Seven out of ten Americans are missing at least one tooth due to decay, periodontal (gum) disease or injury. Unfortunately, the consequences go far beyond a missing tooth — the loss of even one could set in motion a cascade of problems.
Perhaps the most damaging of these problems is bone loss. Like other living tissue, bone has a life cycle — older cells dissolve (resorb) into the body and are replaced by fresher cells. This growth cycle in the jawbone receives stimulation from forces generated by teeth when we chew or bite. If a tooth is no longer present to provide this stimulation, the affected bone cells won’t regenerate at a healthy rate. Over time this causes the volume of bone to diminish, as much as 25% the first year after tooth loss.
The void left by a missing tooth can also adversely affect remaining teeth. Teeth are held in place by a tough but elastic tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament enables teeth to move gradually in response to mouth changes so that the teeth remain tightly aligned with each other. When there’s a gap from a missing tooth, this tendency will cause the teeth on either side to move (or “drift”) toward the open space. Although a natural phenomena, it can result in a malocclusion (poor bite).
That’s why it’s important to replace a missing tooth with a life-like replica — not just for appearance’s sake, but also to improve function and prevent the rise of these other problems. While many options exist (from removable dentures to fixed bridges) the choice most preferred by dentists and patients is the dental implant.
An implant replaces the tooth root as well as the crown, because it’s imbedded securely into the jawbone. Because of a natural affinity with titanium, the principal metal used in implants, bone cells will grow to its surface. Not only will this anchor the implant more securely, it will slow or even stop bone loss.
If you have a missing tooth, you should visit us as soon as possible to consider your options for a replacement. A new tooth will help stop even greater problems from occurring.

To keep a healthy smile, brushing and flossing your teeth every day should be at the top of your to-do list, along with regular dental visits. Dental visits are usually scheduled every six months when your dental professional will remove any built-up plaque and tartar (hardened plaque deposits) missed during everyday hygiene.
If you've experienced periodontal (gum) disease, however, these dental visits may become even more important toward preventing a re-infection. For one thing, your dentist may want to see you more frequently.
Gum disease is caused by bacteria living in dental plaque, which first infect the superficial layers of gum tissue. Even though the body initiates an inflammatory response to fight it, the infection continues to grow as long as there is plaque present to fuel it. The problem isn't just plaque on the visible tooth surface—hidden plaque beneath the gum line can create deep pockets of infection that can be difficult to treat.
To stop the infection, dentists must manually remove plaque through procedures known as scaling and root planing. Any and all plaque and tartar deposits must be removed, even those deep around the roots, to arrest the infection. This often requires several treatment sessions and sometimes gum surgery to access areas below the gum line.
These types of treatments, especially in the disease's early stages, have a good chance of restoring health to your gums. But because of the high possibility of reinfection, your dentist will need to step up your regular dental maintenance from now on. This could mean visits as frequent as every few weeks, depending on your particular case of gum disease and your dentist's recommendation.
Your dental visits after gum disease may also become more involved than before. Your dentist will now monitor you closely for any signs of reinfection and at the first sign initiate a new round of treatment. You may also need surgical procedures to make some areas around your teeth more accessible for future cleaning and maintenance.
Periodontal maintenance after gum disease helps ensure another infection doesn't rise up to undermine your progress. To paraphrase a well-known quote, eternal vigilance is the price of continuing good dental health.
While braces are often the stars for straightening smiles, they're not the only cast members in an orthodontic production. Orthodontists occasionally turn to other appliances if the bite problem is challenging. Whatever the tool, though, they usually have something in common—they use the principle of anchorage.
To understand anchorage, let's first consider the classic kid's game Tug of War. With teams on either end of a rope, the object is to pull the opposing team across the center line before they pull you. To maximize your pulling force, the player at the back of your rope, usually your stoutest member, holds steady or "anchors" the rest of the team.
Like a Tug of War team, braces exert force against the teeth. This stimulates the supporting periodontal ligament to remodel itself and allow the teeth to move. The braces use the teeth they are attached to as anchors, which in a lot of cases are the back teeth. By attaching a thin wire to the brackets or braces on the teeth, the orthodontist includes all the teeth on the arch, from one end to the other. Anchored in place, the wire can maintain a constant pressure against the teeth to move them.
But not all bite situations are this straightforward. Sometimes an orthodontist needs to influence jaw growth in addition to teeth movement. For this purpose, they often use orthodontic headgear, which runs around the back of the head or neck and attaches to orthodontic brackets on the teeth. It still involves an anchor but in this case it's the patient's own skull.
In some situations, an orthodontist may feel he or she needs more anchorage as the teeth alone may not be enough. For this, they might establish a separate or additional anchor point using a temporary anchorage device (TAD). A TAD resembles a tiny screw that's inserted into the jawbone near the tooth intended for movement. The orthodontist can then attach the TAD to braces hardware using some form of elastics. After treatment, they remove the TAD.
These are just a couple examples of specialized tools an orthodontist can use for bite correction. Thanks to them and similar devices, even the most complex bite problem can be overcome to create a healthier and more attractive smile.
