Hi,

I have dentures and some severe bone loss in my jaw, upper and lower, TMJ problems, sinus problems.
My question is: When I chew, the noise in my head is almost deafening. It really bothers me, and is so loud that I can't really focus on anything else.
Is this normal for dentures?
Thank you.

I don't think so. Mine don't do that. Are they loose? Maybe you need an alignment? What about your TMJ? Does it cause noise?
