After a long struggle with dental disease, you have finally lost the last of your remaining teeth.Â Like over a quarter of Americans in their 60s and 70s, this unfortunate development can have a profound impact on your health and self-image.
While there are a number of advanced methods for replacing lost teeth, there's one tried and true option that's centuries old — the removable denture. It's the option millions of people have chosen to lessen the impact of missing teeth.
Fashioned properly, removable dentures restore the form and function you once had with your natural teeth. The prosthetic (false) teeth are precisely placed in an acrylic, gum-colored base that closely follows the contours of your gums. Because they're removable, they're fairly easy to clean and maintain.
They do have a disadvantage, though, and it's related to bone health after tooth loss. Like other living tissues, bone has a life cycle: as older cells die, new cells form to take their place. The forces your teeth generate when you chew stimulate new bone growth. But without teeth to provide this stimulation, new bone won't keep up the pace of replacement at a healthy rate. As a result you may gradually lose bone, as much as a quarter of its normal width within a year of losing a tooth.
Dentures don't transmit any stimulation to the gum and bone from chewing. Furthermore, the compressive forces transmitted to the gum and underlying bone tissue contributes to bone loss. As the bone continues to diminish, your denture fit becomes looser to the point you will eventually need them relined with new acrylic material or have a new set made.
There is another alternative when patients loose all of their teeth: an implant-supported removable denture. Dental implants can be used to keep the dentures more secure and can also slow or even halt bone loss where the implants are placed. In this case we strategically place a few implants to serve as supports for a removable denture. The denture has connection points that join up with the implants to hold it more securely in place. As few as two implants are needed in the lower jaw, while the upper jaw does better with three or four implants.
Losing all your teeth can be traumatic, but there are effective ways to overcome it. With new technology, the traditional restoration of removable dentures may be the vehicle for achieving that.

You might think David Copperfield leads a charmed life:Â He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.
“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”
Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?
In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.
There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.Â Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.

Dental fillings are the most common dental procedure. However, choosing the right type of filling for you and your teeth can be confusing. Thankfully, you can learn more about this important and necessary dental procedure with help from Dr. Ashley Lloyd in Raleigh, NC.
When is a filling necessary?
When decay forms on a tooth, the required treatment involves removing the decay before it eats its way further into the tooth. More severe cases of tooth decay require more of the tooth’s structure to be removed, leaving behind a hole in the tooth. Dental fillings fill the hole and seal off the tooth, preventing future problems. Most filling procedures last about an hour and, thanks to local anesthetic, are painless.
Types of Dental Fillings
- Porcelain: Porcelain fillings are tooth-colored and stain-resistant. However, porcelain fillings are more expensive than other types of fillings.
- Composite Resin: Composite resin fillings are most commonly used as they are more affordable than other options and come in various shades of tooth-colored materials. These fillings blend into the teeth and provide a more natural appearance than metal fillings.

The procedure for dental fillings begins with numbing the work area with local anesthetic. With the area numb, your dentist removes the decayed portion of the tooth, then cleans and disinfects it. Your dentist uses your choice of filling material to fill the tooth. Depending on the material, this could involve molding the composite resin directly onto the tooth and hardening it with a special light. A dental laboratory creates metal and porcelain fillings, which your dentist bonds to the tooth using dental adhesive.

Your tooth is in peril if its innermost layer, the pulp, becomes infected and inflamed. Deep tooth decay, repeated dental procedures or fractures can all expose the pulp and ultimately the roots to infection and lead to tooth loss.
But that scenario isn't inevitable — we can often save the tooth with a root canal treatment. By accessing the tooth's interior through a prepared hole, we're able to clean out the infected tissue in the pulp chamber and root canals, and fill the empty space with a special filling. We then cap the tooth with a custom crown to protect it from a re-infection.
Root canal treatments have a very high success rate — chances are good your tooth will survive for many years afterward. But there's a slight chance the tooth may become re-infected; in that case, a second root canal treatment may be in order.
In a few cases, though, a second root canal may not be advisable, and could even accelerate damage to the tooth. For example, if past dental work resulted in an extensive crown restoration, accessing the root canals the conventional way will require disassembling that restoration. This could weaken the tooth significantly.
We can approach the problem from a different route: instead of accessing the tooth's interior through the crown (the visible part of the tooth), we instead perform a surgical procedure called an apicoectomy, which accesses the tooth at the root end through the gums.
In this procedure we numb the area with local anesthesia and then make a small incision through the gums at the level of the affected root. After access, we remove any diseased tissue around the root and a few millimeters of the root tip itself. We then insert a small filling in its place to seal the canal and prevent further infection. In some cases we may also insert a graft to encourage bone growth and aid in healing.
Over time, the affected area will heal and return to normal function. Even if a traditional root canal treatment can't be used, an apicoectomy could be another option for saving your tooth.
