Ever wondered how dentists fix cavities? The cavity method is a fascinating process that helps keep our teeth healthy and strong. Cavities, also known as tooth decay, are caused by bacteria that produce acid, which eats away at the tooth's enamel. When a cavity forms, dentists use a specific method to clean out the decay and fill the hole to prevent further damage. This process involves several steps, including numbing the area, drilling out the decayed part, and filling the cavity with a special material. Understanding these steps can help you appreciate the importance of dental care and why regular check-ups are essential. Let's dive into 38 interesting facts about the cavity method that will make you a dental expert in no time!
