Periodontics/Bitter taste in mouth


Hi, a few days ago I woke up with a bitter taste in my mouth.  It varies in intensity. I do not take any medications and I am healthy.  I went to my general dentist in July and had my teeth cleaned and xrayed and was told everything was fine. In the past year I have had 2 osseous surgeries and one of them  had regeneration.  This is the fifth day that I have had this and eating seems to make it worse. Should I see my family physician, my general dentist or my periodontosist?  I have my teeth cleaned 4 times a year. Thank you!

It is very difficult for me to guess what is causing the bitter taste. I do not have any information regarding the health and condition of your teeth and gums. For instance, why did you have the surgeries if everything was fine?

However, if your teeth and gums really are in good condition, then the reason might be in your nose or throat. Or in what you have been eating or drinking lately. Or maybe you have some new infection, caused by bacteria, fungi or viruses.

Try cleaning your teeth extremely carefully and flossing in the evening so that the floss reaches under the gum line. You could also try cleaning the surface of your tongue.

If your problem persists, see first your periodontist. If nothing is wrong in the mouth, you could make an appointment with an otolaryngologist who examines your nose, throat and ears.
