Think dental implants only replace individual teeth? Think again—this premier technology can also support other kinds of restorations to provide better stability and comfort. And, they also help improve bone health when incorporated with any type of tooth replacement options, especially dentures.
Although traditional dentures have enjoyed a long, successful history as a tooth replacement solution, they can interfere with bone health. That’s because regular dentures fit in the mouth by resting on the bony ridges of the jaw, which has implications for the bone.
As living tissue, bone goes through a growth cycle with older bone cells dying and dissolving and newer cells forming to take their place. The teeth play a role in this growth cycle — the forces generated when we chew travel up through the teeth and help stimulate bone growth. When teeth go missing, however, so does this stimulus.
Traditional dentures can’t replace this missing stimulus. In fact, the constant pressure of dentures on the jaw may even accelerate bone loss. A sign this is happening occurs when the dentures’ once tight fit begins to loosen and they become uncomfortable to wear.
Implant-supported dentures can help eliminate this problem. We first surgically place a few implants in the jaw, the number determined by which jaw (the lower requires less) and whether the denture is removable or fixed. If removable, the denture has connective points that match the implant locations — you simply connect them with the implants. If fixed, the denture is screwed into the implants to hold it in place.
So, how does this help bone health? For one, the denture no longer puts as much pressure on the jaw ridges—the main support comes from the implants. And, the implants themselves encourage bone stimulation: The titanium in the implant has a special affinity with bone cells that naturally grow and adhere to its metal surface. This natural integration between implant and bone can stop bone loss and may even help reverse it.
If you’re interested in implant-supported dentures, you’ll first need to undergo a full dental exam with your dentist. These restorations aren’t appropriate for all dental situations. But, if they can work for you, you may be able to enjoy the benefits of an implant-supported restoration.

Your teeth face a hostile environment populated by disease-causing bacteria. But your teeth also have some “armor” against these microscopic foes: enamel. This hard outer tooth layer forms a barrier between harmful bacteria and the tooth’s more vulnerable layers of dentin and the inner pulp.
But although it’s tough stuff, enamel can erode when it comes into contact with high concentrations of mouth acid. Losing substantial amounts of enamel could leave your teeth exposed to disease.
So, here are 3 things you can do to help protect your enamel so it can keep on protecting you.
Careful on the brushing. Brushing removes dental plaque, a thin bacterial film on teeth most responsible for dental disease. But be careful not to brush too often, too hard and too quickly after eating. Brushing more than twice a day can cause gum recession and enamel wear; likewise, brushing too aggressively. You should also wait at least 30 minutes after eating to brush to give your saliva sufficient time to neutralize any acid. You could lose tiny bits of softened enamel brushing too soon.
Cut back on acidic foods and beverages. Spicy foods, sodas and, yes, sports and energy drinks all contain high amounts of acid that can increase your mouth’s acidity. It’s a good idea, then, to reduce acidic foods and beverages in your diet. Instead, eat less spicy foods and drink primarily water or milk. Also, look for foods and beverages with calcium, which helps increase your enamel’s ability to remineralize after acid contact.
Don’t eat right before bedtime. There are a lot of reasons not to eat just before you hit the hay—and one of them is for protecting your tooth enamel. Saliva normally neutralizes acid within a half hour to an hour after eating. While you’re sleeping, though, saliva production decreases significantly. This in turn slows its neutralizing effect, giving acid more contact time with enamel. So, end your eating a few hours before you turn in to avoid too much acid remaining on your teeth.
Besides their life-likeness, implants are also prized for their high success rate. More than ninety-five percent of implants continue to function effectively after ten years.
Implants’ advanced technology explains some of their reliability and longevity—they’re as close to natural teeth as we’re now able to achieve. But their impressive success rate also owes to the detailed protocols that dentists follow to install them. One critical part of these protocols is ensuring a patient has enough bone in their jaw to support and precisely situate the implant for the best functional and aesthetic outcome.
Unfortunately, there are situations where a patient doesn’t have enough bone to achieve a satisfactory result. This often happens if there’s been months or years between losing the tooth and considering an implant. The reason why relates to the nature of bone as living tissue.
Like other cellular tissues in the body, bone has a life cycle: Older, worn-out cells die and are absorbed by the body, and new cells form to replace them. The growth cycle in the jaw receives stimulation from the forces generated when we chew, which travel up through the teeth to the bone.
However, this stimulation stops after tooth loss for the related area of bone, which can slow new bone growth. Over time, the volume and density of the bone around a missing tooth gradually decreases, enough eventually to make an implant impractical.
Insufficient bone volume, though, doesn’t necessarily mean an implant is out of the question. We may be able to address the problem by attempting to regenerate the bone through grafting. This is a procedure in which we insert graft material into the affected area of the jawbone. The graft then becomes a scaffold upon which bone cells can grow. After several months, we may have enough regenerated bone to support an implant.
If there’s been too much bone loss, we may still need to consider another form of restoration. But if we can successfully build up the bone around your missing tooth, this premier restoration for replacing lost teeth could become a reality for you.
