Which statement about Teeth discoloration is correct?

• A. All tetracyclines cause teeth discoloration
• B. Doxycycline causes more discoloration than other tetracyclines
• C. Most tetracyclines cause teeth discoloration, with doxycycline as an exception
• D. Teeth discoloration is not a concern with tetracyclines

Answer: (C)

Teeth discoloration from tetracyclines happens when the drug chelates calcium and becomes incorporated into developing teeth and enamel during fetal development or early childhood. This causes intrinsic staining that can be permanent, often varying from yellow to brownish-gray, and the risk increases with longer exposure during tooth formation. Most tetracyclines have this staining risk, but doxycycline shows much less tendency to cause discoloration because of its chemical properties and how it distributes in developing teeth. Because of this, doxycycline is often considered an exception to the general staining risk associated with tetracyclines.
