This is a very effective way of removing stains from your teeth, whether used alone or in combination with bleaching or bonding and can give dramatic results.
Why use micro-abrasion?
There are many reasons why teeth may become stained – through antibiotic use, from orthodontic brackets or bands, and various other reasons. If the stains are in the outer layers of enamel, they can be successfully removed, leaving a smooth, glassy enamel surface. Interestingly, the abraded surface has been demonstrated to be more resistant to cavities that the original tooth surface.
What does the process involve?
The teeth being treated must be first isolated with a rubber dam to protect the gums from coming into contact with the acid. The pumice-acid paste is then applied to the tooth or teeth and rubbed either manually or with a very slow speed rotary action. After a few layers of enamel are removed, the paste is rinsed with water and the results evaluated.
This process is repeated until the stain is gone or until the enamel is getting too thin. After the process is finished, the teeth are usually bathed in a fluoride gel in order to reduce any sensitivity that may be experienced and then the rubber dam is removed. The entire process takes less than an hour and is permanent.
