Why grinding matters


Excess bite forces can chip fillings, crack crowns, loosen bridge cement, and overload implants.


Signs you might grind


Morning jaw soreness, headaches, flat/worn edges, chipped enamel, or fractured fillings.


Protection plan



  • Nightguard customized to your bite

  • Address stress, caffeine late in the day, and sleep posture

  • Regular bite checks and maintenance cleanings


FAQ


Will a nightguard stop grinding?


It protects teeth/restorations; habit reduction varies.


Do I need a special guard with implants?


We often recommend one—ask at your exam.


Can Invisalign trays act as a guard?


They offer some protection during treatment; retainers post-treatment may help, but ask about a dedicated guard.
