Cách sử dụng
A cavity is a hole or opening in a tooth. It is caused by tooth decay, which happens when acid breaks down the tooth's outer layer called enamel. Cavity is a commonly used word when talking about dental health and hygiene. Dentists will often ask if you have any cavities during a check-up and may recommend getting a filling to fix any cavities that they find. It is important to brush your teeth twice a day and floss regularly to prevent cavities.
