How Long Does Masseter BOTOX® Take to Show Results?

Woman getting masseter BOTOX in McLean, VA If you’ve been considering masseter BOTOX® for jaw slimming or relief from teeth grinding, one of the first questions you may have is: When will I actually see results? Understanding the treatment timeline helps set realistic expectations and ensures you know what to look for in the weeks following your injections.

The Immediate After Effects

Right after your masseter BOTOX appointment, you won’t see any visible changes. The treatment works by loosening the masseter muscles, the strong jaw muscles responsible for chewing and clenching. BOTOX takes time to block the nerve signals that cause these muscles to contract, so patience is key.

The First Week

During the first three to seven days, you may notice subtle improvements. For patients treating teeth grinding or jaw tension, the initial benefit is often a sense of relief as clenching starts to decrease. However, visible changes in facial contour typically aren’t noticeable just yet.

Two to Four Weeks

Most patients see the full effects of masseter BOTOX within two to four weeks. By this point, the masseter muscles have relaxed enough to soften the appearance of a square jawline, creating a slimmer, more contoured look. If your primary goal is pain relief or reduced grinding, this is also when the most significant improvements become clear.

How Long Do the Results Last?

Once the results appear, they generally last four to six months. With consistent treatments, the masseter muscles may gradually shrink from lack of overuse, leading to even longer-lasting jawline slimming.
