(FOX NEWS) - If you sleep with your mouth open, you may be at a higher risk of dental erosion and tooth decay.
An international team of researchers fitted volunteers with a device that continuously measured the pH levels and temperatures. At different stages of the night, the pH levels of mouth-breathers fell below the threshold when tooth enamel breaks down.
Previous studies have suggested individuals suffering with dry mouth have a higher risk of tooth erosion.
This is the first to study to continuously monitor pH changes in healthy individuals.
