Llamas, originally from the Andes mountains but now increasingly common pets and livestock in other parts of the world, are herbivores. That means their teeth are specially adapted for eating plants.
Understanding llama teeth is critical for keeping these animals happy and healthy. This article will explore the structure and function of llama dentition, including the different types of teeth they have, their dental formula, and what those so-called “fighting teeth” are all about.
Llama Dentition: An Overview
Llamas are herbivores, so their teeth are designed for grazing and grinding plant matter, such as grasses and other vegetation.
Llamas are pseudo-ruminants, which means that they have a three-chambered stomach. They also regurgitate food for further chewing, which helps them break down tough plant fibers.
An adult llama generally has 30 to 32 permanent teeth, although this number can vary slightly from llama to llama.
Llamas are diphyodonts, meaning that they have two sets of teeth over their lifetime: baby teeth, also known as deciduous teeth, and permanent teeth.
Types of llama teeth and their functions
Llamas have a unique dental arrangement that allows them to graze efficiently on tough vegetation.
Incisors and the dental pad
Llamas only have incisors on their lower jaw. These incisors work against a hard, bony dental pad on the upper jaw. This arrangement allows them to grab and tear off mouthfuls of grasses and other vegetation.
The incisor formula for llamas is 1/3, meaning they have one incisor on each side of the upper jaw (none really, since it’s a dental pad) and three incisors on each side of the lower jaw.
Premolars and molars
Located further back in the mouth, the premolars and molars grind plant material into smaller pieces for digestion. The premolar formula is 1-2/1-2, and the molar formula is 3/3. These teeth are essential for breaking down tough plant fibers during chewing.
Canines
Llamas do have canine teeth. They’re more prominent and functional in males, where they’re sometimes referred to as “fighting teeth.”
Fighting teeth: purpose and management
Male llamas develop prominent “fighting teeth,” which are modified canines and incisors that they use to battle each other. These teeth erupt when a male llama is around two or three years old.
Females may have these teeth as well, although they’re often smaller or not fully developed. In female llamas, fighting teeth tend to show up later, around the time they turn four or five.
To prevent injuries to other males in a herd, vets often recommend removing fighting teeth from male llamas. That’s especially the case in herds where males compete for dominance.
It’s also important to regularly trim llama teeth, especially the front incisors, to prevent dental problems.
Dental formulae and eruption timelines

Dental formulae explained
The deciduous dental formula, or the formula for baby teeth, is 1 1 2 (3) 3 / 1 1 (2) 3 = 9/11. These numbers represent the number of incisors, canines, premolars, and molars on just one side of the upper and lower jaw.
The permanent dental formula, or the formula for adult teeth, is 1 1 1 (2) 3 3 / 1 1 (2) 3 = 14/16.
Eruption timelines
Incisors erupt between 2 and 4 years of age, and canines erupt between 2 and 3 1/2 years of age. Premolars typically erupt between 3 1/2 and 5 years of age, and molars erupt anytime between 6 months and 4 years of age.
These timelines can help you monitor the dental development of your llama.
In Closing
Knowing about llama teeth is key to helping these animals thrive. Understanding their unique dental structure, including those sometimes troublesome fighting teeth, is crucial for good llama management.
Routine dental care, including trimming teeth as needed and removing fighting teeth when appropriate, is important to a llama’s quality of life.
By learning more about llama teeth, owners and veterinarians can team up to give llamas the best possible dental care.
