Peacocks do not have teeth, no. Birds, in general, do not have teeth so this is nothing unusual.
The reason why birds do not have teeth is that it would make it more difficult for them to fly.
Teeth are heavy, birds need aerodynamic beaks and a lightweight structure to air their flight. This doesn’t mean they can’t break up and digest hard foods though, as I’ll explain.

What Type of Teeth Does a Peacock Have?
Peacocks do not have any type or form of teeth. There is some scientific evidence that birds may have had teeth at one point, but they evolved without teeth as it allows them to fly better.
Peacocks are not able to fly as well as other birds, but they still have all of the same 'design features' as birds that do fly.
This is the same as chickens. Chickens have become pretty much flightless birds, but they have wings, hollow bones, and no teeth.
This doesn't mean that peacocks cannot break up and digest tough foods though.
Their beaks are very tough and sharp, and like other birds, peacocks have a clever digestive system that 'chews' up the food for them.
Do Peacocks Have Gizzards?
The reason why peacocks are still able to eat a wide range of foods without having teeth to chew is that they have an organ called a gizzard.
A gizzard is essentially like a second stomach compartment and is a strong muscle. When food enters the gizzard it contracts and basically 'chews' or breaks up food.
It does this with the help of some coarse materials, which is why peacocks eat bits of grit when they're foraging.
After the gizzard has done its job, food then moves into the small intestines where the nutrients are absorbed.
Leftover bits of food or the parts that do not provide the right nutrients then exit the peacock in the form of waste matter.
Do Peacocks Bite?
Peacocks do not bite, no. They can't really as they don't have teeth.
They will peck at things - and this includes us - if they feel threatened, and that's almost as bad as being bitten.
A peacock's beak is incredibly tough, and it's fairly sharp, too. You'll know it if your fingers get a little too close!
They don't bite things to break them up or chew them though. Peacocks peck at foods to break them up using the tip of their beaks, then they swallow bits of food whole without chewing them.
So, instead of saying they bite, I’d say peacocks peck or nip at things. But whatever you want to call it, it hurts if a peacock has a nip!
Has a Peacock Ever Killed Anyone?
This is an interesting question that someone asked me recently - has a peacock ever killed anyone?
I did a lot of research, and thankfully I've not been able to find any evidence that a peacock has ever killed anyone.
There have been some incidents where a peacock has attacked someone, often a small child, and there's some pretty serious harm though.
It's a reminder that although peacocks are magnificent and beautiful-looking birds, they are wild animals and are equipped with some defensive weapons.
Peacocks have hard beaks, sharp claws, and spurs. Three things that they can use to cause harm to other animals and humans if they feel threatened.
They're not known for being aggressive, but during mating season, in particular, they will charge at and fight other peacocks to win the affections of a mate.
They'll also defend themselves and their ostentation or muster of flock mates if needed.

Do Any Birds Have Teeth?
I was not able to find any species of bird that has teeth. According to BirdSpot, birds evolved from reptiles that did have teeth called Archosaurs.
The gene that is responsible for producing teeth ‘switched off’ around 100 million years ago - so just a few years!
There have been mutant strains of the gene reappearing and some rare cases of birds growing teeth, but that’s a pure mutation.
There are some birds with tiny ridges lining their beaks that almost have a teeth-like feel. This is an interesting little insight into what may have once been, but it’s not teeth.
On a side note, this is why the phrase, “As rare as hens' teeth” is used to describe something that is very unlikely to happen.
To further complicate the matter, this is not to be confused with an egg tooth. Most birds are born with something called an ‘egg tooth’.
An egg tooth is a hard white protuberance that they have on their beaks that they use to break out of their shells.
This drops off in the coming days and is not related in any way to an actual tooth.
In Summary
Now you know, peacocks do not have teeth and I’ve also explained why they do not have teeth and do not need them.
The anatomy of birds, and peacocks, in particular, is fascinating. They’ve evolved in a way where they not only do not need teeth, but they’re better off without them!
However, keep in mind that this doesn’t mean you’re safe from being pecked at!
