Teeth are naturally strong and durable — if we can prevent or control dental disease like tooth decay or gum disease, they can last a lifetime. Still, teeth do wear gradually as we age, a fact we must factor into our dental care as we grow older.
Sometimes, though, the wear rate can accelerate and lead to problems much earlier — even tooth loss. There are generally four ways this abnormal wear can occur.
Tooth to tooth contact. Attrition usually results from habitual teeth grinding or clenching that are well beyond normal tooth contact. Also known as bruxism, these habits may occur unconsciously, often while you sleep. Treatments for bruxism include an occlusal guard worn to prevent tooth to tooth contact, orthodontic treatment, medication, biofeedback or psychological counseling to improve stress coping skills.
Teeth and hard material contact. Bruxism causes abrasion when our teeth regularly bite on hard materials such as pencils, nails, or bobby pins. The constant contact with these and other abrasive surfaces will cause the enamel to erode. Again, learning to cope with stress and breaking the bruxism habit will help preserve the remaining enamel.
Chronic acid. A high level of acid from foods we eat or drink can erode tooth enamel. Saliva naturally neutralizes this acid and restores the mouth to a neutral pH, usually within thirty minutes to an hour after eating. But if you’re constantly snacking on acidic foods and beverages, saliva’s buffering ability can’t keep up. To avoid this situation, refrain from constant snacking and limit acidic beverages like sodas or sports drinks to mealtimes. Extreme cases of gastric reflux disease may also disrupt your mouth’s pH — seek treatment from your medical doctor if you’re having related symptoms.
Enamel loss at the gumline. Also known as abfraction, this enamel loss is often caused by receding gums that expose more of the tooth below the enamel, which can lead to its erosion. Preventing and treating gum disease (the leading cause of receding gums) and proper oral hygiene will lower your risks of receding gums and protect tooth enamel.

While tooth decay and periodontal (gum) disease destroy more teeth than any other causes, both of these diseases are largely preventable with proper oral hygiene and dental treatment. It’s more than possible, then, to enjoy a lifetime of healthy, disease-free teeth.
But even with healthy teeth, the effects of aging will cause tooth wear over time. And although we can’t prevent the aging process from occurring altogether, there are steps we can take not to accelerate the process.
Most tissues, including bone and teeth, have a growth cycle in which older cells are broken down (known as catabolism), removed and replaced by newer cells (anabolism). As we develop during childhood, the growth phase exceeds breakdown; when we reach adulthood, the two phases come into equilibrium. But as we age, breakdown will gradually overtake growth. This aging effect results in, among other outcomes, tooth wear.
“Normal” wear appears to be greatest — and most visible — along the biting surfaces of the teeth. The forces generated when we bite or chew causes enamel to erode over time. Unfortunately, you can accelerate this process through bad oral habits: clenching or grinding teeth, often times at night while you sleep, as well as habitually chewing on hard objects like nails or pencils.
Normal forces generated when we bite or chew are actually beneficial for dental health — they help stimulate bone growth. But when they exceed their normal range as when we clench or grind our teeth, they can increase tooth wear and cause other problems such as diminished function or changes in appearance, such as a shortened facial height.
To slow the rate of wear, it’s important to modify any behaviors that may be contributing to it. In many cases an occlusal night guard worn while you sleep helps prevent teeth clenching. You may also need assistance with stress management, a major trigger for these kinds of habits, through biofeedback therapy or counseling.
If you’ve already encountered excessive wear, bonding techniques using colored composite resin, veneers or crowns that attach directly to the teeth can restore lost function and rejuvenate the appearance and color of your teeth. We can perform a “smile analysis” to determine if one of these techniques is right for you to help you regain a more youthful and attractive smile.
