Dental work done

I am wondering if anyone else has had this issue

The Reserves are telling me i am class 3 dental and i need a tooth pulled. I’ve been personally putting it off because i don’t want my teeth to shift

I was told that i could get a bridge put in but the DOD takes forever to approve it

Has anyone ever had this happen before? How long does it take for the DOD to approve it? I have pretty good dental insurance but my wife doesn’t want me to pay out of pocket for something the army is taking out
