This is quite difficult for you Emily! Hopefully you'll have that whole jaw area and teeth looked after for normality, without huge costs beyond what you predict.
Were you conscious when the impact occurred? I am wondering if you had a small concussion also. The impact seems enough. What did the neurological assessments provide for you by doctor?
Keep us posted!

(When another adult cyclist crashed into me on a bike path, I was actually unconscious for several hrs....even though my eyes were wide open, I walked abit and was talking/repeating myself. My partner didn't realize I was "unconscious" until I was transported by ambulance to hospital. So I temporarily lost my short-term memory for a few hrs.. I have no memory of the actual collision, ambulance transport, CT body scan.... In a way, I'm glad I have no traumatic injury flashbacks..)
