Tylenol is a brand name for acetaminophen, a common over-the-counter pain reliever and fever reducer. It is often used to relieve minor aches and pains, such as headaches, backaches, and toothaches. Acetaminophen is also used to reduce fever.
It is generally considered safe to take Tylenol before going to the dentist. In fact, some dentists may even recommend taking Tylenol before a dental procedure to help reduce pain and discomfort. However, it is important to follow the directions on the Tylenol package and to not exceed the recommended dosage. Taking too much Tylenol can lead to serious side effects, including liver damage.
