A “gummy smile” is a broad label, not a single problem. For some people, it’s related to tooth size or the way the teeth and gums sit; for others, it’s lip shape, jaw position, or simply an upper lip that lifts strongly when they smile. Because the causes vary, the options vary too, and it’s easy to assume Botox is a universal fix when it’s actually most relevant in one specific scenario: an overactive upper lip muscle.

That’s why careful understanding matters. Botox for a gummy smile is a small, targeted treatment designed to relax the muscles that pull the lip upwards, so the lip sits a little lower when you smile. It’s quick, effects are not immediate (it can take around two weeks to fully settle), and results are temporary, commonly lasting a few months. Cost also varies, and the cheapest option is rarely the safest, as practitioner experience in this area is particularly important.

In this guide, you’ll learn what makes someone a suitable candidate, what to ask in a consultation, what the appointment and aftercare typically look like, and the main risks and side effects to be aware of, including the rare but serious ones that need urgent attention.

What Causes a Gummy Smile?

Several factors can contribute to a gummy smile. These include the way your teeth have grown and their size, the size of your lips, an overgrowth of your jaw, and a hyperactive upper lip.

Can You Get Rid of a Gummy Smile With Botox Treatment?

If the main cause of your gummy smile is hyperactivity of your upper lip, then anti-wrinkle injections could help. A gummy smile can be effectively corrected with Botulinum Toxin. It's a quick and simple treatment and a small amount of Botox can be placed strategically to reduce excessive gum showing.

Botox or other brands of botulinum toxin, such as Bocouture, Azzalure, Letybo and Nuceiva will relax the muscles causing hyperactivity so the lip is repositioned and hides your gums.

What Does Botox for Gummy Smile Treatment Involve?

If you have botulinum toxin injections to treat your gummy smile, then you can expect a quick (less than an hour) and pain-free procedure. You'll just feel a sharp scratch as the injections go in.

There may be some redness and swelling around injection points, but this will calm down after a few hours. Normal activity can resume immediately after treatment.

The full result of gummy smile reduction treatment usually takes two weeks to take effect and will last three to six months.

How Much Does It Cost to Treat a Gummy Smile With Botox?

Seeing someone with experience in gummy smile treatment is far more important than getting a cheap deal!

Gummy smile Botox (and wrinkle reduction botulinum toxin treatment in general) is a minimally invasive procedure and prices can range from £200 to £400, often depending on the clinic location and practitioner expertise.

Are There Side Effects to a Gummy Smile Correction With Botox?

Side effects from Botox and other brands of botulinum toxins are rare, but can include:

  • Headaches

  • Asymmetric smile

  • Swelling, pain and bruising around the injection site

  • Allergic reaction

  • Dry eyes or mouth

The most dangerous complications are double vision and difficulty breathing, but these are thankfully extremely rare.

If you experience any side effects or complications, contact your practitioner immediately.

Who Should You Trust for Your Gummy Smile Treatment?

Find someone with specific experience in treating gummy smiles. Lots of practitioners will use Botox for general lines and wrinkles, but won't be well-versed in injecting this area.

We highly recommend that you only undergo treatment with a medically-qualified professional, who will have undergone training in anatomy and physiology, as well as be accountable to a regulatory body such as the General Medical Council (GMC), Nursing and Midwifery Council (NMC), or General Dental Council (GDC).

They should also be able to advise you of the risks of injectable treatment and be confident in handling complications if they arise. Any issues should be discussed at your review appointment and further adjustments can be made to achieve your desired results if necessary.
