Purple teeth whitening stuff

[onlyconnect]

I've seen this all over Instagram. Has anyone tried it? Does it work?

It doesn't whiten them, it works in the same way a toner on hair does, it neutralises yellow tones. It won't remove stains etc.

Home Bargains currently have a purple toner in for teeth for shout 2.99 and it's way better than that stuff you see peddled on IG at over £10 a bottle.

I use it every other day, because I have poor enamel so yellow shows up super quick. It doesn't whiten them, it just...keeps them the colour they should be.
