dr. aiyk is an excelllent endodontist...known as the best in Dallas. he has done root canals on both my sons over the years and they had zero complaints and actually enjoyed the experience if that can be possible. there have been zero issues with their root canal. he is really sweet and kind. dr. Berland recommends him and you can't get a better recommendation than the top dentist in Dallas. this review won't let me use capital letters.
