When you look in the mirror and examine your smile, you might wonder about the different types of teeth you have and what makes each one special. One term that often causes confusion is “eye teeth.” So, which are eye teeth exactly, and how can you identify them in your own mouth? This comprehensive guide will help you understand everything about these fascinating teeth and why they’re so important.
Identifying Your Eye Teeth
Which are eye teeth in your dental lineup? Eye teeth are your canine teeth, also called cuspids. They’re the sharp, pointy teeth that sit on either side of your lateral incisors. You can easily spot them by their distinctive cone-shaped appearance and prominent pointed tip.
To find your eye teeth, start from the very center of your mouth where your two front teeth meet. Count three teeth to the left and three teeth to the right—those pointed teeth are your eye teeth. This applies to both your upper and lower teeth, giving you four eye teeth in total.
The Exact Location of Eye Teeth
Where are the eye teeth located in your mouth? Eye teeth are positioned on both the upper and lower jaws, sitting between your lateral incisors (the teeth next to your front teeth) and your first premolars (the teeth behind them). You have four eye teeth total—two on top and two on the bottom.
The upper eye teeth are located directly beneath your eyes, which is exactly why they earned their unique name. If you draw an imaginary line straight down from the outer corner of each eye, you’ll find your upper eye teeth sitting right in that spot.
Upper Eye Teeth Position
Your upper eye teeth are the third tooth from the center of your mouth on each side. They’re the longest teeth in your entire mouth, with roots that can extend up to 17 millimeters into your jawbone. This impressive length makes them incredibly stable and strong.
Lower Eye Teeth Position
The lower eye teeth mirror the position of the upper ones but sit on your bottom jaw. They’re also the third tooth from the center on each side of your lower arch. While they’re still quite long, lower eye teeth typically have slightly shorter roots than their upper counterparts.
The Distinctive Features of Eye Teeth
Eye teeth stand out from your other teeth in several noticeable ways. Understanding these unique characteristics helps answer the question of which are eye teeth when examining your own smile.
Pointed Crown Shape
Unlike your flat incisors or grinding molars, eye teeth have a single, sharp cusp. This pointed shape resembles a cone or pyramid, making them easy to distinguish from surrounding teeth. The point, called a cusp, is designed specifically for tearing and gripping food.
Longest Roots in Your Mouth
Eye teeth hold the record for having the longest roots of any teeth in your mouth. The upper eye teeth, in particular, can have roots extending nearly 17 millimeters into your jawbone. This exceptional length provides incredible stability and strength.
Strategic Positioning
Eye teeth sit at a crucial corner position in your dental arch. They form a transition between your front biting teeth (incisors) and your back grinding teeth (premolars and molars). This strategic location allows them to perform their specialized function effectively.
Upper Eye Teeth vs. Lower Eye Teeth
When determining which are eye teeth, it’s helpful to understand the differences between the upper and lower versions of these teeth.
Upper Eye Teeth Characteristics
The upper eye teeth are often more prominent and longer than their lower counterparts. They’re positioned directly below your eyes, which is how they got their interesting name. These teeth typically have a more pronounced point and play a significant role in your facial appearance.
Upper eye teeth often cause more concern when they don’t erupt properly because they come in later than most other teeth and may become impacted in the jawbone.
Lower Eye Teeth Characteristics
Lower eye teeth mirror the position of upper ones but tend to be slightly shorter and less prominent. They emerge earlier than upper eye teeth, usually around ages 9-10 for permanent teeth. While they’re still quite strong, their roots are typically a bit shorter than upper eye teeth roots.
Why Eye Teeth Look Different
The unique appearance of eye teeth isn’t just for show—it’s the result of millions of years of evolution and serves important purposes in your mouth.
Evolutionary Purpose
Our ancestors needed strong, sharp teeth for tearing tough foods like raw meat and fibrous plants. While modern cooking has made our diets softer, we’ve retained these powerful teeth. Many animals, particularly carnivores, have even more pronounced canine teeth for hunting and eating.
Developmental Biology
Eye teeth develop differently than other teeth. Their longer roots and pointed shape result from specific genetic instructions that guide their growth. This specialized development ensures they’re strong enough to handle the forces involved in tearing food.
How Eye Teeth Function in Your Mouth
Understanding which are eye teeth becomes more meaningful when you learn about their important functions.
Primary Food Processing
Eye teeth work as your mouth’s primary tearing tools. When you bite into an apple, sandwich, or piece of meat, your eye teeth grip and tear the food while your incisors help cut it. This teamwork allows you to break down food efficiently before your molars grind it up.
Supporting Your Bite
Eye teeth help distribute biting forces across your dental arch. Without them, the pressure from chewing would fall unevenly on other teeth, potentially causing damage or excessive wear.
Maintaining Smile Aesthetics
These teeth play a vital role in creating an attractive smile. They provide definition and structure to your smile line, and their presence helps prevent that sunken appearance that can occur with missing teeth.

