Tooth decay is driven by harmful bacteria living in your mouth

Your mouth is filled with bacteria, fungi, and viruses - collectively called the oral microbiome! Some of these microbes are beneficial and can contribute to good oral health. Others are pathogenic and cause damage, leading to painful & visible symptoms of disease.

Cavities (caries) are driven by specific types of bacteria that live in your mouth. These bacteria feed on food particles and release acids that erode your enamel.
