Three years ago I used crest 3d whitestrips on my upper teeth to see if it actually worked. And it did. My upper teeth went from stained yellow to clear white in appearance. I then did a 2 year update video to see if the teeth reverted back to its original appearance.
Now is the third year update and possibly final video of this series. I have not used whitestrips at all since applying it 3 years ago. So do the results stand the test of time.
Original video: • Guy with yellow teeth ...
Year 2: • Teeth Whitening Strips...
Year 1: • Teeth Whitening Strips...
