Abstract: A dental instrument silencer assembly for reducing noise from a dental instrument includes a silencer that may have a dental instrument extended therethrough. The silencer is gripped for manipulating the dental instrument. Moreover, the silencer is comprised of an acoustically insulating material to reduce noise produced by the dental instrument when the dental instrument is turned on. A first cap is removably coupled to the silencer to frictionally engage the dental instrument. The first cap is comprised of a resiliently compressible material to absorb vibration from the dental instrument when the dental instrument is turned on. A second cap is removably coupled to the silencer to retain the dental instrument in the silencer.
