4 Foods that Cause the Teeth to Decay!
September 11, 2025

You know that soda pop and sugary candies aren’t the best choices when it comes to your oral health. By limiting these treats, you can give your enamel a break. However, there are many other foods and beverages that you likely consume often that also have negative effects on your teeth. You may not even know that they are harmful. Here are some of the unsuspected cavity-causing foods and drinks that you should be wary of.
Raisins
Raisins provide various nutritional benefits and make delicious snacks. They are packed with healthy fiber, vitamins, and minerals. However, as for your oral health, they can go more harm than good. Raisins have a high sugar content. The bacteria in your mouth love eating away at sugar, so you are more likely to develop tooth decay. The thing that makes raisins even worse is that they are sticky, so they don’t easily wash away with water. This is definitely a snack to save for occasions.
Alcoholic Drinks
The main issue with alcoholic beverages is that they dry out your mouth. This happens because alcohol dehydrates your body, leading to lower salivary production. Saliva is necessary for your mouth to stay healthy. It helps to neutralize harmful acids in the mouth and wash away food particles and bacteria. When your mouth is dryer than normal, it becomes the perfect breeding ground for bacteria. If you drink, you are more likely to experience halitosis and tooth day. By limiting your alcohol intake, you can promote a healthier smile.
Saltine Crackers
It’s officially soup season! A favorite addition to a hot bowl of your favorite soup is some saltine crackers. Whether you prefer clam chowder, tomato basil, or chicken noodle, having something crunchy to acquaint it is a plus. However, the carbohydrates in saltine crackers turn to sugar in the mouth, resulting in the growth of bacteria. Starchy snacks are pretty much as bad for your teeth as sugar. Ultimately, you are more likely to develop cavities.
Cough Syrup
Being sick is no fun. Fortunately, there are cough syrups available to help soothe your sore throat and relieve your cough. However, they aren’t doing too much for your smile. There is a lot of sugar in this product, fueling the growth of bacteria. Ingredients like citric acid can also wear down the protective enamel of your teeth, putting them at risk for decay. Look for a sugar-free option and make sure to rinse your mouth out with water afterward.
Next time you consume the items above, be sure to consider your oral health. By being mindful, you can make the best decisions for your oral and overall health.
