Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.
But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.
This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.
This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.
But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.
Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.
Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

Osteoporosis is a serious bone weakening disease in older adults that can turn a minor fall into a major bone fracture. But the condition could also impact dental treatment—triggered ironically by the drugs used to treat osteoporosis rather than the disease itself.
From the Latin for “porous bone,” osteoporosis causes bone to gradually lose mineral structure. Over time the naturally-occurring spaces between mineralized portions of the bone enlarge, leaving it weaker as a result.
Although there's no definitive cure for osteoporosis, a number of drugs developed over the last couple of decades can inhibit its progress. Most fall into two major categories, bisphosphonates and RANKL inhibitors.
These drugs work by inhibiting the normal growth cycle of bone. Living bone constantly changes as cells called osteoblasts produce new bone. A different type, osteoclasts, clear away older bone to make room for these newer cells. The drugs selectively destroy osteoclasts so that the older bone, which would have been removed by them, remains for a longer period of time.
Retaining older cells longer initially slows the disease process. But there is a downside: in time, this older bone kept in place continues to weaken and lose vitality. In rare instances it may eventually become detached from its blood supply and die, resulting in what is known as osteonecrosis.
Osteonecrosis mostly affects two particular bones in the body: the femur (the long bone in the upper leg) and the jawbone. In regard to the latter, even the stress of chewing could cause osteonecrosis in someone being treated for osteoporosis. It can also occur after tooth extractions or similar invasive procedures.
If you're taking a bisphosphonate or RANKL inhibitor, you'll want to inform your dentist so that the necessary precautions can be taken before undergoing dental work more invasive than routine cleanings or getting a filling or crown. If you need major dental work, your dentist or you will also need to speak with your physician about stopping the drug for a few months before and after a dental procedure to minimize the risk of osteonecrosis.
Fortunately, the risk for dental problems while undergoing treatment for osteoporosis is fairly low. Still, you'll want to be as prepared as possible so that the management of your osteoporosis doesn't harm your dental health.

We're all tempted occasionally to use our teeth in ways that might risk damage. Hopefully, though, you've never considered anything close to what singer, songwriter and now social media persona Jason Derulo recently tried in a TikTok video—attempting to eat corn on the cob spinning on a power drill. The end result seemed to be a couple of broken front teeth, although many of his followers suspected an elaborate prank.
Prank or not, subjecting your teeth to “motorized corn”—or a host of other less extreme actions or habits—is not a good thing, especially if you have veneers, crowns or other dental work. Although teeth can withstand a lot, they're not invincible.
Here, then, are four things you should do to help ensure your teeth stay healthy, functional and intact.
Clean your teeth daily. Strong teeth are healthy teeth, so you want to do all you can to prevent tooth decay or gum disease. Besides semi-annual dental cleanings, the most important thing you can do is to brush and floss your teeth daily. These hygiene tasks help remove dental plaque, a thin biofilm that is the biggest culprit in dental disease that could weaken teeth and make them more susceptible to injury.
Avoid biting on hard objects. Teeth's primary purpose is to break down food for digestion, not to break open nuts or perform similar tasks. You should also avoid habitual chewing on hard objects like pencils, nails or ice to relieve stress. And, you may need to be careful eating apples or other foods with hard surfaces if you have veneers or composite bonding on your teeth.
Wear a sports mouthguard. If you or a family member are regularly involved with sports like basketball, baseball/softball or football (even informally), you can protect your teeth from facial blows by wearing an athletic mouthguard. Although you can obtain a retail variety in most stores selling sporting goods, a custom-made guard by a dentist offers the best protection and comfort.
Visit your dentist regularly. As mentioned before, semi-annual dental cleanings help remove hidden plaque and tartar and further minimize your risk of disease. Regular dental visits also give us a chance to examine your mouth for any signs of decay or gum disease, and to check on your dental health overall. Optimizing your dental health plays a key part in preventing dental damage.
You should expect an unpleasant outcome involving your teeth with power tools. But a lot less could still damage them: To fully protect your dental health, be sure you practice daily oral care, avoid tooth contact with hard objects and wear a mouthguard for high-risk physical activities.
