Botox lasts about 3 months, and can be longer if repeated

Botox generally lasts about 3 months. If repeated in the same area(s), it can last longer. Dysport (a new botulinum toxin) is now available and can last a little longer (about 4-5 months).

Botox for a gummy smile

Gummy smiles are treated with several units, you might need 2 units on each side but the doctor may need to give more or less. It needs to be repeated and may only last two or three months, sometimes longer. Anywhere that Botox is used near muscles that move a lot, such as when eating and speaking, the activity returns to normal more quickly.

BOTOX Cosmetic

Dear Brian, Botox can be used to treat the strong muscles that lift the upper lips when you smile- this will give the effect of less gum show when you smile. the average dose is 4 to 6 units. sometimes this needs to be adjusted to achieve the desired results. Botox generally lasts 3 to 4 months and can be repeated or stopped without any problems.

With Warm Regards,

Botox lasts 3-4 months for gummy smiles

Botox sure makes a big difference when you have a gummy smile but only lasts 3-4 months at a cost of $350 each time. Dysport might be worth a try since it may last longer by about a month at the same price.

Gummy Smile & Botox

The results will last for 4 months. With repeated usage it might last as long as 6 months. The dosage is about 5units of Botox Cosmetic in the nasolabial angle (where upper lip and nose meet in the center) and 3units each in the right and left side of the nose where the nose groove meets the cheek (alar groove).

Strict dosage measurement is essential or you can have smiling, speaking and swallowing issues.
