What Makes a Smile ‘Gummy’?
A gummy smile is when a larger portion of your gums shows when you smile, often making teeth appear shorter than they are. While it’s typically harmless, many people feel self-conscious about it. At Harley Street, we offer advanced treatments to gently reshape the gum line and enhance the natural balance of your smile, helping you feel more confident every time you laugh or grin.

Laser Gum Contouring
Laser gum contouring is a fast, gentle treatment designed to reshape your gum line and enhance your smile. It’s best for patients with excess gum tissue that makes teeth appear shorter or results in a “gummy” smile. Using advanced laser technology, we carefully remove the extra tissue, sculpt your ideal gum shape, and instantly seal the area with no bleeding or stitches. The entire treatment typically takes between 60 to 90 minutes and involves minimal discomfort with no downtime, giving you immediate, natural-looking results.

Crown Lengthening
If your teeth appear shorter than you’d like due to excess gum or hidden tooth structure, crown lengthening can help reveal more of your natural smile. It’s best for patients with a short teeth appearance who want a more balanced and proportionate look. During the treatment, we gently reshape the gum and underlying bone to expose more of the tooth surface and create ideal contours. The results are permanent, and the entire procedure typically takes between 90 to 120 minutes.
- Dramatic improvement
- Long-lasting results
- Natural appearance
- Stable outcomes
Combination Therapy
Combination therapy is ideal for more complex cases where multiple factors affect the appearance of your smile. It’s best suited to patients needing a tailored solution that goes beyond a single treatment. Using a combination of advanced laser and surgical techniques, we take a comprehensive approach to address both gum and tooth concerns, delivering optimal aesthetics with highly personalised results. Treatment time is fully customised based on your needs, ensuring the best possible outcome.

I couldn’t be more pleased with my results with Dr Aneka. She answered all my questions and been there with me every step. She’s very good at making you feel calm and confident. I was quite terrified before when going dentist but all my visits and treatments were painless which make me gain my confidence back. I would give more than 5 starts if I could. Thank you Dr Aneka and Harley Street Studio’s team

I was a patient of Steffen Decker’s and underwent lingual orthodontics to straighten my teeth. From my very first consultation, I felt assured he was the best person for the job. To say I am a perfectionist when it comes to my teeth is an understatement and he really went over and beyond to ensure I had my expectations met. As well as being a phenomenal orthodontist and creating the smile I had always wanted, he made the whole experience a pleasure with his kind nature and great work ethic of always putting patients first. I would recommend him to everybody – I think you would be hard pushed to find somebody with greater passion than Dr Decker and he deserves every success that comes to him.

Everything You Want to Know
Will gum contouring hurt?
This procedure is remarkably comfortable. We use local anaesthetic and micro-surgical techniques to minimise discomfort. Most patients need only paracetamol afterwards, if anything.
How long do results last?
Crown lengthening and gum contouring provide permanent results. Once excess gum tissue is removed and healing is complete, your new smile line is stable for life with proper care.
When can I see the results?
You’ll see your new smile immediately after treatment! While there may be minor swelling for a few days, the dramatic improvement is visible right away.
What’s recovery like?
This treatment requires minimal downtime. Most patients return to work the next day. Avoid spicy foods for a week and follow our simple aftercare instructions.
Am I a good candidate?
If you show more than 3mm of gum when smiling, you’re likely a candidate. Dr Marruganti will assess your specific case and recommend the best approach during your consultation.
