For white teeth, there's truly no other product that matches Crest 3D White Professional Effects Whitestrips ($28, originally $50) — customers rave about them; just read the 45,000 reviews on Amazon. The results can last 12 months and beyond; all you have to do is use them once a day for 30 minutes.
White strips can remove 14 years of teeth stains for a whiter smile. Plus, they're pretty comfortable to wear — the brand's Advanced Seal Technology means there's a no slip grip that stays put, so you can talk and drink water while whitening teeth. OK, we might buy a couple boxes.
