While scientists are still trying to figure out what causes salivary gland stones, there is a list of common risk factors that may increase your chances for developing this condition. These include:
Dehydration
Smoking
Poor diet
Certain medications
Gum disease
Trauma to the mouth
‍The most significant being dehydration and smoking cigarettes or cigars constantly; also make sure you eat well-hydrated food such as applesauce with lunch every day! If it's not already present in our bodies - gum disease can lead us down the path towards becoming sick with sialolithiasis too (though rare). And lastly trauma could trigger an infection at any time so keep those smiles looked after by visiting the dentist often.
