A dental check up is a comprehensive assessment of the oral cavity, teeth, gums, and other related structures to check for any abnormalities, signs of disease, or decay, as well as develop an accurate diagnosis and treatment plan. During the examination, the dentist will look for any cavities, gum disease, oral cancer, misaligned teeth, bite problems, and other dental issues that may require treatment. A dental examination is an essential part of maintaining good oral health and should be done regularly, usually every six months, to prevent or treat any dental problems before they become more severe.
