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.

Human beings have known for millennia the importance of keeping teeth clean. Although we've only come to more fully understand dental plaque's role in dental disease in the last century, our ancestors seemed to know instinctively this gritty biofilm on teeth had to go.
People from the past once used a variety of substances like ground oyster shells or leftover fire ashes to remove plaque from their teeth. Today, most of the world has replaced these substances with toothpaste, a mainstay of daily oral hygiene.
So, why is toothpaste better than other substances used in the ancient past? Besides the many other ingredients found in the typical tube of toothpaste, here are the top 3 that make it the ultimate tooth cleaner.
Abrasives. While your toothbrush does most of the mechanical work loosening plaque, toothpaste has ingredients called abrasives that give an added boost to your brushing action. The ideal abrasive is strong enough to remove plaque, but not enough to damage tooth enamel. If you look at your toothpaste's ingredient list, you'll probably see an abrasive like hydrated silica (made from sand), hydrated alumina, calcium carbonate or dicalcium phosphates.
Detergents. Your toothpaste's foaming action is a sign of a detergent, which helps loosen and break down non-soluble (not dissolvable with plain water) food substances. While similar to what you may use to wash your clothes or dishes, toothpaste detergents are much milder, the most common being sodium lauryl sulfate found in many cosmetic items. If you have frequent canker sores, though, sodium lauryl sulfate can cause irritation, so look for a toothpaste with a different detergent.
Fluoride. The enamel strengthening power of fluoride was one of the greatest discoveries in dental care history. Although not all toothpastes contain it, choosing one with fluoride can improve your enamel health and help protect you from tooth decay.
These and other ingredients like binders, preservatives and flavorings, all go in to make toothpaste the teeth-cleaning, disease-fighting product we've all come to depend upon. Used as part of daily oral hygiene, toothpaste can help brighten and freshen your smile, and keep your teeth and gums healthy.

After your son or daughter's dental exam, you expect to hear about cavities, poor bites or other dental problems. But your dentist might suggest a different kind of problem you didn't expect—an eating disorder.
It's not a fluke occurrence—a dental exam is a common way bulimia nervosa or anorexia nervosa come to light. That's because the teeth are often damaged by the behaviors of a patient with an eating disorder.
Most of this damage occurs because of purging, the practice of induced vomiting after eating. During vomiting stomach acid can enter the mouth and "wash" against the back of the teeth. After repeated episodes, the acid dissolves the mineral content of tooth enamel and causes it to erode. There's also a tell-tale pattern with eating disorders: because the tongue partially shields the back of the lower teeth while purging, the lower teeth may show less enamel erosion than the upper.
Hygiene practices, both negligent and too aggressive, can accelerate erosion. Anorexics often neglect basic grooming and hygiene like brushing and flossing, which increases the likelihood of dental disease. Bulimia patients, on the other hand, can be fastidious about their hygiene. They're more likely to brush immediately after purging, which can cause tiny bits of the enamel immediately softened by the acid wash to slough off.
In dealing with a family member's eating disorder, you should consider both a short and long-term approach to protect their dental health. In the sort-term the goal is to treat the current damage and minimize the extent of any future harm. In that regard, encourage them to rinse with water (mixed optionally with baking soda to help neutralize acid) after purging, and wait an hour before brushing. This will give saliva in the mouth a chance to fully neutralize any remaining acid. Your dentist may also recommend a sodium fluoride mouth rinse to help strengthen their tooth enamel.
For the long-term, your goal should be to help your loved one overcome this potentially life-threatening condition through counseling and therapy.

Taking steps to treat an eating disorder could save not only your loved one's dental health, but also their life.

There are two basic facts about tooth decay: 1) next to the common cold, it’s the world’s most prevalent infectious disease; and 2) with modern dentistry, it’s preventable.
Getting from Fact 1 to Fact 2 requires the daily hygiene habits of brushing and flossing. You probably learned these tasks when you could barely peer over the bathroom sink; but the real question is: are you getting the most benefit from your efforts? It’s not merely doing them, but doing them the right way.
For example, bearing down on your teeth and brushing vigorously isn’t just unhelpful, it’s damaging. Instead, you should hold your brush with perhaps just two fingers at a 45-degree angle relative to your gum line and “gently” scrub with short circular or “wiggly” strokes. Continue this action around each arch brushing all tooth surfaces, which should take about two minutes.
Your toothbrush itself is also important: most people (unless otherwise directed by their dentist) should use a multi-tufted brush with soft bristles. If you brush with the proper pressure it should last 4 to 6 months before replacing it. You should also replace it if the bristles become worn or splayed.
Flossing once a day is important for removing the plaque between teeth your toothbrush bristles can’t reach. The best technique is to form a “C” with the floss that wraps around each tooth and move it up and down gently three or four times until you hear a squeaky clean sound on both sides of the tooth.
The ultimate test of your efforts comes during your regular dental checkups. You can get a check now, though, on how you’re doing by using your tongue to feel your teeth at the gum line. If they feel smooth and slick, you’re probably doing a good job of plaque removal; but if they feel a bit rough and gritty, you’re missing some of the plaque and need to be more thorough when brushing. You can also use floss by running it up and down the tooth surface — if it squeaks, they’re clean!
Your particular dental condition may require specific treatment or the use of other dental products like antibacterial mouthrinses. But learning and practicing proper brushing and flossing is key to keeping teeth and gums healthy and disease-free.
As a regular part of your daily hygiene you may be using a mouthrinse — or “mouthwash” — mainly to keep your mouth feeling fresh and clean. Some mouthrinses, though, do more than give you fresher breath.
While there are countless mouthrinses available, we can place all of them into two broad categories: cosmetic and therapeutic. The first refresh your mouth and breath, usually with a mentholated or minty taste and smell that masks unpleasant odors. How well they work is mainly subjective: if you feel better after using them, they’ve done their job.
Therapeutic rinses have a different role, intended to improve oral health in some way. We can divide these into anti-cariogenic (decay prevention) or anti-bacterial rinses. You can find fluoride-based anti-cariogenic rinses over-the-counter in retail or drug stores, usually containing about .05% sodium fluoride per volume. Numerous studies have shown these rinses highly effective in preventing tooth decay when used with daily brushing and flossing.
Likewise, over-the-counter antibacterial rinses have proven somewhat effective in reducing bacteria that leads to dental disease. Formulated usually with triclosan, sanguinaria extract, zinc or essential oils, they can also help reduce the incidence of gingivitis (inflammation of the gums), but only if used in conjunction with brushing and flossing.
Perhaps, though, the most widely studied and substantiated therapeutic mouthrinse is chlorhexidine, a prescription-only rinse. Chlorhexidine inhibits the formation of bacterial plaque on tooth surfaces, the main trigger for both tooth decay and periodontal (gum) disease. It’s often used as a post-surgery rinse when brushing and flossing may not be possible, but dentists will often prescribe it for patients who have a high propensity for dental disease.
Using a mouthrinse depends on your current oral health and personal preferences. Therapeutically, most people gain some added tooth strength protection from using a fluoride rinse in their daily hygiene. If fresh breath and the way your mouth feels are important to you, you should consider such a rinse that also has a pleasant taste and effect for you. We can further discuss with you whether a different type of rinse, or a prescription-strength formula, might be best for your particular needs.
