I tried teeth whitening at home using strips and my teeth did not get whiter. In fact they were sore and gums were red. It was painful. The reason for this is that I did not know that my gums were infected and that the trays were not made to custom fit my mouth.
The at-home-whitening treatment for application during the day which i have used at Eternal Smiles made my teeth so much more whiter. 7 shades whiter in 2 weeks. The whitening system at Eternal Smiles did as they had promised. It was a spectacular result. My friends have had it done with them and it beautiful results. It was a comfortable process.
