Prolonged enamel erosion can create microscopic channels through the enamel, exposing the sensitive dentin layer of the tooth. Common symptoms include a sharp pain or ache when you eat or drink something that is hot, cold, sweet or acidic.
Increased exposure to fluoride helps to restore the mineral density of your tooth enamel. This process is known as remineralization, and effectively counters enamel erosion.
Brushing your teeth with a specially formulated toothpaste designed to counter sensitivity symptoms can provide short term relief. However, the underlying problem will still persist.
If the doctor suspects your sensitivity issues are linked to enamel erosion he might recommend a treatment strategy that includes a concentrated fluoride treatment. This will likely be followed by daily prescription fluoride supplements, and using a brand of toothpaste with added fluoride to brush your teeth.
