So I've always had this jaw asymmetry where my right side is a little bit wider than the left. But it wasn't really noticeable - you'd have to consciously look for asymmetry to notice it in real life. In fact it is only when I started getting interested in human aesthetics, mewing etc. I noticed this asymmetry for the first time. I would classify it as minor and within norm - by no means very noticeable, deformed and so on.

I recently started chewing mastic and I noticed first signs of masseter hypertrophy within first 10 days. When I looked in the mirror one day the discepancy between jaws became very evident. You don't really need to look very hard to notice that - it instantly catches your attention. I stopped chewing as soon as I noticed that.

I made sure to chew evenly on both sides: 15 minutes each every day. But if masseter hypertrophy was equal on both sides then my original facial proportions would be preserved - am I right? The only explanation I see now is that my right side hypertrophied more - if you have any other ideas please let me know.

My teeth aren't perfect so I suspect that I might just need to use more force on my right side hence better hypertrophy (because of more "blunt" shape of teeth there as opposed to more "sharp" on the left side). Now I might be completely wrong but these are just my ideas for how it could have happened. When chewing on my left side I can feel my teeth crushing mastic gum with more ease as commared to the right and I noticed it since beginning and was worried about imbalances already.

I have no "scientific" way of proving uneven hypertrophy. When I clench my teeth and touch my masseter muscles then the right one seems more "firm" and the left one a little bit "softer" although the difference is slight. It can be just as well a result of autosuggestion and not really true - I'm just sharing my observations.

What do you think I should do? Concentrate on left side more? Or just chew on left side until I no longer have obvious asymmetry? Or stop chewing altogether? Or start using some device like Jawzrsize or so to make sure my development is even on both sides?

I know it's difficult to judge without photo but the level of masseter hypertrophy is very low as of now and it's barely visible on pictures. It's much more noticeable in "real life" and most of the time photos don't even manage to "catch it". I've been experimenting with different angles and distances and I picked photo which resembles my mirror reflection the closest. I attached it to this post. Just take note that it's not perfect representation of reality.

Any help will be much appreciated!
