Introduction
Teeth are one of the strongest parts in the human body, designed to last a lifetime. However, even teeth can decay without proper care. A balanced diet is a must for overall good health but certain foods and drinks can cause harm to your teeth. Let’s look closely at the type of foods that can be destructive to your teeth.
The Science behind Tooth Decay
First and foremost, it’s important to understand how tooth decay occurs. Your mouth is home to many bacteria that thrive on sugars and starch in the food. As they digest the sugar, they produce acids that damage the protective outer layer of your teeth, the tooth enamel. With time, the acid erosion can cause cavities and serious dental issues.
Sweet foods and drinks
Sugar is the biggest cause of tooth decay. Sugary foods and drinks create a fertile ground for harmful bacteria to grow. For example:
- Candy (especially hard and chewy ones)
- Soft drinks
- Energy drinks
- Cakes
- Ice cream
- Sweetened foods and beverages
The longer these substances remain on your teeth, the longer these bacteria produce acids and attack the enamel. This is why candies and slowly consumed sweet foods and drinks can cause the most damage.
Acidic foods and drinks
As mentioned above, acidic foods would directly damage the tooth enamel, weakening your teeth and leaving them more vulnerable to decay. For example:
- Citrus fruits and juices
- Foods with vinegar
- Tomatoes and tomato-based sauces
- Carbonated drinks (sugar free too!)
- Sports drinks
- Wine
Since some of these foods have nutritional benefits, consume them in moderate amounts and rinse your mouth with water afterwards to protect your teeth.
Sticky and chewy foods
Sticky foods have the tendency to stick to your teeth and get lodged between your teeth. They may linger in the mouth, allowing the bacteria to attack your teeth for longer. Examples include:
- Caramel
- Toffee
- Gummy candies
- Dried fruit
- Peanut butter
- Potato chips
These foods can be especially damaging if consumed frequently or between meals, as snacks.
Starchy foods
Most people are not aware that starchy foods can also contribute to tooth decay. Starches are complex carbohydrates that break down into simple sugars after the action of saliva on them in the mouth.
Such starchy foods include:
- White bread
- Potato chips
- Crackers
- French fries
- Pretzels
If these food particles get stuck in the teeth, they can cause bacterial action and decay.
Hard foods
Hard foods don’t cause decay directly but they can cause physical damage, like chipping or cracking. Be careful while eating:
- Hard candies
- Chewing ice
- Nuts
- Popcorn kernels
- Olive pits
It’s best to avoid biting down on these items or consume them carefully.
Dried fruits
Dried fruits are healthy snacks but they can be surprisingly damaging. They combine the sugar content from the fruit along with the sticky texture that can stick to the teeth, allowing bacteria to release acids and cause tooth decay. Common culprits are:
- Raisins
- Dried apricots
- Prunes
- Dried cranberries
If you enjoy eating dried fruits, don’t forget to rinse your mouth or brush your teeth afterwards.
Alcohol
Alcoholic drinks can damage your teeth in various ways. Many are acidic, like wine, or high in sugar, like cocktails. Saliva neutralizes acids and washes away food particles. Alcohol dries out the mouth, reducing the flow of saliva, causing indirect decay. Be mindful when you consume:
- Wine (red wine also stains the teeth)
- Sweet cocktails
- Beer (also contains fermentable carbohydrates)
If you drink alcohol, stay hydrated with water and maintain good oral hygiene.
Hidden culprits
Some foods that cause tooth decay but most people are not aware of the fact:
- Flavoured yogurt (high added sugar)
- Granola bars (sticky and sweet)
- Fruit juices (high in sugar, natural or added)
- Canned fruits (are kept in sugar syrup)
- Smoothies (if made with added sugar)
Remember to check labels for hidden sugars and opt for less processed alternatives.
The impact of eating habits
How you eat affects your teeth as much as what you eat. Frequent snacking, especially on sugary and starchy foods, can keep your teeth exposed to acids. Sipping sugary and/or acidic drinks throughout the day will also damage your teeth. You can minimize such damage by:
- Reducing snacking between meals
- Drinking water instead of sugary drinks
- If you do indulge, do so as part of a meal rather than as a standalone snack
- Use a straw to reduce sugar contact with teeth
Protective foods for teeth
While some foods can damage your teeth, some can also protect them. These include:
- Dairy products, like cheese and milk (high in calcium and phosphates)
- Crunchy fruits and vegetables (stimulate saliva production)
- Sugar free gum (stimulates flow of saliva)
- Green and black teas (suppress harmful bacteria)
Adding these foods to your diet can aid dental health and offset damage done by other foods.
Final thoughts
While some foods can potentially damage your teeth, you need not eliminate them entirely from your diet. The key to healthy teeth is moderation and good oral hygiene.
You can protect your teeth while enjoying foods and drinks you love by:
- Limiting consumption of sweet and starchy foods and drinks
- Rinsing your mouth with water after eating potentially harmful foods
- Waiting for about 30 minutes after consuming acidic foods (else you may end up brushing softened enamel away)
- Using a straw to drink acidic or sugary drinks
- Maintaining good oral hygiene by brushing twice daily and flossing
- Visiting your dentist regularly for checkups and cleanings
Remember that a balanced diet is vital to good overall and oral health. Being aware of what can affect your dental health and taking the right precautions can help you enjoy a variety of foods while keeping your smile bright and healthy.
If you are concerned about your diet’s impact on dental health, discuss it with your dentist. They can provide personalized advice based on your individual needs and the state of your oral health.
