You may have noticed, as you get older, that the enamel of your teeth is looking worn in certain areas. Sometimes tooth wear takes the form of a minor chipping or fracturing at the incisal (cutting) edges of the teeth, or a loss of tooth material from the area near the gum line. In more severe cases, worn teeth look quite a bit smaller than they used to. Why does this happen?
Some wear with age is natural. But too much wear can interfere with your bite, expose more sensitive inner parts of the tooth to decay, and give you a more aged appearance.
There are things you can control that affect wear:
Your habits: Clenching or grinding habits, also called “bruxism,” is a major cause of tooth wear. The motion of teeth sliding over each other with forces that are beyond what's normal for biting or chewing causes a mechanical removal of tooth enamel. This can happen during sleep or periods of high stress. In either case there are therapies available, such as a thin, professionally made mouthguard that prevents your teeth from coming into contact with each other. Holding foreign objects, such as nails and bobby pins, between your teeth can also cause wear.
Your diet: Tooth enamel can be eroded (dissolved away) by acidic beverages, such as sodas, sports drinks and juices. Frequent snacking on sugary foods encourages the growth of oral bacteria that produce acid as a byproduct — also leaving your teeth vulnerable to tooth decay. Your saliva can buffer the effects of the acid in your mouth in about half an hour; if you consume these types of foods and beverages continually, there won't be enough time for this to work.
We can restore the appearance and function of worn teeth in a variety of ways. Porcelain crowns and veneers, for example, can re-establish the normal thickness and length of teeth while improving their color and giving you a more youthful appearance.

Nightly snoring can be a sign of a dangerous condition called sleep apnea (from “a” meaning without and “pnea” meaning breath). When someone snores the soft tissues in the back of the throat collapse onto themselves and obstruct the airway, causing the vibration known as snoring.
If the obstruction becomes serious, it is called obstructive sleep apnea, or OSA. In such cases the flow of air may be stopped for brief periods, causing the person to wake for a second or two with a loud gasp as he attempts to catch his breath. This can cause heart and blood pressure problems, related to low oxygen levels in the blood. The obstruction and mini-awakening cycle can occur as many as 50 times an hour. A person with this condition awakens tired and faces the risk of accidents at work or while driving due to fatigue.
Studies show that sleep apnea patients are much more likely to suffer from heart attack, congestive heart failure, high blood pressure, brain damage and strokes.
What can be done to treat OSA?
Snoring, apnea, and OSA occur more frequently in people who are overweight. So start with losing weight and exercising.
At our office, we can design oral appliances to wear while sleeping that will keep your airway open while you sleep. These appliances, which look like sports mouth guards, work by repositioning the lower jaw, tongue, soft palate and uvula (soft tissues in the back of the throat); stabilizing the lower jaw and tongue; and increasing the muscle tone of the tongue.
Another approach is to use a Continuous Positive Airway Pressure (CPAP) bedside machine. These machines send pressurized air through a tube connected to a mask covering the nose and sometimes the mouth. The pressurized air opens the airway so that breathing is not interrupted.
Much less frequently, jaw surgeries may be recommended to remove excess tissues in the throat. These would be done by specially trained oral surgeons or ear, nose and throat specialists.
Diagnosis and treatment of OSA is best accomplished by joint consultation with your physician and our office. Contact us today to schedule an appointment to discuss snoring and OSA.
