If you think coffee only affects your cardiovascular system, think again. Studies have found out that black looking drinks like coffee and some soft drinks are responsible for most teeth discoloration. This is because our teeth gradually absorb the natural color of the liquid that we drink. If you constantly drink those stuff, you'd eventually develop ugly blemishes in your teeth.The first treatment on how to whiten teeth naturally is to simply brush them up and take time floss. Cavities are a known cause of discoloration also. By brushing your teeth on a regular basis, you are, in essence, getting rid of unhealthy stuff that gets stuck in the ridges of your tongue and in between your teeth.Brushing isn't enough, apparently. Buy floss, they cost real cheap. Flossing every night is a great way on how to make your teeth whiter and go to bed without lingering leftover food in the between that can otherwise lead to dark shades in the morning.When purchasing toothpaste, grab the one that has whitening ingredients. This is different from a complete whitening package. Toothpaste with whitening material only does half of the job, but they do it equally well. It has a stamp of American Dental Association in it to ensure that you're buying the best kind. They are proven to be effective clinical trials. The last thing you want is to purchase something that can be abrasive your teeth because they haven't gone through detailed inspection.Head out to your dentist's office for regular cleanings. Although flossing can remove a greater percentage of ugly stuff, dental will cleaning will sweep out the rest. There may be nicotine stains lodging a little under the gums which can't be reached by toothbrush and floss. And this is exactly what dental cleaning is all about.
