We are now 11 days out from the wedding and after brushing my teeth today I realized I forgot to start whitening and that I could use it.
I have crest professional supreme white strips at home and it says it will take 21 days to finish the kit. Is it worth doing still? I'm just wondering if it will whiten them unevenly and I'll be worse off or if it will be even just not as white as if I had started with 21 days to go.
Thanks for any tips and comments in advance
