If your teeth have a worn appearance, it's possible you have a habit you're not even aware of: clenching or grinding your teeth. Also called “bruxism,” this destructive action causes your top and bottom teeth to come together or scrape past each other with a force that's many times what is normal for biting and chewing.

So what's normal? This can be expressed in terms of pounds. An adult usually exerts a force of 13-23 pounds to bite or chew food. But we have the potential to generate as much as 230 pounds of force, or 10 times what's normal. A “parafunctional” force of this magnitude applied repeatedly is bound to stress your teeth and other areas of your oral system. Besides wearing away the enamel of your teeth — and maybe even some of the softer dentin layer underneath — you may experience muscle spasms or pain in your jaw joints. Serious cases of wear can lead to “bite collapse” in which your face actually changes shape as your cheeks and lips lose support. This can make you look prematurely aged.

What can be done? To prevent further wear, we can fabricate for you a thin, plastic mouthguard that will protect your teeth at night or during times of intense stress. We can also recommend ways to temporarily relieve the discomfort that your grinding/clenching habits can cause. Heat and/or anti-inflammatory medication, for example, can be helpful.

If your tooth wear is minor (raggedness along the biting edge of a tooth or teeth) you may not need any restorative work. However, if tooth wear has already caused changes to your teeth and bite that you find aesthetically or functionally unacceptable, we can restore lost tooth structure in a variety of ways. Veneers and crowns are two examples.

We tend to think of aspirin as a harmless medication. It is dispensed over the counter and is the most widely used OTC medication in the U.S. We take it without thinking we may be exposing ourselves to risks. But in certain situations aspirin can cause dangerous side effects.

What is aspirin, and how does it work?
The chemical name for aspirin is acetylsalicylic acid. It is used to reduce mild pain, inflammation and fever. When you take an aspirin, it blocks the formation of prostaglandins, substances your body creates that are associated with inflammation. Prostaglandins cause inflamed tissues to become red and swollen, but they also serve protective purposes, such as forming a barrier that protects the stomach from the acid it produces to digest your food. That's why long-term aspirin use can sometimes cause stomach bleeding and ulceration or other health problems.

Why do cardiac patients take aspirin?
Another effect of aspirin is to prevent blood platelets from clumping together. Blood platelets are structures in the blood, smaller than white or red blood cells, that aid clotting by sticking together at the site of an injury. This effect of aspirin can cause prolonged bleeding, but it may be beneficial to people who have cardiovascular (from cardio, meaning heart; and vascular, meaning vessel) disease with narrowed blood vessels.

Aspirin can keep blood flowing in the obstructed vessels and thus prevent heart attacks and strokes; but it can also increase the risk for strokes that are caused by bleeding in the brain. Most physicians attempt to lower such risks by asking their patients to keep their daily aspirin consumption to a low dose 81 mg “baby” aspirin.

How does aspirin affect your teeth and gums?
Be sure to let your medical and dental professionals know you are taking aspirin, and how much you take. Also tell us about other OTC medications you take, including herbal medications and supplements, because they may interact with aspirin to cause side effects.

If you have been told to take aspirin because of a cardiac condition or procedure, be sure to follow your recommended treatment. Do not suddenly discontinue aspirin therapy; doing so can increase your risk for heart attack and stroke. Ask us if you should stop taking aspirin before a major dental or oral surgery, but do not stop taking it on your own. We will consult with your physician about your medical condition and let you know our recommendation. In most cases you can continue your aspirin therapy without causing excessive bleeding during the dental procedure.

Periodontal (gum) disease, though it may be invisible to everyone but your dentist, can have a powerful effect on your entire body. Not only is it dangerous to your teeth and jaws, but it can increase your risk of heart attack and stroke, cause preterm births in pregnant women, and affect blood sugar control in diabetics.

Diabetics are our subject for today. Symptoms of diabetes include abnormally high levels of glucose (a form of sugar) in the blood, leading to frequent urination, excessive thirst, blurred vision, unexplained weight loss, and loss of energy. The disease can also cause severe complications in various parts of the body.

Normally, glucose, your body's main energy source, is kept under control by a hormone called insulin, which is made by an organ called the pancreas. In type 1 diabetes, a person's pancreas does not produce enough insulin to deal with all the glucose in his or her blood. In type 2 diabetes — a condition related to increased age, physical inactivity, overweight, and heredity — the pancreas may produce enough insulin, but the body is not able to use it effectively. This condition is called insulin resistance.

People with type 1 diabetes need insulin to survive. Type 2 may be treated with exercise, diet, medications, and insulin supplements.

Serious complications of diabetes range from kidney failure, blindness, and nerve damage to infections that do not heal, gangrene and amputation of limbs.

