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.

There’s a lot to like about replacing a missing tooth with a dental implant. This state-of-the-art restoration is by far the most durable and life-like option available. And unlike other replacement options implants stimulate bone growth, a major concern after tooth loss.
For that reason we encourage getting an implant as soon as possible — for adults, that is. We don’t recommend implants for younger patients because even a teenager’s jaws haven’t yet reached full maturity. Because it attaches to the jaw differently, an implant can’t move with the growing jaw as real teeth do. It would eventually look as if it were sinking into the jaw below the gum line or being left behind as the rest of the jaw grows.
It’s best, then, to postpone placing an implant until the jaw fully matures, usually in a patient’s early twenties. In the meantime, there are some things we can do to prepare for a future implant while also restoring the tooth with a temporary replacement.
As previously mentioned, our biggest concern is bone health. Like other living tissue, bone has a growth cycle of older cells dissolving and newer ones forming in their place. The teeth transmit the pressure produced when we chew to the bone to stimulate this growth. With the absence of a tooth, the adjacent bone no longer receives this stimulation — the growth cycle slows and may eventually lead to bone loss.
We can help this situation by placing a bone graft in the missing tooth socket at the time of extraction. The graft serves as a scaffold that’s eventually taken over and replaced by new bone growth. We can also try to control how fast the graft is replaced by using grafting material that’s slowly removed and lasts longer — often a preferable situation if an implant is years away.
As for appearance, we can create a custom partial denture or even a type of bridge that bonds a prosthetic tooth to neighboring teeth without significantly altering them. If the patient undergoes orthodontic treatment it’s also possible to add prosthetic teeth to an orthodontic appliance.
Eventually, we’ll be able to provide the permanent solution of a dental implant. With careful planning and measures to preserve bone health, there’s a good chance the outcome will be worth the wait.

One of the key parts to an effective oral disease prevention plan is practicing daily oral hygiene to remove dental plaque. Both brushing and flossing are necessary for cleaning your teeth of this thin biofilm of bacteria and food particles most responsible for tooth decay and periodontal (gum) disease.
But as important as they are, these two essential hygiene tasks aren’t the end-all-be-all for lowering your disease risk. For the best protection, you should also visit your dentist at least twice a year for thorough dental cleanings. That’s because plaque you might have missed can turn into something much more difficult to remove: calculus.
Also known as tartar, calculus is hardened deposits of plaque. The term comes from the Latin word meaning “small stone,” an apt description of its texture on tooth surfaces. Although not the same as the branch of mathematics that bears the same name, both derive from the same Latin word: Merchants and traders centuries ago used small stones to “calculate” their various transactions.
Over time soft and pliable dental plaque hardens into calculus, in part due to a reaction with saliva. Because of the difficulty of accessing all tooth surfaces, calculus can form even if you have an effective daily hygiene practice.
Once formed, calculus can adhere to teeth so tenaciously, it’s impossible to remove it with brushing and flossing. But dentists and hygienists can remove calculus safely with special tools called scalers.
And it should be removed or it will continue to foster bacterial growth. This in turn increases the chances for infections that attack the teeth, gums or underlying bone. Keeping it under control will therefore diminish your risk for developing dental disease.
Although there are other factors like heredity that can affect your disease risk, keeping your mouth clean is the number one thing you can do to protect your teeth and gums. A daily hygiene practice and regular dental visits will help ensure plaque and its calcified form calculus won’t be a problem.
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.
When you’re buying a tool or appliance, you compare brands for the best quality you can afford. There’s another important item that deserves the same level of scrutiny: your toothbrush. Choosing the right one for you can make a huge difference in your oral hygiene effectiveness.
But a visit to your store’s dental care aisle can dim your enthusiasm. You have plenty of options involving all manner of shapes, sizes and features. Perhaps too many: After a while, the sheer number of choices can paralyze your decision-making process.
You can streamline this selection process by concentrating on a few important toothbrush basics. First up for consideration: the bristles. While you may think a good stiff brush would be best, it’s actually the opposite—most dental professionals recommend softer bristles. That’s because hard bristles can potentially damage your teeth and gums over time.
Softer bristles are gentler on your teeth and just as effective for removing plaque, if you use the right technique and thoroughly brush all tooth surfaces. And look for rounded bristles, which are friendlier to your gums.
Next, look for a brush that feels right in your hand. If you have problems with manual dexterity, look for one with an oversized handle. Some brushes come with angled necks and tapered heads, which you may find effective in reaching less accessible back teeth. This might mean trying different brushes until you get one that’s right for you. Don’t worry, though, you’re not buying a brush for life—in fact, you should change out your brush every three to six months.
You’ll also rarely go wrong buying a toothbrush with the American Dental Association Seal of Acceptance on the packaging. This seal signifies the toothbrush has undergone testing and met the ADA’s standards for hygiene effectiveness. While some manufacturers of effective brushes don’t pursue this seal, you can be sure one with it has passed the test of quality.
It makes all the difference in the world having the right tool for the job. Be sure your toothbrush is the right one for you.
