor about the possibility of a dental cause. You may find treating a subsequently diagnosed decayed tooth could alleviate your sinus problem.

“Cut down on sweets, especially between meals” is perhaps one of the least popular words of advice we dentists regularly give. We’re not trying to be killjoys, but the facts are undeniable: both the amount and frequency of sugar consumption contributes to tooth decay. Our concern isn’t the naturally occurring sugars in fruits, vegetables, grains or dairy products, but rather refined or “free” sugars added to foods to sweeten them.
The World Health Organization and the U.S. Food and Drug Administration both advise consuming no more than 50 grams (about ten teaspoons) of sugar a day. Unfortunately, our nation’s average per person is much higher: we annually consume around 140 pounds per capita of refined sugars like table sugar or high fructose corn syrup, more than three times the recommended amount. Soft drinks are the single largest source of these in our diets — Americans drink an average of 52 gallons every year.
The connection between sugar and tooth decay begins with bacteria that ferments sugar present in the mouth after eating. This creates high levels of acid, which causes the mineral content of tooth enamel to soften and erode (a process called demineralization) and makes the teeth more susceptible to decay. Saliva naturally neutralizes acid, but it takes about thirty minutes to bring the mouth’s pH to a normal level. Saliva can’t keep up if sugars are continually present from constant snacking or sipping on soft drinks for long periods.
You can reduce the sugar-decay connection with a few dietary changes: limit your intake of sugar-added foods and beverages to no more than recommended levels; consume sweets and soft drinks only at meal times; replace sugar-added foods with fresh fruits and vegetables and foods that inhibit the fermentation process (like cheese or black and green teas); and consider using mint or chewing gum products sweetened with xylitol, a natural alcohol-based sugar that inhibits bacterial growth.
Last but not least, practice good oral hygiene with daily brushing and flossing, along with regular office cleanings and checkups. These practices, along with limits on refined sugar in your diet, will go a long way toward keeping your teeth and mouth healthy and cavity-free.

Did you know that tooth decay (dental caries) is the second most frequently occurring disease — surpassed only by the common cold? It can start as soon as toddlers sprout their first teeth and by middle age, more than 90% of adults are affected by the problem! Fortunately, you can significantly lower your risk for decay. The key is to nurture health-promoting (protective) factors in your mouth while discouraging those that are disease causing (pathologic).
The top two traditional steps can't be stressed enough:
Good Oral Hygiene. Diligent brushing and flossing, along with routine professional cleanings, help limit a buildup of bacterial plaque (biofilm). This whitish film is attractive to decay-producing bacteria (among the many types of bacteria — including beneficial ones — that normally live in the mouth). These microbes like to snack on sugars and carbohydrates (perhaps part of that bagel you had for breakfast or the midafternoon candy bar), and in the process they produce acid. A healthy oral environment has a neutral pH — a perfect balance between acids and bases. But in a more acidic environment, minerals in the protective enamel of your teeth start to dissolve, exposing the dentin and root surfaces underneath that are even more vulnerable.
Sensible Diet. Keep decay-producing bacteria in check by limiting your intake of sugars and carbohydrates; the bacteria need these nutrients to grow and reproduce. Choose products containing natural sugars, such as those in fruits and vegetables, over those containing added sugars, such as sodas and candy. Be aware that Xylitol, an “alcohol sugar” used in some chewing gums and dental products, can actually help reduce pathogenic bacteria. And don't forget that frequent consumption of acidic foods and beverages, such as sipping coffee during the day, can create an acidic environment in your mouth that can contribute to decay by eroding tooth enamel and weakening its defenses.
Individual Risk Factors
You also may have individual risk factors as well that our office can help you identify and address. For example, the shape of everyone's teeth varies and some of us have more valleys, tiny grooves and pits than others. These likely places for bacteria to congregate can be the most difficult to reach with a toothbrush, but invisible sealants can be applied to prevent bacteria from reaching those areas.

Given the fact that baby-boomers are now reaching the age of retirement, understanding senior healthcare is becoming a top priority to many people. Discover your level of expertise in the area of oral health by taking the following true/false test.
True or False Self Assessment
- All people eventually lose their teeth as they age.
- Yellow teeth are a sign of gum disease.
- If you have dentures, you no longer need regular dental check-ups.
- Periodontal (gum) disease is a big problem that affects 3 out of 4 adults.
- Electric toothbrushes can be a great option for seniors with arthritis or other debilitating conditions.
- False: Your teeth are meant to last your lifetime.
- False: Yellow teeth typically denote stained teeth from diet, medication, smoking, or growing older. And while they may not appear attractive, older, yellow teeth can in fact be healthy and free of gum disease. However, if your yellow teeth bother you, ask us if teeth whitening could be right for freshening up your smile while making you appear younger.
- False: For those individuals who wear complete upper and lower dentures, you will always need routine dental exams, typically once a year so that you can be screened for cancer, as well as other oral conditions (i.e. candadiasis), to ensure the you obtain and maintain optimal oral health.
- True: 75% of all adults over the age of 35 will experience some form of periodontal disease, a condition in which the gums become inflamed and infected. If left untreated, gum disease causes the bone that supports the teeth to deteriorate until the teeth are loosened and/or eventually lost (either they fall out on their own or must be removed). On a positive note, you can prevent gum disease by having good oral hygiene that includes flossing daily and brushing at least twice a day with a proper technique and fluoride toothpaste.
- True: Under normal conditions, what matters most is not so much the type of toothbrush used (manual, electric or battery powered toothbrush), but rather how you use it. However, if you are unable to use a manual toothbrush effectively for proper brushing, then a power toothbrush may be able to facilitate proper cleaning more easily.
