Severe acid reflux can cause a condition called erosion, where the acid dissolves the enamel (outer) layer of the tooth and expose the underlying structure of the tooth called dentin. This can lead to sensitivity, pain and even death of the tooth if not treated at right time.
Though tooth pastes and mouthwashes which contain fluoride, or sensitivity tooth pastes can give temporary relief, it is important that the damaged tooth is treated appropriately using a coverage (a filling or a cap), in order to make the tooth function well and to stop further damage.
Next Steps
Visit a dentist soon.
Health Tips
While your dentist takes care of the damaged teeth, make sure you visit a physician to get the acid reflux under control as it suggests a general health condition.
