You may be rubbing your tongue against you teeth similar to people biting their nails. It looks like hyperkeratotic tissue (callous) that may be high risk to become pre-cancerous. Get it checked if it is not resolved within 2 weeks.
Thank you for replying. Yes I feel like my back two teeths are running against me. Can they shape down my teeths . What would the dentist do this spot? I have horrible anxiety.
Let me explain to you. Thickened skin/callous/hyperkeratotic tissue can go away if it is not irritated. Have your dentist follow up. I cannot predict all the sources of irritation on the area.
