3 dangerous whitening hacks to stop

22nd August 2023

There are always new “whitening hacks” that pop up on social media, but unfortunately majority of these hacks are complete fads, as they don’t contain the correct ingredients to whiten teeth and could harm your oral health.

1. Lemon juice

A popular fad that circles the internet. Although lemons are rich in citric acid, which is a natural bleaching agent used on hair and fabric, applying something that’s extremely acidic on your teeth for prolonged period will wear down the enamel that protects your teeth. This damage to your enamel is irreversible and can lead to sensitivity and decay.

2. Turmeric

Turmeric and teeth whitening should never be mentioned in the same sentence. Although this natural ingredient can do wonders for your health, when it comes to teeth it’s best to put the spice down.

While it can help to remove plaque, bacteria, and reduce inflammation, it causes yellow/orange staining on your teeth and gums, instead of making them whiter. Since the spice is used to dye fabric, it’s no shock that it can significantly stain teeth. Avoid.

3. Purple shampoo

This TikTok viral hack shows people using purple shampoo, which is usually used to tone dyed blonde hair, as a whitening toothpaste. The idea is that the purple hue will cancel the yellow tones on teeth, creating an instant white smile. However, shampoo shouldn’t be anywhere near your teeth. Not only does it not have the correct ingredients to whiten teeth, ingesting it can have serious implications for your health.


The best way to a white smile is through safe, effective professional teeth whitening treatment with your dentist. Just as with all health advice, avoid taking dental advice online and from anyone on social media that isn’t qualified to provide it.
