What is the best teeth whitening powder?
Some people no matter how many times they brush their teeth have teeth stains from habits like drinking coffee or tea and/or smoking. Oftentimes yellow- or brown-tinted teeth can also point to a larger problem: unhealthy gums, thinning enamel and overall poor dental hygiene. Whitening the teeth alone won’t help protect the teeth or gums from cavities or diseases, such as gingivitis so while white teeth are certainly a nice thing to have, it helps to keep things in perspective.
