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.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!
If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.
If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?
As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.
And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!
