Feel like i have canker sores down the back of my throat. what can i do to get rid of them?

Canker sores: Canker sores most of the time go away without any treatment. Avoid hot or spicy food, mouth washes with salt water or a mild mouth wash if you get recurrent canker sores you may have an underlying nutritional deficiency and need to be investigated and treated for that.

Canker sore relief: Consult with your dentist now so he can see the lesions. He may prescribe a mouth wash to sooth the tissue while you wait for the healing. It usually runs its course in 7-10 days. He will make a diagnosis from further information you give him on the history of these lesions.
