Get the root canal. there not as bad as people make them out to be.
(Registered dental assistant)

My son knocked his tooth out, had it reinserted, bonded, and had a root canal when he was 3. He had the same tooth pulled because of infection when he was 4. And all this on a BABY TOOTH!
It cost a lot for these procedures and when I look back on it they were worthless considering the baby tooth would have fell out anyway.
I would miss the tooth, but why have the chance of it needing more work later?
