Do Garter Snakes Have Teeth?

Yes, garter snakes do have teeth, and quite a lot of them. While their teeth are tiny and not designed to cause serious harm to humans, understanding garter snake dentition is interesting and useful, especially if you keep one as a pet or encounter them in the wild.

How Many Teeth Do Garter Snakes Have

Garter snakes have rows of small, recurved (backward facing) teeth on both their upper and lower jaws. They typically have between 40 and 60 teeth total, arranged in multiple rows. These teeth are designed to grip slippery prey like frogs, worms, and fish rather than to tear or chew.

The backward curve of the teeth serves an important purpose. Once a garter snake grabs its prey, those angled teeth make it nearly impossible for the prey to pull itself free. The more the prey struggles, the deeper the teeth hook in. This is a common adaptation among snakes that eat slippery, active prey.

Are Garter Snake Teeth Dangerous to Humans

Garter snake teeth are very small and not dangerous to people. If a garter snake bites you, you might feel a slight pinch and see some tiny pinprick marks, but that is about it. The bite is comparable to being scratched by a small thorn.

The biggest concern with a garter snake bite is not the bite itself but the possibility of a mild allergic reaction. Garter snakes do produce a mild venom in their Duvernoy’s gland (a gland located behind the eye), but this venom is not considered dangerous to humans. It is designed to help subdue small prey like frogs and earthworms. In rare cases, people may experience slight swelling or irritation at the bite site, but serious reactions are extremely uncommon.

Why Would a Garter Snake Bite

Garter snakes are generally docile and prefer to flee rather than bite. When they do bite, it is almost always a defensive reaction because the snake feels threatened. Common situations that might lead to a bite include picking up a wild garter snake that is not used to being handled, handling a garter snake too roughly, or accidentally startling one.

Pet garter snakes that are handled regularly from a young age rarely bite. They learn to associate their owner’s hands with safety rather than danger. If you are considering a garter snake as a pet, you can read our guide on whether garter snakes make good pets for more detailed information.

Do Garter Snakes Lose and Regrow Teeth

Like all snakes, garter snakes continuously lose and replace their teeth throughout their lives. This process is called polyphyodonty, and it means that a garter snake always has sharp, functional teeth available. If a tooth breaks off while catching prey (which happens fairly often), a replacement tooth is already growing in behind it.

This constant tooth replacement is one of the reasons snakes are such effective predators. They never have to worry about worn down or damaged teeth affecting their ability to catch and eat food.

How Garter Snakes Use Their Teeth to Eat

Garter snakes are not constrictors like boas or pythons. Instead, they rely on their teeth and mild venom to subdue prey. When a garter snake catches a worm, frog, or small fish, it uses its rows of teeth to grip the prey and then swallows it alive. The backward facing teeth prevent the prey from escaping as the snake works it down its throat.

Watching a garter snake eat can be fascinating. They use a “walking” motion with their jaws, alternating left and right sides to gradually pull the prey deeper into their mouth. The flexible ligaments connecting their jaw bones allow them to open their mouth wide enough to swallow prey larger than their head.
