Tooth Extraction help? (Smoking/drinking etc)?

You need to get checked out with your regular dentist to make sure there is no infection set in,you may need antibiotics if there is. Meanwhile rinse your mouth out with salt water as this will help with healing process.I don't understand why you are still getting pain,the gums soon start to shrink which may cause only minor discomfort.I would urge you to see your dentist sooner rather than later.
