What’s the “one tooth” challenge?

   It’s a trend where users position their lips so it looks like they only have one tooth. Faraz explains, “The one tooth challenge on TikTok is a challenge where creators film themselves moving their lips in a way that only shows one tooth through their smile.” There’s no specific reason why people are giving themselves one tooth, but it’s a fun and silly challenge that anyone can attempt in their spare time!

   • “Users will typically caption their posts with ‘Giving myself 1 tooth’ and film the process of them fixing their smile until only one tooth is visible,” says Faraz.
   • Most users post their “one tooth” challenge videos with the haunting classical audio “Take a Chance” by SANUSI HAMZAH. Faraz notes that the trend is also often accompanied by the sound ‘In Game’ (From ‘Granny’).
   • While the origin of the “one tooth” challenge is unclear, it has been gaining popularity on TikTok, probably due to videos from celebrities and influencers. Faraz says this video posted by user @Pinkmaine may have popularized the challenge.

1. 
   Purse your lips and leave a gap in the center so only one tooth is visible. Press your lips together and outward, like you’re making a kissy face, but leave a small space in the center for your tooth. Adjust the purse of your lips, bringing them closer or further apart until only one of your front teeth is showing. Film your attempt on your phone, then post the video to TikTok or your preferred social media platform!

   • If your teeth are on the larger side, this challenge may be tricky for you.
   • You can always take a photo, then add a single tooth sticker or emoji to the center of your mouth. Just make sure the tooth is large enough to stand out and look comical.

1. 1
   Vampire fangs In this viral Halloween trend, users attach costume vampire fangs to their actual teeth using superglue or nail glue. According to dentists, it’s definitely not safe (and not the brightest idea) since these types of glue aren’t meant for oral use. Superglue contains toxic additives, which can inflame your gums, damage your tooth enamel, and lead to other serious dental issues.

   • For a safer alternative, attach your costume fangs with a dab of denture adhesive cream.
2. 2
   DIY teeth filing This dangerous trend involves users filing the bumps and ridges on the bottom edges of their teeth with a nail file. Supposedly, it levels out any uneven teeth and gives you a more uniform smile, without requiring a visit to the dentist. However, dentists do not recommend filing your teeth at home since it can cause significant and permanent damage, including tooth sensitivity, discoloration, nerve damage, and even infection.

   • If you feel self-conscious about your teeth, consult with a dentist for a personalized treatment plan. Tooth contouring, cosmetic bonding, veneers, and Invisalign are common solutions.
3. 3
   Closing gaps with hair ties Some TikTok users have taken braces into their own hands, placing small elastic hair ties around their teeth to “align” them. This method isn’t effective because your teeth are stronger than hair ties, and it’s also dangerous—if these ties snap or fall off, you could potentially choke on them.

   • Additionally, this DIY method could cause gum inflammation or infection, so it’s best to visit a dentist if you have crooked teeth.
4. 4
   Whitening teeth at home While at-home whitening doesn’t seem as dangerous as other TikTok teeth trends, it can cause serious damage. Some users are making their own whitening strips with hydrogen peroxide or applying bleach directly to their teeth. This can cause pain, soreness, burns, tooth and gum sensitivity, and irritated or inflamed gums.

   • If you want to get whiter teeth at home, use ADA-approved whitening strips or whitening toothpaste.
