There seems to be a number of popular natural remedies for whitening teeth, but you’ll find arguments on both sides for virtually all of them. The one option that seems to be acceptable to most “experts” in the field is the use of baking soda. Some recipes call for an addition of salt to the baking soda, and many recommend that you brush your teeth with regular toothpaste after using the baking soda cure. This option will show some results, but keep in mind that baking soda is an abrasive and over time can damage the enamel of your teeth.
Another popular option is using a strawberry, which can be mashed up and used on the teeth as a form of paste, or applied with a toothbrush. This is one of the natural teeth whitening options that can be effective but can also be dangerous if used often. One of the active ingredients in the process is the acid the berry contains, and another is the tiny seeds that can damage both tooth and gums if they are brushed into the surface. One dental expert says that it’s an effective option but don’t do it often.
The lemon peel treatment is almost as well known as the baking soda option, but much more dangerous. The suggested treatment is rubbing your teeth with a lemon peel and then brushing. Lemons are loaded with citric acid, which will damage the enamel of your teeth fairly quickly if it is brushed on. This option is probably one to stay away from.
Hardwood ash contains potassium peroxide, otherwise known as lye. Some natural remedy sources suggest using hardwood ash as a form of toothpaste in order to clean and brighten the teeth. The potassium hydroxide is a bleaching agent and will whiten your teeth, but will also harm them if used on a regular basis over a period of time. It’s also got to taste terrible. It is however a form of natural teeth whitening if not overdone.
