The Link: How Your Diet Affects Your Teeth

Do you know how your diet affects your teeth? We often hear about the importance of eating healthy, but we don’t always consider what it means for our oral health.

Studies have shown that modern diets are leading to an increase in physical degeneration and dental problems – a trend started by nutrition pioneer Weston Price over 80 years ago.

In this blog post, we’ll discuss how nutrition and teeth interact, including the role of sugar in tooth decay and the impact of processed foods on oral health.

Plus, get tips for improving your diet for better oral health so you can protect those pearly whites.

Nutrition and Oral Health: How Your Diet Affects Your Teeth

Good oral health is essential for overall well-being, and nutrition plays a major role in keeping your teeth healthy. The research of Dr. Weston Price has shown that modern diets are linked to physical degeneration, including dental issues such as tooth decay and gum disease.

Price’s research detailed the core differences between what he called “traditional diets” and “modern diets.”

Traditional diets, as studied by Weston Price, are characterized by the following:

  1. Nutrient-dense: Traditional diets are rich in nutrients from whole, unprocessed foods, such as fresh fruits and vegetables, whole grains, and animal products.
  2. High in traditional fats: Traditional diets are high in traditional fats, such as animal fats and dairy products, which provide essential nutrients for good health.
  3. Minimal processed foods: Traditional diets are low in processed foods and contain minimal refined sugars and artificial additives.
  4. Culturally diverse: Traditional diets are culturally diverse and vary depending on the region, season, and available food sources.

Modern diets, on the other hand, are characterized by the following:

  1. Nutrient-poor: Modern diets are often low in nutrients, especially vitamins and minerals, due to the processing and refining of foods.
  2. Low in traditional fats: Modern diets are often low in traditional fats, such as animal fats and dairy products, due to concerns about cholesterol and heart disease.
  3. High in processed foods: Modern diets are often high in processed foods, refined sugars, and artificial additives, which can have a negative impact on health.
  4. Uniform: Modern diets are often uniform and standardized across different cultures, with a focus on convenience and fast food.

I find this research fascinating – particularly in three core areas…


Sugar is one of the biggest culprits when it comes to tooth decay.

Bacteria in the mouth feed on sugar and produce acid which erodes enamel, leading to cavities and other dental problems.

It’s important to limit sugary foods and drinks like candy, soda, cookies, cakes, etc., as much as possible if you want healthy teeth.

Whole Foods

Eating whole foods like fruits and vegetables can help keep your teeth strong by providing vitamins A & C which promote saliva production that helps wash away bacteria from the mouth naturally.

Whole grains provide fiber which also helps clean plaque off the surface of your teeth while dairy products contain calcium which strengthens bones including those in your jawbone that support your teeth structure.

Processed Foods

Processed foods often contain added sugars or artificial sweeteners, unhealthy fats, and preservatives which can all contribute to poor oral health over time due to their high acidic content or lack of nutritional value needed for proper maintenance.

Additionally, they may be difficult for some people to chew properly resulting in improper digestion that can cause further damage down the line. As we discuss often here at the Wellness Watchdog, it’s best to just avoid processed foods altogether.

Making healthy food choices is essential for maintaining good oral health.

Next, we’ll do a deeper dive into the role of sugar in tooth decay and how to make smarter dietary decisions to protect your teeth.

The Role of Sugar in Tooth Decay

Sugar is a major contributor to tooth decay.

When bacteria in the mouth break down sugar, they produce acids that can damage the enamel of teeth and cause cavities.

The more sugar you consume, the higher your risk for developing tooth decay.

Bacteria feed on sugars found in food and drinks such as candy, soda, fruit juice, cake, cookies, and other sweets.

As these bacteria break down the sugar molecules into smaller particles called monosaccharides (glucose and fructose), they also release acid which causes demineralization of dental enamel leading to cavities or caries.

The longer sugary foods remain in contact with teeth, the greater their potential for causing harm.

For example, eating hard candy takes longer to dissolve than drinking a glass of soda so it has more time to increase acid levels in your mouth which leads to increased risk of tooth decay over time.

Frequent snacking throughout the day is another factor that increases risk for cavities.

This is because there’s less opportunity for saliva production to help neutralize acidic environments caused by bacterial breakdown of sugars from food particles left behind after meals or snacks.

If you often snack on sugary foods like candy or cake, then your teeth are constantly exposed to high levels of acidity.

Bacteria break down these sugars over time, and saliva production during the digestion process doesn’t help reduce pH levels or tooth decay risks.

The amount of sugar we consume is important but so is when we eat it.

Limiting the sweet stuff between meals will help reduce our chances of getting cavities since there won’t be as much opportunity for bacterial activity on our teeth surfaces.

Sugar is a major contributor to tooth decay, but there are many other factors that play a role.

Eating whole foods as part of an overall healthy diet can help protect your teeth from decay and promote oral health.

Main Takeaway: Sugar consumption can lead to cavities, so it is important to limit sugary snacks and beverages between meals. Eating hard candy takes longer to dissolve than drinking a glass of soda, increasing acid levels in your mouth over time and the risk for tooth decay. Frequent snacking also increases this risk.

The Benefits of Eating Whole Foods for Healthy Teeth

When it comes to oral health, the foods we eat can have a major impact.

Eating whole foods such as fruits, vegetables, nuts, and seeds can help keep teeth strong and healthy.

