Nature's Gate Toothpaste - Whitening Gel (141g)
I bought this on sale and I was really happy with the results, they we're actually better than expected. It cleans really well and keeps my breath fresh all day. One tube lasted about a month using twice daily so I feel like the results were definitely worth the price.
I never realised how sugary big name brand toothpastes are until I ran out of this!
