Soda is an extremely popular drink in the U.S. that comes in countless varieties. Americans drink soda in cans, bottles, and giant styrofoam cups from the convenience store. Most people know that soda is bad for your teeth, but just how bad is it? It may actually be twice as bad as you may think. Soda increases the risk for cavities by contributing to two important parts of the cavity process. Here’s what you need to know.
At Rockland Dental Specialists, our periodontists and implant specialists help patients throughout Rockland County understand how everyday habits affect their oral health. Whether you’re managing cavity risk or have questions about tooth decay and enamel erosion, our general dentistry services are here to help.
Soda Is Full of Sugar
Soda damages teeth because of two things working simultaneously: sugar and acid. The sugar in soft drinks feeds harmful bacteria in your mouth, which then produce acid that dissolves enamel. Meanwhile, the soda itself introduces additional acid directly, lowering the pH in your mouth before bacteria even get involved.
Bacteria in dental plaque are responsible for causing cavities, and sugar contributes to the process because they feed the bacteria. As bacteria “eat” the sugar, they produce acid, and it is this acid that weakens and dissolves tooth enamel.
The more sugar you ingest, the more you feed the bacteria, and the more acid they can produce. Sodas and other sugary drinks are particularly dangerous because many people sip on them throughout the day, continuously supplying cavity-causing bacteria with fuel and allowing them to cause ongoing damage to the teeth. According to the CDC, the average American consumes far more added sugars than the recommended daily amount, and sugary beverages are a leading contributor.
Soda Is Highly Acidic
We mentioned that the cavity process involves feeding the bacteria sugar, with which they make acid. This acid makes enamel weak enough for bacteria to penetrate. Our body naturally defends against the cavity process by neutralizing the acid as much as possible. Saliva is alkaline in pH and counteracts these acids. Overall, the inside of the mouth should be neutral or alkaline.
When you drink soda, its low pH, anywhere from 2.7 — 4.5 on the pH scale, drastically reduces the pH inside your mouth. Sodas commonly contain phosphoric acid and citric acid, which give them their tangy flavor and contribute significantly to their corrosive potential. The stronger the acid, the more difficult it is for your mouth to return to a neutral pH and stay healthy.
In an acidic environment, cavity-causing bacteria thrive. When the pH inside the mouth is already low, the bacteria need to produce much less acid to penetrate the enamel. Basically, when you drink sodas throughout the day, you do half of the bacteria’s work for them. This is why even diet soda and sugar-free sodas still cause enamel erosion; the acid is still there even without the sugar.
Is Diet Soda Bad for Your Teeth?
Yes, diet soda is still harmful to your teeth, even without sugar. While removing sugar eliminates one source of acid from bacteria, the soda itself remains highly acidic. Diet sodas contain the same phosphoric and citric acids as regular soda, meaning they can cause enamel erosion and increase tooth sensitivity over time. The same precautions apply whether your soda has sugar or not.
How to Reduce the Damage Soda Causes
We know that many people are unwilling to give up their sodas. Fortunately, you can minimize the damage drinking soda does to your teeth by following a few steps. Each of the habits below makes a meaningful difference, especially when practiced consistently.
- Drink with a meal: When we eat, our body produces its highest amounts of saliva to help digest food. This saliva can counteract the effects of the sugars and acids in soda, making mealtimes the safest window to enjoy one.
- Drink quickly and use a straw: Sipping soda throughout the day keeps the pH in your mouth chronically low. Drink it quickly instead, and if possible, use a straw positioned toward the back of your mouth to minimize direct contact with your enamel. Follow with plain water to neutralize the pH.
- Chew sugar-free gum: Chewing sugar-free gum stimulates saliva production. If you drink a soda between meals, gum can quickly help counteract the acid, but it must be sugar-free.
- Wait before brushing: Brushing immediately after drinking soda can cause additional damage because enamel is temporarily softened by acid. Wait at least 20 to 30 minutes to let your saliva begin remineralizing the enamel first.
- See your dentist regularly: Your dentist will evaluate your cavity risk and make personalized recommendations. Professional fluoride treatments at each cleaning harden enamel after acid attacks, making teeth more resistant to future damage.
Making these habits part of your routine goes a long way toward protecting your smile, even if you are not ready to cut soda out entirely.
Beyond cavities, soda’s acidity can also irritate gum tissue, increasing the risk of gingivitis and gum disease over time. If left untreated, these conditions can contribute to tooth loss and more serious oral health issues. Staying current with periodontal maintenance is an important line of defense for anyone in Rockland County who regularly drinks soda.
