I do not recommend teeth whitening. The cost of PLN 1,500. The whitening was performed in 3 cycles of 10 minutes each. Teeth before and after whitening in exactly the same color (I took pictures of myself). When asked before the procedure, the dentist said that there would be a spectacular effect next to my teeth. Let me have a slightly vanilla white before the treatment. They were of the same color immediately after the procedure. At my suggestion that nothing can be seen, the dentist informed that now for 2 weeks it would all work and they would whiten. For 2 weeks, as recommended, I followed a completely white diet. Teeth color has not changed anything teeth have not whitened anything. Totally thrown money down the drain.
