Regular dental check-ups are essential for maintaining oral health. During these exams, dentists assess the condition of the teeth, gums, and surrounding oral structures, and may perform diagnostic tests such as X-rays to detect any issues early. Professional dental cleanings, also known as prophylaxis, involve the removal of plaque, tartar (hardened plaque), and stains from the teeth. This helps prevent tooth decay, gum disease, and other oral health problems.
