Dr. Lum worked in conjunction with Dr. Brian Tang to do some implants on my front teeth. I had a bridge which fell off and couldn't be fixed. It took a few months to fix to process but now my teeth look even better than with the bridge! I wish I did the implants rather than the bridge from the get go! Dr Lum was excellent and explained everything and quarterbacked the whole process. I felt like in was in control of my treatment the entire time and was never pressured to do anything. Dr. Lum repeated so many times, I can quote him, "We'll do what you want, when you're ready." Great guy!
