Whitening toothpastes are able to produce long-lasting results because they combine polishing abrasives with stain-removing ingredients. Two of the most common abrasives in whitening toothpastes are Hydrated aluminum oxide, Calcium carbonate, and Magnesium carbonate
Some of these toothpastes may also contain hydrogen peroxide or carbamide peroxide, both of which are effective teeth whiteners. Despite the speedier results of carbamide peroxide, the two-week time frame and the other ingredients all produce the same amount of change in color.
Relevant Product Factors
You should choose a whitening toothpaste that won’t cause any harm to your teeth and gums. In this case, the American Dental Association (ADA) seal of acceptance is what you should be looking for.
Items that have earned this certification have been tested extensively and proven safe and effective. Although earning an ADA Seal is entirely voluntary, it is a great way to show that your product was made to the highest standards of quality and reliability.
No bleaching or whitening product is risk-free, but those bearing the ADA Seal of Acceptance have been shown to be safer than others. Whitening toothpastes and related products most frequently cause moderate gum and mouth irritation. The sensitivity of your teeth may also rise.
Whitening toothpastes get their effectiveness from abrasives, which can efficiently scrub away surface stains but can also damage some of the tooth enamel in the process. When the enamel on your teeth peels away, the discolored dentin underneath becomes more visible.
For 39% of participants in the manufacturer’s clinical trial, Arm & Hammer Advanced Whitening significantly improved tooth brightness. While 75% saw an improvement, 25% were left with darkened teeth, highlighting the possible dangers of using such treatments.
