As with any health care field, dentistry constantly evolves. From new and improved treatment plans to high-tech tools in dentists' offices, today's patients receive the highest level of care. Air abrasion, otherwise known as intraoral sandblasting, is a recently developed technique that you may encounter in your future visits to the dentist.
"Air abrasion blasts away decay."
What is air abrasion?
Air abrasion provides an alternative to the typical drilling method of removing tooth decay. When filling a cavity, the dentist normally uses a drill to reach the affected area and remove all bacteria. The air abrasion technique essentially does the same job as the drill, just in a different way. Instead of sending a spinning file to the tooth's surface, air abrasion blows air filled with aluminum oxide particles at the tooth to blast away decay and small portions of the tooth's structure, according to the Academy of General Dentistry.
Air abrasion is sometimes called intraoral sandblasting because of the similarities between the two processes. Sandblasting strips and smooths surface or imprint designs. For instance, sandblasting may be used to remove graffiti from a wall. Air abrasion does not use sand, but the same concept applies: air-streamed abrasives remove material off the surface of the tooth.
What is it used for?
Dentists may use air abrasion for many of the same procedures that require a drill. According to a study published in the Journal of Conservative Dentistry, this includes removing enamel defects, detecting and treating cavities, preparing the teeth for veneers and getting rid of old fillings. Dental health professionals may also use the technique to fix small chips in the tooth.
Is air abrasion better than drilling?
While air abrasion and drilling have similar characteristics, the newer technique can't replace all drilling procedures. For instance, dentists still typically prefer to use drilling for deep cavities, though they may opt for air abrasion for less severe decay.
That being said, air abrasion does hold certain advantages. For example, while your dental team will use a combination of gel and local anesthesia to take away the pain factor when filling cavities with a drill, all those numbing tools may not be necessary with air abrasion. Additionally, air abrasion doesn't have that same - sometimes dreadful - buzzing sound of the drill, and it provides a more gentle approach.
Talk to your dentist about your treatment options. New technology is always emerging or at least underway, and your dental health team may have more tools at their disposal than you realize.
