Permanent teeth are the second set of teeth that humans develop, typically starting to emerge around age six. These teeth replace the primary teeth, also known as baby teeth, and are meant to last a lifetime. There are 32 permanent teeth in total, including incisors, canines, premolars, and molars. Unlike primary teeth, which fall out as a child grows, permanent teeth are designed to endure the wear and tear of daily use. Proper dental care, including regular brushing and visits to the dentist, is essential to maintain the health and longevity of these teeth.
