When watching what we eat, we often think about our weight, hearts, or energy levels. But the truth is, what you eat doesn’t just affect your body. It also plays a big role in your oral health. Some of your favorite foods might taste great, but eating too much can damage your enamel. Over time, this can lead to cavities and even bigger dental issues. Knowing which foods to watch out for is key to keeping your smile healthy and strong.
Here are some of the foods that cause cavities.
Sugary Foods
Everyone knows that sugar is bad for your teeth, but in the past, people didn’t always understand that way. Now, science confirms that sugar does cause tooth decay. However, sugar itself isn’t the main problem. What happens afterward is what really matters.
Your mouth hosts many types of bacteria. Some bacteria are good for your dental health, while others are not.
Research shows that harmful bacteria create acid in your mouth when you’re digesting sugar. This acid strips minerals from your tooth enamel in a process known as demineralization.
Fortunately, your saliva can help repair this damage through remineralization. The minerals in your saliva, like calcium and phosphate, and fluoride from toothpaste and water, help the enamel rebuild by replacing the minerals lost during acid attacks.
Repeated acid attacks can lead to mineral loss in the enamel. Over time, this weakens and damages the enamel, resulting in a cavity. A cavity is a hole in the tooth caused by decay, which happens when harmful bacteria break down sugar and produce acids. If you don’t treat it, the cavity can extend deeper into the tooth, causing pain and potentially leading to tooth loss.
Signs of cavities include:
- A toothache
- Discomfort while chewing
- Sensitivity to hot, sweet, or cold drinks and foods
Sugar Attracts Harmful Bacteria and Decreases the pH level in the Mouth
Sugars are like a magnet for bad bacteria. These bacteria thrive on the sugar you consume and create dental plaque, a sticky, colorless film that settles on your teeth. If you don’t wash away the plaque by brushing, your mouth becomes more acidic, and cavities can form.
The pH scale tells us how acidic or basic something is, with seven being neutral. When plaque’s pH drops below 5.5, the high acidity dissolves minerals and damages your tooth enamel.
Sugar is present in more foods than you might realize. You can find it in:
- Natural sources like vegetables, fruits, and honey
- Processed treats like cakes
Foods high in white processed sugar are particularly harmful because they leave a sticky film on your teeth that saliva can’t easily wash away. The only way to eliminate this residue is by brushing, flossing, using mouthwash, and getting dental cleanings.
While you should enjoy sugars in moderation, snacking frequently on sugary foods can extend the time your teeth remain exposed to the damaging effects of acids, ultimately resulting in decay.
Effects of Sugary Drinks
Drinking sugary drinks can be worse for your teeth than eating sugary foods. Besides the sugar, many drinks like soda have acids that hurt your teeth.
Drinks with high-fructose corn syrup are especially bad. This sweetener, found in many sodas and other sugary drinks, coats your mouth with harmful substances and creates a sticky layer on your tongue. Bacteria love this layer, producing acids that can lead to cavities.
Sticky Foods
Sticky foods often have sugar, and eating too much sugar is a major cause of tooth decay. These sticky treats cling to your teeth, allowing sugars to penetrate your enamel and cause damage. The best way to avoid this is to steer clear of sticky foods. If you choose to indulge, make sure to visit your dentist regularly.
What Exactly Are Sticky Foods?
Sticky foods are anything chewy or gummy that sticks to your teeth. If you enjoy dried fruit, try eating fresh fruit instead because dried fruit is stickier and has more sugar.
Who doesn’t love caramel? You can find it in candy, on healthy apples, in popcorn or ice cream, and in many desserts. Toffee is similar to caramel, so keep an eye on it when considering sticky foods.
Even peanut butter, a daily favorite, can stick to your teeth. You can enjoy it, but try to choose one with low sugar. Sticky foods like jelly, syrup on waffles, marshmallows in hot chocolate, or what you thought was a healthy box of raisins all contain sugar that clings to your teeth, which can be harmful. Do you have to give up these foods forever? No, but it is a good idea to limit them and opt for healthier choices like fresh veggies, fruits, nuts, seeds, low-sugar yogurt, or cheese.
Acidic Drinks and Foods
The enamel on your teeth can wear down if you regularly eat or drink acidic stuff. Your enamel protects your teeth from everyday wear and tear. Without it, you’d be more vulnerable to damage while brushing and eating.
However, when you frequently consume acidic foods and drinks, you weaken your enamel. That makes you more susceptible to cavities and gum disease.
Examples of acidic foods and drinks include:
- Citrus fruits — Citrus fruits such as oranges are often enjoyed during meals. However, eating too many acidic foods can harm your dental health. It’s wise to balance these with less acidic options. Some people find that having an orange in the morning boosts their well-being because Vitamin C supports their immune system. Still, you might want to think about limiting how many acidic foods, like oranges, you eat
- Fizzy drinks — Many fizzy drinks contain phosphoric acid, which causes them to be fizzy and high in acidity. If you drink fizzy beverages, do so occasionally. Whenever you can, try swapping them for healthier choices like water
- Soft drinks — It’s not just the fizzy ones that cause cavities. You should be mindful of your intake of lemonade, fruit juice, and cordial
What is a Healthy Amount of Acidic Foods and Drinks?
