I warmly recommend Dr Łukasz Lassmann, he is the right person in the right place. The doctor is very nice and supportive in difficult moments, he encourages you when things seem impossible to be done (like treating a wisdom tooth or draining pus pockets). Highly committed to his work, he enjoys the effects of his work together with the patient, as if he treated his own teeth :) I have lived in the Tricity for a few years and Doctor Lassmann is perhaps the sixth dentist I have visited, but I will seek no more as I think I could not have found any better one!
