A dental bite block assembly includes a U-shaped mounting base having an upper bite portion, a lower bite portion, a central portion, an accessory mount, and a first magnetically energetic material embedded in the central portion of the U-shaped mounting base proximate the accessory mount. A dental accessory has a dental bite block mount that is detachably coupled with the accessory mount of the U-shaped mounting base and a second magnetically energetic material disposed in the dental accessory proximate the dental bite block mount. When the dental bite block mount is coupled with the accessory mount, the first magnetically energetic material embedded in the central portion of the U-shaped mounting base and the second magnetically energetic material disposed in the dental accessory are in operable magnetic engagement with each other.
