Some wisdom teeth is completely unharmful, as long as your mouth have enough space for it to grow healthy and you are sure that you can clean it properly, they make no problems.
However, if your mouth is too small, wisdoms teeth may grow in a tilted angle, this is big problem indeed. It may cause damage to other teeth since it doesn't grow upright. In addition, it may be a big problem to clean it properly so tooth decay may occur.
