I was visiting Las Vegas and my porcelain crown came off. It was a Friday afternoon and I called to see if I could get in. They took me in, x-rayed my tooth and put the crown back on and used the x-ray to check the fit. It was perfect. When I went to check out, they told me there would be no charge. They could have taken advantage of my situation but they didn't. Very nice people and very clean office.
