Dr James Critchley

BDS (Wales) 2000
GDC No. 77511

Dr James Critchley is an enormously experienced restorative dentist with over 15 years in practice in and around Cheltenham providing family, implant 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 worlds top cosmetic dentists.

His post graduate training is still focused on spending time directly with the worlds 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, straightening teeth using invisible orthodontic aligners, and dental implants.

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