Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

Dental implants are known for their durability as well as life-like beauty. Thanks to their unique construction and ability to integrate with bone, they have a very high success rate and can last for decades.
But while they’re less problematic than other restorations, we still can’t “set them and forget them.” While the implants themselves aren’t susceptible to disease, the supporting gums, bone and adjacent teeth are. If you want them to last as long as possible, you’ll need to care for them and the rest of your mouth through daily oral hygiene and semi-annual office cleanings.
With that said, there are a few differences in how we perform hygiene tasks with implants. This is due to the way in which they attach to the jaw, as the titanium post is inserted directly into the bone. Natural teeth, on the other hand, are held in place by the periodontal ligament, a strong connective tissue that lies between the teeth and bone. The ligament holds the teeth firmly in place while also allowing minute tooth movement in response to changes in the mouth.
The ligament also has an ample blood supply that assists with fighting infection that may arise in the tooth and its supporting gums. Without this extra source of defense, infections that arise around an implant can grow quickly into a condition known as peri-implantitis and lead to rapid bone loss that could cause the implant to fail.
That’s why you and your hygienist must be ever vigilant to the buildup of plaque, the bacterial film that gives rise to dental disease, around implants and adjacent teeth. This includes removing plaque buildup from implant surfaces, although your hygienist will use tools (scalers or curettes) made of plastic or resin rather than traditional metal to avoid scratching the implant’s dental material. They’ll likewise use nylon or plastic tips with ultrasonic equipment (which uses high vibration to loosen plaque) and lower power settings with water irrigation devices.
Keeping infection at bay with effective hygiene is the number one maintenance goal with dental implants. Doing your part along with your hygienist will help you get the most of this investment in your smile.

The next time you visit your dentist you might see an item quite different from the other dental instruments and equipment in the office: a blood pressure cuff. Checking blood pressure is becoming a more common occurrence in dental offices across the country.
Abnormal blood pressure and some of the medications used to treat it are often a factor in some dental procedures, particularly if anesthesia is involved. But your dentist may also check your blood pressure for another reason: dental visits represent another avenue to screen for this condition that increases the risk of serious health problems.
Undiagnosed high blood pressure is a prevalent but often “silent” problem because the early stages of the condition may not display any symptoms. Many people first become aware they have an issue only after a blood pressure check at their family doctor, pharmacy or a health fair, for example. Otherwise, they could go months, even years without this vital knowledge about their health.
But while people may only visit their doctor once a year (or less) many see their dentist much more often, even twice a year, for routine cleanings and checkups. Including blood pressure screenings as a routine part of dental treatment could alert patients to a potential issue much earlier than their next doctor’s visit.
In fact, one study published in the Journal of the American Dental Association looked at a group of dental patients with no reported heart disease risk and who had not seen a doctor in the twelve months before their dental visit. During their visit their blood pressure was checked. Of those then referred to a physician for an abnormal reading, 17% learned for the first time they had an increased risk of cardiovascular disease.
It’s estimated about 80 million Americans have some form of cardiovascular disease and many don’t even know it. Diagnosing and controlling high blood pressure is a key factor in treating these life-threatening conditions. And many dentists are joining the fight by making this simple screening method a part of their dental care services.
