Tooth pain has many reasons. Firstly we need to know where exactly the pain is. It would be easy to diagnose if you could upload a picture of the left side tooth's.
If it is due to the very last teeth - your more likely advised to get it extracted
If the bleeding is due to periodontal ( gum) problems- scaling will help.
If it is due to decay in any tooth - might go for a RCT
Next Steps
see a dentist immediately.
