What is the normal range of gingival depth in a healthy mouth?

• A. 1-2 mm
• B. 0-3 mm
• C. 2-3 mm
• D. 0-5 mm

Answer: (B)

The normal range of gingival depth in a healthy mouth is considered to be between 0 to 3 mm. This range indicates that the sulcus, or the space between the gum and tooth, is shallow and healthy, without signs of periodontal disease. A depth of 0-3 mm is a standard measurement used in dental assessments, where depths greater than 3 mm typically suggest periodontal issues, such as inflammation or disease.

A depth at or within this range suggests adequate attachment of the gingival tissue to the tooth without the presence of pocketing, which is crucial for maintaining oral health. Monitoring gingival depth is essential for identifying early signs of gum disease, making it a vital part of regular dental examinations.
