16. Bruxing Sideways: Effect on Canine/Molars

  • Grinding of cuspid (canine) developing to back tooth wear, recession and abfraction

Purposes

  • Show that canine bruxing breaks down anterior guidance, leading to problems with molars including recession, looseness, wear, cracks and abfractions.
  • Illustrate that the recessions and abfractions we see at gum lines are not only from brushing teeth too hard but from flexure and repeated bending.

bruxing sideways

Presenting

  • State how the front teeth have longer roots in general than the back teeth, and experience smaller forces as they are further from the fulcrum.
  • Explain that possibly when searching for a centric bite, nervous habits, or stress, we can also wear down our front teeth - shown in an accelerated manner in this animation.
  • When the front teeth wear down, anterior guidance is lost.
  • Back teeth can now experience sideways forces that they do not bear well, so they are loosened.
  • Teeth can also bend slightly by these forces causing abfractions where the hard enamel of the crown meets the softer cementum of the root.
  • Photos illustrate how abfractions can also occur in the front teeth when they are experiencing bruxing.
