You may not realize it, but the simple act of eating can generate a tremendous amount of force on teeth and jaws. Fortunately, your teeth can absorb much of this biting force — but within limits. If the force exceeds normal limits on a continual basis, you may begin to notice aching teeth or sore jaws, and we may begin to notice unusual tooth wear during your dental checkups.
The most common cause for this is a chronic habit of grinding or clenching the teeth, also known as bruxism. It can manifest itself by teeth grinding against each other, teeth pressing against soft tissue (as with thumb-sucking) or biting or chewing on hard objects such as pencils or nails. We commonly see bruxism with patients who are experiencing excessive stress, sleep-related problems or as a result of lifestyle habits such as smoking or excessive alcohol consumption. You may not even be consciously aware of it as in the case of bruxism that occurs while you sleep, but your sore jaws in the morning (as well as your sleeping partner’s complaints of noise) may be evidence of it.
Treatment involves a two-part approach. First, we want to relieve the pain symptoms and stop the damage. To relieve pain we’ll often prescribe mild, anti-inflammatory or muscle-relaxant drugs, or perhaps medication to help you sleep better. We may also design a bite guard for wear on your upper teeth at night: the lower teeth will tend to glide or skate on the wear-resistant plastic and prevents them from placing excessive forces on your teeth.
The other part is to address the underlying cause for long-term results. If the habit arises from severe stress or other lifestyle issues, we may recommend biofeedback therapy or psychotherapy to improve your coping mechanisms. If an abnormality like a bad bite (malocclusion) is an underlying factor, we may recommend a minor bite adjustment by reshaping the teeth to lessen the bite impact.
The right course of action depends on a thorough dental examination to determine the exact nature of your clenching or grinding habit. From there we can discuss your options on how to relieve the soreness and pain, as well as prevent problems in the future.

Tooth wear, especially on biting surfaces, is a normal part of aging — we all lose some of our tooth enamel as we grow older. Even primary (“baby”) teeth may show some wear before they’re lost. But there’s also excessive, premature tooth wear caused by disease or abnormal biting habits. This type of wear is cause for concern and action before it leads to tooth loss.
Normal tooth wear occurs because of what teeth naturally do — bite and chew. When teeth come together as we eat they generate a modest amount of force: between 13 and 23 pounds. Our teeth also make brief contacts hundreds to thousands times a day. Again, this produces force, though not to the extent we see with biting and chewing: somewhere between 0.75 and 7.5 pounds. These glancing contacts are actually good for dental health because they provide needed stimulation to the teeth and jaws that help the body maintain healthy bone and tooth attachments.
But parafunctional (outside the normal function) habits like teeth grinding or foreign object chewing can greatly increase the generated force, up to 230 pounds. These may result in noticeable symptoms like fractures or loose teeth, but not always — the damage may not be noticeable until much later in the form of excessive tooth wear.
These parafunctional habits aren’t the only cause for excessive tooth wear; tooth decay can weaken the tooth structure, making it more susceptible to wear. And, some restorative materials used for fillings may also affect the rate of wear.
Because excessive tooth wear may or may not present with immediate symptoms, it’s important to maintain regular dental checkups to monitor the condition of your teeth. Our training and experience helps us identify signs of excessive tooth wear and, depending on the extent of damage, work with you on a treatment plan. You should also keep us informed about oral habits, especially teeth grinding, thumb sucking or foreign object chewing (toys, nails, pencils, etc.).
Your teeth will wear as you grow older. By keeping a close eye on your teeth, we’ll help you keep that wear at a normal rate.
