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.

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.

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.
