Is Aluminum Foil Teeth Whitening Safe?

Is aluminum foil teeth whitening safe? We've all heard about this DIY method, but is it really effective and safe?

In essence, aluminum foil teeth whitening works by making a paste using baking soda and water, applying it to your teeth, and then wrapping your teeth in aluminum foil.

While this is indeed a creative way to whiten your teeth at home, it's not the safest whitening method. The combination of aluminum foil and baking soil in direct contact with your teeth and gums for any length of time can potentially damage your tooth enamel.

In our quest for a brighter smile, we'll delve into this topic, providing you with the most accurate and helpful information about aluminum foil teeth whitening and offering you whitening alternatives by SNOW.

How to Whiten Teeth with Aluminum Foil

The aluminum foil teeth whitening method involves wrapping your teeth with aluminum foil after applying a paste made of baking soda and salt. 

Does Aluminum Foil Teeth Whitening Really Work?

The idea is that the foil helps speed up the whitening process. The key to safe teeth whitening lies in the ingredients that whiten teeth and technology, like how we use blue LED lights in our teeth whitening toothbrush to enhance the whitening process even more while cleaning your teeth.

While baking soda can help remove surface stains in this instance, aluminum foil and baking soda aren't a long-term solution for deep-set stains.

Is it Safe To Put Aluminum Foil In Your Mouth?

After conducting experiments with it, we found that putting aluminum foil in your mouth isn't the most effective or safest whitening method out there.

The aluminum foil method doesn't involve any protective measures against gum irritation or tooth sensitivity and can cause enamel erosion, which are common issues with untested DIY teeth whitening methods.

For a safer alternative, we recommend trying our whitening strips. We determined through our tests that they're made with the best teeth whitening gel for sensitive teeth, removing years of stubborn tooth stains without damaging tooth enamel.

The Recommended Age To Perform Teeth Whitening With Aluminum Foil

Based on our observations, the recommended age for teeth whitening using aluminum foil is for people aged 16 and above; in other words, older teenagers and young adults can use this whitening method without significantly damaging their teeth.

While the method involves using baking soda, which isn't a typically harmful whitening ingredient, it's important to note that children younger than 16 shouldn't use aluminum foil for teeth whitening.

This is because they have weaker tooth enamel that's still developing and the potential risk of over bleaching teeth. The same goes for the elderly, who also tend to have more delicate enamel.

A better alternative to using baking soda as a whitening toothpaste is to get the real thing instead - our top whitening toothpaste. Teenagers 16 years old and older, as well as senior citizens, can use it on a daily basis and leave it on their teeth for more than a minute before rinsing with our alcohol-free whitening mouthwash to ensure longer-lasting cleaning and whitening results.
