I've been using opalescence 35% with no change (pic included)

I have used opalescence 35% a few times now and have not noticed anything apart from a few tiny white spots on my teeth, I am a smoker and do drink soda/tea/coffee.


But I am willing to quit all of that if I can have nice white teeth.

Looking for to your replies, kind regards.

 

You don't sat how you're applying the bleach. Is it in a tray made by a dentist or a DIY over the internet type? And there are some people's teeth that don't respond to bleaching.

 

Hi, I'm using a home made boil and bite tray, which my dentist said was fine but the gel is dangerousness and shouldn't be used.

I'm in the UK.
