Okay I have tried tons of toothpastes!!! I want to find one that whitens but actually cleans the teeth. That's safe and has the dentist approval thingy. I also want it to make my breath smell better. All the ones I tried made it smell terrible! I also need to know your opinion on whitening strips? Which give best results? Do you think that they don't work? Is it better to get a dentist to do it? Please help me!!!!
