It's normal to have occasional mouth dryness—that "cotton mouth" feeling when you first wake up or after eating a spicy meal. It soon dissipates, though, leaving you no worse for wear other than the memory of an unpleasant sensation.
For some, though, the unpleasant sensation becomes a chronic condition known as xerostomia, in which their mouth feels dry most of the time. And, it can have far-reaching consequences beyond a mere irritation if not treated.
Among the numerous causes for xerostomia, the most common appears to be over-the-counter and prescription medication. An estimated five hundred medications have dry mouth as a potential side-effect, from antihistamines to antidepressants. And because people over 65 are more likely to take medications, they also have a high occurrence of xerostomia.
A person with certain systemic diseases like Parkinson's Disease or undergoing radiation or chemotherapy for cancers of the head and neck may also encounter dry mouth. For example, an autoimmune disease called Sjögren's syndrome, primarily affecting postmenopausal women, can dry out the mouth's mucous membranes.
Chronic dry mouth isn't normal, and often a sign of a health problem that should be examined. And it can lead to more problems with your oral health. Because dry mouth is most likely a reduction in saliva, which helps buffer decay-causing acid and provides antibodies to fight bacteria, having less of this vital fluid can increase your risk for both tooth decay and gum disease.
So, what can you do if you're plagued by persistent dry mouth? If you suspect your medications may be a factor, talk with your doctor about whether one of them may be the underlying cause for your symptoms. You may be able to switch to an alternate medication without dry mouth side-effects.
You can also increase your water intake during the day, including drinking more before and after taking medication. And there are a number of products like the artificial sweetener xylitol found in gums and candies that can boost saliva. Your dentist may also be able to recommend products that increase saliva.
Above all, be sure you keep up daily brushing and flossing, as well as regular dental cleanings. Taking care of chronic dry mouth could help you avoid dental problems later.

Tooth loss is often the unfortunate conclusion to a case of untreated periodontal (gum) disease—incentive enough to try either to prevent it or aggressively treat an infection should it occur. In either case, the objective is the same: to remove all plaque from dental surfaces.
Dental plaque (and its hardened form, tartar) is a thin buildup of bacteria and food particles on tooth surfaces. It's a ready food source for sustaining the bacteria that cause gum disease. Removing it can prevent an infection or “starve” one that has already begun.
Your first line of prevention is brushing and flossing your teeth daily to remove any accumulated plaque. Next in line are dental cleanings at least twice a year: This removes plaque and tartar that may have survived your daily hygiene.
Plaque removal is also necessary to stop an infection should it occur. Think of it as a more intense dental cleaning: We use many of the same tools and techniques, including scalers (or curettes) or ultrasonic devices to loosen plaque that is then flushed away. But we must often go deeper, to find and remove plaque deposits below the gums and around tooth roots.
This can be challenging, especially if the infection has already caused damage to these areas. For example, the junctures where tooth roots separate from the main body of the tooth, called furcations, are especially vulnerable to disease.
The results of infection around furcations (known as furcation involvements or furcation invasions) can weaken the tooth's stability. These involvements can begin as a slight groove and ultimately progress to an actual hole that passes from one end to the other (“through and through”).
To stop or attempt to reverse this damage, we must access the roots, sometimes surgically. Once we reach the area, we must remove any plaque deposits and try to stimulate regrowth of gum tissue and attachments around the tooth, as well as new bone to fill in the damage caused by the furcation involvement.
Extensive and aggressive treatment when a furcation involvement occurs—and the earlier, the better—can help save an affected tooth. But the best strategy is preventing gum disease altogether with dedicated oral hygiene and regular dental visits.

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.
