Top definition
Noun. A tooth which grew in horizontally, as well as backwards. Essentially the tooth is pointing towards the uvula and rendered useless in functionality. Dentists find this particular type of deformity difficult to deal with as the patient must undergo intense multiphase surgery to have these corrected. The root of a naggletooth is the reason for such extensive surgery. In most cases the root will grow on the side of the jaw rather than into the regular socket. The oral surgeon must cut the root and create a new socket for the correction to take hold in the jaw.
