Dental fluoride treatment can be administered as a finishing, through a mouthwash or dental trays. In the case of finishing, the fluoride is applied after a teeth-whitening procedure. Dental fluoride trays are held between the teeth to dispense fluoride continuously during the period they are worn.
A fluoride treatment does not take long; just a few minutes. The dentist will then instruct you not to "eat or drink within the next 30-60 minutes" so the treatment can fully absorb into your teeth.
Fluoride treatments are suitable for kids and adults alike. However, fluoride-based treatments and pastes for kids under the age of 2 should be cautiously administered. If kids swallow excess fluoride at this age range, it may lead to weaker bones, white specks on teeth, and poor homeostasis.
