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.

The lengths that some comedians will go to for a laugh! Actor Ed Helms, as dentist Stu Price, pulled out his own tooth in the movie The Hangover. Or did he? Turns out Helms really is missing a tooth, which never grew in. When he was in his late teens, he received a dental implant to make his smile look completely natural.
Helms told People magazine he wasn't exactly eager to remove the implant crown that had served him so well for almost 20 years, but there was no better way to do the famous tooth-pulling scene.
“We started to do different tests with prosthetics and blacking it out and nothing worked,” Helms told the magazine. Helms' dentist said it would be okay to take the implant crown out. “My dentist was really into it,” Helms said. The rest is movie history!
Congenitally missing (“con” – together with; “genital” – relating to birth) teeth are inherited and actually quite common. More than 20% of people lack one or more wisdom teeth, for example. These would not usually be replaced if missing (in fact, wisdom teeth are often removed) but it's a more serious issue when the missing tooth is in the front of the mouth — and not just for aesthetic reasons.
When a particular type of tooth is missing, it disrupts the pattern and function of the teeth. If left alone, sometimes the existing teeth will shift to close the gap. It's like removing a brick from an arch — the rest of the bricks would fall together in a different formation (or collapse entirely). And when upper and lower teeth don't come together properly, they can't function well.
The best treatment for this type of situation is the one Ed Helms had: a dental implant. They look and function like real teeth and do not attach to or damage adjacent teeth as other tooth-replacement options might.
It is important that a child with a congenitally missing tooth wait until jaw growth is complete — different for every person but usually in the late teens — before getting an implant. Otherwise, the artificial tooth might eventually appear too short when the person has stopped growing. In the meantime, there are temporary tooth replacements that can be made.
