Q. I have bonding, approx. 12 years old, on my two front teeth which are stained yellow. I am going to do an at-home whitening system. Do I need to wait 2 weeks after I’ve totally completed the whitening before I have the bonding replaced ? Thus, do I need to wait in order for my teeth to fully absorb & change color to the final “whiteness” in order to accurately match the bonding to the new white? Also, I’ve been told that I cannot do the ZOOM in office whitening because I have extremely sensitive teeth. Is this true as well?
