A tooth that is either gummed out an angle or overlaps teeth; sometimes several teeth, giving the tooth a shark-like appearance. STS (Shark Tooth Syndrome) is usually passed through the maternal side, and is more widely pronounced with people of mixed race descent. Although it is possible to live a semi-normal life with STS, numerous drawbacks do pose obvious risks (ie; Eating, Brushing, Attracting the opposite sex). A cure has yet to be found.
