Looking for a slimmer, more sculpted jawline without going under the knife? You’re not alone. At The Spiegel Center in Newton, Massachusetts—just outside of Boston—more and more people are opting for Masseter Botox, a non-surgical treatment that helps define the jawline while also offering real relief from jaw clenching and teeth grinding.
And when it comes to this treatment, one name stands out: Dr. Onir, New England’s most loved injector. She performs all of our Masseter Botox procedures and is known for creating natural, beautiful results that never look “done”—just refreshed.
What Is Masseter Botox?
Masseter Botox targets the thick, square-shaped muscles on either side of the jaw—called the masseter muscles—which help you chew and clench. In some people, these muscles are naturally strong or have become enlarged over time from frequent grinding or jaw tension (aka TMJ symptoms).
By injecting a small amount of Botox into these muscles, the area softens over time. The result? A slimmer lower face, reduced jaw tension, and often fewer headaches. It’s quick, virtually painless, and requires no downtime.
This treatment is sometimes called Jawtox—a clever nickname for masseter Botox that’s growing in popularity across Boston and beyond. Whatever you call it, it’s an easy, effective way to refine your facial shape and feel more comfortable at the same time.
Why It’s So Popular Around Boston?
People around the Greater Boston area—especially in Brookline, Cambridge, and Newton—are loving Masseter Botox because it fits into busy schedules and delivers meaningful results without surgery.
Here’s what makes it such a hit:
- It’s fast – The entire appointment with Dr. Onir takes about 15 minutes.
- It’s effective – Most people see noticeable slimming in just 2 weeks!
- It’s versatile – Great for aesthetic refinement and for jaw tension relief.
- It’s subtle – Results develop gradually, so people just notice that you look good.
At The Spiegel Center, we’ve treated countless patients with Masseter Botox—from people looking to soften their jawline to those managing TMJ symptoms or even migraines. The treatment is customized for every face, because your features—and goals—are unique.
Why Dr. Onir?
At The Spiegel Center, we believe who performs your injection is just as important as the product itself. That’s why Dr. Onir—our experienced aesthetic injector—is the one who performs all of our Masseter Botox (Jawtox) procedures.
She’s known for her artistic eye, gentle technique, and deep understanding of facial anatomy. Whether you're looking for a more heart-shaped face or relief from clenching and tension, Dr. Onir will tailor the treatment specifically for you. It’s not just about injecting Botox—it’s about creating harmony in your facial features.
Can You Combine It With Other Treatments?

- Chin filler or chin augmentation for added balance
- Jawline contouring with filler for sharper definition
- Skin tightening treatments to address laxity in the lower face
