In healthy individuals, a small amount of liquid or gas reflux can occur after meals and during the first three hours afterward. This type of reflux is usually mild, slightly acidic, brief, and often barely noticeable.
When reflux becomes more frequent and is accompanied by symptoms, it is referred to as gastroesophageal reflux disease (GERD).
Gastroesophageal Reflux: When Does It Occur?
When reflux progresses to disease, it can permanently damage the teeth. The material that flows back into the esophagus is largely composed of hydrochloric acid – one of the most corrosive and irritating acids (pH 1).
Consequences of Gastroesophageal Reflux
Chronic GERD patients often have teeth that appear gray-yellow-brown due to irreversible enamel loss. The tooth color changes because acid erosion from the stomach dissolves the enamel, exposing the dentin underneath, which is naturally yellowish and less translucent.
Beyond aesthetic concerns, exposed dentin causes dentin hypersensitivity to thermal stimuli (hot and cold). The acidic environment also significantly increases the risk of cavities.
A Remedy for Gastroesophageal Reflux
Because the refluxed material is highly acidic, it is recommended to increase the dosage of Cariex® (6/7 sprays) and to swallow the saliva along with the excess product. This allows the bicarbonate’s buffering effect to also act on the mucous membranes of the throat and esophagus, providing immediate relief and eliminating the burning sensation.
