Teeth have both opaque and transparent characteristics. When light passes through an item, it scatters or diffuses rather than passing completely through, according to the definition of transparency. Diffusion is best understood by picturing the frosted glass frequently found in bathroom windows. There is enough light passing through to enable for the very faint visibility of an item. Enamel has transparent qualities, too.
Opacity denotes a complete obstruction to the passage of light. A wooden door would be one illustration of this. The door may allow light to enter through or around it, but not straight through. A tooth’s dentinal layer is an illustration of an opaque media.
Stains from smoking, alcohol, tea, and coffee frequently obstruct the “natural” white whiteness of teeth. This issue is addressed by whitening products designed for both home use (such as toothpaste and toothbrush combinations) and expert use in dental offices (such as bleaching or expert dental cleaning). Any technique to make teeth appear whiter is referred to in this sense as “whitening.”
Modern Oral Care
Modern oral care treatments are designed to prevent periodontitis and caries, two conditions that are widespread problems in human civilizations. A healthy diet (low sugar intake, no extensive use of eruptive drinks) and lifestyle (no smoking, low levels of stress, not even being overweight) are the major ways to avoid dental caries and periodontitis. You can also use an electric or manual toothbrush and toothpaste to brush your teeth.
Fluorides (sodium fluoride, amine fluoride, etc.), stannous, chlorhexidine, zinc salts, calcium phosphates (such as hydroxyapatite/amorphous calcium phosphates), surfactants, as well as various abrasives for effective plaque removal, are just a few of the numerous agents used in modern toothpaste formulations to prevent caries and periodontitis.
Additionally, a growing variety of dental care products also (and occasionally exclusively) concentrate on tooth whitening. This is because many people enjoy having white teeth as well as a bright smile, since these things may also enhance their life quality. Teeth might get darker due to lifestyle choices like smoking, drinking red wine, or drinking black tea. Additionally, the age of the teeth affects their overall colour.
As a result, numerous various teeth-whitening products have been released by oral care companies. Here, we provide a review of popular teeth-whitening products and talk about both their effectiveness and any potential drawbacks from the perspective of a chemist. We think this will make it easier for patients and dentists to weigh the advantages and potential hazards of teeth-whitening procedures. We also expect that after our thorough evaluation from a chemical perspective, several myths that are utilised to sell particular compositions will be more severely examined.
