Actually, buck teeth are teeth that are usually at the front and are crowded together. Fangs are long, pointed teeth that are usually farther apart, and are often at the canine tooth position.

Regardless, this may be a case of is it necessary to assign these kinds of categories to characters? Is it important to know what kinds of teeth each character has?

If you're adding a category just to add a category, and it's not really significant to the plot, then it probably doesn't need that category.
