A Crown vs. Root Canal - Deep Filling

WARNING gross picture. It’s the last tooth on the upper right.

I’d like to know my options regarding a deep filling that is now giving me sensitivity when swishing with cold water. It was filled a month ago. I’ve had no problem drinking any liquids as long as I don’t intentionally swish it to the other side. If I do swish it accidentally, the pain only lasts a few seconds and subsides. I have started a sensitivity toothpaste in hopes it helps a little.

The tooth has a pretty deep filling and I’m certain he’s going to push for a root canal. I hate the thought of taking a very much alive tooth and killing it without an infection present.

Would asking to try a temporary crown be unreasonable? And if it works, ask for a permanent one? My friend was in the same boat and a crown seems to be working for her. I know every situation is different, though.

I’m not as scared about the procedure as much I am about killing my tooth. I read that a root canal is basically mummifying the tooth.

I know a picture can’t tell anyone much but I’m most interested if a crown would be an unrealistic option at this stage?

Can't tell anything from that photo sorry.
If the tooth is sensitive to the cold and the pain doesn't linger, then the nerve is still healthy and a root canal wouldn't be the most optimal treatment.
A crown might help or might make it worse, it's impossible to tell you without examining you.
