Dr James Critchley is an enormously experienced restorative dentist with over 24 years in practice. James works at Pittville Lawn and at other Portman practices around the UK, providing patients with all aspects of dental implantology, and cosmetic dentistry. James’ passion for dentistry started at an early age following his father who was one of the UK’s leading implant dentists. Such was James’ interest in dental implants that he started his post-graduate training before he had even completed his dental degree, spending time at the home of dental implants in Gothenberg Sweden. This was followed by time in America being mentored by some of the world's top cosmetic dentists. To date, James has completed 3,000 cases.

His post-graduate training is still focused on spending time directly with the world’s leading dentists in the fields of implant dentistry and cosmetic dentistry. This has meant James has built a particular reputation for his skill in restorative and cosmetic dentistry, including the all-on-four technique.

In 2005 James opened his own practice in Cheltenham, Pittville Lawn, before it became part of the Portman family in 2011.

When James is not at the practice, he spends his time with his family. His interests are anything outdoors from Rugby to skiing.
