Loose teeth can be saved in a few ways. The first is to have them fixed as soon as possible. If the tooth is loose, it can easily fall out and become a problem. Secondly, you can use a dental dam to keep the tooth in place while you eat or drink. A dental dam is a thin piece of plastic or cloth that is placed over the top of your teeth when you are eating or drinking so that the food or drink doesn't go into your mouth.
