Imagine not having your upper teeth for talking and eating, not to mention your appearance, and you’ll have some idea of what Beauty the bald eagle experienced after losing the top of her beak to a hunter’s bullet in northern Idaho. She couldn’t groom or feed herself and could barely drink water, relying instead on the conservation group that had taken her under their wing for assistance. But the magnificent raptor was eventually made whole and able once again to eat, drink and preen unaided. It took a visionary mechanical engineer and a very skillful dentist who designed and attached the first-of-its-kind bald eagle “dental” prosthetic — dubbed the “bionic beak.”
Prosthetic Teeth for Humans
Fortunately, the field of human prosthetic dentistry (or prosthodontics) is much more advanced than it is for our avian friends. We have several options for replacing missing teeth (as well as parts of missing teeth) that restore aesthetic appearance and functionality while potentially preventing other problems such as the drifting out of alignment or loss of remaining teeth.
Bridges. As the name suggests, these custom-made devices span the area that is missing a tooth/teeth. Fixed (not removable) bridges are made up of an artificial tooth/teeth fused between two crowns that fit over your existing teeth or dental implants (see below) on either side of the gap. There are removable bridges, but they are considered temporary fixes.
Dentures. These are custom-made removable replacements for missing teeth. Partial dentures offer a removable alternative to fixed bridges and are used when some teeth are missing in an upper or lower arch (jaw). Full dentures are used when all teeth are missing in an arch. Replacement teeth are embedded in an acrylic base that fits over your gums and mimics their color.
Dental Implants. These are the closest thing to having your own tooth/teeth back. An implant is a small titanium post that is placed in the jawbone beneath the gum to serve the same purpose as a tooth root. Once the bone joins to the implant (a process called osseo-integration), a lifelike crown is attached to it.
We would be glad to discuss which option would be right for you.

For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.

Determining which of your teeth is causing your toothache isn’t always easy — or even if it’s a tooth at all. The pain could be coming from a tooth, the gums, or both. Only a thorough dental examination can pinpoint the exact cause and best course of treatment.
If a decayed tooth is the problem, the pain may be coming from nerves and other tissue deep within the tooth’s pulp. The symptoms could be dull or sharp, constant or intermittent, specific to one area or spread out. It’s even possible for the pain to suddenly subside after a few days. This doesn’t mean the infection has subsided, but rather that the infected nerves have died and no longer transmit pain. Pain can also radiate from the actual source and be felt somewhere else — the pain in your sinuses, for example, could actually originate from an infected back tooth.
If the source is periodontal (gum) disease, the infection has begun in the gum tissues. As they become more inflamed they lose their connectivity with the teeth, bone loss occurs and the gums may “recess” or draw back. This exposes the tooth root, which without the protective cover of the gum tissues becomes highly sensitive to changes in temperature or pressure. As a result you may encounter sharp pain when you eat or drink something hot or cold, or bite down.
Treating these issues will depend on the actual infection source. An infected tooth often requires a root canal treatment to clean out the pulp and root canals of dead or infected tissue, fill them with a special filling, and seal and crown the tooth to prevent future infection. If the source is gum disease, we must manually remove the bacterial plaque causing the disease from all tooth and gum surfaces to stop the infection and allow the gums to heal. In advanced cases, surgical procedures may be necessary to repair damage and encourage new gum and bone growth.
Where dental disease has spread from tooth to gums or vice-versa, you may need treatments for both areas to address your overall condition. Whatever the treatment course, we can put an end to your tooth pain and restore health to your teeth and gums.

“You need a root canal,” isn’t something you want to hear during a dental visit. But whatever your preconceptions about it may be, the fact is root canal treatments don’t cause pain — they alleviate it. What’s more, it may be your best chance to save a tooth that’s at high risk for loss.
First of all, root canal treatments address a serious problem that may be occurring inside a tooth — tooth decay that’s infiltrated the pulp chamber. If it’s not stopped, the decay will continue to advance through the root canals to the bone and weaken the tooth’s attachment. To access the pulp and root canals we first administer a local anesthesia and then create an opening in the tooth, typically in the biting surface.
After accessing the pulp chamber, we then remove all the pulp tissue and clean out any infection. Â We then fill the empty pulp chamber and root canals with a special filling and seal the opening we first created. The procedure is often followed some weeks later with a laboratory made crown that permanently covers the tooth for extra protection against another occurrence of decay and protects the tooth from fracturing years later.
Besides stopping the infection from continuing beyond the roots and saving the tooth from loss, root canal treatments also alleviate the symptoms caused by decay, including tenderness and swelling of surrounding gum tissue and sensitivity to hot and cold foods or pressure when biting down. And, it reduces pain — the dull ache or sometimes acute pain from the tooth that may have brought you to our office in the first place.
General dentists commonly perform root canal treatments; in more complicated cases they’re performed by an endodontist, a specialist in root canal treatments. Afterward, any discomfort is usually managed with non-steroidal anti-inflammatory drugs (NSAID) such as ibuprofen or aspirin.
Root canal treatments are a common procedure with a high rate of success. Undergoing one will end the pain and discomfort your infected tooth has caused you; more importantly, your tooth will gain a new lease on life.

Dental implants are popular with both patients and dentists for their durability and likeness to natural teeth. That natural look, though, can be difficult to attain, especially in what’s known as the “smile zone” — the area of the mouth where teeth are most visible when you smile.
Our biggest concern is the upper front teeth, where the gums are most visible, especially if you smile widely. It takes considerable skill, experience and artistry to position implants in this area so that they appear to naturally emerge from the gums and blend well with other teeth.
To obtain that natural look, we must first assess whether or not there’s enough bone present, which tends to dissolve (resorb) when a tooth is missing, to sufficiently anchor the implant in the right position. There also needs to be sufficient bone around adjacent teeth to support the tiny triangles of gum tissue between teeth called papillae. Without the papillae an unattractive black hole may result between the implant and an adjacent tooth or implant.
Another factor we must consider is the type of gum tissue you have. Everyone generally inherits one of two types of tissue from their parents: thin or thick. The type you have can influence the way the implant appears to emerge from the gums. If you have thick gums, they’re easier to work with and can cover more of the implant. Thinner tissues aren’t quite as easy and are less forgiving if an implant isn’t placed as precisely as possible.
In recent years, improvements in implant design have sought to provide greater stability around bone and gum tissues to offset some of the issues we’ve mentioned. A variation on the design of the top of the implant (where the crown is attached) changes the direction of growth for gum tissues from a horizontal orientation to a vertical one, which can help with the final appearance.
The first step, if you’re considering dental implants for a tooth in the smile zone, is to visit us for a complete examination to see if any of these factors may have an impact on your situation. We can then advise you on the best course of action to achieve the most attractive smile possible.
