Customer Question

I am experiencing a sour, bitter taste in my mouth. After flossing and brushing, it is no longer there, but returns, sooner via post-nasal drip (the drip is really sour - not normal).

Thanks for coming.

I am a double board certified US doctor and will help you with this.

It is not necessarily normal.

It can be from gum disease.

It can be from sinus infection.

It can be from acid reflux [this is a common cause and often not diagnosed.]

It can be from a problem with smell as well, but this would not really respond the way you are describing.

I suggest you go over this list with your doctor ASAP.

Not an emergency, but might need treatment.
