What Causes Sewage Taste In Mouth And Suggest Treatment?

Hello, The condition of your mouth including tongue, teeth and gums can be a factor. Have you had a recent dental exam and cleaning? Be sure to practice good oral hygiene including brushing your tongue. Infected tissues can change your taste. Infections under the gums can drain and these can give you a bad taste. Drainage fom the sinus to the back of the throat such as a post nasal drip can affect your taste. A dry mouth, again, affects taste. Other habits such as smoking or recently stopping a habit such as smoking affects taste. Medications? Any recent antibiotic treatment can affect the balance of your oral bacteria. The back of your throat may collect debris prone to attack by bacteria. Tonsils have crater like areas for debris to get caught. Tonsil stones or tonsilloliths are unpleasant. They can be foul smelling and require removal. Have a doctor check this area. You may be able to see some debris yourself and can try vigorous rinsing. A foaming, peroxide rinse may offer some assistance. Professional treatment may include removal, antibiotic treatment and removal or reshaping of the tonsils. I hope you are able to remedy this situation soon. Additional questions are welcome.
