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 best known as restorations for single missing teeth. But there’s more to them than that—they can also be used to support and secure removable dentures or fixed bridges.
That’s because a dental implant is actually a root replacement. A threaded titanium post is inserted directly into the jawbone where, over time, bone cells grow and adhere to it. This accumulated bone growth gives the implant its signature durability and contributes to its long-term success rate (95%-plus after ten years). It can support a single attached crown, or serve as an attachment point for a dental bridge or a connector for a removable denture.
The method and design of implants differentiates it from other restoration options. And there’s one other difference—implants require a minor surgical procedure to insert them into the jawbone.
While this might give you pause, implant surgery is no more complicated than a surgical tooth extraction. In most cases we can perform the procedure using local anesthesia (you’ll be awake the entire time) coupled with sedatives (if you have bouts of anxiety) to help you relax.
We first access the bone through small incisions in the gums and then create a small channel or hole in it. A surgical guide that fits over the teeth may be used to help pinpoint the exact location for the implant.
We then use a drilling sequence to progressively increase the size of the channel until it matches the implant size and shape. We’re then ready to insert the implant, which we remove at this time from its sterile packaging. We may then take a few x-rays to ensure the implant is in the right position, followed by closing the gums with sutures.
There may be a little discomfort for that day, but most patients can manage it with over-the-counter pain relievers like aspirin or ibuprofen. It’s what goes on over the next few weeks that’s of prime importance as the bone grows and adheres to the implant. Once they’re fully integrated, we’re ready to move to the next step of affixing your crown, bridge or denture to gain what you’ve waited so long for—your new implant-supported smile.

Durable as well as life-like, dental implants are by far the preferred method for replacing missing teeth. But they can be costly and, although not as much, so can traditional bridgework. Is there an effective but more affordable means to replace a few missing teeth?
There is: a removable partial denture (RPD). In fact, RPDs have always been the less expensive alternative to bridgework and implants. Today's RPDs are usually made of vitallium, a strong but lightweight metal alloy. Because of the metal's characteristics, we can create an appliance that precisely matches the contours of your gums, is thin and hardly noticeable. We anchor prosthetic (false) teeth made of porcelain, resins or plastics in acrylic or nylon that resembles gum tissue.
The most important aspect of an RPD is to design it to produce the least amount of movement in your mouth as you eat or speak. A good design will minimize pressure on both the underlying bone (which can accelerate bone loss) and on the remaining teeth that support the RPD. Although a little more costly, it may be advantageous to use a dental implant to stabilize a lower partial denture when no end tooth is available for support.
To get the most out of your RPD — and to prevent dental disease — it's important for you to practice diligent daily hygiene. RPD attachments can make remaining teeth more susceptible to plaque accumulation, a thin film of bacteria and food particles that can cause tooth decay and periodontal (gum) disease. To avoid this you should remove the RPD and thoroughly brush and floss your remaining teeth. You should clean the RPD every day with recommended cleansers. You should also take it out at night while you sleep to discourage further bacterial or fungal growth.
Besides daily care for your RPD and natural teeth, be sure to visit us for cleanings and checkups at least twice a year. Taking care of both your appliance and your mouth will help ensure your RPD serves you for many years to come.
