The Truth About Teeth Shape: Rounded Teeth vs. Square Teeth

January 05 2022

When most people consider their smile, they first think of their enamel shade, alignment, and spacing. However, tooth shape is also crucial to the appearance of your smile and the functionality of your mouth.

Do Round Teeth vs. Square Teeth Affect Personality Traits?

While the meaning of tooth shape has not been scientifically studied, many believe that the shape of your teeth can indicate certain factors of your personality. For example, round teeth are said to be indicative of youthfulness, gentleness, and even femininity. This could be since as teeth wear with age, they become more sharp, blunt, and less rounded. For this reason, rounded teeth are more common among younger individuals.On the other hand, square teeth supposedly convey ambition, drive, and self-discipline or self-control. 

Do you find this to be true or false for you and your friends and family? Leave us a comment below to let us know!

 Functions of Round vs. Square Teeth

Now that you’ve learned more about the personality traits that may be associated with different teeth shapes, let's look at the functions round vs. square teeth perform for you and your health!

Round Incisors and Canines 

Adults have eight incisor teeth and four canine teeth. Incisor teeth are located at the front of the teeth and typically have a flattened end for cutting through food. Canines, also called cuspids, are the longest teeth and are located at the front corners of the mouth. Cuspids can be identified by their length and relatively sharp tips designed to tear through food. Both incisors and canines are visible when you smile, so it’s crucial to keep these teeth bright for a glowing smile. 

Square Molars and Premolars

Molars and premolars are the more square teeth in the mouth. Every adult has 12 molars, including four wisdom teeth and eight premolars, also called bicuspids. Molars are situated at the back of the mouth and grind and pulverize food before it is swallowed. They have a larger surface area and relatively blunt tops with grooves and ridges to soften food. Premolars, or bicuspids, are located at the sides of the mouth, between the canines and molars, and transition from the tearing function of the canines and the grinding and pulverizing function of the molars.  

Because premolars and molars are situated in the back of the mouth and are more tightly packed together, they are more susceptible to plaque build-up and decay. Be sure to floss regularly, use a deep cleaning gum repair treatment, and schedule twice-annual dental visits to keep your premolars and molars in excellent condition.

Whatever Their Shape: Take Care of Your Teeth

Your smile is a message to the world and has the power to connect you with others. Your smile speaks volumes about you, from your age and health to your personality and emotions. Whatever their shape or size, it’s imperative to take care of your teeth. To keep your pearly whites strong, healthy, and bright, brush twice daily with fluoride toothpaste and a soft-bristle toothbrush, followed by gentle flossing. For added whitening, consider implementing an at-home whitening routine with GLO Science Brilliant at-home whitening device that effectively whitens teeth with zero sensitivity.
