He qualified with a Bachelor of Dental Science from the University of the Witwatersrand in 2003.

His community service year was spent at Ngwelezane Hospital near Richards Bay. There he helped launch the Nseleni Clinic, part of the hospital's outreach programme. Setting up a clinic from nothing taught him more about running dental care than any lecture had. The need was real and the resources were few.

Before FresherBreath, he co-founded a distribution business supplying retail chain stores, and ran it alongside clinical work.

He decided in 2009 to commit to dentistry properly. During the exit he found the business had been stripped of assets, and was encouraged to walk away without paying suppliers. He settled every creditor himself instead.

That decision is worth knowing about, because it explains how the practice is run. He returned with an MBA from Wits Business School, completed with distinction and two Dean's commendations. A clinic is a system to be designed, not a room to be filled.

He founded FresherBreath in 2005. It began as a single practice and grew into a group across Johannesburg. The Braamfontein dental concept store opened in 2012. It was built on one idea. A dental practice should feel approachable rather than clinical.

A child, a teenager and a patient in later life do not need the same care. So the practice is organised around the stage you are in, rather than a menu of procedures.

You can see it in how the site is arranged. Whether you want to repair, straighten, replace or maintain your teeth, you start from what you want to change.

His clinical interest is how breathing, facial growth and jaw function affect each other. He is listed with the South African Airway and Myofunctional Society.

A child who breathes through the mouth grows a different face from one who breathes through the nose. The jaw develops narrower and the teeth crowd. Sleep is often disturbed long before anyone connects it to the mouth. Straighten those teeth without addressing the breathing, and they drift back.

This is why our assessments look at more than teeth. Breathing, tongue position, swallowing and posture all get checked, because they are what shaped the problem in the first place.

Dr Mansoor was central to establishing Myobrace in Southern Africa, and FresherBreath runs a dedicated Myobrace programme in Johannesburg.

Myobrace treats the habits behind crooked teeth in children rather than forcing the teeth into line. It fits his view of the work exactly. Find the cause, then treat it.

He lectures to other dentists on the system, on myofunctional rehabilitation, and on how practices can work across disciplines instead of in isolation.

He is a director of the TMJ and Sleep Therapy Centre of South Africa. It belongs to an international network of centres treating craniofacial pain and sleep-disordered breathing.

The work overlaps with FresherBreath directly. Patients arrive with jaw ache, headaches, worn teeth or a snoring complaint from a partner. The cause is often the same set of factors. Grinding and jaw joint pain are treated here as symptoms of how the system is working, not as isolated complaints.

• Vice-Chairman of the South African Dental Association, and a director on its board
• Chair of the SADA Audit and Risk Committee
• Member of the SADA Dental Practice Committee
• Founding President of the Young Dentists' Council of South Africa, 2013 to 2015
• Represented the profession at FDI World Dental Federation congresses in Turkey and India

He has served on the SADA Dental Practice Committee since 2013, including negotiating funding with medical aids on behalf of the profession.

Wits Business School named him one of the 50 Faces of WBS in 2018, and featured him again in its fiftieth anniversary series. Destiny Man named him in its 30 Under 30 in 2010. Black Business Quarterly gave him a Corporate Youth Award in 2009, the same year he was admitted to Golden Key Honour Society. The Impumelelo Awards recognised him as an Emerging Black Entrepreneur in 2008.

He holds directorships outside dentistry too, in property and in the dental supply sector. Those sit alongside the clinical work rather than replacing it.
