A dental drill is a small, handheld tool used by dentists to remove decay from teeth and prepare them for fillings. It operates using a rotating bit that can quickly and precisely cut through tooth enamel and dentin. The drill is often equipped with various attachments to perform different functions, such as polishing or shaping teeth. Dental drills are typically powered by electricity or air pressure, allowing for efficient and effective treatment. They are an essential part of modern dentistry, helping to maintain oral health and restore damaged teeth. Safety features and advancements in technology have made them quieter and less uncomfortable for patients.
