When you first get your braces, you may notice that your teeth and mouth feel a little tender or sore. This is perfectly normal for patients who have just gotten their braces put on, and Dental Specialists of New York PC promise your mouth will not be sore forever! To relieve the pain, we recommend dissolving one teaspoon of salt in eight ounces of lukewarm water. Swish and gargle this solution in your mouth for just a couple of minutes (do not swallow the saltwater).
