Physician-Led Neuromodulators
Masseter Botox for Jaw Slimming and TMJ in Lutz, FL
Concierge, physician-administered masseter Botox to soften a wide jawline and relieve clenching and TMJ tension. Dr. Espinet treats you personally at your home or office across Tampa Bay.
How It Works
Relaxing the muscle that defines your jaw
Masseter Botox is injected into the masseter muscles, the large muscles along the jaw that power chewing and clenching. Relaxing them gradually slims a wide or square jawline for a softer facial contour, without surgery.
Because the masseter is also involved in grinding and clenching, the same treatment can relieve TMJ tension and reduce teeth grinding (bruxism). Results develop over a few weeks as the muscle relaxes, and like all neuromodulators the effect is temporary, so periodic maintenance keeps results consistent.

Anatomy, in Plain English
Meet your masseter, the muscle behind a square jaw
Place your fingertips on your cheeks, about an inch in front of your earlobes and just above the corner of your jaw, then clench. The firm bulge you feel is your masseter, one of the main muscles that close your jaw when you chew or clench.
Like other muscles, it can grow with heavy use. Nighttime clenching, grinding, or constant gum chewing can thicken it and widen the lower face, and genetics play a part too. A neuromodulator quiets the nerve signal to the muscle, so it contracts with less force and gradually becomes smaller.
It does not change bone. If your jaw is wide because of the jawbone itself, masseter Botox will do less, and Dr. Espinet checks for this first.
Know Your Goal
One muscle, different reasons to treat it
Jaw slimming
An aesthetic goal: a softer, more tapered lower face. It takes weeks, because the muscle has to get smaller.
Clenching and grinding
A comfort goal. Relaxing the masseter lowers the force behind bruxism, which may mean less morning tightness and jaw fatigue.
TMJ tension
Jaw-joint pain has many causes. When an overworked masseter is part of it, easing the muscle may relieve tension. Painful clicking, locking, or a recent injury needs evaluation by your dentist or doctor first.
Both at once
One treatment can address both, with dose and placement adjusted to your priority.
Teeth Grinding and TMJ
Botox for teeth grinding and TMJ: what it can and cannot do
Masseter Botox works on the muscle side of clenching and grinding. It lowers how hard the masseter can contract, which may ease tightness and fatigue. It does not realign your bite, repair worn teeth, or fix a problem inside the jaw joint itself, such as a displaced disc. Research on Botox for TMJ disorders is mixed, so it is one option to discuss with Dr. Espinet, not a first step for every kind of jaw pain.
A night guard from your dentist protects your teeth but does not stop the muscle from clenching, so some people use both. Dr. Espinet is a physician, not a dentist, and does not fit night guards or treat tooth wear. If your teeth are cracked or worn, or your jaw clicks with pain or locks, see your dentist or doctor first.
Not sure whether you clench? These common signs are worth mentioning at your consultation:
- A sore, tight, or tired jaw when you wake up.
- A dull ache at the temples, often in the morning.
- Teeth that feel sensitive, or edges your dentist says look worn or flattened.
- A partner hearing you grind at night.
- Catching yourself clenching during the day, at a desk or behind the wheel.

Results Timeline
Relief comes first, jaw slimming follows
Relief depends on the muscle relaxing; slimming depends on it shrinking, which takes longer.
| Timeframe | Clenching, grinding, TMJ tension | Jaw slimming |
|---|---|---|
| First week | The effect starts to build; you may notice a softer bite. | No visible change yet. |
| About 2 weeks | The muscle-relaxing effect is usually near its peak. | Little to see. The muscle has relaxed but not slimmed. |
| 4 to 8 weeks | Relief holds steady. | A slimmer contour starts to show. |
| 3 to 6 months | Relief often fades first, a signal to plan your next visit. | Slimming fades more gradually. |
Typical patterns, not promises. Results vary with muscle size, dose, and habits.

Aftercare
Masseter Botox aftercare, kept simple
Dr. Espinet gives you aftercare instructions at your visit. Typical guidance focuses on keeping the product where it was placed while it settles. More tips: how to get the most from your treatment.
- No rubbing, massage, pressure, or jaw stretches for 24 hours.
- Stay upright for about four hours.
- Skip strenuous exercise and saunas until the next day.
- Ask Dr. Espinet before booking a facial or massage that works on the jaw.
- Eat normally; choose softer foods if your jaw tires in the weeks ahead.
Maintenance
How often to repeat masseter Botox
Treatment is commonly repeated about every three to six months at first. With consistent treatment, some can space visits further apart because the muscle stays smaller between sessions. Dr. Espinet plans the timing with you. Interested in early lines too? Ask about preventative Botox.
Safety
Side effects, and who should hold off
Botox, Xeomin, and Jeuveau are FDA-approved neuromodulators, though using them in the masseter is off-label (see the FAQ below). Most masseter side effects are mild and temporary.
Common and short-lived
Tenderness, a small bump or bruise, or a mild headache, usually settling within days.
Chewing fatigue
For a few weeks, tough or chewy foods can tire the jaw sooner. Everyday meals are usually fine.
Uncommon
Uneven results, a temporary change in your smile, or a bulge in an untreated part of the muscle. Rarely, the effect can spread beyond the treated area; get medical care right away for any trouble swallowing, speaking, or breathing.
Who should hold off
Wait if you are pregnant or breastfeeding or have an infection over the jaw. A neuromuscular condition such as myasthenia gravis, or a past allergic reaction to a neuromodulator, may rule treatment out. Share all medications, including certain antibiotics and muscle relaxants.
Very lean faces or looser skin
In an already slim face, reducing the masseter can look hollow, and where skin along the jaw is looser, a smaller muscle can make that laxity more noticeable. Dr. Espinet may suggest a lower dose, or advise against treatment if the trade-off is not worth it.
For Men
Masseter Botox for men
Men often have larger, stronger masseters, and many are more interested in relief from clenching or jaw tension than in slimming. A defined jawline is usually something to keep, not soften.
Dr. Espinet tailors dose and placement to ease clenching while aiming to keep definition at the jaw angle. Larger muscles often need more units, as the cost table shows. For frown or forehead lines, see Botox in Lutz.

