I myself had the one molar surgically removed.
I remember the day it cracked due to cavaty. I was dissapointed with myself because I always brushed my teeth but turns out I missed that spot all the time. While my mother was not dissapointed in me given she taught me the importance of oral hygene I felt I let her down a bit.
Good news however that molar was a long overdue babytooth so even removed I got a bit of a back up poking through the stump.
I also have a bit of a snaggletooth premolar which is like my personal anime fang. The babytooth behind it is a little loose and will probably come out sooner or later.
The only dental problem I usually have is tartar build up behind the lower incisors but I don't mind the dentist chisling it out for me every time I get a check up.
