Teeth should be air-dried before a fluoride varnish is applied.

True
False

Explanation

Answer: B - It is not true that teeth should be air-dried before a fluoride varnish is applied.
Fluoride varnish will adhere to teeth which are not completely dried. Excess saliva may be suctioned or wiped away with gauze, which is ideal for patients with dentinal hypersensitivity for whom air drying would be rather painful.
