Acid reflux disease, also known as GERD, is quite common among adults. It is the reflux of stomach acids back up into the esophagus, which can make its way into the mouth. When the acid comes in contact with teeth, it can demineralize them. 
Typically, enamel on the tongue and palate surfaces of the teeth is affected the most, rather than the cheek side of the tooth. Acid reflux can also cause dry mouth, aiding the growth of bacteria and plaque, which increases the risk of developing cavities. 
Other symptoms of acid reflux disease include bad breath, sore throat, heartburn, and a bad taste. Molars are usually the most affected, due to their proximity to the esophagus, so the signs of enamel loss may not be noticeable without inspection by your dentist.
If you know that you have acid reflux disease, or are experiencing any of the symptoms outlined above, make sure to contact your dentist. If you have any questions, feel free to contact us here at the Rideau Dental Centre by calling 613-230-7475.
