I asked 2 dentists if I should get braces or not. But 1 dentist said I should get one and the other said it's not really necessary. My lower jaw has an arch that is "V" shaped or form which is suppose to be an "U" What do you think I should do? Should I get braces or not? What could possible happen if I don't? Will my chin grow pointier if I don't get braces or not? Can it affect the growth of my jaw and appearance?
