Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

If you’re facing cancer treatment, we wish you the best outcome possible. Treating this disease has advanced tremendously in recent decades, but the available options are still often challenging to endure. It will be your primary focus for the foreseeable future.
As a dental provider we also want you to be aware how the two main treatments, chemotherapy and radiation, could adversely affect your teeth and gums, especially if you’re receiving radiation therapy near the head and neck. The aim of cancer treatment is to attack and destroy cancer cells to prevent their growth. Unfortunately, it can also destroy neighboring healthy cells and lead to harmful consequences in different parts of the body, including the mouth.
Salivary glands, for example, are especially vulnerable to damage during cancer treatment. This could create a situation where the mouth no longer produces adequate saliva flow, leading to a condition called xerostomia or dry mouth. Besides a lot of discomfort, restricted saliva flow can also increase your risk of tooth decay and other dental diseases. This is because saliva is the body’s acid neutralizer (acid can erode tooth enamel) and its first line of defense against microbial infection.
To guard against this, it’s important to support salivary flow as much as possible if you experience dry mouth symptoms during treatment (as well as beyond—it’s possible the damage to these glands could be permanent). Since some medications also contribute to dry mouth, you should speak with your physician about the prescriptions you’re taking: if any have dry mouth side effects ask if there’s an alternative drug without these side effects. You should also drink more water during the day and especially when taking medications. And consider substances like xylitol gum that can help boost saliva flow.
Unfortunately, it may not be possible to fully avoid the effects of these treatments on your teeth and gums. So, be sure you keep up daily brushing and flossing and see your dentist regularly for cleanings and checkups. If necessary, there are a number of restoration options to restore your smile after you’ve completed your treatment.
If there's anything that makes Alfonso Ribeiro happier than his long-running gig as host of America's Funniest Home Videos, it's the time he gets to spend with his family: his wife Angela, their two young sons, and Alfonso's teenaged daughter. As the proud dad told Dear Doctor–Dentistry & Oral Health magazine, "The best part of being a father is the smiles and the warmth you get from your children."
Because Alfonso and Angela want to make sure those little smiles stay healthy, they are careful to keep on top of their kids' oral health at home—and with regular checkups at the dental office. If you, too, want to help your children get on the road to good oral health, here are five tips:
- Start off Right—Even before teeth emerge, gently wipe baby's gums with a clean, moist washcloth. When the first teeth appear, brush them with a tiny dab of fluoride on a soft-bristled toothbrush. Schedule an age-one dental visit for a complete evaluation, and to help your child get accustomed to the dental office.
- Teach Them Well—When they're first learning how to take care of their teeth, most kids need a lot of help. Be patient as you demonstrate the proper way to brush and floss…over and over again. When they're ready, let them try it themselves—but keep an eye on their progress, and offer help when it's needed.
- Watch What They Eat & Drink—Consuming foods high in sugar or starch may give kids momentary satisfaction…but these substances also feed the harmful bacteria that cause tooth decay. The same goes for sodas, juices and acidic drinks—the major sources of sugar in many children's diets. If you allow sugary snacks, limit them to around mealtimes—that gives the mouth a chance to recover its natural balance.
- Keep Up the Good Work—That means brushing twice a day and flossing at least once a day, every single day. If motivation is an issue, encourage your kids by letting them pick out a special brush, toothpaste or floss. You can also give stickers, or use a chart to show progress and provide a reward after a certain period of time. And don't forget to give them a good example to follow!
- Get Regular Dental Checkups—This applies to both kids and adults, but it's especially important during the years when they are rapidly growing! Timely treatment with sealants, topical fluoride applications or fillings can often help keep a small problem from turning into a major headache.
Bringing your kids to the dental office early—and regularly—is the best way to set them up for a lifetime of good checkups…even if they're a little nervous at first. Speaking of his youngest child, Alfonso Ribeiro said "I think the first time he was really frightened, but then the dentist made him feel better—and so since then, going back, it's actually a nice experience." Our goal is to provide this experience for every patient.
If you have questions about your child's dental hygiene routine, call the office or schedule a consultation. You can learn more in the Dear Doctor magazine article “How to Help Your Child Develop the Best Habits for Oral Health.”
In many parts of the country, summer is often a synonym for "blast furnace" and can be downright hot and miserable. If you find yourself in such a climate, it's imperative that you drink plenty of water to beat both the heat and heat-related injuries. Your teeth and gums are another reason to keep hydrated during those hot summer months.
Your body needs water to produce all that saliva swishing around in your mouth. When you have less water available in your system, the production of this important bodily fluid can go down—and this can increase your risk of dental disease. That's because saliva performs a number of tasks that enhance dental health. It helps rinse the mouth of excess food particles after eating that could become a prime food source for disease-causing bacteria. It also contains antibodies that serve as the first line of defense against harmful microorganisms entering through the mouth.
Perhaps saliva's most important role, though, is protecting and strengthening enamel, the teeth's outer "armor" against disease. Although the strongest substance in the body, enamel has one principal foe: oral acid. If the mouth's normally neutral pH becomes too acidic, the minerals in enamel begin to soften and dissolve. In response, saliva neutralizes acid and re-mineralizes softened enamel.
Without a healthy salivary flow protecting the mouth in these different ways, the teeth and gums are vulnerable to assault from bacteria and acid. As they gain the upper hand, the risk for tooth decay or periodontal (gum) disease can skyrocket. Keeping yourself adequately hydrated ensures your body can produce an ample flow of saliva.
By the way, summer heat isn't the only cause for reduced saliva: Certain prescription medications may also interfere with its production. Chemotherapy and radiation, if targeting cancer near the head or neck, can damage salivary glands and impact flow as well.
If you have reduced saliva from medication you're taking, talk to your doctor about switching to an alternative prescription that doesn't affect saliva production. If you're undergoing cancer treatment, be extra vigilant about your oral hygiene practice and regular dental visits. And as with summer heat, be sure you're drinking plenty of water to help offset these other effects.
Even when it's hot, summertime should be a time for fun and relaxation. Don't let the heat ruin it—for your health or your smile.
Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
