For being wise, they are completely useless. I had alot of mouth pain over the last few days so I ended up going to the dentist just to have it checked out, just to be safe and plus it been quite awhile since I have had my teeth cleaned. The dentist took one look at my mouth and sent me to get a new x-ray. He came back in and first thing he asked was “They need to go” Just what I wanted to hear. Anyway, as much as I was trying to avoid getting them pulled, it seems like I have no choice for this.
