I have a decaying tooth, My internal medicine doctor put me on Amoxicillin 500 mg 3 times a day until I see my dentist tomorrow, but I have been told, that they cannot give me a shot until the swelling has gone down, it has been 3 days and on the inside below the bad tooth it has not any smaller. My doctor gave me 10 days of amoxicillin, so how can my dentist treat me since the swelling has not gone down, I am a diabetic and my blood pressure is a little high. I am on Medicaid, so it does not cover any dental, that's how my teeth got this way. what will the dentist do about the swelling inside on my gum, which is below the bad tooth?
