Wisdom removed

Yesterday, my husband went to a dentist to have wisdom tooth removed. It took him nearly 2 years to make up his mind after his dentist suggested. He said that the surgery took for a few hours when he had another wisdom tooth removed and the experience was horrible.

The extraction procedure seemed to have gone very smoothly yesterday and finished within 45 minutes. My hasband said that the anesthetic injection was a bit painful but effective. He went to bed early last night before the anesthetic wears off completely and he could eat normally this morning.

The wisdom tooth is called "Oyashirazu" in Japanese, which literally means "(the tooth that) parents don't know", because it develops after one's adolescence. I perfer the Japanese term to the English one.

Who would want his wisdom removed?
