Gone are the days of dental air polisher clunky systems that created an unnecessary mess, clogging easily and sending patients into full complaint mode about the salty taste and unpleasant overspray, air polishing is not what it used to be.

New systems and materials on the market mean that air polishing is now an accessible and pleasant option for more patients than ever before. Dentists have been air polishing on a selective, but routine basis for over 20 years, and have seen first hand that modern air polishing helps make their practice more efficient, and is gentler and more comfortable for patients.

Air polishing units typically generate a stream of pressurized air, carrying specially graded particles of a mild soluble abrasive, such as sodium bicarbonate. The abrasive is directed, in the presence of a stream of water, at a tooth surface to be cleaned. The mixture of water and powderladed stream occurs on the tooth surface and forms a “slurry” that is responsible for the cleaning action.

Recent developments have brought new options to the market, including glycine, erythritol, calcium sodium phosphosilicate, calcium carbonate, and aluminum trihydroxide (to name a few). It's not necessary to review each in detail, but it's important that hygienists are generally educated on the many options now available for use.

In addition to being less restrictive when it comes to pre-existing patient conditions, two powders can now be used safely in subgingival air polishing: erythritol and glycine. Air polishing has traditionally been thought of as a technique for supragingival plaque and stain removal only; but these new options open the door for effective removal of subgingival plaque and biofilm, even in deep periodontal pockets.

Some current handheld air polishing devices connect directly to your dental handpiece tubing. Activation of the unit’s foot control generates the water and air supplies for the device. These “pencil-type” devices are of limited use in a busy hygiene office, but can be easily transported between operatories, conveniently stored, and can be ready for action on short notice.
