Points to note when using fluoride-containing products
Generally, a young child should use a pea-sized blob of children toothpaste which contains a lower concentration of fluoride. Ingestion of excessive amount of fluoride will lead to dental fluorosis with white patches found on the newly erupted permanent teeth.
Topical fluoride used by professionals
These topical fluoride agents are in very high concentration. The application of topical fluoride on the tooth surfaces can prevent tooth decay or reduce tooth sensitivity. The dental care personnel usually choose a type of topical fluoride which is appropriate for the patient's oral health condition.
