hi, im 31 now. When i was abt 15 yrs old, my tooth cracked and ignored it thinking it does effect anything. However it starts to decay and hurts so bad that i plead the dentist to pluck it out immediately. And it leaves a hole(missing tooth) until now. I have noticed the hole became smaller now. And i also realised my face shape, lips and smile changed (apart from getting old). I want to know does it change anything? And also what can i do to have a gorgeous smile again?
