I need a corrective bit that would quiet his head while riding.
No bit is going to "fix" a horse who is resisting. You need to rule out the many reasons why he might be tossing his head.
I agree that the teeth being checked is the first step. Do they need to be floated?
Get a bit that fits. A sloppy fitting bit can hurt, which would cause major resistance.
Then, if the teeth are OK, I would take a good look at the type of contact you are giving him. Inconsistent contact or contact that is not backed up by the leg will create resistance.
If you could post some videos of your riding, we could give an idea of where the resistance might be coming from.
