Which class of antibiotics should be avoided in children due to the risk of dental discoloration?

• A. Macrolides
• B. Aminoglycosides
• C. Tetracyclines
• D. Beta-lactams

Answer: (C)

Tetracyclines are known to cause dental discoloration in children, particularly those under the age of eight. This class of antibiotics has the unique property of binding to calcium in developing teeth, leading to yellow or gray staining. This effect is due to the incorporation of tetracycline into the tooth enamel during the period of tooth development, which can cause permanent discoloration. Because of this risk, tetracyclines are contraindicated in young children and often avoided in pregnant women as well. The age-related caution is particularly significant as it coincides with critical periods of dental formation. In contrast, other classes of antibiotics, such as macrolides, aminoglycosides, and beta-lactams, do not carry this risk of permanent staining in teeth and are generally considered safe to use in pediatric populations.
