04 How we work

What happens when you come to the clinic

  1. You tell us what you need

    Call or message us on WhatsApp and say what is bothering you or what you would like to change. There is no form to fill in.

  2. The dentist asks about you

    You are asked about your health, medicines, allergies and earlier dental work, because they can change what is suitable.

  3. Examination and X-rays

    The dentist examines your teeth and gums and takes X-rays, and a 3D scan (CBCT) where needed, at the clinic.

  4. Your options are explained

    You hear what the dentist found, what each option involves, how long it takes and what can go wrong, including the choice to leave things as they are.

  5. Treatment, only when you agree

    Nothing starts until you have agreed. A review afterwards shows how things have settled.

05 Quality

What the ISO 9001:2015 certificate means

The clinic's quality management system is certified to ISO 9001:2015 for oral health care procedures and treatment.1

ISO 9001 is a standard for quality management systems. ISO does not issue the certificates itself: outside certification bodies audit an organisation and issue them.1

The certificate shows how the clinic manages its processes. It does not measure how any one treatment turns out, so it is one thing to know about the clinic and not a promise about your result.
