Do birds have teeth?

• A. Birds have teeth
• B. Birds do not have teeth
• C. Birds have enamel-coated teeth
• D. Birds molt teeth

Answer: (B)

Modern birds do not have teeth. Their mouths are instead equipped with a beak made from bone covered by a keratinized sheath called the rhamphotheca, which forms the functional edge for grabbing, tearing, and handling food. Teeth require enamel and dental tissue that birds don’t develop, so there’s no tooth eruption or replacement in living species. This design helps keep the head lightweight for flight, while digestion is supported by the gizzard, which grinds up food with the help of ingested grit. It’s worth noting that some ancient birds and their dinosaur relatives did have true teeth, but in today’s birds, teeth are absent.
