How long does masseter Botox last?
Typically four to six months. As the effect fades the muscle gradually returns to its previous activity, so sessions are repeated to maintain the result. The two benefits also arrive on different schedules — the muscle starts relaxing within about two weeks and grinding relief usually comes first, while visible slimming takes longer.
The figure
Typically four to six months. As the effect fades, the muscle gradually returns to its previous activity, and sessions are repeated to maintain the result.
Two benefits, two timelines
This is the part worth understanding, because judging it too early gives the wrong answer:
- The muscle starts relaxing within about two weeks, and grinding relief usually comes first.
- Visible slimming takes longer, because the change in the jaw's appearance follows the muscle reducing in bulk rather than simply relaxing.
Someone treated primarily for jaw clenching may feel the benefit well before anyone can see one.
It is as much functional as cosmetic
Reducing the masseter's contraction force takes the power out of clenching and grinding. That is a real functional benefit, and for many patients it is the main one — which also changes how you judge whether it is time to repeat.
What should not change
Correctly placed, it should not change your smile — the masseter closes the jaw, it does not move the lips. Some chewing fatigue in the early weeks is recognised.
If your smile does feel different, that is a placement question and worth raising promptly rather than waiting for the effect to wear off.
Maintenance, and what it costs
Repeat sessions are the model here rather than a one-off. On cost, one thing matters more than the rate: Botox is priced per unit at this clinic — from ₹299 per unit — and the masseter needs considerably more units than typical wrinkle areas.
So a per-unit figure tells you very little about a masseter treatment. Ask for your estimated unit count and the total, and ask again at repeat visits, since the dose may be adjusted.
Judging when to repeat
Rather than counting months, notice what returns first — usually clenching or morning jaw tightness. That is a more useful signal than the calendar, and it is worth mentioning at your next appointment.
