To get your teeth their brightest and most white treating them with the Zoom system might be your best option. After evaluating several options we found the Zoom system to be the best.
The patient below is a good friend of the office and allowed us to whiten just his upper teeth to document the amount of color change. Notice the drastic improvement. Shortly after we whitened his lower teeth for a fully bright smile. (We normally whiten both uppers and lowers at the same time)