Diabetes and periodontal disease seem to have reciprocal effects on each other. Diabetics are more likely to have periodontal disease than non-diabetics; and those with periodontal disease are likely to face worsening blood sugar control over time.

Periodontal disease (from “peri”, meaning around and “odont”, meaning tooth), is caused by dental plaque — a film of bacteria that settles on your teeth and gums every day. It's what you remove with daily brushing and flossing. Any bacteria that remain cause inflammation, which can lead in the worst cases to loss of bone and eventual loss of teeth.

The close relationship of diabetes and periodontal disease probably results from changes in the function of immune cells responsible for healing. Inflammation is a part of normal wound healing — but chronic or prolonged inflammation can destroy the tissues it was meant to heal. This may be a major factor in the destructive complications of diabetes.

Many of these complications begin in the blood vessels. Like the eyes and the kidneys, gum tissues are rich in blood vessels. Gum tissues are also under constant attack from bacteria. If you are a diabetic, effective plaque control, along with regular professional dental cleaning, can have positive effects not only on periodontal disease, but also on control of your blood glucose level.

If you have missing teeth, dental implants are the state-of-the-art tooth replacement system. They act as substitutes for natural tooth roots, stabilizing the bone with which they fuse and become integrated with. This protects the remaining bone and prevents its further loss, the natural occurrence after the natural teeth are lost. Done correctly, implants can offer a long-term solution to the problem of missing teeth.

Key factors assuring dental implant success are having an experienced dental team consisting of:

1. A surgeon (periodontist or oral surgeon, or dentist trained in surgical techniques to place the implants)
2. A dental technician who will design the crowns (tooth portion of the implant)
3. A restorative dentist to place the crowns

The whole team is necessary to plan the process as well as carry out their individual roles. They will ensure that there is enough bone and that it is in the right place prior to treatment to allow for proper implant position, and that the implant/s are correctly placed, which is necessary to allow for natural aesthetics and proper function.

Replacing missing teeth is imperative to maintaining normal oral health and function. Dental implants will help support the entire structure of the face. If back teeth are lost, the vertical height of the lower face and mouth can begin to collapse, negatively impacting biting function and causing creasing and cracking of the lips and facial skin, resulting in a prematurely aged look.

Implants differ from bridgework in several ways, making them the most favorable option for tooth replacement in many cases. For starters, they do not affect adjacent teeth, nor do they decay like teeth, and they are less susceptible to gum disease. In the long-term, implants are a more cost-effective solution based on the fact that once they are placed, their life expectancy is longer than bridgework.

If you have missing teeth that have negatively affected your appearance, self-confidence, and ability to chew, call us today to talk about the possibility of replacing them with dental implants. To learn more about the use and capabilities of dental implants, read the Dear Doctor magazine article “Dental Implants: Evaluating Your Options For Replacing Missing Teeth.”

Tooth decay is not trivial. It's a worldwide epidemic, one of the most common of all diseases — second only to the common cold. It affects more than one fourth of U.S. children of ages 2 to 5 and half of those 12 to 15. Among adults, tooth decay affects more than ninety percent of those over age 40.

Prevention of cavities starts with a healthy diet and effective brushing and flossing, but it is much more complex than that. Three strategies for reducing dental caries (tooth decay) include:

Protect with Fluoride and Sealants
This works best when fluoride is applied to the crystalline coating of your child's teeth just after they push through the gums (erupt). The fluoride becomes incorporated into the tooth's surface and acts as a barrier to decay. Studies have shown that low doses of fluoride are safe and effective.

Dental sealants are used as a companion to fluoride because they seal tiny pits and fissures in the tooth's structure, creating an even stronger barrier.

Modify Oral Bacteria
Every mouth contains bacteria, no matter how well you clean your teeth. Not all bacteria cause tooth decay. The problem bacteria are those that produce acid as a byproduct of their life processes. We can identify acid-producing bacteria in your mouth, you can reduce their concentrations using antibacterial mouthrinses such as chlorhexidine, and pH neutralizing agents (substances that reduce the amount of acid).

Reduce Sugars in Your Diet
Bacteria in your mouth ferment sugars and other carbohydrates, producing acids that eat into the mineralized outside structure of your teeth, the enamel. So eating fewer sugars — particularly added sugars such as those in juices, sodas, candy and other sweets — will help prevent decay. Your total sugar intake should be less than fifty grams, or about ten teaspoons, per day. If you begin to read labels showing sugar content of common foods, you may be surprised at the amount you consume without knowing it.

If you must snack between meals, non-sugary snacks like raw vegetables and fresh fruits create a better environment for your teeth.

Xylitol, an “alcohol sugar” used in some chewing gums and dental products, has been shown to reduce decay-producing bacteria.

Try these easy strategies to keep your teeth healthy and functional throughout your lifetime.
