Homonym: Cavity (Hollow)
A cavity is a small hole that forms in a tooth when bacteria break down sugars and produce acid. This acid can eat away at the hard outer layer of the tooth, called enamel, leading to decay. If not treated, cavities can cause pain and may require a visit to the dentist for fillings or other treatments.
To prevent cavities, it's important to practice good oral hygiene. This includes brushing your teeth at least twice a day with toothpaste that contains fluoride, flossing daily, and visiting the dentist regularly for check-ups. Eating a balanced diet and limiting sugary snacks can also help keep your teeth healthy.
