If you do the right things—keep your teeth clean, see the dentist regularly, and eat a "tooth-friendly" diet—you stand a good chance of having healthy teeth and gums later in life. Even so, after eating well over 75,000 meals by age 70, you can expect some wear from all that biting and chewing.
But there's normal wear—and then there's excessive wear, which can be caused by a variety of factors. When it occurs, accelerated wear can increase your risk of dental disease—and your shorter-toothed smile can make you look older than your actual age.
Here are 3 dental problems that can lead to accelerated tooth wear, and what you can do about them.
Tooth decay. This dental disease can severely weaken a tooth's protective enamel surface, which can in turn increase wear. You can minimize your chances of developing tooth decay by brushing and flossing your teeth daily and undergoing regular dental cleanings. And the sooner you receive treatment for any diagnosed decay, the less likely your enamel will suffer significant damage.
Poor bite. Properly aligned teeth mesh well together while biting and chewing, which minimizes wearing. But misalignments put undue stress on teeth that can lead to accelerated wear. By correcting a bite problem through orthodontics, we can properly align teeth so that they interact with each other normally for less wear.
Teeth grinding. This unconscious habit of gnashing or grinding teeth (often during sleep) can produce abnormally high biting forces. Among other adverse outcomes, this can also increase teeth wearing. If you grind your teeth, there are therapeutic methods that could reduce the habit. You can also obtain a custom night guard to reduce biting forces while you sleep.
If you've already experienced excessive dental wear, there are cosmetic options like porcelain veneers or dental bonding that can restore your smile to a more youthful appearance and help protect your teeth. But if you haven't reached that point, you can make sure you don't by taking care of your teeth and gums and seeking prompt dental treatment for problems leading to accelerated wear.

The humble squirrel—darlings to some, bird feeder-robbing nuisances to others—has its own month. Since 1995, the Squirrel Lovers Club of Chicago has celebrated October as Squirrel Awareness Month to pay tribute to this diverse family of rodents with over 270 species. It's also an opportunity to indulge in our favorite “squirrelly” fact: Squirrels' teeth don't stop growing.
And we do mean grow. A squirrel's four front incisors increase about 6 inches a year—a good thing since squirrels put those teeth through their paces gnawing through hard-shelled nuts and seeds. If they didn't keep growing, you'd see plenty of squirrels with worn-to-nothing front teeth.
We humans have some cause to be envious because, unlike squirrels, our permanent teeth stop growing by the time we reach adulthood. That could be a problem since nearly all of us encounter tooth wear as we age.
And it could be even worse. Bad habits like crunching ice, biting into hard foods or using our teeth as tools can contribute to accelerated wear. Some people also involuntarily clench or grind their teeth, creating higher than normal pressure that can wear down teeth.
Suffice it to say, it's worth the effort to quit conscious bad dental practices to prevent your teeth from wearing faster than normal. A teeth-grinding habit, though, may require more than willpower: We'll need to look at other ways to reduce its effect on your teeth.
First, you may want to try to reduce chronic stress, the top contributor to adult teeth grinding. Better stress management with the help of counseling, relaxation techniques, biofeedback or group therapy can all help reduce the occurrence of this destructive habit.
Such efforts, though, can take time. In the meantime, we may be able to help you reduce the effect of a grinding habit with a custom-made mouth guard. This plastic guard worn in the mouth prevents teeth from making hard contact with each other during grinding, and so it reduces the damaging forces that can wear down teeth.
By the way, if you've already experienced excessive tooth wear, not all hope is lost. We may be able to restore your teeth to normal length with the help of bonded porcelain veneers or crowns. After a thorough evaluation, we can give you options for turning back the “age clock” on your smile.
Our teeth may not continuously grow like squirrels', but we can still protect them from the effects of excessive wear. Good dental practices and habits—and restorative measures when necessary—can keep your smile looking as young as ever.
One of the unfortunate aspects of aging is tooth wear. Depending on your diet, years of biting and chewing can cause enamel along the biting surfaces to erode. Your body also can't replace enamel — so when it comes to teeth it's not a question of if, but how much your teeth will wear during your lifetime.
To make matters worse, certain conditions cause tooth wear to accelerate. Teeth softened by acids or tooth decay, for example, erode faster than healthier teeth. So will grinding habits: often fueled by stress, these include chewing on hard items like nails, pencils or bobby pins.
You may also grind your teeth, usually while you sleep. Normal biting and chewing produces pressure of about 13 to 23 pounds per square inch: grinding your teeth at night can well exceed this, even up into the hundreds of pounds.
There are some things we can do to alleviate these issues. For clenching and grinding habits, one primary step is to address stress through counseling or biofeedback therapy. For nighttime teeth grinding we can create a bite guard to wear while you sleep that will prevent your teeth from generating abnormal forces.
Finally, it's important that you take care of your teeth through daily oral hygiene, regular office cleanings and checkups, and a nutritious diet for maintaining strong bones and teeth. Keeping your teeth free from diseases that could compromise your enamel as well as other aspects of your mouth will help them stay as strong as possible.

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.

What is tooth wear?
“Tooth wear” refers to a loss of tooth structure that can make your teeth appear shorter or less even than they used to be. Wear starts with loss of outer covering of the teeth, known as enamel. Although enamel is the hardest structure in the human body — even harder than bone — it can wear away over time. If enough enamel is lost, the softer inner tooth structure known as dentin can become exposed, and dentin wears away much faster.
What causes tooth wear?
Tooth wear can be caused by any of the following:
- Abrasion: This is caused by a rubbing or scraping of the teeth. The most common source of abrasion is brushing too hard or using a toothbrush that is not soft enough. A removable dental appliance, such as a partial dentures or retainer, can also abrade teeth. Abrasion can also result from habits such as nail-biting and pen-chewing.
- Attrition: This is caused by teeth contacting each other. Habits that you might not even be aware of — such as grinding or clenching your teeth — can be quite destructive over time. That’s because they can subject teeth to 10 times the normal forces of biting and chewing.
- Erosion: Acid in your diet can actually erode (dissolve) the enamel on your teeth. Many sodas, sports drinks and so-called energy drinks are highly acidic; so are certain fruit juices. Eating sugary snacks also raises the acidity level in your mouth. If you can’t give up these snacks and drinks entirely, it’s best to confine them to mealtimes so your mouth doesn’t stay acidic throughout the day. Swishing water in your mouth after eating or drinking acidic or sugary substances can also help prevent erosion.
- Abfraction: This refers to the loss of tooth enamel at the “necks” of the teeth (the part right at the gum line). This type of wear is not thoroughly understood, though it is believed to result from excessive biting forces. Abrasion and erosion can contribute to this problem.
How is it treated?
The first step in treating any type of tooth wear is to determine the cause during a simple oral examination right here at the dental office. Once the cause has been identified, we can work together to reduce the stresses on your teeth. For example, you may need a refresher course on gentle, effective brushing techniques; or you might benefit from some changes to your diet. If you have a clenching or grinding habit, we can make you a nightguard that will protect your teeth during sleep or periods of high stress. Once we have dealt with the underlying cause, we can make your teeth look beautiful again by replacing lost tooth structure with bonding, veneers, or crowns. This will also allow your bite to function properly again.
