Is it ok to talk lot and laugh after getting Botox/Dysport in my masseters? (Jaw muscles)

Yes, you can laugh and talk after Botox to the masseter muscles. It will not impact your results. The treatment is done in the office with final results seen after two weeks. The effects will gradually fade over three to four months and should help with your teeth clenching. See an expert injector to learn more.

Please keep laughing!
Your masseters are “muscles of mastication” or chewing, and these do not affect your ability to move your face or smile. Since they are not the strongest muscles of mastication, Botox doesn’t effect ability to chew either. Masseter Botox may lead to a narrowed appearance on front view if they are large. Hope this helps! Dr Joseph

You should absolutely continue to live your life and enjoy it to the fullest. Botox is only a tool that is used to decrease the amount of dynamic wrinkles and your smiles are not going to make it work any worse. I hope this helps and good luck from York city plastic surgery
