Dentists and consumers have long recognized the American Dental Association (ADA) Seal of Acceptance as an important symbol of a dental product's safety and effectiveness. For more than 125 years, the ADA has sought to promote the safety and effectiveness of dental products.
The first Seal of Acceptance was awarded in 1931. In 1984, President Ronald Reagan gave the Association a certificate of commendation for the outstanding self-regulatory efforts of its Seal program.
Although it is strictly voluntary, about 400 companies participate in the Seal program. Participating manufacturers commit significant resources to evaluate, test and market products in the Seal program. Some 1,300 dental products carry the Seal of Acceptance. Of these, about 45 percent are products sold to consumers, such as toothpaste, dental floss, manual and electric toothbrushes and mouthrinses. The rest are products prescribed or used by dentists, such as antibiotics or dental restorative materials.
