It may seem like a stretch to think that something as seemingly innocuous as a toothache could lead to an upset stomach. Still, there is a very strong connection between dental and digestive health. Oral bacteria can travel to the digestive tract and cause inflammation when it enters the bloodstream. This inflammation can lead to several digestive problems, including diarrhoea, constipation, and nausea. In addition, tooth decay and gum disease can cause pain and sensitivity in the mouth, making it difficult to eat. As a result, poor dental health can indirectly cause various digestive issues. Therefore, it is crucial to see a dentist regularly in order to maintain good oral hygiene and avoid potential gut problems down the road.
