Hi @GordonA 
Welcome to the forum and thanks for your message. I am sorry to hear about your teeth chatting, that sounds really frustrating for you.
I am sure others on the forum will let you know if they’ve had similar experiences and what may have helped them, but if you’d like further advice feel free to call the Parkinson’s UK helpline on 0808 800 0303. The helpline is a free service open Monday-Friday, 9am-7pm made up of trained advisers, including Parkinson’s nurses who will be able to give you further information and support so do give them a call.
Best wishes,
Emily - Forum moderation team
