foul mouth odour can be due to a variety of problems. Most commonly, it indicates bacterial deposits on your teeth (plaque and calculus
), which can be easily eliminated with a professional cleaning by your dentist
. Occasionally it might arise from food debris accumulation within tooth cavities
that may need to be filled, or in spaces between teeth which may require more frequent professional attention and regular, thorough interdental cleaning. Occasionally, foul mouth odour might also arise on a background of certain systemic diseases, and would improve as those diseases are controlled.
See your dentist and discuss the problem with them, so the appropriate solution can be identified based upon an accurate diagnosis.
Hope this helps.
