Your gums are incredibly important. They help to provide you with a beautiful, confident smile. However, this is not their only role. The gums are also crucial for your oral health as well. Healthy gums provide a tight, protective seal around the necks of your teeth. This seal keeps bacteria and other debris from falling below the gum line, preventing them from attacking your periodontal ligaments and jawbone. They cover the sensitive roots of your teeth, preventing tooth sensitivity. They also play a role, in conjunction with your jawbone and periodontal ligaments, in keeping your teeth stable and in proper alignment.
