bruised tooth

[sk8rs_s0uL]

got into a bike accident where my tooth was damaged and broke but i got an x-ray and my dentist said everything is still lodged in and looks okay...6 months later i notice some discoloration especially after i got my teeth whitened and so i got another x-ray and my dentist saids it still looks okay no need for a root canal but what about the discoloration...i just wanted to get some different opinions and insight on what it may be and what i can do...thanks

yes sounds like your nerve is slowly dying.... when it turns light grey color then its signs of the tooth dying...

Trauma to a tooth can cause it to die, and discoloration is a sign of this.
