Personal Whiteners, Daily Or Not
There are many types of toothpaste, and the truth is something difficult when we want to buy one. Since they all promise teeth whitening, but the prices are very different and the components too, then which one is the most appropriate?
These whitening toothpastes are the most economical, they whiten thanks to the small particles they contain, they are generally silica, calcium carbonate or dicalcium phosphate.
These toothpastes are usually the most economical and are especially effective when there are spots. Since these act “scratching”
Although it is necessary to watch since they are very abrasive, they can damage or break the enamel. The abrasion capacity of these pastes is measured by the RDA (Relative Dentin Abrasivity, in USA) the maximum authorized levels are 200.
For sensitive teeth it is important that these levels are low. If the paste also has some fluorinated salt, it will help protect the enamel.
These toothpastes usually contain as a bleaching agent the carbamide peroxide, the hydrogen peroxide or the sodium tripolyphosphate. The strength of these pastes depends on the concentration of these substances in them.
Many are combined with the abrasive bleaches to improve the effectiveness, since the abrasive particles, remove stains and chemical components, whiten the tone of the enamel.
These agents whiten by diluting the components that stain the teeth. Some pastas in turn also contain a substance that leaves a blue trace on the teeth which visually gives the feeling of whiter.
Hydrogen peroxide irritates the gums, so it is quite rare in whitening toothpastes. Carbamide peroxide is more common, although at very low doses.
The methods with splints, use this product in gel form and at approximate doses of 30%.
These toothpastes use the fruit enzymes of papaya, pineapple, and other proteolytic enzymes, such as papain and bromelain.
They act by dissolving tooth stains more naturally. And more bioavailable.
These components are often combined with the previous ones.
These pastas are the most expensive, although they are the least aggressive with teeth and effective whitening.
Strips or whitening strips
These products are very fashionable especially in the USA, they are flexible strips that contain peroxides.
They are quite effective, since they usually have high concentrations of peroxides, 5 minutes a day is enough.
