Can Fasting Help with Teeth Decay?

Teeth decay can stem from a variety of factors, including daily habits like drinking your morning coffee and neglecting proper oral hygiene. While it may feel impossible, its progression can be slowed with adequate oral care. It is widely known that fasting offers numerous health benefits, but can it also help with tooth decay? Is it possible to reverse tooth decay through fasting alone? 

Let’s explore how fasting might impact your dental health and whether it can play a role in preventing tooth decay.

What Causes Teeth to Decay Rapidly?

A poor diet and certain lifestyle factors contribute to tooth decay, including the formation of cavities and the erosion of tooth enamel. Teeth decay can result from various causes, including:

• Bacteria that accumulate in the mouth throughout the day.

• Sugary and acidic foods and drinks.

• Plaque buildup caused by inadequate or lack of brushing and flossing.

• Poor oral hygiene, such as neglecting to brush teeth twice a day as recommended.

Can Fasting Help Prevent Teeth Decay?

Fasting cannot get rid of tooth decay, however, it can help prevent further decay. Fasting not only supports better health by aiding with weight management and reducing the risk of heart disease, but it can also improve oral hygiene habits and encourage healthier dietary choices.

Here’s how fasting can help prevent teeth decay:

• Enamel preservation: Fasting can help prevent tooth enamel erosion by reducing the frequency of acid exposure from food and acid production in the mouth, as fewer meals are consumed throughout the day. 

• Diminishes plaque buildup: Fewer eating occasions reduce the exposure of food particles and sugar lingering on teeth and the mouth, resulting in less plaque accumulation.  

• Reduction of bacterial growth: Decreasing meal frequency limits the availability of sugars and carbohydrates that bacteria feed on, reducing bad breath and minimizing the risk of cavities and gum inflammation (gingivitis).

How Fasting May Support Oral Health

Fasting not only promotes a better lifestyle and eating habits, it can also reinforce oral health in multiple ways.

Supports gum health by reducing inflammation

Fasting helps reduce inflammation markers in the body, significantly benefiting gum health. By lowering inflammation, fasting may reduce the risk of gum disease. Moreover, it can promote faster healing after dental procedures such as cleanings or extractions, as the body’s reduced inflammatory response supports quicker tissue repair. 

Improves tooth sensitivity over time

Reducing sugar intake through both fasting and improved dietary choices can lower overall sugar and acid consumption. The absence of sugar and acids from a fasting-friendly diet helps desensitize the teeth over time, allowing tooth enamel to strengthen and regenerate, further reducing tooth discomfort.

Promotes tooth enamel remineralization

Increased liquid consumption during fasting promotes saliva production and flow, which helps cleanse the mouth by washing away food particles. Additionally, saliva is rich in minerals like calcium and phosphate, which aid in the remineralization of tooth enamel, helping repair early signs of decay. 

Strengthens the immune system helping prevent infections

Fasting can boost the immune system by triggering adaptive responses in cells, making them more resilient to future stressors. When fasting induces mild stress, it prompts cells to activate protective mechanisms, strengthening immune function. A stronger immune system helps prevent oral infections.

Reduces the risk of dry mouth and bad breath

Fasting can help prevent dry mouth by stimulating saliva production by promoting hydration. Proper hydration is crucial during fasting to support energy levels, maintain bodily functions, and ease hunger pangs. Consistent liquid intake supports healthy saliva production, keeping the mouth moist and helping to prevent dry mouth and bad breath during fasting.

Potential Risks of Fasting and Teeth Decay

Fasting comes with its own risks; while it does not directly cause tooth decay, it can encourage habits that contribute to it. 

Potential dehydration can reduce saliva production

Fasting entails modifying your eating routine, meaning it might impact regular liquid consumption habits. Additionally, eating only during fasting windows reduces food consumption, which also limits the intake of food that serves as a water source for the body. A dry mouth results from reduced saliva production, which impacts the natural cleaning of the mouth, weakens the remineralization of tooth enamel, increases bacterial growth, and raises the risk of developing cavities. Due to this, proper hydration habits are vital during fasting, not only to ensure optimal bodily functioning but also to maintain prime oral health. 

Stress and teeth grinding

Fasting can be a source of stress for some individuals, particularly if it disrupts their routine or causes physical discomfort, such as cravings or irritability. This stress may manifest as teeth grinding or clenching, a condition known as bruxism. Grinding wears down tooth enamel, making it more vulnerable to sensitivity, fractures, and decay. To mitigate these risks, manage stress during fasting through stress-relieving techniques such as meditation, reading, yoga, or swimming.

Best Practices for Supporting Teeth Health During Fasting

Ensure your oral health remains in good condition by following these tips.

• Optimal hydration: Drink plenty of water during fasting to avoid dry mouth and its side effects. Set specific water intake objectives to ensure healthy hydration. Learn more about fasting-friendly beverages. 

• Good oral hygiene: Follow a consistent oral hygiene routine with regular brushing, flossing, and using fluoride toothpaste.

• Proper care after eating certain foods: Stay away from sugary and acidic foods. Drinks with a specific pH tend to erode and soften the enamel surface. After consuming acidic foods or drinks, such as plain black coffee or citrus fruits, rinse your mouth with water and wait at least 30 minutes before brushing your teeth, this helps prevent tooth enamel erosion.
