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.

After months or even years of radiation or chemotherapy, the words "cancer-free" is music to your ears. Your joy and relief, though, may be tempered by the toll these treatments can take on the rest of your body—including your mouth.
Both of these treatments can destroy healthy tissue along with targeted cancer cells. If the focus has been on the head and neck regions, they could damage the salivary glands to the point that they won't produce adequate saliva flow.
A lack of saliva can have a detrimental effect on your oral health. Saliva buffers and helps lower oral acid levels that soften and erode enamel and increase the likelihood of tooth decay. Saliva also supplies antibodies that fight disease-causing bacteria. Otherwise, bacteria—and the risk for disease—can rapidly grow.
If these or other scenarios occur, you may experience dental damage, even tooth loss. Fortunately, we can restore an injured smile in various ways, including dentures, bridges or dental implants. But we should also attempt to limit the potential damage by taking steps to prevent dental disease during cancer treatment.
The most important of these is to brush and floss daily. Everyone should practice these hygiene tasks to remove disease-causing dental plaque, regardless of their health status. But because some natural disease-fighting mechanisms in the mouth may be disrupted during either radiation or chemotherapy, it's even more important if you're a cancer patient.
It's equally important to maintain as much as possible regular dental visits during cancer treatment. Dental cleanings provided during these visits remove any residual plaque and tartar (hardened plaque), which further lowers your disease risk.
Your dentist can better monitor your overall dental condition during frequent visits and provide as much treatment as you can tolerate. They can also enhance your protection against disease by prescribing antibacterial mouthrinses, fluoride applications or products to boost saliva production.
Some teeth and gum problems may be unavoidable; in that case, you may need post-treatment dental care to restore your oral health as needed. But caring as much for your dental health as you're able during cancer treatment could help you realize a better outcome.
Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.
Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.
To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.
This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.
To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.
You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.
You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.
Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.

While your dentist plays an important role in keeping things inside your mouth healthy, what you do every day often makes the biggest difference. Here are 5 routine things you can do for better oral health.
Brush and floss every day. The most important thing you can do for your teeth and gums is adhere to a daily schedule of brushing and flossing. These twin tasks remove the daily buildup of plaque, a thin bacterial biofilm most responsible for tooth decay and gum disease.
Check your hygiene. There's brushing and flossing—and then there's brushing and flossing effectively. To make sure you're getting the job done, run the tip of your tongue along your teeth after you brush and floss. If it feels smooth, mission accomplished! If it feels rough and gritty, though, try again. You can also use plaque disclosure products occasionally to highlight any missed plaque still on your teeth.
Say no to sugar. Chances are you love sugar—and so do the disease-causing bacteria in your mouth. As they feed on sugar, they multiply and produce acid, which in high levels can erode tooth enamel and lead to tooth decay. Limiting sugar in your diet reduces oral bacteria and the acid they produce, and thus lowers your risk for disease.
Drink plenty of water. Saliva plays an important role in oral health: It helps fight off bacteria, neutralizes acid and re-mineralizes tooth enamel. But it can't do those things if there's not enough of it. So, if your mouth consistently feels dry, drink more water to give your body what it needs to make saliva. Drinking water also washes away food particles that could become plaque and lowers your mouth's acidity.
Maintain your dental appliances. You can extend the life of dentures, retainers or other types of dental appliances by cleaning and maintaining them. You should clean your appliance regularly using regular hand soap or a designated cleaner (not toothpaste, which can be too abrasive). Unless otherwise directed by your dentist, take them out at night and be sure to store them where kids or pets can't get to them.

A scoop of ice cream is one of life's little pleasures. But for one in three Americans, it could be something altogether different—an excruciating pain when cold ice cream meets teeth. This short but painful experience that can happen when dental nerves encounter hot or cold temperatures is called tooth sensitivity.
A look at tooth anatomy will help explain why. Teeth are mainly composed of outer enamel, a layer of nerves and blood vessels within the tooth called the pulp, and dentin, a porous layer in between. The pulp nerves pick up temperature and pressure sensations from outside the teeth through a network of tiny passageways (tubules) in the dentin. Enamel muffles these sensations before traveling the tubules, which prevents overstimulation of the nerves.
This careful balance can be disrupted, however, if the enamel becomes eroded by acid from foods or beverages, or as a byproduct of bacteria. This exposes the underlying dentin to the full brunt of outward sensations, which can then impact the nerves and cause them to overreact.
This hyper-sensitivity can also occur around the tooth roots, but for a different reason. Because the gums primarily protect this area rather than enamel, the roots can become hyper-sensitive if they lose gum coverage, a condition known as gum recession caused mainly by gum disease or over-aggressive hygiene.
Besides using dental products that block nerve sensation, reducing sensitivity largely depends on addressing the underlying cause. If gum disease, the focus is on removing plaque, a bacterial film on dental surfaces that causes and sustains the disease. Stopping an infection allows the gums to heal and hopefully regain their original teeth coverage. More advanced cases, though, may require grafting surgery to foster gum regeneration.
If the cause is enamel erosion or other results of decay or trauma, we can utilize a number of treatments depending on the extent of tooth damage including cavity filling, root canal therapy or crowning. As a last resort, we may need to remove a tooth that's beyond reasonable repair.
If you've begun to experience sensitive teeth, it's important that you see us as soon as possible. The earlier we can diagnose the cause, the less invasive we can be with treatments to ease or even stop this most unpleasant experience.
