Dr. David Gwyer

Meet our award-winning Team » Dr. David Gwyer

Dr David Gwyer graduated from Cardiff University in June 2009. David has worked in both private and NHS practices in South Wales before moving to Ireland in the summer of 2011.

David is an enthusiastic patient dentist, who is focused on providing high quality dental care to all patients in an environment in which they feel totally at ease.

He is interested in all aspects of general and cosmetic dentistry and keeps up to date with any advances available in modern dentistry. He is particularly interested in treatment involving crowns, bridges, implants and dentures and the treatment of patients with any dental anxieties.

David has successfully completed an intensive yearlong training programme under renowned implant surgeons Dr Mark Diamond and Dr Pearce Stinson. As a result David has now added placement and restoration of implants to his repertoire of treatments. He is able to restore all types of situations, from single spaces or broken teeth to full mouth cases. David continued his education in implantology by reading for a master’s degree in dental implantology through the university of Bristol. Under the guidance of internationally acclaimed implant surgeon Jonathon Schofield and his faculty David is at the cutting edge of implant treatmentmand training to use advanced techniques such as digital impression taking, computer guided implant placement and management of failing implants. 

As a member of SAAD (society for advancement of anaesthesia in dentistry) David has a rapidly expanding list of nervous patients. David feels that dentistry should be accessible to all patients; no matter anxious or challenging their individual needs are. David is trained to use various types of sedation to cater for different levels of anxiety and is happy to offer this to any patients who feel they need a little more help to have treatment completed.

David is also heavily involved in a new programme in Ireland known as the Sleep Clinic. The Sleep clinic provides treatments for patients who suffer with snoring and obstructive sleep apnoea.

Recently David has been granted the prestigious honour of being appointed a trainer to newly qualified dentists taking their first steps into general practice. This highly challenging role helps the newly qualified dentist to apply their skills in a safe and effective manner whilst assessing their competence to perform specific treatments.

Outside of work David is a dedicated family man and is enjoying the new challenges of being a Dad to his son Sean and his imminent new arrival. He is an avid Manchester United fan and tries to attend games whenever possible.

David has quickly established an enviable reputation in the area for his excellent work and caring approach to adults and children. He is currently accepting new patients to his list and is able to offer FREE consultations for any of his specialist interest skills.
