Dental visits

I am curious whether any other hiprunners get different advice about taking antibiotics before every dental visit? My Dr. says I need to do this for life for every visit (cleanings, fillings, etc.). Last week I had a cleaning and the prescription I got was 4 tablets of amoxicillan (2000mg) which I had to take all at once an hour before the appointment. The dentist says I am low risk because I keep up with my dental care and don’t have any apparent issues. I do need one small filling and have to go back in a couple more weeks to get it filled – meaning another 2000mg of amoxicillan. I emailed my Dr. to see if there was any new guidance and to let him know my dentist thought I was low risk. He said the same thing – I have to do this for every visit for life. This is driving me crazy! It’s so bad for the digestive system. It’s hard enough to keep the good “bugs” healthy without killing them off periodically. Is anyone not taking the antibiotics or getting different advice?
