Delivering quality orthodontics for everyone







At Marsh House Orthodontics we offer a team of highly skilled specialists who are trained in the latest orthodontic techniques and appliances to transform smiles.

If you are looking for an orthodontist in London, then we welcome you to our Mitcham-based practice where you can benefit from the latest brace systems such as Invisalign clear aligners or ceramic braces, as well as more traditional appliances such as fixed metal braces.

We treat all of our patients on an individual basis, tailoring treatment plans to meet each patient’s exact needs and implementing teeth straightening treatments that make it possible to smile, talk and eat with more confidence. Our experienced team is also on hand to share advice and tips on braces care to make treatment as comfortable and easy as it can be.

We provide private orthodontic treatment to our own patients and those referred by a dentist and also offer NHS assessments for children and young people under the age of 18. Whether you are looking for adult braces or want to discuss orthodontics for your child, our comfortable, welcoming practice and friendly team await your first visit.

What our patients say


A delightful experience

"The staff here at Marsh House Orthodontics are always welcoming, friendly and professional. I’m almost done with my treatment and I’m extremely happy with my results so far. My experience with orthodontic treatment has been smooth sailing and overall a delightful experience thanks to all of the amazing staff here."


Very happy with my treatment

"Absolutely the most fantastic orthodontist I’ve been too. Staff are super friendly and supportive which was so nice as I’m a student and would often ask me how I’m doing or help me book appointments convenient for my time schedule. Left feeling very happy with the outcome of my treatment. No cons at all. Great orthodontist!"


Great results and amazing service!

"Absolutely the friendliest, most accommodating dental or orthodontist practice I’ve encountered. They will always try and fit appointments around your schedule, friendly staff at reception invariably greet you with a smile. Appointments run on time and the orthodontists and dental technicians are fantastic. Great results and amazing service! Would definitely recommend."


First class service

"My whole experience from start to finish has been a pleasurable one. Dr Williams and his team made me feel at ease and my treatment was explained to me at every stage. I spoke to Laura or Karen who were always at the end of the phone and always happy to answer any of my questions however small. The surgery was always clean and tidy and the staff were always so friendly. I would recommend this practice to anyone thinking of having brace treatment. First class service."


The best experience

"The best experience. As a nervous twenty-something looking to get braces, I didn't have a clue where to start. I had a sit down consultation with Laura who was so kind and helpful and I knew right away I would be going ahead with the treatment. I looked forward to my appointments to get my braces tightened as the staff are so reassuring and invested in your 'journey'. Cannot recommend Marsh House enough!"


I can't stop smiling

"I have just had my braces taken off today and feel so happy with the result. I cant stop smiling. The staff there are so lovely and helpful and have always been so reassuring, talking to me and explaining everything that they are doing to make me feel calm and as relaxed as possible. Really lovely and very clean place. Would definitely recommend them."
