Masseter Botox in Colombia — For Jaw Clenching and a Softer Jawline
The masseter is the muscle you clench with. When it is overactive — from bruxism, stress or habit — two things tend to happen: the jaw aches and the lower face widens as the muscle thickens. Botulinum toxin relaxes it, which eases the clenching and, over months, softens the squared look. It is a medical treatment with an aesthetic side effect, not the other way round. Cartagena, with consultation days in Bogotá and Medellín.

- WHAT IT IS
What masseter Botox does, and what it treats
Botulinum toxin type A partially blocks the nerve signal that tells the masseter to contract. The muscle does not stop working — you keep chewing normally — but it stops clenching with the force it was using, especially at night.
Two effects follow. The functional one comes first: less jaw pain, less morning tightness, less grinding. The aesthetic one comes later: as an overworked muscle is used less, it gradually loses volume, and the lower third of the face softens. That takes weeks to months, not days.
- BENEFITS
What masseter Botox can do for you
Relief from clenching, and a softer jawline as the muscle relaxes.
Less clenching
Reduces the force of grinding, especially at night.
Quick procedure
15 to 20 minutes. You can go back to your routine straight away.
No surgery
Minimally invasive, with micro-needles. No operating room.
Softer lower face
As the overworked muscle reduces, the squared jawline softens over months.
Ultrasound guidance
The muscle is measured and the parotid gland located before injecting.
Relief in 1–2 weeks
The functional effect on clenching appears within days to two weeks.
- WHO IT IS FOR
Two reasons patients ask for it
Patients arrive with one of two problems — and often with both.
Jaw pain and clenching
Morning jaw tightness, temple headaches and grinding at night.
A squared lower face
Widening of the lower third when the masseter is overdeveloped.
Tooth wear
Enamel wear your dentist has flagged, often the first sign of bruxism.
Poor sleep quality
Night-time grinding that disturbs sleep, yours or your partner’s.
Asymmetry
One side stronger than the other — more common than most people expect.
After orthodontics
Persistent clenching that continues after dental treatment.
- STEP BY STEP
How your treatment is done, step by step
A four-step protocol: quick, controlled and precise.
Assessment and ultrasound scan
Dr. Vives examines the masseter at rest and clenched, and runs an ultrasound scan to measure its thickness and locate the parotid gland, which sits right beside it.
Treatment plan
The number of units and the injection points are set for the size of your muscle and for whether the goal is mainly functional, mainly aesthetic, or both.
Precise placement
Botulinum toxin is injected into the body of the masseter, at a depth confirmed by ultrasound so it goes into the muscle and not into the surrounding tissue.
Follow-up
A check-up at 15 days reviews the response. If one side is stronger than the other — which is common — it is balanced then.

Dr. Jorge Vives Gutiérrez
Radiologist and aesthetic physician. The masseter sits directly against the parotid gland, and the difference between a good result and a lopsided smile is the plane the product lands in — which is exactly what ultrasound shows.

- FAQ
Frequently asked questions about masseter Botox
The questions international patients ask most about masseter Botox.
How much does masseter Botox cost in Colombia?
Masseter Botox in Colombia is priced by the number of units, which depends on the size and strength of your muscle. The exact quote is given at the assessment consultation. International patients can request the equivalent in US dollars before traveling.
How many units do I need?
It depends on the size and strength of your masseter, and it differs between sides in most people. Undertreating wastes the session; overtreating weakens chewing. That is why the muscle is measured with ultrasound rather than dosed from a standard chart.
How long does it last?
The functional relief from clenching usually appears within 1 to 2 weeks and lasts around 4 to 6 months. The change in facial shape is slower: it builds over 2 to 3 months as the muscle reduces, and it holds longer with repeated sessions.
Does it hurt?
Very fine needles are used and the injection is quick. Most patients describe a small pinch. Chewing may feel slightly tired during the first week while the muscle adjusts.
Am I a candidate for masseter Botox?
It suits people who clench or grind their teeth, wake with jaw or temple pain, have been told by their dentist that they are wearing down enamel, or whose lower face has squared off from muscle overdevelopment. It is not the answer if the width of your lower face is bone rather than muscle — and that distinction is one an ultrasound assessment can actually make.
How often do I need to repeat it?
Usually every 4 to 6 months at first. With repeated sessions the muscle stays reduced for longer, and the interval between treatments tends to stretch.
Why does Dr. Vives use ultrasound for the masseter?
Because the masseter lies immediately next to the parotid gland, and toxin that spreads into the wrong plane can affect the muscles used to smile. Ultrasound lets Dr. Vives measure the thickness of your muscle, confirm the needle is inside it and stay clear of the gland. It also shows whether the two sides are actually the same size — they usually are not.
Can I see Dr. Vives in Bogotá or Medellín?
Yes. Dr. Vives is based in Cartagena, where he sees patients on a regular weekly schedule at his practice in Bocagrande. He also travels to Bogotá and Medellín on scheduled dates each month and sees patients at a partner clinic in each city, following the same assessment protocol.
Botox is assessed and treated in the same visit in all three cities, so a single scheduled date is usually enough.
Because Bogotá and Medellín are consultation days rather than permanent offices, dates are confirmed before you travel. Request the next available date through the form and we will confirm the city and the date with you. If you are traveling from abroad, you can also start with an online consultation before booking your trip.
