Do parrots have teeth? No. They don’t use their teeth to crush their food into smaller pieces. So what do they use to break down their food? What do they have instead of teeth?
One might think that all birds have teeth, but this statement is wrong. Although it’s true that some birds have teeth, parrots are not one of them. After all, they don’t really need teeth—their strong beaks are enough to crush grains and seeds. In addition, they have stones and acid in their stomach to further aid in food digestion.

Why Parrots Don’t Have Teeth?
There are two theories to explain why birds don’t have teeth: to optimize their center of gravity and increase their survival rate.
The weight of a bird can affect how well it can fly. Their center of gravity is the area where the wings and body meet. Teeth weigh a lot, and so do the jaw muscles needed to make them functional.
Let’s imagine parakeets have teeth; the added weight will shift their center of gravity. As a result, they will have trouble lifting their bodies off the ground. In other words, ditching teeth improves the ability to fly in birds, including parrots.
Another possible reason for forgoing the teeth is for survival. It takes time for teeth to form, which extends an egg’s growth timeline. This means the parents will need to guard and care for the eggs longer than usual, which exposes them both to more dangers.
How Do Parrots Eat Without Teeth?
Even without teeth, parrots can still break their food into manageable sizes before swallowing them. So how does their digestive process go?
After picking seeds and grains, parrots use their beaks to tear them into smaller pieces that are easy to swallow. They will then move the food around their mouth on their tongue before pushing it down on their throat. The food will arrive at the crop where it is stored.
Parrot’s Digestive System
Birds have two stomachs. The first one is the proventriculus, where the food is softened with acid. After that, the food is sent down to the second stomach, called the gizzard. This is where the hard muscles and gastroliths further grind the food into smaller pieces.
In addition, parrots may swallow tiny gravels that act as “teeth” to aid the digestive process in the gizzard. These stones are especially helpful if the birds’ diet mainly consists of hard-shelled grains.
The digestive process will end in the intestine, where the nutrients from the food are absorbed. Then, you can expect to clean up some parrot poop after a few hours.
What Do Birds Have Instead of Teeth?
Instead of parrot teeth, these birds have beaks. These two plates or mandibles are made of hard material capable of tearing and splitting seeds, grains, fruits, and other foods in their diet.
In addition, parrot beaks have hooks that not only help them break down their food but also pick up almost anything. Different parrot species might have different colored or shaped beaks, but they function just the same with impressive dexterity.
And as pointed out, the stones that parrots swallow are their substitutes for teeth when they need to digest particularly hard food.
Frequently Asked Questions
Are there any bird with teeth?
There are no modern birds with teeth. Several bird species look like they have sharp teeth. While the appearance is convincing, these are not natural teeth and are not functioning as one.
How did parrots lose their teeth?
Birds lost their teeth through evolution over a million centuries ago. Theropod dinosaurs, which are avian’s common ancestors, exchanged their teeth for beaks to increase their chances of survival.
How? There is a gene present in all birds that can disable the formation of teeth. It is still a mystery how it exactly happened, but one thing is sure: the disappearance of the teeth and the development of the beak took place simultaneously.
Do birds have teeth in their beaks?
Again, there are no birds that have teeth. Some might confuse the marks on an avian beak as teeth since the appearance looks like it. However, these ridges are only indentations called tomia. And although tomia might make food more manageable in some birds, such as geese, they don’t have the same tissue structures as teeth.
In addition, birds’ beaks are made of keratin, which is not suitable for eating and cannot grind food particles as effectively as teeth.
Do birds have tongues?
Yes. The tongue of a parrot is the reason it can mimic sounds and speak like humans. But it is not just that.
Parrots’ muscular tongue supports the movement function of the beak. It also allows the birds to grip and control food and objects. This means the tongue, together with the beak, plays a significant role in the handling of food from the mouth to the throat.
Do parrots have teeth? No, they don’t. Parrots are toothless because their common ancestor swapped their teeth for beaks for survival. Having no teeth is not a disadvantage for them but a strength.
