Dental TikTok trends have become increasingly popular over the past year, with users sharing tips, tricks, and hacks for achieving a perfect smile. While some of these trends can be harmless and even helpful, others can be downright dangerous and cause long-term damage to your teeth and gums. In this article, we’ll explore some of the most popular dental TikTok trends and why they are dangerous.

Using baking soda to whiten your teeth

One of the most common dental TikTok trends is using baking soda to whiten your teeth. While baking soda can remove surface stains, it can also erode your tooth enamel over time. This can make your teeth more susceptible to cavities and tooth decay. In addition, using baking soda too frequently can cause tooth sensitivity and gum irritation.

DIY braces

Another dangerous dental TikTok trend is DIY braces. Some users suggest using rubber bands or other materials to move your teeth into alignment. However, attempting to straighten your teeth at home can lead to serious problems, such as tooth loss, infection, and even jaw damage. Orthodontic treatment should always be performed by a licensed professional.

Using activated charcoal

Activated charcoal is another popular dental TikTok trend that can be dangerous. While it can remove surface stains, it can also absorb important minerals in your mouth and digestive system. This can lead to enamel erosion and tooth decay. In addition, charcoal can be abrasive and cause damage to your tooth enamel and gums.

Oil pulling

Oil pulling is a dental TikTok trend that involves swishing oil in your mouth for several minutes to remove bacteria and toxins. While oil pulling can be a useful addition to your oral hygiene routine, it should never replace brushing and flossing. In addition, some oils, such as coconut oil, can cause allergic reactions and skin irritation.

Using lemons to whiten your teeth

Finally, some dental TikTok users suggest using lemons to whiten your teeth. However, lemons are highly acidic and can erode your tooth enamel over time. This can lead to tooth sensitivity and decay.

In conclusion, while dental TikTok trends may seem like a fun way to improve your smile, they can actually be quite dangerous. It’s important to always consult with a licensed dental professional before attempting any at-home treatments or remedies. In addition, sticking to a consistent oral hygiene routine, including brushing and flossing regularly and visiting your dentist for regular check-ups, is the best way to maintain a healthy smile.
