Transcript for TikTok users turn to app for DIY dental care
We turn to the unexpected source many people are going to for denialadvice, tiktok. There are apparently hugely popular video, some with millions of hits that show a DIY approach to treating your teeth posted by people who and we should say this repeatedly and clearly are not dentists. Will reeve is back with more on shrinky new trend. Hey, will. Reporter: Hey, Dan. I have a confession to make I have not been to the dentist in a while. I'm sorry but I've also not yet been to tiktok in place of my dentist. Many people have, though, and the dental advice on there is out experts say beware. Wow. You can really dance. Reporter: This morning tiktokers aren't just singing an dancing, some are searching for DIY dental care. The pandemic has turned the popular social media platform into a surprising P for oral hygiene advice. Despite studies showing a visit to the dentist is relatively low risk for transmission of the covid virus, many are looking to stay home and save money so some users, mostly teenagers are offering tips and tricks, posting how to videos they say will show you how to improve your smile at home. And we're doing it on a budget. Reporter: This has nearly 500,000 views and shows a young woman filing down her front teeth to even out her smile. Other users doing the same and showing off results online but dentists warn these quick fixes can cause big problems. We happen to call this procedure enamelplasty. They shouldn't be doing it at home. There are three layers of the teeth. There's the enamel, the dentin and the pulp which is where the nerve is so once you remove the enamel you're in the dentin and that's very sensitive. Reporter: If you have thin enamel to begin with Dr. Rosen says amateur filing could leave you cracked tooth. For those looking to whiten their teeth, some tiktokers brushing with baking soda. It's salty and gross. Reporter: Or even trying bananas. Place it on your teeth for ten minute. It is proven that baking soda because it's an abrasive will remove some surface stains. Now, if you use plain baking soda all the time, that is way too abrasive and these things can actually make the tooth more porous. Reporter: As for the banana, there's no scientific research to say it works or to evaluate its safety. Another trick being touted on tiktok for whitening, hydrogen peroxide, the chemical compound used as an antiseptic. I put a little on my toothbrush and brush like normal. Reporter: While experts say it may whiten teeth unless you're using a product intended for dental care be sure to dilute it. If done at a high concentration it will make the enamel sensitive because it could erode it. Reporter: Experts say it is always better to consult with a dentistry professional and some can be found on tiktok but make sure that you check their credentials before following their advice and if you're having a serious issue, check with your current dentist. Dan. Will, thank you and thanks for telling us that you haven't been going to the dentist. Whit has asked me to call you yuck mouth from now on. I'm not sure what that means. I did not say that. You can work it out with him. I'm sharing myself with you, come on. Thank you. Appreciate it.