These nutrient-rich foods are packed with vitamins and minerals that promote good dental hygiene.


Fruits like apples, oranges and pears contain high levels of vitamin C which helps protect against gum disease by reducing inflammation in the gums.

They also contain fiber which stimulates saliva production to naturally cleanse the mouth of bacteria that cause cavities.


Vegetables are another great source of nutrients for healthy teeth.

Leafy greens like spinach, kale and Swiss chard provide calcium for stronger enamel while crunchy veggies like carrots act as natural toothbrushes when eaten raw.

Cruciferous vegetables such as broccoli are also beneficial because they’re rich in antioxidants that reduce plaque buildup on teeth surfaces.

Nuts & Seeds

Nuts and seeds offer an array of essential vitamins including magnesium, phosphorus and zinc which all play a role in strengthening tooth enamel making them less susceptible to decay from acid erosion or bacterial infection.

Almonds are especially helpful because they contain protein compounds called histones which inhibit bacteria growth within the mouth cavity helping prevent bad breath caused by oral bacteria overgrowth known as halitosis.

In addition to their nutritional benefits, eating whole foods is important for overall health as well.

Fruits and vegetables provide dietary fiber necessary for proper digestion while nuts supply healthy fats that our bodies need to function optimally, making them an ideal snack choice throughout the day or added into meals whenever possible.

Eating whole foods that are rich in nutrients can help to keep your teeth and gums healthy.

However, it’s important to be aware of the potential effects that processed foods can have on your oral health as well.

Main Takeaway: Eating whole foods like fruits, vegetables, nuts and seeds can help keep teeth strong and healthy by providing essential vitamins and minerals for stronger enamel. These nutrient-rich foods also reduce inflammation in the gums, stimulate saliva production to cleanse the mouth of bacteria, provide dietary fiber for digestion, and supply healthy fats for overall health.

The Impact of Processed Foods on Oral Health

Processed foods are often high in sugar, which can lead to tooth decay.

The bacteria that live in the mouth feed on sugars and produce acids as a byproduct, which can erode enamel and cause cavities.

Additionally, processed foods are typically low in essential nutrients like calcium and phosphorus that help strengthen teeth.

Furthermore, some processed foods contain additives such as artificial colors or preservatives that may increase inflammation in the mouth and worsen existing oral health problems.

Sugar is one of the most common ingredients found in processed food products.

From breakfast cereals to canned soups to pre-packaged snacks, many convenience items contain added sugars for flavor enhancement.

Unfortunately, these extra sweeteners provide fuel for bacteria living inside the mouth and can quickly lead to dental caries if not properly managed with regular brushing and flossing habits.

Nutrition is also a critical factor in preserving healthy teeth and gums.

Processed foods are often lacking essential vitamins such as Vitamin D or minerals like calcium, which are vital for protecting teeth from acid erosion caused by sugary substances or other environmental factors like smoking cigarettes or drinking alcohol over time.

Without proper care of your oral hygiene routine, this could lead to more serious issues such as gum disease and periodontitis.

Finally, certain additives used during processing may further exacerbate existing oral health conditions such as gingivitis or periodontal disease due to their inflammatory properties.

For example, tartrazine, an artificial yellow dye commonly used for coloring everything from Doritos to Gatorade, has been linked with increased levels of plaque buildup around the gum line.

Similarly, sulfites present in some canned goods have been associated with irritation within soft tissues located near tooth roots.

Therefore, it is important for individuals who suffer from chronic dental issues related to inflammation to seek out natural alternatives whenever possible instead of relying heavily on processed food items containing potentially harmful additives.

Processed foods can have a detrimental effect on oral health, leading to cavities and other dental issues.

By making small changes in your diet, you can improve your oral health and keep your teeth healthy for years to come.

Tips for Improving Your Diet for Better Oral Health

Here are some tips to get you started:

Reduce Sugar Intake

Eating too much sugar can cause tooth decay, so reducing your intake of sugary foods and drinks is a great way to improve your oral health.

Try replacing sugary snacks with healthier options like fruits or vegetables.

You should also avoid eating candy and other sweets between meals as this increases the risk of cavities.

Increase Consumption of Whole Foods

Whole foods such as fruits, vegetables, nuts, seeds, legumes, and whole grains are packed with vitamins and minerals that are essential for good oral health.

These foods also contain fiber which helps keep teeth clean by removing plaque from the surface of the teeth.

Aim to include more whole foods in your diet each day for better dental hygiene.

Avoid Processed Foods

Processed food often contains added sugars which can increase the risk of tooth decay if consumed in excess.

Additionally, processed food tends to be low in nutrients that support healthy gums and teeth such as calcium and vitamin D.

To ensure optimal dental hygiene try limiting processed food consumption whenever possible or opt for healthier alternatives instead such as lean proteins or complex carbohydrates like quinoa or brown rice.

Drink Plenty Of Water

Drinking plenty of water throughout the day helps flush away bacteria that can lead to cavities while keeping saliva levels balanced which helps prevent dry mouth syndrome (xerostomia).

Saliva plays an important role in protecting against tooth decay by washing away food particles from our mouths after we eat so make sure you stay hydrated.

Main Takeaway: Eating a balanced diet that is low in sugar and processed foods, while including plenty of whole foods and water can help improve your oral health by reducing the risk of tooth decay. Make sure to include more fruits, vegetables, nuts, seeds, legumes, whole grains and drink lots of water throughout the day.
