Hello, according to your description, your condition may be gum inflammation after dental plastic surgery, which is due to inaccurate porcelain teeth, poor sealing of porcelain crown edge, or direct compression of crown edge to cause gum inflammation and easy bleeding. This kind of porcelain tooth belongs to bad repair, so it is recommended to go to a regular hospital to find a professional doctor for examination and symptomatic treatment. I hope the above is helpful to you and I wish you a speedy recovery.
