Replying to New tooth crown!!

i busted my molar in half at lax pratice and my nerve is exposed it kills!!!!, but tommrow i go to the dentist to get it fixed and my mom said they may give me a root canall and put a crown on it and if they do can get a gold one, silver one, or a porcelin (white like glass) one. I am thinking if i had to i would go silver and then when i am like 30 and dont like it be like "it FELL off" or just go white and have it look normal, it may only be the half of the tooth so procelin would win, but it its a cap i think silver and crown i think silver OR porclien.

and no i am not really thinking gold at all thats just gay and it would be too noticable if i didnt want it to be seen.
