Drilling teeth is an essential part of repairing and restoring the damage caused by tooth decay. For generations dentists have relied on the dental drill with its rotating burr to remove decayed and damaged tooth material.
But while the dental drill is effective it also has its disadvantages. In the process of removing decayed material it inadvertently removes healthy structure near the target material. It often requires anesthesia to deaden the work area. And its noise and vibration are often unsettling to patients.
There is a growing alternative, though: air abrasion, a technology that's been around since the mid-20th Century. But recent advances in controlling the dust created by using abrasion, as well as new tooth-colored bonding materials to replace tooth structure, have sparked new interest among dentists and patients alike.
Also known as particle abrasion, this drill alternative uses a pressurized stream of fine particles to remove decayed material. Using a hand wand a dentist can precisely aim the stream of particles (usually aluminum oxide) to the specific areas of decay or softened material that need to be removed. As a result, it removes only a fraction of healthy tooth structure compared to traditional drilling. Air abrasion has also proven effective for removing staining without harming enamel.
Air abrasion also eliminates the sound and vibration associated with dental drills, and may not always require local anesthesia. On the other hand, it does have some limitations. For one, it's not as effective with larger cavities or working around older fillings. The tooth or teeth to be worked on must be carefully isolated from the rest of the mouth to keep the patient from swallowing the abrasive particles. And without a high-volume suction pump and good isolation protocols, the particles can produce something of a “sandstorm” in the treatment room.
But as air abrasion continues to advance, we may see improvements in these limitations. In a future time, the traditional dental drill may go the way of the horse and buggy.

So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.

If you have chronic jaw joint pain you may have heard of using Botox to relieve discomfort from temporomandibular disorders (TMD). Before you seek out this remedy, though, be sure you know the facts beforehand.
TMD is actually a group of conditions affecting the joints, muscles and overall structures of the jaw. People with TMD often experience sharp pain and reduced range of motion of the jaw joints. Although we don't know the exact causes, we believe stress (accompanied often by teeth grinding habits) is a major factor for many patients.
Treatments run the spectrum from conservative to aggressive. Conservative treatments include cold and heat packs, therapeutic exercises, and muscle pain or relaxant medication. On the more aggressive side, patients undergo surgery to reorient the lower jaw. Most people gain a significant amount of relief from conservative therapies; the results aren't as positive with surgery.
Botox falls on the aggressive side of treatments. Approved for use by the Food and Drug Administration for cosmetic uses, the drug contains botulinum toxin type A, a bacterial toxin that can cause muscle paralysis. It's often injected into facial structures to paralyze small muscles and temporarily “smooth out” wrinkle lines. Only recently has it been proposed to help relieve jaw pain.
The jury, however, is still out on its effectiveness with jaw pain. The double-blind testing performed thus far hasn't produced any relevant clinical results that the injections actually work with TMD.
And there are other complications. Some people injected with Botox encounter pain, bruising or swelling at the injection site, and some have severe headaches afterward. Botox is also a temporary solution, not a permanent cure — you'll need another injection a few months later to maintain the effect. You might even develop antibodies that diminish the drug's effect and require higher subsequent doses to compensate.
This and other concerns should give you pause before seeking out this remedy. The best strategy is to try the traditional treatments first, which are also the least invasive. If there's no significant relief, then talk to us and your physician about other options.
