Other than aesthetic purposes, Botox has several other benefits. One of them is that it can help lessen the aching of your jaw by stopping you from grinding your teeth. It can be a great tool to help alleviate pain from grinding your teeth as it will help relax the muscles that are in pain. In this case, it relaxes the masseter muscle and prevents it from overworking. When you grind your teeth, you may also notice your jawline starting to look wider, and it’s because you are building up those masseter muscles. Botox or Xeomin helps to lessen the appearance of this muscle—almost deflating it—so in addition to alleviating the clenching, it also slims your jawline. A great cosmetic bonus!
