After my older ds got his braces off, the orthodontist recommended we have his wisdom teeth removed, so we did. After my younger ds got his braces off (same orthodontist, 10 years later), the orthodontist said they no longer automatically recommend getting the wisdom teeth removed.
When I was in my 20's, I was sent for a consult to have my wisdom teeth removed because my dh was going to be stationed overseas. The dentist said he wouldn't touch my wisdom teeth because I had a nerve running right through there. However, when I was in my 40's, all of my wisdom teeth erupted (not at the same time). My dentist said that as long as I brushed them well, they could stay in my mouth, lol.
