I've tried the cheapy options and none worked. I am going to smile labs for a one hour session on a Monday because it's half price $125 and they have good reviews. I can let you know how I go but it isnt Until october

I use charcoal toothpaste. It doesn’t taste the best but it works for me. My hubby uses the white glo white accelerator blue light kit. It seems to be working too

I know you mentioned options not involving the dentist, however just thought I’d mention that my dentist offers a take home whitening option. Depending on your budget it may be worth talking to your dentist to see if they offer something similar. It’s much cheaper than a traditional in-chair whitening procedure.

As I’m sure you’ve seen the supermarket offers lots of whitening toothpastes, but in my experience they don’t really do that much, but for a few dollars it doesn’t hurt to try.

Are you due for a clean? When they clean your teeth they will often remove staining which can make the teeth look better overall too.
