I don't know if he needs the tooth out--you could ask another dentist that. My daughter had laughing gas last year when she had her cavity filled. No novacaine as she hates needles. It went so much better than expected with the laughing gas. She was back in school 20 minutes after they finished. Teeth can be loose for a long time before they come out. Both my nephew and a friend's child had a problem with the tooth getting loose after a fall. The friend's child had his be loose for a year before it finally came out. My nephew's tooth still hasn't come out over a year later. My daughter's front tooth was loose for months before it finally came out. So a little loose is no guarentee that it will fall out soon.
