Dr. Peter Dwyer

Principal Dentist BA, B.Dent.Sc., Certificate in Orthodontics

I am a general dental surgeon and have 26 years’ experience running clinics in Westmeath, London and Dublin. I initially gained my qualifications in dentistry at Dublin’s Trinity College in 1987. For the past 8 years I have provided general, emergency and cosmetic dentistry at Frederick Dental Clinic.

Both adults and children have praised me for my relaxed and informal approach to dentistry and I enjoy helping nervous patients overcome their fears. Before your treatment begins I will ensure you know all the details about what will happen at each stage of the procedure. I will also answer all of your questions and make sure you feel relaxed and free of dental anxiety before treatment starts.

I am a general dentist who provides all aspects of restorative dentistry and having gained a certificate in orthodontics from Warwick university I now provide adult and child orthodontics (see own excellent before and after results).
