 I am a current customer of Southgate Dental. I am very happy with Southgate Dental. The office and surgery are sparkling clean and modern, the reception staff are at the top of their field, friendly and very helpful. As a nervous patient the entire staff helped put my mind at ease. The dentist himself was very informative and gave me mutipul choices on treatments which i did not get elsewhere. The work so far is of excellent quality and i would have no problem recommending Southgate Dental to any of my friends or family. To top off all the good that is Southgate Dental the one thing that first attracted me to their office was the price. I am paying upto 40% less than i was quoted in Dublin.
