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 (also known as jaw 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).

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.

Square Jaw Reduction Process
You can’t totally fight genetics, but you can improve the appearance of your jawline through surgical or non-surgical procedures.

Surgical
Surgical treatment will involve removing the excess bone and/or muscles.
They include:
- Jaw surgery
- Masseter reduction
- Chin shaving surgery
Non-Surgical
Non-surgical treatments to reduce a square jaw include:
- Braces or clear aligners
- BTX (Botox)
- Nightguard
Cost and Timelines
BTX (Botulinum Toxin or Botox) for square jaw reduction will be from $300-$500 (before GST) depending on the dosage required.
Repeated treatments may be required for non-surgical treatment as the results typically last 3-6 months. Our dentist will make a clinical assessment and customise the most appropriate procedure for you depending on your needs.
