No business is without risk, but dentistry is notoriously a low-risk profession. This is partly why the banking sector is so supportive of dentists.
That said there is always a concern that a change to the NHS funding structure could negatively impact the viability of a dental practice. if a change were to take place this would be introduced over a period of time and whilst the funding system has changed the patients still require dental care and will be looking to practices for alternative solutions.
If the NHS funding structure was no longer deemed viable there will be the opportunity to provide a fee scale which is comparable with the NHS funding structure that is currently in place. This would then become a communication exercise to educate patients about the care they will be receiving and how this would benefit them.
