Dentists will recommend removal if their growth might do damage to the surrounding areas. However, wisdom teeth are not something to worry about as a patient. If you have regular dental visits, your dentist can advise you if they need to be removed. The procedure is fairly minor with patients receiving anesthesia to minimize any pain.
After removal, you can apply ice to the outside of your mouth for 20 minutes at a time if you experience any swelling. Doing this for a couple days after the procedure will also help with any discomfort. Talk to your dentist using taking over-the-counter pain relievers as needed. Take comfort in knowing the procedure is common and recovery is swift.
