Although there are several potential problems people could encounter involving their teeth, gums or mouth, most fall into three basic categories. That's the finding of a recent survey conducted by the American Dental Association of more than 15,000 U.S. adults.
These categories are a triad of symptoms, each of which could arise from a variety of causes. If you're encountering any one of these, you should see your dentist as soon as possible.
Tooth pain. A toothache—or any form of pain from the mouth—could be sign of a number of possible issues. It could mean you have a decayed tooth, especially if the pain is sharp and localized. It could also indicate a gum abscess (accompanied by red and puffy gums), a sinus or ear infection, or inflammation of the jaw joints. The intensity, duration and location of the pain are all clues to its actual cause and what treatments it might require.
Biting difficulties. Does it hurt when you bite down? Among other things, you could have a loose tooth or one that's deeply decayed. The former could be the sign of advanced gum disease, which itself must be treated and the tooth stabilized (splinted) to other teeth. If the problem is advanced decay, you may need a root canal to remove diseased tissue from within the interior of the tooth, which is then filled and crowned to prevent re-infection.
Dry mouth. We're not talking about that "cotton mouth" feeling we all get now and then. This is a chronic condition known as xerostomia in which the mouth feels dry all the time. Xerostomia has several causes including smoking or treatments for cancer or other serious diseases. It might also be a medication you're taking, which has reduced your mouth's saliva production. Because dry mouth could lead to dental disease, you should take steps to relieve it.
Even if you're not having symptoms like these, there may still be something going on in your mouth that needs attention. That's why you should see your dentist on a regular basis, besides when you notice a problem, to keep your oral health in tip-top shape.
For several decades, dentists have been saving teeth from tooth decay following a few basic guidelines: 1) Identify decay as soon as possible; 2) Thoroughly remove decayed tooth structure; and 3) Fill any cavities. With millions of diseased teeth rescued, observing these simple steps have proven a rousing success.
But as with most things, even this successful protocol isn't perfect. For one, some healthy tissue gets removed along with the diseased portions. The average percentage of "collateral damage" has dropped over the years, but it still happens—and a reduction in healthy tissue can make a tooth less structurally sound.
Another drawback, at least from the patient's perspective, is the dental drill used for removing decay and preparing cavities for filling. Many people find drilling unpleasant, whether from its vibrations in the mouth or its high-pitched whine. The drill's burr head design also contributes to greater healthy tissue loss.
But those weaknesses have lessened over the last few years, thanks to innovations on a number of fronts.
Better risk management. Tooth decay doesn't occur out of thin air—it arises out of risk factors unique to an individual patient like personal hygiene, bacterial load, saliva production or even genetics. Taking the time to identify a patient's "tooth decay risk score" can lead to customized treatments and practices that can minimize the occurrence of decay.
Earlier detection. Like other aspects of dental health, the sooner we detect decay, the less damage it causes and the more successful our treatment. X-rays remain the workhorse for detecting decay, but now with improvements like digital film and better equipment. We're also using newer technologies like laser fluorescence and infrared technology that can "see" decay that might otherwise go undetected.
Less invasive treatment. The dental drill is now being used less with the advent of air abrasion technology. Air abrasion utilizes a concentrated spray of particles to remove diseased tooth structure more precisely than drilling. That means less healthy tissue loss—and a more pleasant (and quieter!) experience for the patient.
In effect, "less is more" could describe these improvements to traditional decay treatment. They and other methods promise healthier teeth and happier patients.

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.

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.

If you suffer frequent sinus infections, you might want to talk with your dentist about it. It could be your chronic sinus problems stem from a deeply decayed or infected tooth.
Sinuses are hollow, air-filled spaces in the front of the skull associated with nasal passages. The largest, the maxillary sinuses, are located just behind the cheekbones and above and to the rear of the upper jaw on either side of the face. These sinuses can become painfully congested when infected.
One possible cause for an infection in the maxillary sinus can occur in certain people whose upper back teeth (the molars and premolars) have roots that are close to or even protrude into the sinus. This is normally a minor anatomical feature, unless such a tooth becomes infected.
An infection in teeth with advancing decay or whose nerve tissue has died will eventually reach the root tip through tiny passageways called root canals. If the roots are close to or penetrating the maxillary sinus, the infection could move into the sinus. This is known as Maxillary Sinusitis of Endodontic Origin (MSEO).
A case of MSEO could potentially go on for years with occasional flare-ups of sinus congestion or post-nasal drip. Because of the nature of the infection within the sinus, the affected tooth itself may not show the normal signs of infection like sensitivity or pain. Doctors may attempt to treat the sinus infection with antibiotics, but because the actual source of the infection is within the tooth, this therapy is often ineffective.
If your doctor or dentist suspects MSEO, they may refer you to an endodontist, a specialist in root canals and interior tooth problems. With their advanced diagnostic capabilities, endodontists may have a better chance of accurately diagnosing and locating the source of a tooth-related infection.
As with any non-vital tooth, the likely treatment will be root canal therapy in which the infected tissue within the tooth is removed and the empty spaces filled to prevent future infection. For MSEO, the treatment not only preserves the tooth but may also relieve the infection within the sinus.
