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.

Dental implants are widely considered by both dentists and patients as the premier choice for replacing missing teeth. Unfortunately, implants aren’t the appropriate choice for teenagers with missing teeth.
That’s because their jaws won’t fully finish most of their growth and development until early adulthood. An implant placed too early could become misaligned as the jaw matures. The best approach for a teenager is a temporary restoration until they’re old enough for an implant.
There are a couple of good options. One is a removable partial denture (RPD), prosthetic (false) teeth set in an acrylic base that mimics gum tissue at the locations of the missing teeth. RPDs, which stay in place by way of metal clips that fit over other teeth, are easy to wear and maintain.
On the downside, an RPD can break if you bite into something too hard. They can lose their fit and may need to be replaced with a new one. And, some teens aren’t quite keen on wearing a “denture.”
Another option is a bonded or Maryland bridge, a kind of fixed bridge. We bond dental material to the back of a prosthetic tooth with portions of the material extending out from either side of it.Â We then bond these extending tabs to the back of the teeth on either side of the prosthetic tooth to hold it in place. Unlike traditional bridges, we can eventually remove it without any permanent alterations to the teeth it’s attached to.
Before we undertake a bonded bridge, though, we must make sure the gums and bone of the surrounding teeth are free from periodontal (gum) disease and are healthy and strong enough to support the bridge. We also need to be sure the patient doesn’t have a deep bite or a teeth grinding habit, which could cause the teeth to make contact with the tabs and break them.
The patient also needs the maturity to responsibly perform diligent oral hygiene: this type of bridge has a tendency to build up disease-causing plaque, so brushing twice and flossing once every day is critical. Not doing so increases the risk of tooth decay or periodontal (gum) disease, which could complicate a future implant.
We can discuss these options after a thorough dental examination of your teenager. Either way, we’ll be able to restore your teen’s smile until we can undertake a more permanent restoration.
