What is masseter Botox and who benefits most?
Masseter Botox relaxes the chewing muscle at the angle of the jaw. It is helpful if you have a wide or square lower face from muscle bulk or if you clench and grind with muscle tenderness.
How does jaw Botox slim the lower face?
By reducing overactive contractions, the masseter gradually looks less bulky. This reveals a softer jawline over several weeks while keeping normal function for eating and speaking.
Will masseter muscle Botox help TMJ pain?
It may reduce muscle-based tension and tenderness related to clenching and grinding. It does not treat joint disorders inside the TMJ itself. Many patients pair Botox with an oral appliance for full care.
How many units are typical for masseter muscle Botox?
Dosing is customized to your muscle size and goals. Many aesthetic plans start around 20 to 40 units per side with onabotulinumtoxinA equivalents, then adjust at follow up.
How soon will I see a slimmer jaw after Botox on masseter?
Most people feel less tension in 1 to 2 weeks. Visible contour change is easier to see at 8 to 12 weeks when the muscle has thinned.
How long do jaw Botox results last?
Results often last 3 to 6 months. You can maintain the look with periodic touch-ups planned around your schedule and goals.
Will masseter Botox make chewing difficult?
Some people notice temporary chewing fatigue or a softer bite. This usually improves as the muscle adapts. Plan softer foods the first week if you are concerned.
Can jaw Botox change my smile or make it uneven?
This is uncommon with expert mapping and depth control. Your injector uses a safe zone and balanced points to protect nearby smile muscles.
What should I avoid before and after jaw Botox?
Avoid alcohol, blood-thinning supplements, or unnecessary NSAIDs for 24 hours before and after if your doctor approves. Skip heavy chewing, jaw massages, and facials on treatment day. You can return to normal routines the next day.
Can I work out after masseter Botox?
Light activity is fine. Many providers suggest waiting until the next day for high-intensity workouts to reduce swelling and bruising risk.
Can I get masseter Botox if I wear Invisalign or have crowns or implants?
Yes. Dental work does not prevent treatment. If you clench more during orthodontic movement, Botox may help reduce muscle tension. Tell your provider about all dental appliances.
Is masseter Botox permanent?
No. The effect gradually wears off as nerve signals recover. With consistent care, the muscle may maintain a leaner profile over time.
Can I combine masseter Botox with other treatments for a sharper profile?
Yes. Common pairings include chin or jawline filler for shape, skin tightening for definition and oral appliances to protect teeth. Your plan is customized to your anatomy.
What is the difference between masseter Botox and jawline filler?
Masseter Botox slims muscle. Jawline filler adds structure. Some patients use both. Botox reduces width. Filler defines angles.
