I have a gummy smile. How long do I need to notice any change?

 It will likely take 5 to 7 days before your Botox starts working, don't pass any judgment on its final effect until at least 14 days. 

Botox
does not work immediately. It will take 3-5 days for it to start working
and it will have max effect 7 days after injection.  It is normal that you do not appreciate a change at this time. I hope this helps.

Thank you for your
question in regards to botox and your gummy smile. Botox can take up to 7-10 days for full correction. After this point is i best to have a follow up appointment with the provider who performed your botox injections to assess if more botox is needed. To be sure, see two
or more board-certified providers in your area for a complete evaluation to
make sure you are a good candidate and that it is safe for you to have
treatment.

I hope this helps.
