Will getting Bioclear for black triangles make teeth more prone to cavities and other damage or decay?

I have some black triangles on my bottom front teeth that I went in for a Bioclear consultation on. Since the entire tooth will be covered in composite resin afterward, will this cause the underlying tooth to be more prone to cavities or any other damage/decay since now you won't be able to directly brush that tooth anymore due to the composite covering it?
