Best Foods for Healthy Teeth
Is what you eat good for your teeth? Find out which foods help promote healthy teeth and gums.
A varied diet, water as your usual drink, and fewer frequent sugary snacks can support dental health. Food choices work alongside brushing, cleaning between teeth, and dental examinations; no food or supplement treats a cavity or replaces care for gum disease.
Which foods support healthy teeth and gums?
Build meals around a variety of vegetables, fruit, protein foods, and sources of calcium. Whole fruit usually makes a more useful snack than repeatedly sipping juice. Plain dairy foods or suitable fortified alternatives can contribute calcium; check labels for added sugar. Choose foods that fit your medical needs, allergies, and ability to chew.
Why does how often I snack matter?
Repeated exposure to sugary drinks and snacks gives the mouth less time between acid challenges. Consider the pattern across your day, including sweetened coffee, sports drinks, juice, and foods that linger around teeth. Water with meals and between meals is a practical starting point. Read our sparkling-water guide if flavored or carbonated drinks are part of your routine.
Can low vitamin C cause bleeding gums?
Severe vitamin C deficiency can affect gum health, but bleeding gums have several possible causes, including plaque-related inflammation. Do not assume that a supplement will solve the problem. A limited diet is worth discussing with your medical clinician; persistent bleeding also deserves a dental examination. Peppers, kiwifruit, broccoli, and strawberries are examples of foods containing vitamin C.
Should I take vitamins for my teeth?
Discuss supplements with your clinician if you have a deficiency, restricted diet, medical condition, or difficulty eating. Taking extra vitamins without identifying a need is not a substitute for dental treatment. Bring a list of supplements and medications to your appointment, especially if you receive care for complex medical needs.
What else helps prevent cavities?
Brush with fluoride toothpaste and clean between teeth each day. Our toothpaste guide explains how to compare products. Dry mouth changes cavity risk, so tell us if eating or swallowing feels dry; see our dry-mouth information.

8 Foods to Avoid If You Have Sensitive Teeth
Leaving certain foods off of your menu — think hot, cold, sugary, sticky, and acidic — may help ease tooth sensitivity.
Having sensitive teeth is common: As many as 40 million Americans report having some pain in their teeth when eating or drinking hot, cold, acidic, sticky, or sugary foods, according to the Academy of General Dentistry (AGD). Women and young adults as well as those with receding gum lines reported the most tooth sensitivity in a study of nearly 800 patients at dental practices in the northwestern United States that was published in The Journal of the American Dental Association in March 2013.
While foods that are very hot or very cold can cause tooth pain, avoiding these eight foods in particular may help you find relief:
1. Soda. This is one of the top foods to avoid for sensitive teeth, says John T. Grbic, DMD, a professor of dental medicine and director of the division of foundational sciences at Columbia University College of Dental Medicine in New York City. Soda has two ingredients that can irritate exposed teeth nerves: sugar and acid, he says, "so it’s a double whammy.”
2. Ice cream. “Ice cream is not only cold, but it has sugar that can cause teeth to be more sensitive,” says Jordan Taylor, DMD, a dentist with Stonecreek Dental Care in Huntsville, Alabama. People with sensitive teeth lack the enamel layer that acts as a protective barrier. “Without that layer of enamel to insulate your nerves, the temperature of the food can be more aggravating,” he says.
3. Hot coffee. Hot foods can also cause your teeth to hurt, and sweetening your steaming coffee with sugar can make pain even worse. Dr. Taylor suggests adding some milk to your coffee. The milk helps to slightly lower the temperature of the coffee as well as its acidity, so it’s less damaging to your teeth, he says.
4. Hard candy. When you have sensitive teeth, skip hard candy such as lollipops, peppermints, and suckers. Not only are they full of sugar that can cause tooth pain, but they could also cause teeth to chip or break, according to the American Dental Association.
5. Sticky candy. These sweet treats, such as toffee, caramel, gummy bears, and licorice, have a few strikes against them, especially for people with tooth sensitivity. Besides being full of sugar, they can stick to your teeth.“Extremely sweet and sticky foods can stimulate the nerves in the dentine, which is similar to tooth enamel but not as hard, and has tiny microscopic holes to further expose the nerves,” says Eugene Gamble, MClinDent, a periodontics specialist and oral surgeon in the United Kingdom.
6. Citrus fruits. Pineapple, grapefruit, lemons, and limes are all highly acidic fruits, and the acid can make your teeth more sensitive, according to the AGD. This is because they wear away at tooth enamel. Keep in mind that both eating these fruits and drinking the fruit juice can trigger tooth sensitivity and pain.
7. Tomatoes. Although tomatoes are a good source of vitamins, especially vitamin C, they're also highly acidic, so be sure to avoid them if your teeth are sensitive, says Victoria Veytsman, DDS, of Cosmetic Dental Studios in New York City. Note that tomato sauce as well as raw tomatoes can trigger tooth sensitivity.
