Dr Eoin O’Neill is an exceptionally skilled and very experienced dentist with a long-standing reputation for providing the highest standards of care to his patients.

It is Eoin’s belief that in order to deliver the highest level of care, a dentist should make every possible investment in the practice of his/her art – both through research and ongoing training, as well as through a continuous investment in any new technology or material that improves the patient dental experience – especially in relation to eliminating pain.

The end result of this approach is that every patient coming to O’Neill Dental Care can be assured that they are going to get treatment that is appropriate, highly effective, long-lasting, state of the art and as pain free as the latest technology allows.



Dr. Eoin O’Neill

Eoin graduated from Trinity College Dublin in 1998, and at graduation was awarded the IDA Prize for 1998’s Best Overall Student, as well as the Irish Dental Council Prizes for both Restorative Dentistry and Periodontology. After a period with the Dublin Dental Hospital teaching team, Eoin set up his own clinic in Swords in 2002, and built a forward thinking, friendly and vibrant family practice on the foundations of his exceptional skill as a dentist.

Always keen to explore new ways to improve treatment outcomes for his patients, Eoin continuously invests in training and new technology, and is one of those lucky individuals who finds himself at work every day doing something for which he has enormous passion and energy.

Eoin is a member of the AACD, BACD, ESCD, the IDA and is registered with the Irish Dental Council.
