Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.
The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.
Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces). Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.
Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.
After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.
Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

Bite problems are quite common—as many as 75% of adults may have some form of orthodontic issue. Unfortunately, there's also something else just as common: that many people believe they're too old to correct it.
This belief is a myth—while there are factors that could prevent orthodontic treatment, age isn't necessarily one of them. If your teeth, gums and bone are sound and you're in reasonably good general health, you most likely can have a bite problem corrected even beyond middle age.
Why worry about it, though, if you've lived this long with misaligned teeth? For one thing, straightening teeth with braces or clear aligners can boost your dental health. Teeth that are in normal alignment are easier to keep clean of disease-causing bacterial plaque. You'll also find it easier to chew than if your bite is out of line.
A more attractive, straighter smile can also impact your social and professional life. Having a smile you're not embarrassed to show can boost your self-confidence and image. Research on people who've undergone orthodontic treatment in adulthood have found improvements in social connection and even expanded career opportunities.
Orthodontic treatment can make a difference with your health and life, no matter your age. But while the number of years you've lived won't necessarily make a difference, what those years have brought could rule it out.
If, for example, you've lost significant bone structure due to diseases like periodontal (gum) disease, your teeth may not be able to sustain the new position created by braces or aligners without a form of permanent fixation. If you have systemic conditions like severe cardiovascular disease, bleeding problems, leukemia or uncontrolled diabetes, orthodontic treatment could worsen those conditions. And certain prescription drugs may pose similar problems as well.
That's why you'll need to undergo a thorough dental exam, as well as provide a complete medical history to your orthodontist. If nothing prevents you from treatment, though, you may be able to regain a new smile, better health and a new confidence in life.
