Tooth decay is one of two dental diseases most responsible for tooth loss (gum disease being the other). In the absence of treatment, what starts as a hole or cavity in a tooth's outer layers can steadily advance toward its interior.
Most people associate cavities with the crown, the part of a tooth you can see. But cavities can also occur in a tooth's roots, especially with older adults. Root cavities pose two distinct difficulties: They can lead to more rapid decay spread than crown cavities within a tooth; and they're harder to detect.
Tooth roots are ordinarily covered by the gums, which protects them from bacterial plaque, the main cause for decay. But roots can become exposed due to receding gums, a common problem with seniors who are more susceptible to gum disease.
Unlike the enamel-covered crowns, tooth roots depend on gum coverage for protection against bacteria and the acid they produce. Without this coverage, the only thing standing between tooth decay and the roots is a thin material called cementum.
If decay does enter a tooth's interior, saving it often requires a root canal treatment to remove decayed tissue in the inner pulp and root canals, and then replacing it with a filling. But if we're able to discover a root cavity in its early stages, we may be able to fill it like a crown cavity.
The best strategy, though, is to prevent root cavities from forming. This starts with a dedicated daily regimen of brushing and flossing to remove dental plaque. If you're at high risk for root cavities, we may also recommend antibacterial mouthrinses and other aids.
Regular dental visits are also a must: a minimum of twice-a-year dental cleanings to remove stubborn plaque and calculus (hardened plaque) deposits. For added protection against root cavities, we can also apply fluoride varnish to strengthen teeth. And regular visits are the best way to detect any cavity in its early stages when treatment is less invasive.
A heightened risk of dental problems like root cavities are a part of the aging process. But partnering together, we can lower that risk and increase the longevity of your teeth.

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.
Each year thousands of people develop sinus infections from various causes. But there's one cause for sinusitis that might surprise you—tooth decay.
Tooth decay begins when the acid produced by oral bacteria erodes a tooth's enamel protection to create a small hole or cavity. Left untreated, the infection can move into the inner pulp of the tooth and tiny passageways leading to the roots called root canals. The decay can then infect and break down the structure of the supporting jawbone.
This could affect the sinus cavities, hollow air-filled spaces in the upper portion of the face. The maxillary sinus in particular sits behind the cheek bones just above the upper jaw. Tooth roots, particularly in back teeth, can extend quite near or even poke through the floor of the maxillary sinus.
If decay affects these roots, the bone beneath this floor may begin to break down and allow the bacterial infection to enter the sinus. We call this particular kind of sinus infection maxillary sinusitis of endodontic origin (MSEO), "endodontic" referring to the interior structure of teeth.
While advanced decay can show symptoms like pain or sensitivity with certain hot or cold foods, it's also possible to have it and not know it directly. But a recurring sinus infection could be an indirect indication that the root of your suffering is a deeply decayed tooth. Treating the sinus infection with antibiotics won't cure this underlying dental problem. For that you'll need to see a dentist or an endodontist, a specialist for interior tooth issues.
The most common way to treat deep tooth decay is with root canal therapy. In this procedure, the dentist enters the decayed tooth's pulp (nerve chamber) and root canals and removes the diseased tissue. They will then fill the empty pulp and root canals with a special filling and seal the tooth to prevent future infection. The procedure stops the infection and saves the tooth—and if you have MSEO, it eliminates the cause of the sinus infection.
So, if you're suffering from chronic sinus infections, you might talk with your dentist about the possibility of a tooth infection. A thorough examination might reveal a decayed tooth in need of treatment.
A root canal treatment is a common procedure performed by dentists and endodontists (specialists for inner tooth problems). If you're about to undergo this tooth-saving procedure, here's what you need to know.
The goal of a root canal treatment is to stop tooth decay within a tooth's interior and minimize any damage to the tooth and underlying bone. This is done by accessing the tooth's pulp and root canals (tiny passageways traveling through the tooth roots to the bone) by drilling into the biting surface of a back tooth or the "tongue" side of a front tooth.
First, though, we numb the tooth and surrounding area with local anesthesia so you won't feel any pain during the procedure. We'll also place a small sheet of vinyl or rubber called a dental dam that isolates the affected tooth from other teeth to minimize the spread of infection.
After gaining access inside the tooth we use special instruments to remove all of the diseased tissue, often with the help of a dental microscope to view the interior of tiny root canals. Once the pulp and root canals have been cleared, we'll flush the empty spaces with an antibacterial solution.
After any required reshaping, we'll fill the pulp chamber and root canals with a special filling called gutta-percha. This rubberlike, biocompatible substance conforms easily to the shape of these inner tooth structures. The filling preserves the tooth from future infection, with the added protection of adhesive cement to seal it in.
Afterward, you may have a few days of soreness that's often manageable with mild pain relievers. You'll return for a follow-up visit and possibly a more permanent filling for the access hole. It's also likely you'll receive a permanent crown for the tooth to restore it and further protect it from future fracture.
Without this vital treatment, you could very well lose your tooth to the ravages of decay. The time and any minor discomfort you may experience are well worth the outcome.
