Tartar control toothpastes contain sodium pyrophosphate. This substance hangs onto the interior of the tooth to prevent tartar formation. These toothpastes do not remove existing tartar, but can prevent it from further development. It is best to start using a tartar control product right after a dental cleaning. Other special products are designed for people who need desensitizing toothpaste or antimicrobial toothpaste.
All toothpaste is more effective right after a dentist's regular cleaning.
A visit to the dentist every six months or as often as a personal dentist recommends is the general rule.
