What Foods To Avoid if you have Calcium Deposits on Teeth?
If you’re dealing with calcium deposits on your teeth—more commonly known as tartar—you’re not alone. Tartar is hardened plaque that forms on your teeth over time and can cause issues like tooth discoloration, gum disease, and even tooth decay. It’s caused by the combination of bacteria, saliva, and certain foods, and while regular brushing and flossing can help, your diet also plays a huge role in preventing it.
In this post, we’ll dive into the foods you should avoid if you have calcium deposits on your teeth. We’ll explain why these foods are problematic, give you better alternatives, and provide actionable tips on how to keep your smile healthy. Let’s start by answering the question: What foods should you avoid to keep your teeth tartar-free?

1. Sugary Foods and Drinks – The Top Culprit of Tartar
Why It Matters: Sugary foods and drinks are the primary fuel for harmful bacteria in your mouth, especially Streptococcus mutans. This bacteria loves sugar and ferments it to produce lactic acid. This acid is the main culprit behind plaque formation, which, over time, mineralizes and turns into tartar. The more sugar you eat, the more acid your mouth produces, and the faster plaque turns into hard, stubborn tartar.
Biochemical Mechanism: Enzymes like amylase break down starches into sugars in your mouth, which bacteria feed on. Streptococcus mutans ferments these sugars into lactic acid, causing the pH of your mouth to drop and triggering enamel demineralization. This leads to plaque buildup, which eventually becomes tartar.
Examples of Sugary Foods to Avoid:
- Sodas and sugary drinks (including diet sodas)
- Candy, particularly chewy or hard candies
- Sweetened cereals and granola bars
- Baked goods like cakes, cookies, and pastries
- Fruit juices with added sugar
Better Alternatives:
- Opt for unsweetened beverages like water, herbal teas, and black coffee.
- Snack on whole fruits like apples, pears, and watermelon instead of sugary treats.
- Choose whole grains like brown rice, quinoa, and oats instead of refined breakfast cereals.
- For a sugar substitute, try stevia or monk fruit.
2. Acidic Foods – The Enemies of Your Enamel
Why It Matters: Acidic foods and drinks, such as citrus fruits and soft drinks, can erode your enamel over time. When enamel is worn down, it becomes more susceptible to plaque buildup. As plaque hardens, it turns into tartar, which is much harder to remove than regular plaque. Additionally, the acid in these foods can further irritate your gums and lead to tooth sensitivity.
Biochemical Mechanism: Acidic foods cause demineralization, where minerals like calcium and phosphate are leached out of the enamel. This weakens your teeth and makes them more prone to plaque accumulation. When enamel is compromised, bacteria can invade and mineralize plaque into tartar.
Examples of Acidic Foods and Drinks to Avoid:
- Citrus fruits (lemons, oranges, grapefruits)
- Vinegar-based dressings and sauces
- Wine (especially white wine)
- Soda (even diet sodas)
- Energy drinks and fruit juices with high acid content
Better Alternatives:
- Drink water or milk, which can help neutralize acids and strengthen enamel.
- Instead of citrus fruits, try watermelon or bananas, which are gentler on your teeth.
- Opt for herbal teas without added sugar.
- Choose smoothies with low-acid fruits like peaches and blueberries.
3. Sticky Foods – The Plaque Traps
Why It Matters: Sticky foods like dried fruits and chewy candies cling to your teeth, allowing bacteria to feast on them for a longer period. This prolonged exposure to sugars and acids increases the chances of plaque buildup. The longer the food stays on your teeth, the more likely it is that plaque will harden into tartar.
Biochemical Mechanism: Sticky foods tend to linger on your teeth longer than non-sticky ones, giving bacteria more time to feed on the sugars and produce acids. This results in the continuous production of acids that demineralize your teeth and create a perfect environment for plaque to turn into tartar.
Examples of Sticky Foods to Avoid:
- Dried fruits like raisins, apricots, and figs
- Fruit snacks and gummy bears
- Granola bars and energy bars
- Peanut butter and other sticky nut butters
Better Alternatives:
- Fresh fruits like apples, pears, and cucumbers, which help naturally clean your teeth.
- Raw vegetables such as carrots, celery, and bell peppers, which have a crunchy texture that can help scrub teeth clean.
- Yogurt or cottage cheese, which have a smoother texture and contain calcium, a mineral that strengthens enamel.
4. Refined Carbs – The Silent Enemies of Your Smile
Why It Matters: Refined carbohydrates, such as white bread and pasta, quickly break down into sugars once digested. These sugars contribute to acid production in your mouth, encouraging the formation of plaque and tartar. The high glycemic index of refined carbs can spike your blood sugar levels and, in turn, increase plaque formation.
Biochemical Mechanism: Refined carbs break down into simple sugars quickly, which are fermented by bacteria into acids. These acids then contribute to enamel demineralization and the subsequent buildup of plaque, which eventually turns into tartar.
Examples of Refined Carbs to Avoid:
- White bread and pasta
- Chips and crackers made from refined flour
- Pastries, cookies, and cakes
- Processed snack foods
Better Alternatives:
- Choose whole grain options like quinoa, brown rice, and whole-wheat bread.
- Snack on nuts, seeds, and vegetables to avoid refined carb intake.
- Opt for whole-grain pasta or rice noodles instead of their refined counterparts.
5. Hidden Sugars – The Foods That Lurk in the Background
Why It Matters: Hidden sugars are often found in processed foods, sauces, and snacks that seem healthy but are packed with added sugars. These sugars contribute to plaque formation in the same way as sugary drinks and candies. It’s essential to read labels carefully to avoid these hidden culprits.
Examples of Hidden Sugars to Watch Out For:
- Ketchup, barbecue sauce, and salad dressings
- Flavored yogurts (even those labeled “low-fat” or “healthy”)
- Processed granola and snack bars
- “Healthy” fruit snacks and smoothies
Better Alternatives:
- Make your own salad dressings using olive oil, vinegar, and herbs.
- Choose unsweetened yogurt and add fresh fruit for sweetness.
- Snack on whole fruits and vegetables instead of processed snacks.
- Use natural sweeteners like stevia or monk fruit in recipes.
What Else Can You Do Besides Avoiding These Foods?
Here are some additional tips to prevent tartar buildup and keep your teeth healthy:
- Brushing Techniques: Use a soft-bristled toothbrush and brush at a 45-degree angle to the gum line. The Bass technique is highly recommended for thorough cleaning.
- Flossing: Floss daily to remove food particles and plaque between your teeth. Waxed floss is easier to use for those with tight spaces.
- Chewing Sugar-Free Gum: Gum with xylitol can increase saliva production, which helps neutralize acids and wash away food particles.
- Hydration: Drink plenty of water to help rinse food particles and bacteria from your mouth, and to keep your saliva flowing.
conclusion:
Avoiding sugary, acidic, sticky, and refined foods is crucial to preventing tartar buildup on your teeth. By following the tips outlined in this post and making healthier food choices, you can help protect your smile and avoid costly dental treatments. Remember, regular brushing, flossing, and hydration also play a key role in maintaining your oral health. Always consult your dentist for personalized advice and professional care.
