Dentists often use a local anesthetic like novocaine when performing procedures such as cavity filling and tooth extraction. Most of the time, this anesthetic will not cause the patient any worrisome problems; however, as with any medication, the potential for side effects is there. Before undergoing a dental procedure, you should talk with your dentist about what to expect, especially if there are any warning signs to watch out for. That way, you'll know if you need to call your dentist or head back to the office for additional treatment. Fortunately, novocaine side effects are usually mild and not cause for alarm.
