Teeth Whitening for under $25! I get a LOT of questions about my smile. I have never had braces and never had my teeth professionally whitened. Yes, some of it may be genetic- but I have a CHEAP strategy- that absolutely got me THREE SHADES WHITER. I use the super cheap whitening strips from WalMart. Just finish the WHOLE pack- one time. Then every 6 months or so- do one strip. Done and done. LTKBeauty LTKFindsUnder50 LTKOver40
