In the last 5 years, everything in my mouth has been replaced with all new porcelain materials. Stephen Rose is very picky about the work that leaves his office and when something wasn't manufactured correctly, he made the manufacture replace it! Dr Rose has the most modern equipment of any dentist I have ever met and it seems like he has a new treatment device each time I see him. As a result, even though I am nearly a senior citizen, I have a beautiful smile!
