Presently, no living bird has teeth.
The earliest remains of large flightless diving birds, Hesperornis spp., had primitive teeth. Other toothed sea birds also lived during the Cretaceous, including the flighted ichthyosaurs. Also appearing in the Early Cretaceous were the Enantiornithes, a little understood group of seemingly primitive birds. At the end of the period, the toothed birds disappeared with the dinosaurs. Since then, only toothless birds have been found in the record.
I beg to differ ... there is one bird species that is living today that has teeth
No, they are birds and birds have beaks.
Crocodiles clean their teeth by opening their mouths wide and allowing small birds called "crocodile birds" to pick food bits and debris from between their teeth. This cleaning symbiosis benefits both species as the birds get a meal and the crocodiles get their teeth cleaned.
No, penguins do not have teeth. Instead, they have spines inside their mouths and throats that help them guide food down their throat. Penguins swallow their prey whole, so teeth are not necessary for chewing.
birds dont have teeth,they have beaks. but baby birds have an "egg tooth", a tooth on the front of their beaks that helps them get out of their egg, that falls off after they hatch from the egg.
Birds of prey have talons. Lions have claws and teeth.
Birds don't have teeth.
Birds don't have teeth. the beak does that job.
Birds don't have teeth, they've got beaks instead.
No birds had true teeth, but there are some species that had serrated bills that worked as teeth.
Birds don't have teeth, but some have serrated bills.
Instead of a mouth with teeth, Triceratops had a large, bony beak similar to a birds.
No existing bird of any species has teeth. Birds have beaks.
Modern birds do not have teeth. Some prehistoric birds (family Odontornithes) had teeth, and the genes still exist for tooth buds. The problem is that the development triggers for the buds have been lost.

Many animals have absolutely no teeth at all, such as birds or anteaters. However, a sloth has four molars, but no incisors.
Toothless theropods would probably be birds. Many scientists consider birds to be theropod dinosaurs which have beaks instead of teeth.
