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.

Typically Botox will take 1-2 days to show an effect, and you will experience the complete effect in 1 week.  By the end of this week you should notice that your gums do not show as much while you smile.  It is always possible to add a little additional dosage at that point as needed to titrate the effect.  

It can take up to two weeks to see your final result from Botox injections. Most patients begin to see some effect five to seven days after treatment. The effects will gradually wear off typically over three to four months.

As a woman I totally understand the importance of well contoured lips and smooth skin!
As a dermatologist, I can tell you that different anatomy in each patient make me decide on whether I combine Botox (how much and exact placement) with deciding to add fillers to balance thin lips that pull up in gummy smiles. Together they two can create a very natural contour and very sexy appearance - if done correctly.

Botox can take up to 2 weeks for full effect. Fillers on the other hand are immediate in their effect but can temporarily get "swollen" and go back down to normal volume!
The key is to make sure you communicate what you are trying to achieve and ask specific questions from the doctor as the risks for that treatment.
I do many gummy smiles and they can be successfully treated with Botox/Dysport when performed by expert injectors. Injection of a low dose into precise points on the upper lip to reduce the “gum” showing without affecting any other motion. I have my patients smile several times, and animate their face as they are talking to me during the consultation. Where exactly I place it (and how much product) depends on the anatomy of the patient.
Factors to consider include how thin/thick the upper lip is (and if you use fillers on the upper lip you need to consider balancing the lower lip to avoid the "duck lip" tragedy!). How much the lips are pulled up and how many millimeters of gum are exposed. Any asymmetries during movement or at rest will also have to be taken into account.
I think the key is the consult to show you in the mirror what to expect. In this case Botox/Dysport may lower the upper lip so that you are not be able to show the gum line when you smile.  Because there is some risk of lowering too much, (which could affecting your singing or playing of a wind instrument, for example), using low doses and making sure that you receive precise injections by a highly qualified and certified professional are very important!
Best of luck!

As effective as BOTOX is for a
number of conditions, including a gummy smile, it does take a bit of time for
the results to appear. In most cases, my patients start seeing changes about 5
days after their treatment. If you haven't noticed any results more than 7 to
10 after your treatment, get in touch with your injector. Thanks for your
question!

Botox takes 7 to 14 days to see the full effect.  Your physician should have explained that the results are not immediate. Keep us posted on your results.  Best, Dr.  Green

Hi Naser78Thank you for your question.  Botox usually takes effect between 5-7 days.  Give it time to settle in.  Hope this helps.  Best regards

Botox is an effective treatment for fixing a gummy smile. However, like all other Botox treatments, the effect of therapy is not immediate, nor would it be seen 1 day post-op. Change after Botox typically takes 1-2 weeks to set in.
