as i was munching on some cookies, suddenly my mouth felt a bit weird. the first wisdom tooth of mine finally emerged with the entire of its chewing surface is exposed, and a piece of flesh became detached from the gum but still dangling on the gum. tried to pull it but it started bleeding... haiz... why must i grow wisdom tooth? will it squeeze the rest of the teeth so much the alignment became deformed? should i go see dentist?
