Pocket Reduction Walled Lake, MI Dentist Pocket reduction surgery treats the deep gum pockets that form at the edge of the gumline. These pockets can be difficult or impossible to effectively clean at home. With pocket reduction, these pockets are opened, thoroughly cleaned, then put back in place in a position that greatly reduces their depth. By minimizing the depth of the gum pockets, we can ensure that you will be able to avoid excessive bacterial growth in your gums by maintaining proper oral hygiene habits at home.
