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.
Today’s technologically advanced dentures aren’t your grandparents’ “false teeth.” Now made with superior materials and processes, you could almost forget you’re wearing them. But don’t let that cause you to leave them in for the night: While it may seem like a harmless thing to do, wearing dentures 24/7 may not be good for them or your health.
For one thing, around the clock denture wearing could worsen bone loss, already a concern with dentures and missing teeth. The forces generated when we chew on natural teeth stimulate new bone growth to replace older bone cells. When teeth go missing, though, so does this stimulus. Even the best dentures can’t restore this stimulation, so bone loss remains a risk.
And, dentures can accelerate bone loss because of the added pressure they bring to the bony gum ridges that support them. Wearing them all the time deprives the gums of any rest, further speeding up the pace of bone loss. Losing bone volume not only affects your overall oral health, it will gradually loosen your dentures’ fit and make them uncomfortable to wear.
Another problem: You may clean your dentures less frequently if you don’t take them out at night. Lack of cleaning can encourage bacterial growth and lead to disease. Studies show that people who don’t take their dentures out at night have more dental plaque accumulation, gum inflammation and higher blood counts of the protein interleukin 6, indicating the body is fighting infection.
And that’s not just a problem for your mouth. Continuous denture wearing could make you twice as likely to develop life-threatening pneumonia as someone who routinely takes their dentures out.
These and other concerns make nightly denture removal a good practice for your health’s sake. While they’re out, it’s also a good time to clean them: Manually brush them for best results (be sure you’re only using regular soap or denture cleanser—toothpaste is too abrasive for them). You can then store them in clean water or a solution designed for dentures.
Having said all that, though, there may be one reason why wearing dentures at night might be beneficial—it may help prevent obstructive sleep apnea. If you have this condition, talk to your dentist about whether wearing your dentures at night has more advantages than disadvantages. And, if bone loss created by wearing dentures is a concern, it could be resolved by having implants support your dentures. Again, discuss this with your dentist.
Taking care of your dentures will help increase their life and fit, and protect your health. And part of that may be taking them out to give your gums a rest while you’re resting.

Osteoporosis is a major health condition affecting millions of people, mostly women over 50. The disease weakens bone strength to the point that a minor fall or even coughing can result in broken bones. And, in an effort to treat it, some patients might find themselves at higher risk of complications during invasive dental procedures.
Over the years a number of drugs have been used to slow the disease’s progression and help the bone resist fracturing. Two of the most common kinds are bisphosphonates (Fosamax) and RANKL inhibitors (Prolia). They work by eliminating certain bone cells called osteoclasts, which normally break down and eliminate older bone cells to make way for newer cells created by osteoblasts.
By reducing the osteoclast cells, older bone cells live longer, which can reduce the weakening of the bone short-term. But these older cells, which normally wouldn’t survive as long, tend to become brittle and fragile after a few years of taking these drugs.
This may even cause the bone itself to begin dying, a relatively rare condition called osteonecrosis. Besides the femur in the leg, the bone most susceptible to osteonecrosis is the jawbone. This could create complications during oral procedures like jaw surgery or tooth extractions.
For this reason, doctors recommend reevaluating the need for these types of medications after 3-5 years. Dentists further recommend, in conjunction with the physician treating osteoporosis, that a patient take a “drug holiday” from either of these two medications for several months before and after any planned oral surgery or invasive dental procedure.
If you have osteoporosis, you may also want to consider alternatives to bisphosphonates and RANKL inhibitors. New drugs like raloxifene (which may also decrease the risk of breast cancer) and teriparatide work differently than the two more common drugs and may avoid their side effects. Taking supplements of Vitamin D and calcium may also improve bone health. If your physician still recommends bisphosphonates, you might discuss newer versions of the drugs that pose less risk of osteonecrosis.
Managing osteoporosis is often a balancing act between alleviating symptoms of the disease and protecting other aspects of your health. Finding that balance may help you avoid future problems, especially to your dental health.