There isn’t a set amount that defines a healthy intake of acidic foods and drinks. It’s all about finding the right balance with non-acidic options so you enjoy more of those! If your diet relies heavily on acidic items, it could negatively impact your teeth, so aim to cut back if you can. Also, it’s essential to not only limit your consumption but also reduce exposure. For example, avoid brushing your teeth right after eating something acidic because the acids can linger and erode enamel for up to 20 minutes. If you can wait that long before brushing, it would be helpful.
Starchy Foods
You’ve probably noticed that candy and sugary snacks are bad for your teeth, but many people don’t realize that starchy foods can be just as harmful. Foods like bread, potato chips, and pasta contain sugars that aren’t obvious at first glance.
But they can damage your teeth just like candy does.
Carbohydrates and Simple Sugars
Carbohydrates like bread and potato chips start as starches but become simple sugars in your mouth. Some carbs break down quickly while chewing; others take longer to digest. The sugars that form in your mouth stick to your teeth until you brush your teeth. Like the sugars in your favorite candies, these carbs can feed the bad bacteria in your mouth, leading to tooth decay.
Carbs don’t cause cavities immediately. They start forming when you leave them on your teeth for too long without brushing. The longer food stays on your teeth, the more it attracts harmful bacteria, which increases acid production. Foods that stick to your teeth or get trapped in the crevices of your mouth are especially risky since they’re harder to remove.
You can still enjoy carbs and snack on potato chips now and then. Keep in mind that carbs can impact your dental health. While eating carbs, sip on some water to help rinse off the sugars, and brush your teeth as soon as possible afterward. That helps reduce the time sugars and bacteria have to produce harmful acids that can cause tooth decay.
Drying Drinks and Foods
When it comes to drying foods, we all know that eating too much sodium can increase our chances of high blood pressure, strokes, and heart problems. But you might not know that sodium, similar to sugary snacks, can also irritate your teeth.
While salt doesn’t damage tooth enamel directly, sodium and carbs can be problematic, especially in processed foods. When you eat or drink items with carbs, oral bacteria consume the simple sugars and release strong acids. The longer those acids linger in your mouth, the more damage they can do to your enamel.
Sodium can weaken your teeth, too. Your teeth, like bones, need calcium to grow strong and stay healthy. Foods high in sodium can lead to losing more calcium through urine, which can contribute to osteoporosis and tooth loss.
Other dehydrating drinks, like alcohol, can dry you out by lowering the production of the Antidiuretic hormone, which regulates how much urine you produce. Consuming alcohol makes your kidneys filter out more fluids than normal, leading to dehydration. That can shrink your salivary glands and reduce saliva flow.
After drinking, many people experience dry mouth, also known as xerostomia. This condition can worsen periodontitis, a gum disease characterized by plaque buildup, bleeding gums, gum recession, infections, and pockets forming where the gums pull away from the teeth.
Alcohol negatively affects dental health beyond just the gums. People who struggle with alcohol addiction face a higher risk of oral health issues. Heavy drinkers are three times more likely to lose teeth permanently, especially with high plaque levels.
Making Smart Food Choices for Your Dental Health
You can enjoy various foods mentioned in this blog in moderation and prevent tooth decay. The trick is identifying foods that can cause problems, maintaining a good hygiene routine, and visiting your dentist regularly to catch early signs of decay.
If you want to eat foods that might lead to tooth decay but want to minimize the risk, try these tips:
- Brush or floss after eating — Brush your teeth after every meal and snack. Flossing after meals can also help. If you’re short on time, using travel mouthwash can reduce sugar, acid, starch, and bacteria in your mouth
- Add alkaline foods to your diet — Incorporating alkaline foods like broccoli, cabbage (not pickled), spinach, peppers, and other leafy greens can lower your risk of tooth decay
- Eat calcium-rich foods — Foods high in calcium, like dairy, nuts, and seeds, can strengthen your teeth and bones, even if some contain acid. You might also consider calcium supplements and non-acidic calcium-rich foods such as kale
- Use whitening toothpaste — Foods and drinks that cause stains can also lead to tooth decay since they stick to your teeth. Using a whitening toothpaste can help prevent stains while strengthening your teeth
You don’t have to cut out every food you love to avoid cavities. The trick is to keep it balanced. You can have some sweets or snacks in moderation. Plus, don’t forget to take care of your teeth.
Can You Prevent Cavities?
You can prevent cavities if you catch them early. If you see that your tooth enamel is starting to weaken, you can take action to stop cavity-causing bacteria from settling in. That means watching what you eat, improving your dental care routine, and using fluoride toothpaste or mouthwash.
If a cavity has progressed and worn down the enamel to the dentin, you should see a dentist. It’s important to act quickly when you find a cavity because smaller, less developed cavities are much easier to treat than abscesses or tooth infections.
