Does anyone know if there are regulations on how soon participants must be notified of plan changes to a non-contributory dental plan?

The usual erisa rules apply---I think 90 days after the year in which the change occurred.

I think the general ERISA rule is 210 days after the end of the plan year in which the change was adopted.

Keep in mind, though, that you are vulnerable to a participant lawsuit based on reliance on the SPD until you provide updated information. So, even though ERISA may give you lots of time, as a practical matter sooner is better.

Also, don't forget the 60 day rule for a summary of material reduction if your dental plan is subject to HIPAA.
