IOWC - Interdentale Online World Congress

6 – 7 December 2023 - Live Stream from the DMG Dental Training Center Hamburg

Spotlight on: Aesthetic management of demarcated enamel opacities – Science based strategies for your daily practice.

Clinical management of aesthetically impairing vestibular lesions can be somewhat cumbersome in daily practice. Minimally invasive strategies to improve aesthetics are today’s intervention of choice. Due to the heterogeneity of the lesion’s origin, their clinical manifestations show big variation and thus need an individualized treatment plan.

If you find it challenging to manage these lesions in your daily practice, we are here to support you in daily clinical decision making.

The first edition of the Interdentale Online World Congress will take place from 6 – 7 December 2023, in a live stream broadcast from Hamburg.
Mark this day in your calendar and make sure, you don’t miss this unique event!

14:00 – 17:00 Uhr

Dr Linda Greenwall a 3rd generation dentist, born in Cape Town, South Africa. Graduating from Witts Dental School in 1984, moving to the UK in 1985 to continue widening her field of dentistry. 

After completing my Masters research into tooth whitening and discovering a passion for minimally invasive dentistry I wrote 4 textbooks on the subject, my first book has been translated into 5 different languages. 

In 1989 I started my lecturing career and have been all over the world presenting my knowledge and scientific research on tooth whitening and minimally invasive dentistry. 

In 2011 I decided I wanted to give back to dentistry and the community by establishing the Dental Wellness Trust, a non-profit Charity, focussed on raising dental awareness, improving oral health and dental wellness in less fortunate children and communities. This is mainly achieved through training, educating and introducing innovative supervised tooth brushing programmes, which has been called LiveSmart. LiveSmart is helping over 20,000 children in the townships of South Africa and over 20,000 in nursery and school children in UK. 

In 2017 I was awarded a British Empire Medal (BEM) for my services to Dentistry. This was present by Lord-Lieutenant of Greater London, Sir Kenneth Olisa OBE and attended the Queens Garden party in June 2018 to celebrate this accolade. 

In 2020 I worked with a group of female dentists whom wanted to improve the work balance for female dentists. We set up an organisation called Women Dentists Network, to support female dentists. 

This has been accomplished whilst running a multi-disciplinary, Private Specialist Dental Practice in London, continuing to lecture both in the UK and Internationally, undertaking research, writing books, dental articles, editing a journal, and raising four sons, one whom followed in her foot steps to become a dentist. I am also a proud grandmother to two grandchildren.
