Preventive dentistry includes instructions for proper home care, including brushing and cleaning between the teeth, use of fluoride toothpaste, dietary advice. Pit and fissure sealants, reshaping of deep grooves and special fluoride toothpastes, gels and rinses may also be part of a preventive program.

Also, athletic mouth guards to prevent sports trauma and night-guards to prevent wear and breakage of teeth from grinding of the teeth are certainly an important part of preventive care.
