Sensitive teeth
When the teeth are constantly pressed up against each other in a misaligned manner, or if you are clenching or grinding your them in your sleep, your teeth can become worn or cracked. While your teeth are naturally strong, they cannot withstand constant grinding and clenching. Worn enamel cause sensitivity in the teeth, making hot or cold foods and beverages difficult to ingest. While special toothpastes and mouth washes can help to treat sensitive teeth, once the enamel is gone, there is no replacing it, so it is imperative to seek treatment for sensitive teeth at the first sign.
