Also known as interproximal reduction (IPR), it is a time-tested process that has been utilized for over a century and offers numerous benefits. As such, it is strongly encouraged by the American Association of Orthodontists. Benefits include resolving crowding without expansion or extraction, closing gum-line spaces, decreasing food collection between teeth, and increasing tooth stability.
The rationale behind slenderizing is that each tooth has an excess of enamel. Minor removal of enamel across multiple teeth, according to the American American Association of Orthodontists, is a conservative, time-tested approach to resolving a variety of dental problems.
