Pumpkin spice lattes may be a fall favorite, but their high sugar content and acidity can weaken enamel, increase the risk of tooth decay, and cause staining, according to research from the Canada-based dental clinic Inglewood Family Dental.
With these potential risks, dentists are warning patients to drink the fall treat in moderation.
"Pumpkin spice lattes are a delicious fall treat, but the combination of sugar and acidity can be harmful to your teeth if consumed too often," Dr. Arash Ravanbakhsh of Inglewood Family Dental, said in a story.
Furthermore, global Google searches for "DIY pumpkin spice latte" have surged by 61%. With its growing popularity, dental professionals should warn patients about the potential oral health risks associated with the drink, they wrote.
Pumpkin spice lattes are packed with sugar, which feeds harmful bacteria in the mouth that produce acids, eroding tooth enamel and leading to cavities. A standard serving contains 50 g of sugar, exceeding the recommended daily limit for both adults (30 g) and children (24 g), according to the story.
In addition to the high sugar content, the drink's acidic coffee base further weakens enamel, making teeth more vulnerable to decay. Frequent sipping prolongs acid exposure, accelerating enamel erosion, while coffee, spices, and syrups can cause staining over time. Toppings like whipped cream and caramel drizzle add even more sugar, increasing the risk of plaque buildup and tooth decay.
Dental professionals should recommend rinsing with water to remove leftover sugars and acids and using a straw to minimize direct contact between the drink and teeth. Additionally, to reduce sugar intake, consider sugar-free syrup alternatives, they wrote.
"Taking these steps can help you enjoy fall flavors without compromising your smile," Ravanbakhsh said.
