This invention relates to dentistry, and more particularly to cosmetic dentistry, where for aesthetic objectives it is desirable to remove a small amount of the patient's tooth enamel to modify tooth color. A procedure is described using an applicator and compound which provides accelerated treatment time in stripping away a sufficient amount of the outer layer of the tooth enamel to provide the necessary tooth color modification. The applicator has two functional ends. One end has a containment pocket for holding the compound, and a second end for high pressure scouring of the tooth enamel. The compound comprises an enamel softening acid, such as hydrochloric acid, in the concentration range of between 6%-16% in combination with an abrasive particulate material. The abrasive material should have a hardness greater than 6. 0 as measured on the Mohs hardness scale for greatest effectiveness.

A mouthguard includes lateral cheek compaction domes which compressibly fill the space between the inside of the cheek and the rear teeth when worn. The domes are ellipsoid in shape and provide elasticity which allows the muscles of the cheek to comfortably grip the mouthguard. The internal aspects of the cheek compress the domes against the outer tooth and gum surfaces to hold the mouthguard in place even when the teeth are not biting on the bite plate section. This holds the mouthguard in place as the jaws move when speaking or during deep breathing.

The invention discloses a protective light shield to reduce the harmful effects of resin-curing lights used in dentistry. This is a shield made principally of a single sheet of filtering plastic, shaped in a convenient paddle configuration. The dimension of the filter-paddle is sufficient to block all direct and reflected light from the tooth of the patient that would possibly be seen by any personnel in the operatory. A portion of the paddle is provided with a magnifier which may be employed by the physician for closer inspection of the tooth being operated on. Additionally, a relatively thin intensity-filtering material is applied to the back of the light paddle so that the intensity of the filtered light is reduced for the increased comfort and protection of the physician.

An applicator system for a powered dental handpiece enables the low RPM controlled application of abrasive tooth compound. The system comprises, in combination, a speed reducer and a mandrel which includes a grooved cylindrical sleeve. The mandrel is made from substantially rigid material so that pressure may be applied to the tooth without deformation of the mandrel and, hence, increased contact surface area between the applicator sleeve and the tooth is prevented. The mandrel further includes a central containment pocket for holding and applying the tooth compound so that both inner and outer portions of the applicator sleeve are operable. A ring-shaped end portion of the applicator sleeve is effective for spot application of the compound.

A light shield for protecting dental bonding materials comprises a light filtering coverplate, a stand, and an electronic timer. This device is to be used in a dental operatory to prevent premature curing of the restorative materials after mixing as they await handling and use.
