Tooth decay, also known as dental caries, is a process where bacteria in the mouth produce acids that gradually dissolve the enamel, the hard outer layer of the tooth. This occurs due to the interaction between bacteria, sugars from food, and the tooth’s enamel.

Cavities and dental decay can produce a foul odour, especially when left untreated.

Flossing can help remove plaque and bacteria from areas that may be difficult to reach with a toothbrush alone, preventing the progression of dental decay and minimizing associated odours.

By flossing regularly, you can help prevent the build up of plaque, reducing the risk of cavities and gum disease. Flossing complements brushing by reaching areas that a toothbrush may not effectively clean, contributing to overall oral health and preventing tooth decay.

5. Infrequent Flossing:

7. Medical Conditions:

Sometimes, bad-smelling floss may be linked to underlying medical conditions such as dry mouth or sinus issues.
