(HealthDay News) -- Cavities are permanently damaged areas of your teeth. They have a range of causes, from bacteria to sugary drinks and poor dental care.
Symptoms of cavities also vary. Initially, people with a cavity may have no symptoms. But as the cavity gets larger, warning signs such as pain and tooth sensitivity may emerge.
If cavities aren't treated, they can grow and affect deeper layers of your teeth, according to the Mayo Clinic. This can cause severe pain, infection and tooth loss.
Both regular dental visits and good brushing and flossing habits are the best ways to help prevent cavities.
