Patient: I had a toothache once in 2004 and then went to your hospital for treatment of pericoronitis in April of this year. The day before yesterday, I went to the surgery and had dental x-rays taken, but the doctor told me to have 4 wisdom teeth extracted without looking at the films. I would like to ask if I need to pull out all the wisdom teeth on the left side of my jaw that have been inflamed? Why did the doctor say that 4 teeth should be extracted without looking at the dental film? Department of Restorative Dentistry, Dental Hospital: The indications for wisdom tooth extraction include: frequent inflammation, pain, or absence of opposing teeth, or severe decay, or joint disease. If the wisdom tooth erupts in a normal position and does not have any of the above conditions, it does not need to be extracted. From your case, one wisdom tooth often causes pericoronitis and should be extracted. The other 3 wisdom teeth should be diagnosed only after examination.
