The Truth About Citric Acid and Teeth: How to Enjoy Gannan Oranges Without Damaging Enamel
Citric acid is a natural component of all citrus fruits, including Gannan oranges. It can temporarily soften tooth enamel, making it more susceptible to wear. The key to protection is managing the acid's contact time with your teeth.
How can I enjoy Gannan oranges without harming my teeth?
Eat oranges with meals rather than as a standalone snack. Drink water while eating to help rinse acid away. Wait at least 30 minutes after eating before brushing your teeth, as brushing softened enamel can cause damage. Consider using a fluoride mouthwash to help remineralize enamel.
