Gummy smile treatment in Lisbon

Cosmo Clinic Team

Gummy smile treatment in Lisbon is a non-surgical procedure used to reduce the appearance of excessive gum exposure when smiling. By injecting botulinum toxin into the muscles responsible for lifting the upper lip too high, the treatment gently relaxes the area and helps achieve a more balanced, natural-looking smile.

At Cosmo Clinic in Lisbon, gummy smile treatment requires precise anatomical assessment to determine the correct injection points and dosage. Our doctors take time to evaluate each patient's smile dynamics before proceeding. Because a gummy smile correction relies on the same facial muscles as other botulinum toxin treatments, many patients combine it with a lip flip for added upper-lip balance, or address crow’s feet in the same visit; you can review the full range of botulinum toxin treatments with our medical team. Effects typically last three to four months.

FAQ

A gummy smile is when too much of the gum line is exposed while smiling, often due to hyperactive upper lip muscles.

By relaxing the elevator muscles of the upper lip, botulinum toxin limits how high the lip rises, reducing gum exposure.

Results are temporary, typically lasting 3 to 4 months, and can be maintained with routine sessions.

No – your smile remains natural, just more balanced and aesthetically pleasing.

The injection involves a small volume at a precise point near the base of the nose. Most patients describe it as a quick pinch. No anaesthetic is required.

Results begin to appear within 3–5 days and reach full effect at 2 weeks. The reduction in gum exposure becomes visible when smiling within this window.

Gummy smile treatment typically lasts 3–4 months. With regular maintenance, the muscle tends to respond progressively, and intervals between sessions may extend over time.

Yes. Many patients benefit from both — botulinum toxin reduces gum exposure while lip filler adds volume and definition to the upper lip. Your doctor will assess which combination, if any, is appropriate for your anatomy.

What is gummy smile treatment

Gummy smile correction is an aesthetic medicine treatment in Lisbon aimed at those who expose more than 3 millimetres of gum when they smile. Botulinum toxin type A is applied at specific points near the base of the nose, targeting the levator labii superioris alaeque nasi muscles. By relaxing this musculature, the upper lip covers more of the gum line when smiling, bringing the smile into a more balanced and natural proportion.

Who is it for

Best suited to those whose gummy smile is caused by upper lip hyperactivity, the mechanism that responds most predictably to botulinum toxin. Where the cause is skeletal or dental in origin, orthodontics, gingivoplasty, or maxillofacial surgery may be a better path; a consultation with our medical team distinguishes the underlying causes. Contraindicated during pregnancy, breastfeeding, and in neuromuscular disorders.

What to expect from the session

During the consultation, smile dynamics are carefully analysed, the elevation of the upper lip and the proportion of gum exposed are both assessed. Botulinum toxin is then applied at 1 to 2 points on each side, near the base of the nose, using an ultra-fine microneedle. The session takes 10 to 15 minutes, and you can return to your routine immediately.

Results timeline

Initial changes begin between day 3 and day 5 after treatment. Full effect stabilises between days 10 and 14, with the upper lip covering more gum when smiling. Average duration is 3 to 4 months, shorter than other applications, due to the high activity of the muscles in the mid-face. A follow-up review consultation is scheduled after treatment.

Aftercare

For the first 4 hours after the session, avoid lying down or bending the head forward. During the first 24 hours, skip intense physical exercise, saunas, and very hot baths. Throughout the first week, avoid massaging the treated area, postpone facial treatments, and apply sunscreen whenever you are exposed to the sun.

Why Cosmo Clinic
