What Soda Really Does to Your Teeth
Ever seen those videos where someone drops a baby tooth in a glass of soda and watches it decay? While the effect in your mouth isn’t quite as dramatic, the damage is still very real. Your saliva helps rinse sugar away, and daily brushing removes some plaque—but even with these defenses, soda can still take a serious toll on your oral health. That’s why we only recommend it as an occasional treat. Here’s what you need to know:
Sugar Feeds Harmful Bacteria
Soda is loaded with sugar—often more than your daily recommended intake in just one can. The bacteria in your mouth feed on sugar and produce acid as a byproduct. That acid is what breaks down your tooth enamel, leading to cavities. The more sugar you consume, the more fuel those bacteria have to cause decay.
Acids Weaken Tooth Enamel
Even if you opt for diet soda, you’re not in the clear. Diet sodas often contain acids like phosphoric acid or citric acid, which are just as harmful. These acids erode enamel over time, making teeth more vulnerable to decay, sensitivity, and staining.
Artificial Colors Can Stain Teeth
Many sodas include artificial dyes like caramel color and Yellow 5, which can stain your teeth. If a bright, white smile is important to you, it’s best to avoid these colored beverages.
Healthier Alternatives to Soda
Instead of soda, try sparkling water or plain water with fresh fruit slices for flavor. If you do indulge in soda occasionally, rinse your mouth with water afterward. And of course, stick to regular brushing, flossing, and dental checkups to keep your smile healthy and strong.
