When you hear about a healthy smile, what comes to mind? People often associate pink gums and white teeth with good dental health, but as you get older, your teeth might take on a yellowish or brownish cast for reasons beyond poor oral care. Your genes or your diet may be to blame, according to the American Academy of Cosmetic Dentistry (AACD).
If getting a brighter, whiter smile is on your to-do list, you have options, from at-home whitening treatments to those at your dentist's office. You might also think of trying a do-it-yourself teeth whitening paste. There are several homemade concoctions you can try, and they'll all compare differently with the results you'd get from a dentist or over-the-counter (OTC) product.
