This is a scam! I went in for a cleaning, xray and exam and after receiving analogue x-rays from an old rusty machine, (everyone goes digital now) I was told that I had 5 cavities and needed $900 worth of treatment. I've never had a cavity in my life. After seeking a second opinion, I found that I have no cavities and the "spots" on my teeth were a bit of stained sealant that was protecting my teeth. I would have 5 unnecessary holes in my teeth had I listened to Dr Charles A. Arias. Don't do it!
