Square Jaw

Singaporeans can have square jaws that detract from their ideal look. The good news is that Gentle Smile Dental Studio can help you create pleasant contours on your face.

What makes an ideal jawline?

A square jaw generally refers to the lower jaw bone jutting out on the side.

Those who are born with a strong jawline, naturally have a shorter face length, and square chin and could require masseter reduction surgery.

While some individuals are confident of their strong facial structure, some individuals, especially women, with square jaw may dislike it, and can’t wait to get rid of the excess bone jutting out (the angle between the chin and the neck that causes noticeable facial discordance of the female face, which is associated with masculine facial appearance).

Exceptions To The Rule

A few examples of Hollywood celebrities with very prominent square jaws are Lucy Liu, Cameron Diaz and Angelina Jolie. Despite Jolie’s strong jawline, she is still highly-regarded as one of the most well-known and popular artistes of all times. Just think of what’s an action movie without Jolie!

Three Causes Of Square Jawline?

Genetics

Asian men and women tend to have more square-shaped jaws

Diet and habits

Eating hard or chewy foods will cause jaw muscle growth

Overnight tendencies

You might be clenching or grinding at night, causing your jaw muscles to grow.

​Square Jaw to V-Shape Treatment

Square jaw reduction reduces the width of the lower part of the face, especially if it is caused by the lower jaw bone and the surrounding masseter muscle.

The masseter muscle is a strong and thick rectangular-shaped muscle (performing the primary function of chewing) that wraps around the side of the lower jaw and causes a powerful elevation or contraction of the lower jaw.
