How to choose the best whitening toothpaste?
Does toothpaste include Short-term whitening or long-lasting polishing against stains?
Whitening toothpaste contains active oxygen, carbon, and zinc peroxide in makeup. They have an immediate effect by lightly coloring the gums, tongue, or enamel with a red or blue tint, which gives the impression that you have whiter teeth. But only overnight. For a real whitening effect that lasts over the long term, use polishing agents such as silica, perlite, or sodium bicarbonate instead. These are effective after 15 days of daily use. By lightly abrading the enamel, they reduce and remove stains from coffee or tobacco.
Does toothpaste include Antiseptic agents that limit the formation of tartar?
Triclosan and chlorhexidine are two anti-bacterial that inhibit the formation of tartar and plaque. With their anti-inflammatory properties, they protect the gums and limit odors. However, due to its impact on hormone regulation, whitening toothpaste containing triclosan will not be recommended for pregnant women and children.
Does toothpaste include remineralizing agents to prevent cavities?
Fluoride is sometimes criticized because of the risks caused by its overdose (white or brown spots on the teeth, bone weakness). However, at low doses, potassium and sodium fluorides are very effective in preventing the formation of cavities since they remineralize and protect the enamel from acid attacks.
It is advisable to avoid aggressive detergents but to favor fluorides.
Most whitening toothpaste contains abrasive polishing agents, which can weaken tooth enamel. It is therefore advisable for people with hypersensitivity to use products enriched with stannous fluoride and potassium nitrate. These allow a significant reduction in tooth sensitivity. As for people prone to periodontitis and gingivitis, sodium lauryl sulfate is not recommended. Frequently used as an anti-bacterial detergent to remove plaque, it is also known to irritate the gums and promote canker sores.
