When your mouth is dry, you know it: that sticky, uncomfortable feeling when you first wake up or when you're thirsty. Fortunately, it usually goes away after you eat or drink. But what if your mouth felt like that all the time? Then, it's no longer an irritation—chronic dry mouth could also increase your risk of dental disease.
Chronic dry mouth occurs because of inadequate saliva flow. Saliva plays an important role in preventing dental disease because it neutralizes acid, which can cause the mineral content in tooth enamel to break down and lead to tooth decay. The mouth becomes more acidic right after eating, but saliva can restore its normal pH levels in about an hour—as well as some of the enamel's lost mineral content. Without saliva, your tooth enamel is at greater risk from acid.
While a number of things can potentially interfere with normal saliva production, medication is the most common. More than 500 prescription drugs, including many antihistamines, diuretics or antidepressants, can cause dry mouth. Cancer radiation or chemotherapy treatment and certain metabolic conditions like diabetes or Parkinson's disease can also increase symptoms.
If you are experiencing unusual dry mouth symptoms, see your dentist first for a full examination. Your dentist can measure your saliva flow, check your prescriptions and medical history, and examine your salivary glands for abnormalities. With this more accurate picture of your condition, they can help direct you to the most effective remedies and treatments for the cause.
If medication is the problem, you can talk to your doctor about alternative prescriptions that have a lesser effect on saliva flow. You can also drink more water before and after taking oral medication and throughout the day to help lubricate your mouth. Chewing gums or mints with xylitol, a natural alcohol sugar, can also help: xylitol helps reduce the mouth's bacterial levels, as well as stimulate saliva flow.
Easing your dry mouth symptoms can make your life more pleasant. More importantly, it can reduce your risk of future dental problems caused by a lack of saliva.

We’ve come a long way since the early 1980s when we first identified the HIV virus. Although approximately 35 million people worldwide (including a million Americans) now have the virus, many are living relatively long and normal lives thanks to advanced antiretroviral drugs.
Still, HIV patients must remain vigilant about their health, especially their oral health. In fact, problems with the teeth, gums and other oral structures could be a sign the virus has or is moving into the full disease stage, acquired immunodeficiency syndrome (AIDS). That’s why you or a loved one with the virus should maintain regular dental checkups or see your dentist when you notice any oral abnormalities.
One of the most common conditions among HIV-positive patients is a fungal infection called candidiasis (or “thrush”). It may appear first as deep cracks at the corners of the mouth and then appear on the tongue and roof of the mouth as red lesions. The infection may also cause creamy, white patches that leave a reddened or bleeding surface when wiped.
HIV-positive patients may also suffer from reduced salivary flow. Because saliva helps neutralize excess mouth acid after we eat as well as limit bacterial growth, its absence significantly increases the risk of dental disease. One of the most prominent for HIV-positive patients is periodontal (gum) disease, a bacterial infection normally caused by dental plaque.
While gum disease is prevalent among people in general, one particular form is of grave concern to HIV-positive patients. Necrotizing ulcerative periodontitis (NUP) is characterized by spontaneous gum bleeding, ulcerations and a foul odor. The disease itself can cause loosening and eventually loss of teeth, but it’s also notable as a sign of a patient’s deteriorating immune system. The patient should not only undergo dental treatment (including antibiotics), but also see their primary care physician for updates in treating and managing their overall symptoms.
Above all, HIV-positive patients must be extra diligent about oral hygiene, including daily brushing and flossing. Your dentist may also recommend other measures like saliva stimulators or chlorhexidine mouthrinses to reduce the growth of disease-causing bacteria. Together, you should be able to reduce the effects of HIV-induced teeth and gum problems for a healthier mouth and better quality of life.

Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.

People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

Athletes in contact sports are at significant risk for traumatic injury to their teeth and mouth. It’s estimated 600,000 emergency room visits each year involve a sports-related dental injury.
Athletic mouthguards have become the premier safeguard against sports-related oral injuries. First worn by professional boxers in the 1920s, mouthguards are now required for use by various sports associations and leagues — from amateur youth to professional — for a number of sports. The National Collegiate Athletic Association (NCAA), for example, requires their use during play for hockey, lacrosse, field hockey and football. The American Dental Association recommends mouthguards for 29 sports or exercise activities.
But do mouthguards actually prevent injury? To answer that question in a scientific manner, the Journal of Sports Medicine published an evidence-based report in 2007 on mouthguard effectiveness for preventing or reducing the severity of oral-facial injuries and concussions. While the report objectively analyzed many of the problems and issues associated with mouthguards (like materials, design and durability), it concluded the risk of an oral-facial injury was nearly two times greater without the wearing of a mouthguard.
That being said, most dentists and other professionals in sports safety would advise not all mouthguards are alike. The stock, “off the shelf” mouthguard found in many retail stores with limited size offerings is the least expensive, but also least protective, of mouthguard types. Mouth-formed or “boil-and-bite” protectors, which are softened in boiling water and then bit down on by the player to form the fit, are better than the stock version — however, they often don’t cover all of the player’s back teeth.
The best option is a custom-designed guard made by a dentist for the individual patient. Although relatively expensive (costs range in the hundreds, compared with $25 or less for a stock guard), they provide the highest recognized level of mouth protection.
The bottom line: a mouthguard is a must-wear part of any uniform for any sport that involves contact or high velocity objects of play. If you or a family member is a contact sport athlete, it’s essential you protect your teeth and mouth with a custom-fit, high quality mouthguard.
