I need a way to whiten my teeth quickly. I've used white strips before, but I didn't really like them as they didn't work well. I've also used whitening toothpaste, but those usually take over 2 weeks to work. What is a way that I can whiten my teeth quickly? By quickly I mean within two days. Also, I don't want to do anything that might damage my teeth.
Note: My teeth aren't extremely yellow, but they are definitely not white
