The Surprising Connection Between Gut Health & Dental Health

The Surprising Connection Between Gut Health & Dental Health

When thinking about dental health, most people focus on brushing and flossing. But did you know that gut health can play a crucial role in maintaining a healthy mouth? This blog post from East Bentleigh Dental Group will detail the connection between gut health and dental health.

Acid Reflux

Acid reflux is a condition where stomach acids flow back into the oesophagus and sometimes into the mouth. This acid can erode tooth enamel, leading to increased tooth sensitivity, decay and other dental issues. Managing acid reflux through dietary changes, medications and lifestyle modifications can help protect your teeth from the damaging effects of stomach acids.

Oral Microbiome Balance

The mouth and gut share similar bacterial environments, and an imbalance in gut bacteria can disrupt this harmony. An overgrowth of harmful bacteria in the gut can lead to an increased presence of these bacteria in the mouth, causing issues like bad breath, gum disease and tooth decay. Maintaining a balanced gut microbiome can help to keep oral bacteria in check, contributing to overall dental health.

Immune System Function

A healthy gut is essential for a robust immune system. With a large portion of the body’s immune cells residing in the gut, any compromise here can weaken the body’s immune response. This makes it harder to combat oral infections and inflammation, leading to a higher risk of conditions like gingivitis and periodontitis. Supporting gut health with probiotics and a balanced diet may help to strengthen the immune system and aid in the prevention of oral diseases.

Nutrient Absorption

The gut is responsible for absorbing vital nutrients, including those important for dental health like calcium and vitamin D. Poor gut health can lead to malabsorption, resulting in deficiencies that may weaken teeth and increase susceptibility to cavities and gum disease. Maintaining a healthy gut promotes better nutrient absorption, which in turn supports stronger, healthier teeth.


Probiotics are beneficial bacteria that support gut health, but they can also positively impact oral health. Studies suggest that probiotics may reduce the levels of harmful bacteria in the mouth, helping to prevent cavities and gum disease. Incorporating probiotics into your diet through supplements or fermented foods can be an effective strategy for maintaining gut health and achieving an optimal bacterial balance in the mouth.
