1. Whiten those teeth. Try an at-home whitening product like Crest 3D White Whitestrips, $49.99 to get rid of all those coffee and soda stains (busted).



2. Get rid of flaky lips. Gently exfoliate with a wet old toothbrush to get rid of dry lips, then follow up with a super-moisturizing lip balm like Jurlique Love Balm, $15 or Avene Cold Cream Lip Cream, $14.



3. Wear a fun lip color. We’re digging CoverGirl Lip Perfection Lipsticks, $6 in Siren (a bright pink) and Everlasting (a deep red). Either color is perfect for a notice-me mouth.



4. Smile. Yep, it’s super-obvious, but smiling draws attention to that gorgeous mouth you’ve got, and just makes you seem like an all-around awesome person. So keep the grins coming.
