The Science 🔬
How does teeth whitening work?
Discolouration and staining are a direct result of various dyes and pigments, from the foods and drinks we consume daily, attaching to the organic matter of your tooth. The process of lifting these stains can be achieved by two methods: physical removal or chemical bleaching.
Physical removal targets superficial staining (surface level daily stains) through an abrasive method of action.
On the other hand, chemical whitening works to remove embedded stains (stains within the tooth enamel which cause discolouration).
How does chemical whitening work?
Chemical whitening oxidises stains and alters the molecules that are responsible for holding colour, in order to whiten them.
To put it simply, the whitening agents enter through the enamel of teeth and break down these molecules into smaller forms. The smaller the molecule, the lighter in colour it is, the end result is an overall whiter appearance of the tooth.
Our Teeth Whitening Strips contain the whitening agent Phthalimidoperoxycaproic Acid (PAP, for short) in order to chemically whiten the teeth by removing the intrinsic stains found within the enamel.
How does physical removal whiten teeth?
Whilst chemical whitening can whiten the teeth through the removal of intrinsic stains (staining below the surface of the tooth). Teeth can also be whitened by physical removal of extrinsic stains (staining on the surface of the tooth).
An extrinsic tooth stain is staining on the surface of the tooth. It occurs when stain particles, such as pigmented residue from food or drink, build-up in the film of protein that covers the tooth enamel. Extrinsic tooth stains are typically caused by tobacco use or by regularly drinking coffee and tea, wine or fizzy drinks. This type of tooth stain responds well to regular dental cleaning and brushing the teeth with a powder.
Our Teeth Whitening Powder does just that. It removes extrinsic stains, in order to whiten and brighten the tooth's surface.
Remove extrinsic or intrinsic stains?
With the above explained you may be wondering which stains are the most important to remove, in order to whiten the teeth.
Simply put, they're both as important as each other when it comes to the colour of your teeth, and therefore removal of both extrinsic and intrinsic stains is the fastest way to whiten and brighten the teeth.
