Teeth Whitening: Does It Work?

Teeth WhiteningPerfectly-aligned teeth with or without dental braces and other orthodontic devices are no match to white teeth that boost one’s confidence. Every single magazine cover and billboard projects the image of a model with a set of white teeth. But do whitening products really work or is it all just a result of a photo editing software?

Understanding the Teeth

Before you begin to appreciate how teeth whitening products work, understand something about the teeth first. A single tooth is composed of two layers, an inner dentin layer and an outer enamel layer. The enamel is the one that protects your teeth from all the things that you put inside your mouth.

So Why the Discolouration?

Discolouration occurs because of staining agents that permeate through the enamel layer. The years of eating, drinking and smoking create a pellicle film on top of the enamel. The chemicals present in the pellicle layer eat their way into the enamel. Some of these chemicals are powerful staining agents. You see your teeth gradually changing in colour as the years go by.

How Do Teeth Whitening Products Work?

In order to be effective, teeth whitening products must pass through the pellicle layer and into the enamel, where its bleaching properties work on the various staining agents present inside the enamel. The bleaching agents oxidise the chemicals that stain the teeth, breaking their bonds apart. The result is the loss of their staining properties, leading to a more natural-looking off-white enamel colour.

You do not need a bleaching type of teeth whitener if the stain has not penetrated deep into the enamel. Smylife says visiting a cosmetic dentist in Manchester to scrub off the superficial stain is often enough, especially when used in conjunction with brushing using toothpastes that have mild to moderate abrasive properties.

No matter how you look at it, a set of white teeth may boost your confidence and make you want to smile more often. This greatly increases your likability, a must in today’s competitive environments.
