Gummy smile

26 February 2026

A gummy smile means that relatively much gum is visible above the upper teeth when smiling. This can be perceived as cosmetically bothersome, even though it is usually medically harmless. The cause often lies in an overactive muscle in the upper lip, causing the lip to pull up too far when laughing.

A gummy smile can be treated in various ways, depending on the cause. In many cases, a Botox treatment is chosen that temporarily reduces muscle activity. Because anatomy, smile line and muscle strength differ per person, it is important to carefully compare treatments and clinics.

Gummy smile

In short: this is what you need to know about a gummy smile treatment

• A gummy smile is often caused by an overactive upper lip muscle
• Most chosen treatment: Botox
• Botox relaxes the muscle that pulls the lip upward
• Results visible within 3–14 days
• Effect lasts on average 3–4 months
• Treatment takes approximately 10–15 minutes
• Comparing helps with a natural and safe choice

Why results and experiences with a gummy smile treatment can differ

What can go wrong with a gummy smile treatment?

With a gummy smile treatment, something can go wrong if the dosage or injection site is not correct. Botulinum toxin reduces the activity of the muscles that lift the upper lip, but too high a dose can cause excessive muscle relaxation. This may result in the upper lip moving too little, leading to an unnatural smile or difficulty speaking and drinking. Asymmetry can also occur if muscle activity is inhibited unevenly. In rare cases, spread of the product to surrounding muscles can cause temporary changes in function.

How do you recognize a less successful gummy smile treatment?

A less successful gummy smile treatment usually results from incorrect dosage or injection placement. Botulinum toxin inhibits the muscles that lift the upper lip, but excessive or uneven relaxation can disrupt lip movement. This may cause the smile to become asymmetrical or the upper lip to hang too low during speaking or laughing. Insufficient correction can also occur if muscle activity is not adequately reduced. The result is then an unnatural smile or continued visibility of gum tissue when smiling.

How much Botox do you typically need for a gummy smile?

The amount of Botox varies per person and depends on the strength of the upper lip muscles and the degree of gum visibility. On average, low dosages are used, often between 2 and 8 units distributed over multiple injection points. More units do not automatically mean a better result; a subtle, customized dosage usually ensures a natural smile. During the consultation, the doctor determines what is appropriate.

When do you see the real result of a gummy smile treatment?

The real result of a gummy smile treatment becomes visible when botulinum toxin has sufficiently inhibited the signal transmission between nerve and muscle. This process takes time because the release of acetylcholine is gradually blocked. Visible muscle relaxation usually occurs within a few days, with maximum effect after approximately one to two weeks. The muscles that lift the upper lip then reduce their activity, making less gum visible when smiling. The final result is assessed once muscle function has fully stabilized.

What is the difference between a gummy smile treatment and a lip filler?

The difference between a gummy smile treatment and a lip filler lies in the mechanism of action and the target tissue. A gummy smile treatment uses botulinum toxin to relax the muscles that lift the upper lip, reducing gum visibility when smiling. A lip filler usually contains hyaluronic acid and adds volume to the lip tissue by attracting water and filling space in the connective tissue. Botulinum toxin therefore affects muscle activity, while a filler changes the shape and thickness of the lip. As a result, the indication, effect and treatment outcome differ.

What is a gummy smile treatment & how does it work?

Gummy smile treatment in brief
• Type of treatment: cosmetic / injectable
• Goal: less visibility of gum tissue when smiling
• Visible result: yes
• Average duration: 10–15 minutes
• Main success factor: correct dosage and precise placement

What does Botox do for a gummy smile?

Botox temporarily relaxes the muscle that lifts the upper lip (levator labii superioris). As a result, the lip rises less and less gum tissue becomes visible.

Is the effect of a gummy smile treatment permanent?

No. Botox works temporarily and must be repeated to maintain the effect.

When do you see results after a gummy smile treatment?

Usually within 3 to 14 days, with a check-up around two weeks.

Gummy smile

What can go wrong with a gummy smile treatment?

With a gummy smile treatment using botulinum toxin, mild side effects such as swelling, redness or sensitivity at the injection site may occur. Botulinum toxin inhibits the release of acetylcholine, causing the elevator muscles of the upper lip to contract less forcefully. With too high a dosage or incorrect placement, temporary reduced lip mobility or slight asymmetry may occur. These effects generally disappear as the neuromuscular blockade decreases.

How do you recognize a less successful gummy smile treatment?

A less successful treatment may present as limited mobility of the upper lip or an unnatural smile. This occurs when muscle activity has been inhibited too strongly. Excessive relaxation affects the balance between lip elevation and facial expression. As a result, smiling appears less dynamic.

How much botulinum toxin is typically needed for a gummy smile?

The required amount depends on muscle strength and the degree of gum exposure. Usually, 2 to 8 units are sufficient to subtly reduce lip elevation. A low, targeted dosage limits the risk of overcorrection. Therefore, precision is central rather than quantity.

When do you see the final result of a gummy smile treatment?

The effect develops gradually after injection. Botulinum toxin needs time to block signal transmission in the treated muscles. Around two weeks, maximum muscle relaxation is reached. The final result can therefore be assessed at that time.

Navdeep delivered outstanding service - she thoroughly explained each step clearly during my consultation ensuring that I was comfortable to proceed with the treatment. She also made me feel very relaxed during the procedure which was great because I hardly felt any pain when she was injecting the Botox. I am so happy with the results. My new smile has given me a significant confidence boost, and I look forward to returning as a customer in the future. Show less »

The gummy smile treatment that Julia prescribed for me has been a game changer. After a few doses of botox in that area, the muscle memory has been completely re-written. I feel much more confident.

The building itself is absolutely gorgeous (it feels like you’re going to a luxury spa) and everyone there can’t do enough for you (opening doors, asking how your day was, offering drinks).

Faye who I had my treatment with was beyond amazing. She is so kind, approachable and knowledgable, and when I let her know I was a bit nervous, she was so considerate. Faye understood exactly what I wanted, and I couldn’t be happier with my treatment. I’ve had so many compliments and I could honestly cry at how much it has improved my confidence - I feel amazing!! I’ll be recommending Dr Ed Robinson aesthetics and Faye to everyone I know as her work is amazing! Show less »

Gummy smile treatment compared with alternatives

Botox vs lip flip

A lip flip also affects the upper lip, but is less focused on reducing gum visibility than a specific gummy smile treatment.

Botox vs dental correction

With a gum or jaw structure issue, a dental procedure may be more suitable.
