吃飯弄崩牙

到牙醫處，他會幫你做一個牙套，套在原本的牙上。不過都要好幾千元。

i havent seen tooth fracture extension so i cant tell u the exact answer.

But according to ur description, i think the fracture only involve enamel or at most involve enamel and dentine.

So there are 2 solutions:

1) do the tooth colored material filling to replace the tooth substance lost
2) make a crown which is like a cap in tooth color covering ur tooth
3) do some polishing and leave it

advantage and disadvantage:

1) do the filling is cheaper and the process is simple but the fiiling has a chance to dislodge oneday depending on size of filling and the eating habits

2) make a crown is long lasting but is more expensive and need to trim the tooth into a small one in the process

3) leave it is cheapest way but the tooth is not looking good and may lead to sensitivity
