Let’s face it, we all want the whitest teeth possible. But have you been trying the hardest to get those desired results that aren’t apparent yet? We have a few reasons as to why your teeth may be going from dazzling to dull white using whitening toothpastes.
First, it is important to note that whitening toothpastes can’t change the actual color of your teeth. They also don’t contain peroxide which is a key ingredient for teeth-whitening. Most ingredients included in whitening toothpastes only remove surface stains, which means that it can’t lighten a stain that is deeper than surface level.
Second, the overuse of whitening toothpaste can wear down tooth enamel, which, in turn, can cause a yellowish shade on your teeth. Although it takes about two to six weeks to see results when used twice a day, it is well worth the wait instead of using the toothpaste more than you should just to have your teeth become less white than they should be.
So although whitening toothpaste may deliver some results overtime, it may not thoroughly do the job as much as teeth whitening treatments provided by your dentist.
