Hi!I have been feeling sick for quite some time, fatigued, lethargic, and dizzy.  I switched dentists and went to my annual check up during this evaluation the dentist recommended to have one of my amalgam fillings removed, to which I agreed.  When the dentist removed the filling, she found pieces of cotton and metal in the tooth that had been left there, decomposing for more than ten years.  The dentist prescribed antibiotics for a possible infection.  I wonder if my body has been fighting a tooth infection for some time and how that has affected my health.  Also, I would like to know how to boost my immune system.

Hi. Welcome to Chat Doctor. As per your complaint in case if you have a deep decay in tooth that has become chronic due to not treating it, it can cause septicemia and bacteremia that is due to advancement of bacteria from the site of tooth infection to the body via blood and can cause infection with symptoms like fever, lethargy etc. But in your case it does not seem to be the cause and the problem of fatigue, dizziness and lethargy does not seem to be due to tooth infection caused by cotton placed in the tooth as you did not have pain in tooth that means the infection did not progress deeply. So my suggestion is to consult a General Physician and get evaluated and a thorough clinical evaluation and investigations like complete blood picture and also checking up your ear and MRI scan can help in diagnosis and treatment can be done as per cause. As far as tooth is concerned, it does not seem causing these symptoms, however you should get a proper tooth colored filling done for saving the tooth. Hope this helps. Regards.
