Dental disease refers to a range of conditions that affect the teeth and gums, leading to pain, infection, and other health issues. Common types include tooth decay, which occurs when bacteria produce acids that erode tooth enamel, and gum disease, characterized by inflammation and infection of the tissues surrounding the teeth. Preventing dental disease involves maintaining good oral hygiene, such as regular brushing and flossing, along with routine visits to the dentist. Early detection and treatment are crucial to avoid complications, including tooth loss and systemic health problems linked to poor dental health.
