Technique tips: microabrasion

Enamel defects are relatively common in anterior teeth and may cause aesthetic concern for a patient. They can present as white, yellow-brown or brown opacities. These opacities can have a profound effect on patients' self-esteem and confidence.

Microabrasion is a conservative, non-restorative method to remove this discoloration. It is often the treatment of choice, especially for brown opacities, as it is a simple yet effective technique.

If the stains are present in the outer layers of enamel they can be easily removed using microabrasion, leaving a smooth, glassy enamel surface as the finished result (Figures 1 and 2).

If there is an area of discoloration which is deep, this technique may need to be used in conjunction with tooth whitening or composite restorations.¹

It is important to ensure that patients are aware that microabrasion is not always successful.

Clinical photographs and sensibility testing are recommended prior to commencing microabrasion to form baseline records. This should be repeated after the procedure.
