What are the accurate areas for Botox injection to treat gummy smile? And units required for?

There are several muscles that elevate the lip but the Alaeque nasi is the muscle that should be injected to reduce a gummy smile. The injection point for this muscle is located just lateral to the nose. I usually inject 2-3 units of Botox at the initial visit and have patients return in one week to reassess. In some patients, a few additional units of Botox can be injected. It is better to inject this area in small increments. Good luck.

This is difficult to answer without pictures. The treatment for gummy smile is ~2 injections points at very low doses. Results will last 3-4 months. Best, Dr. Emer.

This treatment can't be done without affecting your smile.  Folks really do not like the effect no matter how great the doctor thinks they are.  The so-called gummy smile is a big beautiful smile.  It is not an abnomality that needs to be treated.

As a woman I totally understand the importance of well contoured lips and smooth skin!
As a dermatologist, I can tell you that "around the mouth" can include different injection methods to achieve different results. Some injections can decrease wrinkles around the mouth (smoker lines), treat gummy smile, downward angles of the mouth and so on.

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!

Thank you for your question. Botox injections
for a gummy smile are done at the nasolabial fold into the levator labii
superioris alaquae nasi muscle. Typically this takes about 1-3 units per side. However,
this is an advance technique and must be done by an expert injector. Best of
Luck!

Usually a couple of injection sites on each side of the upper lip are treated with a couple of units of Botox each. Exact placement and dosing will vary depending on the individual's needs.

An experienced injector will know where to place the botox for this issue and I would recommend starting with about 4 units.  You can always add more if it's not enough and everyone has a different threshold for how much is too much.  A great treatment for those bothered with the gummy smile.  Best.

Hi there, great question. Gummy smile is the excessive gingival show in the top teeth during smile. By weakening the muscles that elevate the upper lip with botox, the lip will lift less when you smile. Typically use 6 to 8 units and place the injection at the junction of the side of your nose and the top of the nasolabial fold. Good luck with your injection! Go to an experienced injector for this treatment as it is a more advanced injection

I have done this many times without affecting the smile.  the material should be placed at the pyriform sulcus and under the tip of the nose--total only 6 units

To treat a Gummy Smile a small amount of Botox can be used just under the nose.  I would start with 2 units on either side.  That would relax the muscle that is causing the upper lip to be pulled upwards.  Another 2 units can be added on either side if necessary.  Regards, Dr. D.
