Tooth loss is a problem that affects many seniors—and since May is Older Americans Month, this is a good time to talk about it. Did you know that more than a quarter of adults over age 75 have lost all of their natural teeth? This not only affects their quality of life but poses a significant health risk.
According to a study in The Journal of Prosthodontics, significant tooth loss is associated with increased risk for malnutrition—and also for obesity. If this seems like a contradiction, consider that when you have few or no teeth, it’s much easier to eat soft, starchy foods of little nutritional value than it is to eat nutritious fresh fruits and vegetables. If all of your teeth are missing, it’s especially critical to replace them as soon as possible.
There are several ways to replace a full set of missing teeth, including removable dentures, overdentures, and fixed dentures:
Removable dentures are the classic replacement teeth that you put in during the day and take out at night. (However, if you suffer from sleep apnea, research has found that keeping dentures in at night may help keep the airway open, so if you have this condition, be sure to mention it to your doctor and dentist it). Dentures have come a long way in terms of how convincing they look, but they still have some disadvantages: For one thing, they take some getting used to—particularly while eating. Also, wearing removable dentures can slowly wear away the bone that they rest on. As that bone gradually shrinks over time, the dentures cease to fit well and require periodic adjustment (re-lining) or a remake.
Overdentures are removable dentures that attach onto a few strategically placed dental implants, which are small titanium posts placed in the bone beneath your gums. Strong and secure, implants prevent the denture from slipping when you wear it. Implants also slow the rate of bone loss mentioned above, which should allow the denture to fit better over a longer period of time. The ability to maintain hygiene is easier because you can remove them for cleaning.
Fixed implant-supported dentures are designed to stay in your mouth all the time, and are the closest thing to having your natural teeth back. An entire row of fixed (non-removable) replacement teeth can usually be held in place by 4-6 dental implants. Dental implant surgery is an in-office procedure performed with the type of anesthesia that’s right for you. After implants have been placed and have integrated with your jaw bone—generally after a few months—you can enjoy all of your favorite foods again without worry or embarrassment.

Today's dental restorations are truly amazing. Not only are they life-like and functional, they can endure for many years a hostile environment of bacteria, acid and heavy biting forces.
Even so, you'll still need to take care of your restorations to help them last. Here's how to extend the life of 3 common forms of dental work.
Fillings. We use fillings, both metal amalgam and tooth-colored materials, to repair holes or cavities in teeth caused by tooth decay. Although strong, dental fillings can break if you subject them to abnormally high biting force (like chewing ice). There's also a chance that if a slight separation occurs between the filling and tooth, bacteria can take up residence and reignite the decay process. To prevent this, practice a daily regimen of oral hygiene to clean away bacterial plaque—and reduce sugar in your diet, a prime food source for bacteria.
Veneers. Usually made of thin porcelain, veneers are bonded to the front of teeth to mask chips, stains, gaps or other blemishes. But although they're strong, veneers aren't immune to damage. Habits like biting nails, the aforementioned ice chewing or unconsciously grinding your teeth could cause a chipped veneer. And if periodontal (gum) disease causes your gums to recede, the exposed part of the tooth may look noticeably darker than the veneer. To protect your veneers and their appearance, avoid habits like ice chewing, and seek treatment for teeth grinding and dental disease.
Bridgework. Bridges are used to replace one or more missing teeth. Traditional bridges use the natural teeth on either side of the gap to support the bridge; for a single missing tooth, implants are a preferable option because they don't require permanently altering the neighboring teeth to support it. With either option, though, you should brush and floss around the restoration to reduce the risk of dental disease. Infections like gum disease or tooth decay could eventually weaken the bridge's supporting teeth or gum disease can damage an implant's gum and bone support.
With any dental restoration, be sure to practice daily oral hygiene, eat a nutritious, low-sugar diet, and see your dentist regularly for cleanings and checkups. Taking care of your dental work will help it take care of you for a long time to come.
Somewhere around age 6, your child’s primary (baby) teeth will begin to give way to their permanent set. If all goes well, you’ll notice all the front teeth erupting in the right position: the top teeth slightly overlapping the bottom and all coming in without crowding.
Sometimes, though, the process doesn’t occur as it should and a bad bite (malocclusion) may develop. You can get a head start on treatment if you know what to look for. Here are a few problems for which you should see a dentist — or more likely an orthodontist — for a thorough evaluation.
Spacing problems. Teeth should normally come in right next to each other without a noticeable gap. But if you notice excessive space between the permanent front teeth especially, this may be an indication there’s a discrepancy in size between the teeth and the jaws. At the other end of the spectrum, if teeth on the same arch appear to overlap each other, this indicates crowding in which there’s not enough space for the teeth to erupt properly.
Bad bites. Malocclusions can take different forms. In an underbite, the front bottom teeth bite in front of the upper teeth. If there’s a noticeable gap between the upper and lower teeth when the jaws are closed, this is known as an open bite. Front teeth biting too far down over the lower teeth is a deep bite and could even include biting into the soft tissue of the hard palate. Cross bites can occur in either the front or back teeth: if in the front, some of the lower teeth will bite in front of the upper; if in the back, some of the lower teeth bite outside the upper rather than normally on the inside.
Abnormal eruptions. You should also be alert for protusions, in which the upper teeth or the jaw appears to be too far forward, or retrusions, in which the lower teeth or jaw appears to be too far back. You should also be concerned if permanent teeth erupt far from their normal position — this is especially likely if the primary tooth was also out of position, or was lost prematurely or not in the right order.
