What Causes Surface Stains on Our Teeth?
There are many reasons why our teeth start to yellow. Some of them are things we simply can’t control, such as age or accidents that may disturb our tooth enamel’s development.
Medications and diseases can also affect the enamel (a.k.a. the hard surface of the teeth) and dentin (the material under the enamel), leading to discolouration.
However, there’s also plenty that we can control. Keep reading to discover some of the most common causes of tooth discolouration.
Food and Drinks

Unfortunately, what goes into our mouths has a likelihood of staining our teeth.
Food and drinks like coffee, tea, soft drinks, wines, and even certain fruits and veggies like apples and potatoes can stain your teeth. Some starchy foods like pasta can also create conditions that lead to staining.
Smoking

Smoking exposes your teeth to both tobacco and nicotine, which doesn’t only cause yellow teeth, but also give you bad breath.
Poor Dental Hygiene

This should go without saying, but if you don’t brush and floss your teeth regularly, you’re creating the perfect environment for plaque and stain-producing substances to call home. This is why practising proper daily dental hygiene is so important.
How Do Whitening Toothpastes Work?

Whitening toothpaste generally works by using enamel-safe abrasives to buff away surface stains. It targets the enamel and often uses a combination of methods to maximise its whitening effects.
Optical
One of the few methods used in whitening toothpastes, the optical approach uses blue-toned brighteners that coat your teeth as you brush. This blue pigment is what gives you that instant whiteness and provides an immediate result.
Buffers
Also known as abrasives or polishers, the buffing method works by using tiny scrubbing agents, such as silica or activated charcoal, to remove stains and plaque from the teeth.
A word of caution: prolonged use may wear down your tooth enamel, which can lead to sensitivity down the road, so you may want to reach for whitening toothpastes with these agents a little less often.
Enzymes
This particular method employs the help of enzymes derived from fruit to gently break down and dissolve proteins on the teeth that are linked to staining.
Chemical
Whitening toothpastes may sometimes use a chemical, such as hydrogen peroxide and carbamide peroxide. These agents help to bleach and lighten stains on the enamel for a brighter, whiter smile.
