In addition to the usual tooth and gum problems, dentists also see patients with soft tissue infections in and around the mouth. One of the more common of these is the irritation or "cracking" of the corners of the mouth.
Formally known as angular cheilitis (or perleche, a French word, meaning "to lick"), cracked mouth corners are localized irritations made worse by saliva accumulation or an accompanying yeast infection. They're prominent among children and young adults who drool during sleep or while wearing orthodontic braces.
Older adults can also develop cracked mouth corners because of deep wrinkle lines around the mouth ("marionette lines") or tissue irritation from wearing dentures. Teeth loss, especially in the back of the jaws, can weaken facial support leading to collapse of the bite, which can contribute to angular cheilitis.
The condition can cause anything from minor discomfort at the mouth corners to a yeast infection that spreads throughout the mouth and throat. Whatever the symptoms, treatment usually begins with antifungal medication in the form of a mouthrinse or a topical ointment. The dentist may also prescribe a steroid ointment like zinc oxide paste to control inflammation and serve as a barrier against infection.
If the infection has spread beyond the mouth corners, patients may also need to use an antibacterial mouthrinse (usually chlorhexidine) to clear up the infection and help prevent a relapse. Besides cleaning their appliances with chlorhexidine, denture wearers with angular cheilitis should also take their dentures out at night to reduce the chances of a reoccurrence.
Along the same vein, patients who contend with frequent cracked mouth corners and who have missing teeth should have those teeth replaced by some form of restoration. If that involves dentures, it's important to maintain a good fit with them to reduce the chances of tissue irritation. And patients with deep wrinkle lines around their mouth may be able to lessen them through dermatological treatment.
Even though cracked mouth corners rarely pose a major health problem, the discomfort they cause can be a drag on your daily life and activities. Remember that you don't have to suffer—a visit to your dentist could start you on your journey toward relief from this irritating problem.

Root canals often get a bum rap. Although the procedure saves millions of teeth every year, it's often erroneously portrayed as an unpleasant experience. And if that wasn't enough, a long-discredited medical theory has found new life on the internet asserting root canals are a health danger.
First off, root canals play an immensely important role in treating teeth with advanced decay. If not promptly treated, a cavity can turn into a major infection of the interior tooth pulp and root canals, and ultimately the supporting bone. Teeth with this level of decay are not long for this world.
A root canal treatment stops this disease process in its tracks. After numbing the tooth and surrounding gums, we drill a small hole into the tooth's interior and then remove all of the infected tissue within the pulp and root canals. After disinfecting these areas, we fill them with a rubber-like substance called gutta percha.
After sealing off the access hole—and later capping the tooth with a life-like crown—the tooth is secure from further decay. And, by the way, the procedure doesn't hurt, thanks to local anesthesia. If anything, any pain caused by the decay attacking the tooth's nerves has now been alleviated.
So, what about the idea floating on the Web that root canals are dangerous? The "root" for this conjecture is a theory by Weston Price, an early 20th Century dentist, that leaving a "dead" body part in the body leads to various health problems (including cancer). That would include a root-canaled tooth, which has had the living tissue in the pulp removed.
There's just one problem—Weston's theory was fully investigated in the 1950s and overwhelmingly discredited. The supposed cancer threat was also reviewed in a 2013 study, which found no link between root canals and increased cancer risk. In fact, dental patients who had undergone several root canals had a diminished risk.
Like all other health procedures, root canals have some risks of complication. But those complications are far from life-threatening—it's tooth-saving benefits are often worth the risk. So, fear not if your dentist says you need a root canal. It won't hurt and it won't endanger your health—and it could save your tooth.

Tooth loss is often the unfortunate conclusion to a case of untreated periodontal (gum) disease—incentive enough to try either to prevent it or aggressively treat an infection should it occur. In either case, the objective is the same: to remove all plaque from dental surfaces.
Dental plaque (and its hardened form, tartar) is a thin buildup of bacteria and food particles on tooth surfaces. It's a ready food source for sustaining the bacteria that cause gum disease. Removing it can prevent an infection or “starve” one that has already begun.
Your first line of prevention is brushing and flossing your teeth daily to remove any accumulated plaque. Next in line are dental cleanings at least twice a year: This removes plaque and tartar that may have survived your daily hygiene.
Plaque removal is also necessary to stop an infection should it occur. Think of it as a more intense dental cleaning: We use many of the same tools and techniques, including scalers (or curettes) or ultrasonic devices to loosen plaque that is then flushed away. But we must often go deeper, to find and remove plaque deposits below the gums and around tooth roots.
This can be challenging, especially if the infection has already caused damage to these areas. For example, the junctures where tooth roots separate from the main body of the tooth, called furcations, are especially vulnerable to disease.
The results of infection around furcations (known as furcation involvements or furcation invasions) can weaken the tooth's stability. These involvements can begin as a slight groove and ultimately progress to an actual hole that passes from one end to the other (“through and through”).
To stop or attempt to reverse this damage, we must access the roots, sometimes surgically. Once we reach the area, we must remove any plaque deposits and try to stimulate regrowth of gum tissue and attachments around the tooth, as well as new bone to fill in the damage caused by the furcation involvement.
Extensive and aggressive treatment when a furcation involvement occurs—and the earlier, the better—can help save an affected tooth. But the best strategy is preventing gum disease altogether with dedicated oral hygiene and regular dental visits.
