Will a damaged tooth eventually have to be pulled?!

Lets see, when I was in grade five I chipped my front teeth on the monkey bars and a new end was bonded on!. The doc said we would have to wait to see if the tooth would heal!. Well, Im now a junior in college, bonding still good, but both my front teeth have had a fracture(internal crack) that runs down the length of them that is apparent (i dont if its apparent to everyone or just me)!. These "internal cracks" have been there since fifth grade as well!. I go for regular dental checkups, everythings seems okay, teeth sensitive to extreme hot or cold but i knew that would happen since the accident!. I just got my braces off, and after having hidden the fractures and bonding for three years, no brackets has sent me spinning!. All i can notice is the break, not the straight teeth!. Will these teeth last if I keep taking care of them, or will they eventually have to be pulled!?!?!?!? I think my teeth are so ugly!. Straight but unhealthy!. Maybe im over-reacting!. I just think its unfortunate!.Www@Answer-Health@Com
