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.

While it may not be one of your favorite features in the dental office, the dental drill is nevertheless necessary for treating problem teeth. It’s used primarily for removing decayed or damaged structure and preparing a tooth for fillings or other restorations.
Dental drills have been used for decades and are quite effective — but they have their drawbacks. Their rotating burrs often remove portions of healthy tooth structure along with decayed material. Friction from the drill action can cause discomfort, so local anesthesia is usually needed. Drills can also emit a high-pitched machine noise that’s unsettling to many patients.
There’s a growing alternative to the drill, known as air abrasion. Although the technology has been around since the 1950s, the development of new suction pumps that capture the resulting dust from its use has made it more palatable as an option to the traditional drill.
Also known as particle abrasion, the technique uses a pressurized stream of fine particles (usually aluminum oxide, an abrasive powder) directed at teeth to wear away (abrade) the tooth’s structural surface. We can be quite precise in the amount of surface material removed, so it’s useful for diminishing stains or roughing the surface for bonding materials like composite resin. We’re also able to remove decayed material with very little impact on surrounding healthy structure, and you may not need anesthesia during the procedure.
While this quiet alternative to the noisier drill is quite versatile, it does have its limitations. It’s not that efficient for preparing larger cavities for restoration or for removing older amalgam fillings. The teeth to be treated must be carefully isolated to prevent the fine particle dust produced from being swallowed by the patient or spread into the air. High-volume suction equipment is a must or the procedure will create a “sandstorm” of particles in the room.
Still, for situations suited to it and with proper isolation measures, air abrasion can be effective and comfortable. If the technology continues to improve, the dental drill may soon become a relic of the past.
