Foul taste in mouth - help?

See a dentist: Brush, floss, and use a listerine-type mouthwash. If the taste/odor doesn't go away, see your doctor to rule out a throat infection, then see a dentist to evaluate for a tooth abscess.

Oral hygiene: The most likely cause is poor oral hygiene. Start brushing, flossing, using a tongue scraper and rinsing with listerine or crest prohealth on a routine basis after meals. There are many other possible causes such as an infection and gum disease, just to mention a few. Therefore you should see a dentist for a complete and thorough evaluation. There are also less likely medical implications.
