Will Masseter Botox help me? (Photo)

Hey! I'm posting this mainly because I'm not really sure what I should do. I'm missing my second molar, and have been for the last few years. Because of this, my right masseter is larger than my left. I'm assuming it's because this side had to pick up all of the slack and because I grind my teeth a lot. I plan on getting an implant this year, but I’ve also been eyeballing masseter botox because I do suffer from TMJ. Will the tooth implant alone balance my jaw?
