Dr Alex Carruthers

Graduated from University of Manchester 2014

Dentistry has been a big part of Alex's life for a long time, having worked as a qualified dental nurse from leaving college and continuing her pathway to becoming a dentist.

Working alongside dentists in various specialities including endodontics, facial aesthetics, smile make overs, oral surgery and implantology has given her more passion and drive to pursue her career and excel as a dentist.

Since graduating she has worked as part of NHS and Private dental care in the North West. She believes in delivering dental care with empathy, passion and to the highest quality and standard.

Her main focus with any dental experience is to make people smile with confidence and remove the negative emotions associated with visiting the dentist.

She is a firm believer in building a complete experience for a patient from start to finish, whether it is simple treatment or full smile make overs. She has a passion for the artistry of dental work especially the use of composite and porcelain to provide smile make overs, restorative work and high end aesthetic treatment. Alex provides short term orthodontics using  different systems – both fixed metal braces and removable clear aligners. She has a passion for endodontics and would like further her career with post graduate education in this field over the next few years.
