As per the Green Shield Benefit brochures, if a dental claim is expected to exceed $500, it is strongly suggested that the dentist submit an estimate of the expenses to Green Shield prior to the dentist administering the procedure.  This will ensure that the procedure the dentist recommends is eligible for coverage.  

Dental coverage (excluding orthodontic services) has a maximum benefit of $1,500 per benefit year, per dependant.

Orthodontic coverage has a lifetime limit of $4,000 per dependant.

To discuss your specific claim with someone from Green Shield directly, you can contact them toll-free at 1-888-711-1119.
