He will be just fine. Many have overbites or underbites. It doesn't affect their health unless they have other dental or mouth problems as the incisors aren't really used a whole lot, they are the first teeth you see go when they get old.
My Lillie has a severe underbite. It looks like she is smiling all the time. It doesn't cause her any problems though.
Unless you got them under a show contract, underbites and overbites are not covered in health guarantees as bites go bad all the time and they don't pose any health problems. |
