I just came across your blog, so I thought I'd take the opportunity to ask you a question. I just started wearing my permanent full upper denture. In your opinion, would it okay to use Colgate Total with Whitener to clean this appliance? (I use that on my remaining lower teeth.) It seems like most dental professionals advise against this, but I'd like to know whether or not you think there's a good possibility that the appliance could be damaged by this.
