Root canal treatments are an essential part of dental care — countless teeth with deep decay would be lost each year without it. Now, this traditional dental care procedure is advancing to a new level of precision through lasers.
Root canal treatments have a simple goal: access a tooth's infected pulp and root canals, clean out the infected tissue and fill the empty pulp chamber and canals with a special filling. Once filled, the access is sealed and a porcelain crown later placed for additional protection against re-infection.
In the traditional procedure, we perform these steps manually with a dental drill and hand instruments. We may also need to remove a good portion of tooth structure, both healthy and infected tissue. A laser, on the other hand, is a highly focused beam of light with the ability to interact with healthy and infected tissues differently: destroying infected tissue while having no effect on nearby healthy tissue. The end result: we may be able to remove less healthy tissue with lasers than with the conventional procedure.
Lasers are also helpful with softening and precisely molding the filling material within each canal's particular shape. And, early reports seem to indicate a higher degree of comfort for patients (less drill noise and need for anesthesia), less bleeding and faster recovery times than the conventional approach.
But as a tool for root canal treatments, lasers do have a couple of disadvantages. While light travels in a straight line, root canals are rarely straight — conventional instruments with curved designs usually accommodate odd canal shapes better than a laser. Lasers can also raise temperatures within a tooth that can damage healthy tissue, both within the pulp and outward into the dentin.
Still, lasers for root canal treatments appear promising with some dentists using a combination of lasers and manual techniques to garner benefits from both approaches. While you won't see lasers replacing the traditional root canal treatment anytime soon, the future looks bright for more efficient ways to treat deep tooth decay.
Perhaps you haven’t thought of it quite this way, but saliva is one of the true wonders of the human body. This unassuming fluid performs a variety of tasks to aid digestion and help protect your mouth from disease. And you hardly notice it — except when it’s not there.
That’s the case for millions of people in America who have a chronic condition called xerostomia or “dry mouth.” This happens when the salivary glands don’t secrete enough saliva, normally two to four pints daily.
Of course, we can experience mouth dryness when we first wake up (saliva flow ebbs while we sleep), feel stressed, use tobacco, or consume alcohol and certain foods like onions or spices. It becomes a problem, though, when periods of low saliva become chronic. Without its preventive capabilities, you’ll be at much higher risk for dental diseases like tooth decay or periodontal (gum) disease.
Chronic dry mouth can occur for various reasons: systemic diseases like cancer or autoimmune deficiencies can cause it, as well as radiation or chemotherapy treatments. One of the most common causes, though, is medication, both over-the-counter and prescription. The surgeon general identifies over 500 known drugs that may inhibit saliva production, including some antihistamines, diuretics and antidepressants. It’s often why older people who take more medications than younger people suffer more as a population from dry mouth.
Because of its long-term health effects, it’s important to try to boost saliva flow. If your mouth is consistently dry, try to drink more fluids during the day. If you suspect your medication, see if your physician can prescribe a different drug. It also helps to drink a little water before and after taking oral medication.
We may also recommend medication or other substances that stimulate saliva or temporarily substitute for it. Xylitol, a natural alcohol sugar that also inhibits bacterial growth, can help relieve dryness. You’ll often find it in gums or mints.
Chronic dry mouth is more than a minor irritation — it can lead to more serious conditions. In addition to these tips, be sure to also keep up your regular dental visits and maintain a daily schedule of oral hygiene to prevent dental disease.
