A dental gutter is a removable dental appliance that conforms to the shape of the teeth. It is designed from a teeth impression and looks like a kind of mouthguard. There are different types of gutters. The occlusal gutter corrects jaw disorders and temporomandibular joint (TMJ) disorders related to involuntary jaw muscle contractions. It is this type of gutter that is used in particular in the case of bruxism. The orthodontic gutter is used to correct dental malpositions. It allows the teeth to move smoothly. The major advantage of these gutters is their discretion and ease of maintenance compared to the brackets.
