I have and chose to have it removed, as it was the huge triple upper caranasial tooth and treating it may well not have cured the issue.
This has not affected her show career negatively (I got permission to show) as she has won several CC's since (two last year) and 1 with BOB this year.
It hasn't stopped her chewing bones etc either.
A friends bitch had one while pregnant and the vet wanted to have it out once pups were 6 weeks old as he wasn't happy to administer AB's that were strong enough to deal with it during pregnancy.
In her case it burst a few days before whelping and currently is healing, and I assume she will have it done when pups are weaned.
