Do porcelain veneers lose their shine that quickly?

A couple of days ago I posted a question from Aaron in Indiana. He had a smile makeover that he said had lost its shine. I invited him to give me more information, because ordinarily porcelain veneers will not lose their shine unless they are abused by a dental hygienist with a Prophy Jet power polisher, or a fluoride treatment with acidulated fluoride. Both of these will remove the glaze on porcelain veneers.

He responded by describing his treatment to me, and enclosed a photograph of the work the way it looks now. Yes, it was porcelain crowns and porcelain veneers. And he confessed to having obsessive-compulsive tendencies.

Here is the photo:

 

Yes, I would say obsessive-compulsive here. These teeth still have their shine. The glaze is still there and they look fine.

Here’s what I told him:

 

To me it looks like a normal luster on the porcelain – the glaze is still there. There may be some polishing that could be done, but myself, I wouldn’t touch it. Nothing on porcelain is as good as the natural glaze. Porcelain polishes, because porcelain is so hard, have to be a diamond paste, and a polished porcelain surface to me is second best to the original glaze.

See Aaron’s reply. His dentist polished the veneers some, and he tried Supersmile toothpaste and loves it.