Comparing Eye Teeth to Other Teeth Types
To fully understand which are eye teeth, it helps to compare them with your other teeth types.
Eye Teeth vs. Incisors
Incisors are your eight front teeth—four on top and four on bottom. They’re flat and chisel-shaped, designed for cutting food. In contrast, eye teeth are pointed and conical, made for tearing. Incisors come in first during childhood development, while eye teeth arrive later.
Eye Teeth vs. Premolars
Premolars sit immediately behind your eye teeth and have two points (bicuspid) rather than one. They’re wider and flatter than eye teeth, designed for crushing food. Premolars handle a combination of tearing and grinding, serving as a bridge between canines and molars.
Eye Teeth vs. Molars
Molars are your large back teeth with multiple cusps designed specifically for grinding food into smaller pieces. They’re much wider and flatter than eye teeth and handle the final stages of breaking down food before swallowing.
Common Questions About Eye Teeth
People often have specific questions when trying to determine which are eye teeth in their mouth.
Are Vampire Teeth the Same as Eye Teeth?
Yes! The “vampire teeth” you see in movies and costumes are exaggerated versions of eye teeth. Costume fangs are typically worn over the canine teeth because these are naturally the most pointed teeth in your mouth.
Can You Be Born Without Eye Teeth?
While rare, some people are born missing one or more canine teeth, a condition called hypodontia. This genetic condition affects tooth development and may require dental treatment to fill the gaps and restore function.
Do Eye Teeth Always Look Sharp?
As you age, eye teeth can wear down from years of use, making them appear less pointy. Grinding your teeth at night (bruxism) can also flatten the cusps. Some people naturally have less pronounced points on their canines due to genetic variations.
Eye Teeth Problems and Solutions
Knowing which are eye teeth helps you identify potential problems that might require dental attention.
Impacted Eye Teeth
Sometimes eye teeth don’t emerge properly and become stuck in the gum or bone. This happens more frequently with upper eye teeth and may require orthodontic treatment to guide them into position or surgical exposure to help them erupt.
Misaligned Eye Teeth
When there isn’t enough room in your mouth, eye teeth might erupt in the wrong position—sometimes high up on your gums or even emerging behind other teeth. Orthodontic treatment with braces or clear aligners can move them into proper alignment.
Worn or Damaged Eye Teeth
Because eye teeth handle significant force when tearing food, they can chip, crack, or wear down over time. Dentists can repair damaged eye teeth with dental bonding, crowns, or other restorative treatments.
Taking Care of Your Eye Teeth
Once you know which are eye teeth, you can give them the special attention they deserve.
Proper Brushing Technique
Pay special attention to brushing around your eye teeth, especially where they meet the gums. Use gentle circular motions and make sure to clean all sides—front, back, and the chewing surface. The pointed shape means food particles can get trapped in unique spots around these teeth.
Flossing Around Eye Teeth
Don’t skip flossing around your canines. The spaces between eye teeth and neighboring teeth can harbor bacteria and food debris. Use proper flossing technique, gently sliding the floss up and down against each tooth surface.
Protecting from Injury
Eye teeth are prominent and vulnerable to injury during sports or accidents. If you play contact sports, wear a properly fitted mouthguard to protect all your teeth, especially these important canines.
Eye Teeth Development Timeline
Understanding when eye teeth appear helps you track normal dental development in children and recognize potential issues early.
Baby Eye Teeth Eruption
Primary (baby) canines typically emerge between 16 and 23 months of age. Upper baby canines usually appear around 16-22 months, while lower baby canines come in slightly earlier, around 17-23 months.
Permanent Eye Teeth Eruption
Permanent canines replace baby canines at different times. Lower permanent eye teeth typically erupt between ages 9-10, while upper permanent canines are among the last front teeth to appear, usually between ages 11-12.
Late Eruption Concerns
If permanent eye teeth haven’t emerged by age 13-14, consult your dentist. Late eruption might indicate impaction or other developmental issues that need professional evaluation and possible treatment.
Cultural and Historical Significance
Throughout history, people have noticed eye teeth and attributed special significance to them.
Historical Beliefs
In the past, people believed that problems with upper eye teeth could affect vision because of their proximity to the eyes. While modern medicine has disproven this connection, the historical belief influenced the name “eye teeth.”
Idioms and Expressions
The phrase “give your eye teeth” means you’d sacrifice something valuable for something you want badly. This expression recognizes how important these teeth are—you wouldn’t give them up unless something was extremely valuable to you.
Conclusion
Now you know the answer to which are eye teeth—they’re your four canine teeth, positioned as the third tooth from the center on both upper and lower jaws. With their distinctive pointed shape, longest roots, and strategic positioning, eye teeth play crucial roles in tearing food, supporting your bite, and maintaining facial structure. By understanding which teeth are your canines and how to care for them properly, you can ensure these important teeth remain healthy and functional throughout your life. Whether you call them eye teeth, canines, or cuspids, these remarkable teeth deserve recognition and proper care.
