Can Someone Intentionally Chew Gum To Increase The Size, Girth, and Squareness Of Their Jaw Angle?

Many people get BOTOX injected into their Jaw Angle to narrow a wide jaw appearance, or even reduce the harshness / squareness of their jaw angle, by relaxing the masseter m. Square jaw angles or a wide jaw appearance is very common in the Asian population, perhaps due to teeth grinding, TMJ, or maybe genetic. Since teeth grinding creates hypertrophy of the masseter muscle, couldn't someone intentionally chew gum to increase the size, girth, and squareness of their jaw angle ?

Probably Yes!

This is a fascinating question, and good for you for asking. We like to be challenged and give some opinions where we have not done clinical trials but may offer some insight. The answer to your question is probably yes; and as with others, if this is not done symmetrically which is often hard when chewing gum, you may end up with more problems than you bargained for. And if you chew too hard, other medical conditions can occur, which would be unfortunate for you when we can use our toxins to do what you want much more simply.

Botox for narrowing wide jaw, chewing to increase jaw?

Very interesting question.  The simple answer is that one could intentionally chew gum to increase the size, girth and squareness of the jaw, but as noted in other answers posted here, one would want to do this symmetrically.  The problem I see however is that the constant chewing motion could set you for temporomandibular joint TMJ syndrome.  So to solve one perceived problem, one might gain a new problem.  (This answer is not intended nor implied to be a substitute for medical advice.

Can you chew gum to make your jaw more square

The answer is sort of. You'd have to be very specific about how you chewed the gum - same number of chomps on each side, same amount of force, etc., same amount of time each time. It'd be like a workout, and frankly, you're going to have a very sore jaw and mouth. There was a question on here awhile back from a woman who said she chewed gum every day, but only on one side of her mouth, and her face showed some serious signs of asymmetry that she wanted to correct. So yes, working out your jaw muscle is possible. Working it out and making it look good, even, and symmetrical, probably not.

Chewing to increase bulk of the masseter muscle

The siple answer is yes but there is also a genetic predisposition and anatomic reasons to develop hypertrophy of the masseter muscles. But chewing will keep them large and not chewing will help reduce their bulk.

Chewing gum to increase masseters

The masseter muscle can respond like any other muscle.  With exercise and exertion, the muscle can grow.  So chewing gum should contribute to growing the muscle.    If, however, you are trying to expand the jawline for aesthetic concerns (e.g. you are worried that you face is too thin), then I would consider treatments like Sculptra to enhance the jawline.  I would seek a consultation with someone who is an expert at non-surgical shaping of the jawline with the use of Botox/Dysport to narrow the jawline or Sculptra (or other fillers) to redefine the jawline.

Building up masseter muscle

That would make sense, as you can build up the muscle in a similar way as any other muscle in your body. However, it would be difficult to predict by how much you could build up the muscle and if it would achieve a symmetric result.

Botox and masseter muscles

I'm not sure why someone would want to excessively "chew" to increase the size of the masseter muscle as it would be exceedingly taxing on the joints. The masseters aren't the only muscles involved in chewing - the temporalis is also included.

Creating intentional masseter hypertrophy

Just like any muscle in your body, with repetitive and continuous use it will increase in strength and bulk.
