Good to know your dream and one more page is added to your dairy and in my opinion the focus of your dream is on relationships, teeth and dentist, so in my opinion your dream is telling about the relationships and secondly as you said you wanted to speak but you can't so possibly it means you want to express something but you are not expressing it due to any factors.

Thanks for sharing this dream with us and wishing you an great day. Stay blessed. 🙂
