If you followed the 2026 Winter Olympics, you likely noticed Team USA figure skating star Alysa Liu. The 20-year-old captured global attention by winning gold in the women’s singles on February 19, adding to her team gold earlier in the Games. Her victory marked a historic moment—she became the first American in 24 years to win Olympic gold in individual women’s figure skating and the first U.S. medalist in the event since 2006.

Liu’s achievement was even more remarkable considering she returned to competition in 2023 after nearly two years of retirement due to burnout following the Beijing Olympics. While her skating impressed audiences worldwide, an unusual detail about her appearance quickly went viral. During celebrations, cameras caught a glimpse of small silver spikes above her teeth—revealed to be a “smiley” piercing, a piece of jewelry placed through the thin tissue connecting the upper lip to the gum, visible mainly when smiling.

Liu previously shared that she performed the piercing herself with help from her sister more than two years ago. The revelation sparked widespread online interest, with many fans curious about the trend. However, dental professionals are now warning against attempting such piercings—especially at home.

The American Dental Association cautions that oral piercings carry serious risks because the mouth contains large amounts of bacteria. Possible complications include infection, swelling, bleeding, scarring, gum and tooth damage, and even choking if jewelry breaks loose. In severe cases, swelling could interfere with breathing, and repeated contact with teeth may cause cracks or long-term damage.

Experts strongly advise consulting a professional and considering removal if problems arise. While Liu’s Olympic triumph inspired many, health specialists emphasize that safety should come before trends.
