Someone who is good at reading X-rays.

The existing bridge has fallen out, and each dentist has a different method, so I'm worried about what would be best. At dental clinic 1, among the three, they extract the middle tooth, perform root canal treatment on both sides, put in posts, and then redo the bridge.

Try all three root canal treatments at the dental clinic, and if they don't work, consider extracting the tooth. But if it doesn't improve, then proceed with extraction.

Is there no good way? 😢
