The answer is you will get good results if the treatment process is correct and the doctor understands your tooth structure!

From the knowledge of dentistry and understanding of the tooth structure, the doctor will specify the appropriate and safe bleaching concentration, adjust the whitening light for optimal results, as well as the appropriate whitening time!

I don't know what your opinion is, but to me, "Dosage and use always have an influence on the effect of the drug and the treatment results, even if it is only very little!"
