What are some of the best teeth whitening toothpastes? Why?
Are there any other ingredients I should look for when choosing a teeth whitening toothpaste?
Yes, another ingredient to look for is fluoride, as it can help prevent cavities and build up of plaque. Additionally, some toothpastes contain charcoal which helps to absorb stains and bacteria from the teeth and gums.
