Dental experts have cautioned that sweet, sticky treats like the viral “Dubai jjondeuk cookie,” also known as Dujjonku, may harm oral health.
According to medical professionals, cavities form when bacteria in the mouth break down sugar in food, producing acid that erodes tooth enamel. Foods high in sugar generate more acid, while sticky foods prolong the exposure by adhering to teeth.
“Food residues left on teeth continuously feed cavity-causing bacteria, accelerating decay and contributing to tartar buildup,” said Lim Hyun-chang, a professor of periodontology at Kyung Hee University Dental Hospital. He added that ingredients in the Dubai jjondeuk cookie can remain lodged in narrow gaps or along the gum line, potentially causing gum inflammation.
Experts emphasize proper brushing for those who wish to continue enjoying the treat. Brushing within two to three minutes after eating is recommended. After consuming sticky foods, Lim suggests the modified Bass technique, which involves holding the toothbrush at a 45-degree angle and using gentle vibrating and sweeping motions to remove plaque along the gum line. He warned against forceful horizontal brushing, which can damage gums and enamel.
Brushing alone may not remove food trapped between teeth. Dental floss or interdental brushes can help, with Lim noting that flossing before brushing allows fluoride from toothpaste to better penetrate. Interdental brushes are particularly effective when spaces between teeth are wide.
