Definitions

  • Bacillus mutans is one of the bacteria constituting plaque, and Bacillus mutans causes adverse effects such as increasing acidity of teeth, corroding teeth, and causing inflammation of gums. Plaque also prevents the calcium ions in the saliva that need to be restored to the damaged teeth from going to the teeth. Calcium ions that do not reach the teeth are absorbed by plaque and crystallize. After calcium absorption and crystallization, the plaque hardens and adheres to the teeth. this is tartar Although tartar blocks the outside of the enamel, it prevents chemical repair of the enamel surface by allowing acids to pass through and retaining calcium ions. The tartar made in this way makes it more difficult to remove plaque, and the vicious cycle is repeated.
