Our Practice

Situated on a quiet street in the heart of Chelsea, our practice was founded in 2017 by Dr Anna Maciag, who is a Consultant in Oral Surgery with many years of experience in dental implants.

It is the result of a year-long effort to transform an empty and rundown traditional Georgian townhouse into an elegant dental clinic.

Anna Maciag is a Brilliant Dental Surgeon. The combination of Anna and Ovaldir Junior is unbeatable! Three years ago I had a tooth implant (100% success) Last month I returned to have two difficult back teeth extracted. I was DREADING IT! No Problem. No Pain. I insisted in not having antibiotics.

I can highly recommend the Chelsea Green Practice after a difficult but successful wisdom tooth extraction. Professional, skilful, kind and approachable team. The procedure was well explained with lots of detail on my request and I felt very reassured. Dr Anna Maciag and Ovaldir Cavargo made it bearable with their confident approach and human touch.
I've been trying to write this review for a while but it has been difficult to find the right words to express my feelings. I went to see Dr Anna Maciag a year ago at the her previous surgery where she used to work. My dentist referred me to see her, after I had been told by another specialist in oral surgery that he couldn't do anything for me, except to suggest another denture. I had a crown that needed to be replaced or removed, and also...

To ensure the safety and wellbeing of patients and staff, we have decreased patient scheduling, acquired full PPE and enhanced disinfection protocols. We look forward to welcoming you back to the new 'normal' practice of dentistry.

What to expect when you visit the practice:

Appointment times
Please come to your appointment on time and not before. Please do not come to the practice if you don't have an appointment scheduled. Simply call our reception team for help, advice or to book an appointment.

Cold/Flu/Covid-19 symptoms
Please reschedule if you or anyone in your household has had Covid-19 symptoms in the last 2 weeks.

Cancel appointments if you cannot attend
Appointment times are precious. If possible please cancel them at least 48h prior if you cannot attend so we can offer the appointment to someone else.

Temperature check & hand disinfection
All patients will have their temperature taken on arrival; you will then be asked to disinfect your hands prior to your appointment.

Face mask
You will be asked to wear a face mask on entering the practice and a mask can be provided on arrival.

Attend alone if possible

Less patients in the practice
We will book longer appointments than needed which will allow for enhanced cleaning and disinfection between patients. This will mean we will see fewer patients then normal in a day so please bear with us as we try to see you all.

PPE for staff
