A persistent unpleasant taste in the mouth can indicate inflammation in the gums or jawbone. This is common with periodontitis or a periodontal abscess. The unpleasant taste is caused by pus or bacterial products being released. Bad breath often goes with it. If you notice this, it is important to make an appointment with your dentist or dental hygienist straight away. The clinician checks whether there are deep periodontal pockets or other sources of inflammation. Treatment may consist of cleaning, rinsing or opening an abscess. It is important not to wait, because the infection can spread. Good oral hygiene and regular cleaning prevent these complaints. After treatment, the taste usually disappears quickly.
