I had botox injected into my masseters for jaw reduction and to stop my clenching and grinding two days ago. I don't see or feel any change yet. Can you tell me when I can expect to notice any changes and what they might be? The doctor said I should probably come back in 9 month's time for more injections but I don't know how much botox he used, he injected at 4 sites on both sides.

Timeline for masseter injection
1) botox injection
2) within 2 weeks, you should feel that your muscles can't clench down as hard
3) Over the course of the next many weeks, the masters will slowly shrink and your face will slowly slim. This is due to the muscle atrophying as a result of not working as hard (analogy: if you have your arm in a cast for a few weeks, it will be smaller than the other arm when the cast comes off).
People normally notice reduction in grinding/clenching and less discomfort/tension within the first couple weeks. The changes in facial shape are more gradual.
Botox and Masseters Muscle
Most of my patients begin to see and feel the effects within two weeks. That muscle is extremely strong and so it does require a bit longer than the forehead muscles to fully react. It will get better, but you should start noticing things changing within a few weeks. You will notice a lessening of the tension in that muscle and less of the strain. I usually see people back within 6 months, especially ones I treat for TMJ, because they can start feeling the Botox wearing off about that point and I prefer they don't get back to baseline again, and so do they!

Muscle thinning in the masseters for teeth clenching may take a while after Botox treatment
Usually Botox injected in the masseter muscles can minimize teeth clenching, not grinding. After the clenching diminishes, the muscle starts to become less hypertrophied, or bulky. Just like a weight lifter who stops working out; the muscles are still going to be bulky for a while. There is a gradual diminishing of girth.
Botox and Dysport for masseter reduction, "V-line"
You won't see a change until about 7-10 days. Depending on the dosage used by your physician, and where in the body of the masseter muscle he injected, the degree of "tapering" and change will vary. Typically 4-5 injections are performed on each side along the inferior border of the muscle, but taking the injections more superiorly does help to enhance the final result. The Botox will have worn off in 3-4 months, so 9 months is too long to wait for a repeat injection. Even with the largest muscles you will see a visible reduction in size with proper technique after one injection, though you may not achieve the maximal reduction possible with Botox until you have had 2-3 sessions.
Give the Botox a few more days to take affect for relief and results
Hi and great question! Botox does take a few days (7-14 average) to take affect and it is not concerning yet that you haven't noticed change. Always be confident that you can follow up with your provider after 2 weeks if you aren't noticing relief or affect. Dosage is commonly communicated in our practice for patient education purposes, but it's a benefit to you and your provider to have excellent communication so the appropriate dosage is administered. I also agree that 9 months seems a lengthy distance between appointments as the Botox will commonly wear off 3-4 months following treatment. There are patients who do see longer effects with treatment, but once you get the first concern out of the way- being certain that the Botox is dosed appropriately and you have results you're pleased with- it will also benefit you to assess yourself 3-4 months from now. With repeated treatments of Botox, the muscles do not have the opportunity to gain full strength and go back to "pre-treatment" state. This is true of dynamic muscle activity anywhere Botox is effective. Again, it's too early to worry about the treatment you just received, but don't ever hesitate a follow up to the office 14 days following treatment if you're unsatisfied with the results. Sometimes a few more units are needed and it's best to not overtreat initially. It's also not a good idea to assess too early, or before the 2 week period. I hope this brings confidence in the treatment and helps you to know experiencing little change thus far is very normal.
BOTOX Cosmetic takes a week to work
BOTOX Cosmetic is a great treatment for overactive muscles, but takes an average of 7 days to see an effect. You should notice some weakness in the muscle at that point, although a decrease in muscle size can take several treatments spaced 3 months apart. It is normal not to notice any change at 2 days. If you still don't have the effect you want at 2 weeks, follow up with your doctor so he/she can see how you responded to the treatment, and make any adjustments needed. Best of luck.
Botox for masseter hypertroophy treatment
Masseter hypertrophy treatment with Botox requires multiple treatments before seeing a true effect( flattening of the muscle). Yes, the Botox starts working in one to two weeks, but it may require several treatments over a year's period to see some thinning.
