Put an End to Bad Oral Habits to Slow the Rate of Tooth Wear

While tooth decay and periodontal (gum) disease destroy more teeth than any other causes, both of these diseases are largely preventable with proper oral habits 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 ageing will cause tooth wear over time. And although we can’t prevent the ageing 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 and oral habits. This ageing 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 behaviours 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 counselling. (oral habits) If you’ve already encountered excessive wear, bonding techniques using coloured composite resin, veneers or crowns that attach directly to the teeth can restore lost function and rejuvenate the appearance and colour 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.
