When I see celebrities on TV, their teeth are really pure white;;
Is it because it's laminate?
Anyway, I'm somewhat interested in teeth whitening.
I understand that whitening treatment is done using teeth whitening products.
I'm curious about how long the whitening effect lasts after an initial satisfactory whitening treatment.
Of course, since everyone's eating habits and lifestyle habits are different, there may be some slight differences.
I'm curious about how well maintenance is sustained with this level of investment.
And are there absolutely no concerns about side effects with teeth whitening???
