The first step is to get the opinion of a professional who knows about these products and would be able to give you the right advice.

Your dentist is somebody who will give you an honest opinion about these products and since he knows about the condition of your teeth and their structure, he would be able to advise you accordingly.

What is for sure is that a visit to the cosmetic dentist is nothing to be particularly anxious about; as most procedures that take place there are not particularly painful or otherwise uncomfortable.
