My brother in law is a dentist and he gave me Colgate Overnight prescription whitening gel. You use it with a tray in your mouth overnight.
Well I gagged on it all night and it made me nauseous, and it didn't whiten all that much.
Then I tried Colgate Simply White Night which you brush on your teeth. Seemed to rub off as soon as I closed my mouth, and I couldn't see any improvement at all
Finally tried Crest White strips and was surprised. They worked great and no nausea or sensitivity for me. Now all the women love me...
