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.

Chipped a tooth? Don't beat yourself up—this type of dental injury is quite common. In fact, you probably have a favorite celebrity who has chipped one or more of their teeth. The list is fairly long.
Some chipped a tooth away from the limelight, such as Tom Cruise (a hockey puck to the face as a teen), Jim Carrey (roughhousing on the playground) and Paul McCartney (a sudden stop with a moped). Others, though, chipped a tooth while “on the job.” Taylor Swift, Hillary Duff and Jennifer Lopez have all chipped a tooth on stage with a microphone. And chipped teeth seem to be an occupational hazard among professional athletes like former NFL star, Jerry Rice.
Since smiles are an indispensable asset to high-profile celebrities, you can be sure these stars have had those chipped teeth restored. The good news is the same procedures they've undergone are readily available for anyone. The two most common restorations for chipped teeth are dental bonding and veneers.
The least invasive way to fix a chipped tooth is bonding with a material known as composite resin. With this technique, resin is first mixed to match the tooth color and then applied to the chipped area or applied in layers of color to get just the right look. After a bit of shaping, curing and adjustment, we're done—you can walk out with a restored tooth in one visit.
Bonding works well with slight to moderate chips, but it could be less durable when there is more extensive damage. For that, you may want to consider porcelain veneers. Veneers are thin wafers of dental porcelain that are bonded to the front of teeth to mask blemishes like stains, slight gaps or, yes, chips. Veneers can be so lifelike that you won't be able to tell the veneered tooth from your other teeth. They are fashioned to match the color and shape of an individual's teeth. Because of the time and design detail involved, veneers are more expensive than bonding, yet still within an affordable range for many.
Teeth require some alteration before applying traditional veneers because otherwise the teeth can appear bulky when the veneer is bonded to the existing tooth. To compensate, we remove a little of the tooth enamel. Because this loss is permanent, you'll need to wear veneers or have some other form of restoration for the tooth from then on. For many people, though, that's a small price to pay for a smile without chips.
Your first step to repairing a chipped tooth is to come in for an examination. From there, we'll recommend the best option for your situation. And regardless of which, bonding or veneers, we can change your smile for the better.

Like the rest of healthcare, antibiotics have transformed dentistry. Advanced oral infections that once eluded successful treatment are routinely stopped with the use of these “wonder drugs.” But their overuse over the years has given rise to dangerous “superbugs” resistant to many antibiotics.
Antibiotics are one of the 20th Century's most significant healthcare achievements. Drugs like penicillin played a major role ending the global threat of tuberculosis, cholera and bacterial meningitis. Over the last few decades, more antibiotics have been developed to defend against an even wider array of bacterial dangers.
But along the way doctors and dentists began prescribing antibiotics for all manner of illnesses including viral infections like colds or flu for which they're less effective. They've also been increasingly used as a preventive measure, including inclusion in animal feed to fight disease.
But our tiny biological nemeses are adaptable. As bacterial strains come in contact with greater amounts of antibiotics, individual bacterium that survive transmit their resistance to subsequent generations. This can produce new strains like Staphylococcus aureus (MRSA) that are resistant to methicillin and other common antibiotics that once contained them.
There's deep concern that these new resistant strains, often recent incarnations of old diseases once thought defeated, will lead to higher rates of sickness and death. Increasing resistance could also make common procedures like those performed by dentists and oral surgeons, much riskier to undertake.
To combat this, pharmaceutical companies are racing to create new drugs to compensate. Recently, they've received an encouraging sign of hope in this battle from an unlikely source: viruses. Researchers in Tel Aviv, Israel have discovered an antagonistic protein to bacteria among a group of viruses called bacteriophages. The protein, injected into a bacterium, commandeers the cell's DNA function to aid virus reproduction, which kills the host.
In the words of one researcher, this makes these particular “enemy of our enemy” viruses our “friend.” Although the discovery is still a long way from practical use in antibiotics, harnessing it in future drug versions could help pack a greater punch against resistant bacteria.
In the meantime, providers and patients alike must practice and advocate for stricter protocols regarding the use of antibiotics. The viability of tomorrow's healthcare is on the line.
