Do tooth whitening toothpastes really work?
|Teeth whitening toothpastes seem to be popping up everywhere and you've got to wonder if they really work.
Whitening toothpastes, like all other toothpastes, contain mild abrasives to remove surface stains. Teeth whitening toothpastes may have additional polishing agents and special chemicals that are more effective against stains than regular toothpastes. While whitening toothpastes can make your teeth appear a little lighter, by getting rid of stains, they do not actually bleach your teeth.
Teeth whitening toothpastes are ideal for people who smoke, drink coffee and tea and eat certain foods that can stain your teeth. Teeth whitening toothpastes are also good to use after you have undergone a teeth whitening procedure to keep surface stains from building up on your teeth.

|How Often Should I Change My Toothbrush?|
|Adults and children should change their toothbrush every 3 months because they become worn out and are not as effective as they once were. Exceptions to this would be if you were using an electric toothbrush, and the manufacturer states otherwise. Some electric rechargable toothbrushes have very good brush heads that only need to be changed every 6 months. If you have gum disease, you should change your toothbrush every 4 - 6 weeks because bacteria can harbor in the bristles. You should always rinse your toothbrush out with hot water after every use and change it after you have been sick.
