What is the narrow band of a tooth that is surrounded by the gums called?

The term for the narrow band of a tooth that is surrounded by the gums is known as the neck. This part of the tooth is particularly important as it connects the crown, which is the visible portion above the gum line, to the root, which is embedded within the jawbone. The neck is situated at the gum line, and it's where the transition occurs between the regions of the tooth that are above and below the gums. This area is also significant because it can be susceptible to periodontal disease if plaque and tartar build up, leading to gum recession and other dental issues. Understanding the anatomy of the tooth, including the neck, is essential for maintaining oral health and recognizing any potential problems that may arise.
