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.^{[1]

- For a safer alternative, attach your costume fangs with a dab of denture adhesive cream.

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.^{[2]

- 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.

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.^{[3]

- Additionally, this DIY method could cause gum inflammation or infection, so it’s best to visit a dentist if you have crooked teeth.

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.^{[4]
