Important information you need to know about teeth whitening toothpastes Teeth staining and sensitivity are two of the most common issues present today. However, they are equally easily overlooked by a majority of people. While there are in-office treatments, over the counter medications, and other methods available to deal with these issues, the most convenient way is brushing. Although brushing might not give you instant results, it helps in putting up a consistent fight. Considering how neither sensitivity nor teeth staining can be cured once and for all, affordable teeth-whitening toothpaste for sensitive teeth is your best bet. Research has suggested that regular brushing with such specifically designed toothpastes helps remove surface stains caused by the foods we eat. This, however, does not help with the natural color of your teeth or the discoloration present beneath the surface. What you should know about teeth whitening toothpastes Whitening toothpastes can be abrasive, and they work by polishing the stains off. Some other types contain chemicals like peroxides that break down the stains. If you are worried that these might harm your teeth, you can opt for products that have items like charcoal or activated carbon and zinc citrate in them. Some other whitening toothpastes contain blue covarine.
