  • Dentures that do not fit well and are brushing against the soft skin inside your mouth can cause canker.
  • Orthodontic brackets and bands can also hurt the soft tissues in the mouth with regular friction. It could also cause canker – in fact, canker is quite common in the initial days of orthodontic treatments when your mouth is still getting accustomed to the orthodontic attachments.
  • Broken tooth with a sharp edge can hurt the sensitive skin inside your mouth and cause mouth sores where it touches the skin.
