It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

Unless you're 6 years old and on speed dial with the Tooth Fairy, a loose tooth isn't a good feeling. It's also a sign something is wrong in your mouth. If you don't take prompt action, you may lose that tooth for good.
To begin with, teeth are held in place by an elastic tissue known as the periodontal ligament. The ligament lies between the tooth and bone and attaches to both through tiny fibers. The thing to note about the ligament is that it does allow for tooth movement, which serves as a “shock absorber” against the forces generated while biting and chewing.
But that movement is normally so slight, you won't perceive it. If you do, chances are there's a problem with the ligament attachment, which may have been damaged due to trauma or disease.
A hard blow to the face could certainly damage both the teeth and their attachments. But it can also happen if one tooth extends out farther than the rest and absorbs more stress during chewing. You could encounter similar damage if you attempt DIY orthodontics or wear tongue jewelry.
The more common source of ligament damage, though, is periodontal (gum) disease, usually caused by dental plaque, a thin film of bacteria and food particles left on tooth surfaces. If not treated, the infection can advance deeper into the gum tissues (and eventually the supporting bone), causing the ligaments to weaken and detach. In fact, a loose tooth is often a sign of well-advanced gum disease.
If you notice a loose tooth, you should make an appointment with us as soon as possible. Our first step is to ascertain the underlying cause and initiate any needed treatment. We may also want to splint a loose tooth to adjacent teeth to prevent excessive movement while the ligaments heal and reform their attachment to the tooth.
There will be times when a loose tooth is beyond repair. In that case, it may be best to remove the tooth and install a life-like replacement like a dental implant. But that's not inevitable. If at all possible and practical, we'll try to save your loose tooth.

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.
