The gums, or gingiva, surround the base of the tooth, helping to protect it from damage and infection. The tooth is anchored into the jawbone by a root, which is covered in a layer of cementum. Finally, the outer layer of the tooth is made up of enamel, which is the hardest substance in the human body, even harder than bone.
