A fair number of people with total tooth loss have arrived at this point after a long history of dental issues. It's quite likely they've had a series of bridges or partial dentures over the years to accommodate lost teeth at various times before moving to full dentures.
For many, it often seems easier to extract any remaining teeth at some point and simply move on to a total restoration. It's often better for oral health, however, to preserve any remaining teeth for as long as possible and update restorations as needed. Dental implants could make this type of staged restoration strategy much easier to manage.
Implants are tiny metal posts surgically imbedded in a patient's jawbone. Over time, bone cells grow and adhere to the implant's titanium surface, creating a strong and durable hold. Its most familiar application is as a replacement for an individual tooth.
But because of their strength and durability, this advanced dental technology is also used to support other restorations like bridges and partial or full dentures by way of a few strategically placed implants. And it's in that role that they can be useful in planning and implementing future restoration upgrades when needed.
Under this strategy, we add implants to supplement pre-existing implants from earlier restorations to support the updated dental work. For example, we might have previously placed an implant supporting a single tooth or a small bridge. When the need later arises for a partial denture, we can add additional implants to be used with the earlier one to support the new denture.
If the earlier implants have been well-placed, we need only to add enough implants necessary to support a full denture when the time comes. How many will depend on the particular type of denture: A removable lower denture may only require one additional implant with one already in place. A fixed upper or lower denture will require enough to bring the number to between four and eight.
Taking this long-term approach can be more cost-effective in the long-run. More importantly, it can make for a smoother path for the patient and help preserve remaining teeth for as long as possible.

As far as your appearance goes, the most important teeth you have are those in the “smile zone.” These are the teeth most visible when you smile—and the ones that awkwardly stand out if they're chipped, worn or otherwise flawed. More than any other teeth, they determine how inviting your smile is to others.
You might think you'll need extensive cosmetic dental work to fix these kinds of dental defects. But that may not be necessary: We may be able to use a dental material known as composite resin to repair the defects in your “smile zone” teeth in one office visit.
Composite resins are a combination of ceramics and plastics that have been around for some time. They've only recently come into wide use, though, with the development of new techniques to bond them to tooth surfaces. They're ideal for chips, cracks, or decayed areas where front teeth make contact with one another. They may also be used occasionally to reshape irregular or misaligned teeth.
You'll first need a complete dental examination to determine if composite resin bonding is an appropriate approach for your situation. If so, we'll begin by preparing the tooth surface to better accept the resin material. We'll then apply the liquid form of the material in layers, along with other agents to increase the material's strength. Each layer is cured (hardened) before applying the next layer.
As the layers build up, we shape the material to achieve a normal tooth appearance. We'll also incorporate your individual color shadings, so that the prepared tooth blends well with surrounding natural teeth. In effect, the procedure requires as much artistry as technical skill to create a natural look.
Though not as strong as porcelain veneers or crowns, composite resins are durable if not subjected to heavy biting forces. And for a few hours in the dentist's chair with minimal tooth preparation, a composite resin treatment can create a dramatic and exciting change in your appearance.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.
