TreatingDryMouthisImportantforMaintainingGoodOralHealth

Saliva is a true workhorse among bodily fluids — it breaks down food for digestion, keeps harmful bacteria in check and neutralizes acid that is destructive to tooth surfaces. So when saliva flow is chronically diminished, it’s more serious than the uncomfortable feeling of “dry mouth” — it can have a detrimental effect on your overall health.

It’s normal to experience temporary mouth dryness: in the morning (because saliva flow slows during sleep), when we’re under stress, or after smoking or consuming certain foods and beverages like onions or coffee. But chronic dry mouth (“xerostomia”) is different — the mouth remains dry for extended periods, leading to problems like tooth decay caused by inadequate acid neutralization.

Medications are one of the most common causes for xerostomia. According to the Surgeon General, there are over 500 medications — both prescription and over-the-counter — that can cause it, including antihistamines, diuretics and antidepressants. Radiation or chemotherapy used for cancer treatment may also cause dry mouth, sometimes permanently. There are also systemic conditions that affect saliva flow like diabetes, Parkinson’s disease, cystic fibrosis, and many autoimmune diseases.

Treating chronic dry mouth will of course depend on the underlying cause. If drug-related the first approach should be to find a substitute medication that won’t as readily cause reduced saliva flow. If that’s not possible, then it’s helpful to drink more water when taking the medication (a few sips before and a full glass afterward). You can also cut back on caffeinated, acidic or sugary foods and drinks as well as alcohol, and refrain from tobacco use.

A saliva stimulant might also help. Besides prescription medication, there are other products like xylitol, a natural alcohol sugar found in chewing gum, toothpaste or rinses, that help increase saliva flow — and xylitol also inhibits the growth of decay-causing bacteria.

The most important thing for chronic dry mouth is maintaining consistent daily hygiene through brushing and flossing and regular dental cleanings and checkups. Helping to increase your saliva flow and making every effort to prevent dental disease will help keep this condition from harming your teeth and gums.

HowEffectiveisYourOralHygieneFindOutwithaPlaqueDisclosingAgent

Brushing and flossing every day are important for preventing dental disease. The object is to remove as much bacterial plaque, the thin biofilm most responsible for disease, from your teeth and gums as possible.

But how do you know your hygiene efforts are that effective? You can of course do the “tongue test” â?? feel your teeth with your tongue after brushing and flossing and see if they feel smooth and “squeaky” clean. We can also give you a “report card” at your regular cleaning appointment. There is, however, a more precise way you can find out at home by using a plaque disclosing agent.

A plaque disclosing agent is a formulation that when applied to the teeth will temporarily dye any bacterial plaque present a distinct color. While dental hygienists occasionally apply them, they’re also available over the counter for use at home. They’re usually found in a solution, tablet or swab form in various flavors.

To use the product you first brush and floss, then swish the disclosing liquid around in your mouth for about 30 seconds before spitting it out (or chew the tablet or apply the swab as directed). The agent will react with any remaining plaque and dye it a bright color. There are even two-tone agents available that can differentiate between old and new plaque and dye them different colors.

Examining your teeth in a mirror will give you a good idea where you need to concentrate your attention when brushing and flossing. If, for example, you see dyed plaque more along the gum line and less in other places, then that’s where you should focus your hygiene efforts.

While the dye will eventually wear off on its own, you should take the opportunity to brush and floss again to remove any remaining dyed plaque. Not only does this provide a more thorough cleaning at that moment, you’ll also get a better sense of how “thoroughness” feels for future brushing and flossing.

It’s always good to know how well you’re doing with your dental hygiene efforts. A plaque disclosing agent can give you just the right feedback to help you improve.