FAQs
Masseter Botox questions
Does masseter Botox actually slim the jaw?
Yes. By relaxing the masseter muscle, the jaw gradually softens over several weeks for a slimmer, more contoured look. The effect builds with treatment and is maintained with periodic sessions.
Can masseter Botox help with clenching and TMJ?
Often, yes. The masseter drives clenching and grinding, so relaxing it can relieve TMJ tension, jaw fatigue, and the headaches associated with bruxism.
How long do results last?
Neuromodulator results are temporary and typically develop over a few weeks. Periodic maintenance treatments keep the slimming and relief consistent over time.
Is masseter Botox safe?
At MeliOra every treatment is performed by a physician, Dr. Espinet, who evaluates your anatomy and uses conservative, precise dosing. Botox, Xeomin, and Jeuveau are FDA-approved neuromodulators.
How much does masseter Botox cost?
Neuromodulators start at $12/unit for Botox, Xeomin, and Jeuveau. Masseter treatment uses more units than fine-line areas, so final pricing is set during your consultation.
How many units of Botox do you need for masseter?
Commonly cited ranges are about 20 to 30 units per side for jaw slimming, or 40 to 60 total, with strong clenchers sometimes needing more. These are illustrative estimates, not a quote. Dr. Espinet sets your dose after examining the muscle while you clench, at $12/unit for Botox, Xeomin, or Jeuveau.
How long does it take for masseter Botox to work?
The muscle usually starts to relax within the first week, and the effect is often near its peak by about two weeks. Visible jaw slimming takes longer, typically showing between four and eight weeks, because the muscle has to get smaller. Results vary from person to person.
Does masseter Botox hurt?
Discomfort is usually brief and mild: a quick pinch at each injection point. The masseter is a thick muscle that typically needs only a few points on each side, so the treatment itself is short. Some tenderness at the injection points for a day or two is normal.
What are the side effects of masseter Botox?
The most common are tenderness, a small bruise, or a mild headache, which usually settle within days. Some people notice chewing fatigue with tough foods for a few weeks. Uncommon effects include uneven results or a temporary change in the smile. Rarely, the effect can spread beyond the jaw; get medical care right away for any trouble swallowing, speaking, or breathing.
Will masseter Botox make it hard to chew?
Usually not for everyday meals. For a few weeks after treatment, tough or chewy foods such as steak, crusty bread, or gum can tire your jaw sooner than usual. This tends to ease as you adjust. Choosing softer foods during that stretch helps, and Dr. Espinet can lower the dose next time if it bothers you.
Can masseter Botox change your smile?
It can, but it is uncommon. If the product affects a nearby muscle that pulls the corner of the mouth, your smile can look slightly uneven until the effect wears off, which is temporary. Careful placement in the lower, thickest part of the masseter, clear of the smile muscles, helps lower that risk.
Can masseter Botox cause sagging jowls?
It does not loosen the skin, but it can make existing laxity more noticeable in some people, because the muscle beneath the skin becomes smaller. This matters most with looser skin along the jaw or an already slim lower face. Dr. Espinet assesses your skin and facial structure first and may suggest a lower dose or advise against treatment.
Is Botox FDA-approved for TMJ or teeth grinding?
Botox, Xeomin, and Jeuveau are FDA-approved neuromodulators, but as of October 2026 none is FDA-approved specifically for the masseter, TMJ, or teeth grinding. Using them there is off-label, which is common and legal when a physician judges it appropriate. Dr. Espinet explains what that means for you at consultation.
Do I still need a night guard if I get Botox for teeth grinding?
Often, yes. A night guard protects your teeth from wear, while masseter Botox reduces how hard the muscle clenches. They work on different parts of the problem, so many people use both. Keep your dentist involved, especially if you have worn or cracked teeth.
What happens if I stop getting masseter Botox?
Nothing harmful. The effect wears off gradually, the muscle regains its strength and size over several months, and your jaw returns to its previous shape. Clenching relief usually fades before the slimming does. You can restart after a consultation with Dr. Espinet.
Can I get masseter Botox at home in Tampa?
Yes. Dr. Espinet performs masseter Botox as a house call at your home, office, or event across Hillsborough, Pasco, and Pinellas counties, including Tampa, with no travel fee. Select in-person appointments are also available at the Lutz office. Call or text (813) 726-5808 or book online.
