I have okay colored teeth

They've been getting more yellow/stained recently because I've been drinking black coffee And green tea

Tonight I'm Going to buy:

New spinning toothbrush(I read these are way better)
New floss
Whitening toothpaste
Whitening mouth rinse
Crest White strips

Not sure which ones I should get, they range from $20 to the deluxe $60 which is tempting but it might be a scam smh.

For real though, baking soda will do a lot of work.
