**Sour Candies: Fun to Eat but Risky for Your Teeth**
Sour candies might make you laugh, squirm, or pucker your lips — but dentists warn they can seriously damage your teeth. These popular treats are more than just fun and flavorful. According to dental experts, they’re also a big reason behind weakened tooth enamel and cavities.
Dr. Nadine Tassabehji, a dental professor at Tufts University in Boston, explains that sour candies are especially harmful because they combine sugar with strong acids. While all candy can be bad for your teeth, sour candies are worse due to their high acid levels.
### What Makes Sour Candies So Harmful?
Ingredients like citric acid, malic acid, tartaric acid, and fumaric acid give sour candies their distinctive punch. Unfortunately, these acids are harsh on your enamel — the hard outer layer that protects your teeth.
When you eat candy, the sugar makes your mouth more acidic. In response, your body tries to neutralize this by pulling minerals like calcium from your teeth. This process weakens the enamel and makes your teeth more prone to developing holes and decay.
The problem becomes even bigger with sticky candies such as sour gummies. Because they cling to your teeth longer than other sweets, the sugar and acid have more time to attack your enamel. Dr. Tassabehji calls this “a recipe for trouble.”
### The Rising Popularity of Sour Candies
Despite these risks, sour candies have become more popular than ever. Over the past 10 years, sales of sour candies have jumped by about 70%. This surge is partly fueled by viral trends on TikTok and YouTube, where kids and teens participate in “sour candy challenges” to see who can handle the most intense sour flavor.
Even adults enjoy sour treats. A 2024 study from Penn State University found that 1 in 8 adults prefers very sour flavors. Some social media posts even claim sour candy helps reduce anxiety, although there’s no scientific evidence to support this.
### How to Protect Your Teeth After Eating Sour Candy
If you think brushing your teeth immediately after eating sour candy will solve the problem, think again. Dr. Tassabehji advises against brushing right away because your mouth is already acidic. Brushing at that time can spread the acid around and speed up enamel damage.
Instead, the best first step is to rinse your mouth with water. This helps wash away the acid. If candy gets stuck between your teeth, floss to remove it. Drinking milk or other dairy products can also help, as they contain calcium and minerals that neutralize acid quickly.
After consuming sour candy, wait at least 30 minutes before brushing with fluoride toothpaste. This pause allows your mouth to calm down and your enamel to start repairing itself.
### Not All Sour Foods Are Bad
Dr. Tassabehji points out that not all sour foods are harmful. Fermented items like pickles, sauerkraut, and kombucha are actually beneficial for your digestion. However, sour candies “are just sugar and water,” she says. Their sour flavor comes from added acids and artificial flavorings, not natural ingredients.
### Final Thoughts
In short, sour candies may be tasty and trendy, but they are no friend to your teeth. If you enjoy them occasionally, take extra care with your dental hygiene afterward. Remember, sometimes the things that taste fun can have sour side effects on your health.
