Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Well, I have hardly seen anyone having acid reflux due to
tooth infection or any other dental procedure and it can be either due to
hyperacidity caused by antibiotics and painkillers that are given post treatment.
There can be many other causes of acid reflux like intolerance to certain foods or medicines etcetera.
As soon as you switch over to clean eating then there is a possibility that you don't eat certain foods that is causing acid reflux.
So, my suggestion is to consult a General Physician and get evaluated so that it can be ruled out that what is the cause for acid reflux and appropriate treatment can be advised.
I do not think it is due to tooth infection or
root canal treatment. So, you can be advised antacids like
Milk of Magnesia half an hour before meals and
proton pump inhibitors like Omeprazole.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
