Gilles Derry - GDC registration no: 54888

I qualified from Guy’s Hospital Dental School in 1980. I gained experience of dental practice in Northampton and Peterborough before joining Triangle Dental in 1984. I became a partner in 1986.

I enjoy all aspects of dentistry and offer my patients a wide range of treatments and am particularly interested in cosmetic dentistry. I enjoy the challenge of solving complicated dental problems and working closely with my patients to achieve the best possible results using the latest techniques.

I believe strongly in the prevention of dental disease. All my patients have regular appointments with our hygienists to help keep their teeth and gums in good health. Teeth should look good and feel good!

I have undertaken many postgraduate courses to keep my dentistry up to date including a year long course at the Eastman Dental Institute in advanced techniques and the Diploma in General Dental Practice. In the last year, I have undertaken 12 days of postgraduate study.

And finally . . .

I am married to Lesley who works for the British Dental Association in
London. We live in Chieveley and have recently gutted and refurbished our house. We are keen gardeners and are struggling to tame an overgrown garden. We keep chickens.

Brian Holmes - GDC Registration No: 57810

I am a graduate of the Queens University Belfast Dental School. Since Qualifying I have continued to develop my dental knowledge by being involved in post-graduate dental education.

In 2005 I was awarded a Diploma in Postgraduate Dental Education by the University of Bristol. I am currently a member of a dentistry study club.

The replacement of missing teeth is an important aspect of dentistry. It is extremely satisfying to me to see the difference having a smile restored can make to a person both in terms of confidence and appearance. Removable prosthodontics (ie the making of dentures) is something that I particularly enjoy. Dentures come literally in all shapes and sizes and are individually made to suit the denture wearer. Denture teeth look very realistic and the improvement in appearance can be fantastic. Denture bases can be made from a variety of materials including metal (very strong); acrylic (looks very natural), and flexible nylon (very retentive). The design of each denture is very important in order to best suit the needs of the individual.

Other methods of replacing missing teeth that I find interesting include bonding to adjacent teeth (ie ‘sticky bridges’) as this minimises the impact on the supporting tooth.

Recently I have become interested in dental implants as a means of replacing missing teeth. Dental implants can be used to help support dentures or individual crowns or bridges. Because a dental implant is attached securely to the jaw bone, and implant-supported restoration is the closest thing to having a natural tooth.

Since joining Triangle Dental in 2001 I have appreciated the Triangle Practice Philosophy of ‘maximum prevention’ (of dental disease) and I enjoy working closely with our team of dental hygienists and dental health educators.

My home is near Newbury, where I live with my wife and three daughters.

Donna Judge - GDC Registration No: 83476

I qualified from the University of Birmingham Dental School in 2004. After completing a year in vocational training in Worcestershire, I have spent my time working in private practice both in Malvern and Rugby, before joining Triangle Dental in 2013.

I wanted to be a dentist for as long as I can remember and feel very lucky to be a member of the profession. I enjoy all aspects of dentistry, but am particularly interested in cosmetic dentistry. It is extremely important to me that patients have a treatment experience that is as pleasant as possible. I particularly enjoy putting people at ease, which can help nervous patients to undergo the treatment they need.

Triangle's philosophy of 'Maximum Prevention, Minimal Intervention' is something that I strongly advocate and I feel immensely proud to be part of such a forward-thinking team. Minimal intervention dentistry is a modern approach to treatment. It aims to control the cause of dental decay, restoring only where necessary, and prevent future tooth decay; preserving as much of your natural tooth substance as possible. I have been following this approach since qualifying from dental school.

Continuing professional development is a very important part of keeping up to date with the latest thinking and developments in dentistry. I have undertaken many courses to ensure I keep abreast of current techniques, including a two-year course in Restorative and Aesthetic Dentistry in Manchester, taught by one of the leading dentists in the UK. I am a member of Gloucestershire Independent Dentists - a group that meets several times a year for lectures from renowned world speakers.
