First of all, you should find out the exact cause of your problem. why did you consider bone augmentation surgery? Is it for your gum disease? or because of any tooth development defect or dental procedure defect? This cause will influence the relieving period. The pain is normal after the bone augmentation surgery. Use a cold pack or ice bag to reduce the pain and swellings and rinse with warm salt water.Are you a smoker? Smoking will adversely affect the healing period. Better you discuss your problem with your own dentist. Changing the dentist or treatment method will not be a good idea.