8. Ice. Even if you can tolerate cold drinks, resist the habit of chewing ice, Dr. Grbic says. Ice can be problematic for sensitive teeth, because it's both cold and hard.
If you have sensitive teeth and symptoms persist for more than a few weeks or become unbearable, be sure to talk to your dentist. Sensitive teeth may be a sign of a more serious health issue, such as a cavity or abscess that needs to be treated, according to the Oral Health Foundation.
Is Sparkling Water Bad for My Teeth?
Is the satisfying fizz of your favorite sparkling water putting you at risk for tooth decay? Because any drink with carbonation—including sparkling water—has a higher acid level, some reports have questioned whether sipping sparkling water will weaken your tooth enamel (the hard outer shell of your teeth where cavities first form).

So, Is Sparkling Water Affecting My Teeth?
According to available research, sparkling water is generally fine for your teeth—and here's why. In a study using teeth that were removed as a part of treatment and donated for research, researchers tested to see whether sparkling water would attack tooth enamel more aggressively than regular lab water. The result? The two forms of water were about the same in their effects on tooth enamel. This finding suggests that, even though sparkling water is slightly more acidic than ordinary water, it's all just water to your teeth.
Tips for Enjoying Sparkling Water—and Protecting Your Teeth
- Sparkling water is far better for your teeth than sugary drinks. In addition, be sure to drink plenty of regular, fluoridated water, too—it’s the best beverage for your teeth. Water with fluoride naturally helps fight cavities, washes away the leftover food cavity-causing bacteria feast on and keeps your mouth from becoming dry (which can put you at a higher risk of cavities).
- Be mindful of what’s in your sparkling water. Citrus-flavored waters often have higher acid levels that does increase the risk of damage to your enamel. Plan to enjoy these in one sitting or with meals. This way, you aren’t sipping it throughout the day and exposing your teeth over and over again to the slightly higher level of acid it contains.
- Sparkling water brands with added sugar can no longer be considered just sparkling water. They are a sugar-sweetened beverage, which can contribute to your risk of developing cavities. So remember—sparkling or not—plain water is always the best choice.
6 Ways to Reduce Your Child’s Sugary Snacking (and Save Their Smile)
Everyone knows a healthy diet is essential to a healthy life, but how many know that eating right can help prevent tooth decay and gum disease?
We all know that a balanced diet is essential for a healthy life, but as a parent, it can feel like a constant battle against the "sugar rush." In the dental world, we don't just look at sugar as a source of energy; we see it as the primary fuel for the bacteria that cause tooth decay and gum disease.
Protecting your child’s smile doesn’t require a complete pantry overhaul. Often, a few small, strategic changes to how and when your family snacks can make the biggest difference.
Here are six practical ways to reduce sugary snacking in your household.
1. Timing is Everything: The "Mealtime Rule"
It isn't just about how much sugar your child eats, but how often. Every time your child eats sugar, the mouth becomes acidic for about 20 minutes. Frequent snacking leads to constant "acid attacks."
The Fix: If they are going to have a sugary treat, let them have it with a meal. Increased saliva production during meals helps wash away sugar and neutralize acids.
2. Swap "Sticky" for "Crunchy"
Sticky snacks like fruit leathers, gummy vitamins, and dried fruit are some of the biggest culprits in pediatric cavities because they lodge in the grooves of the teeth and stay there for hours.
The Fix: Choose "detergent" foods—crunchy fruits and vegetables like apples, carrots, and celery. These naturally help scrub the tooth surfaces as they are chewed.
3. The "Water First" Strategy
Juice boxes and sports drinks are often marketed as healthy, but they are frequently loaded with liquid sugar that bathes the teeth.
The Fix: Make water the default beverage. In Jacksonville, our community water is fluoridated, which acts like a "constant repair kit" for tooth enamel. If they do have juice, have them chase it with a sip of water to rinse the teeth.
4. Become a Label Detective
Sugar hides under many names: high fructose corn syrup, agave nectar, maltose, and dextrose. Many "healthy" yogurts and cereals contain as much sugar as a candy bar.
The Fix: Look for snacks where sugar isn't one of the first three ingredients. Aim for snacks with less than 5 grams of sugar per serving.
5. Harness the Power of Cheese
It sounds simple, but cheese is a secret weapon for dental health.
The Fix: Cheese triggers saliva flow and contains calcium and phosphates that help re-mineralize tooth enamel. A string cheese or a few cubes of cheddar is an excellent "closer" for a snack or meal.
6. Model the Behavior
Children are observant. If they see you reaching for water and nuts instead of soda and cookies, they are more likely to follow suit.
The Fix: Make healthy snacking a family project. Let them help pick out "dentist-approved" snacks at the grocery store to give them a sense of ownership over their health.
A Note for Jacksonville Parents
Between school, sports, and Florida heat, kids are constantly on the go. While we advocate for healthy snacking, we also know that life happens. If your child does indulge in a sugary snack while you're out at San Marco Square or the park, just remember: Rinse with water immediately and brush as soon as you get home.
