After using sensodyne rapid relief my tongue tip especially is numb as if it’s burnt and slowly spreading to whole mouth and I can’t taste the sweet and saltiness of any food.

I started using this toothpaste about a week ago and I noticed that my tongue was is always burning. It also feels very dry like there is a coating on it. I did help the sensitive teeth, but honestly I would rather have my teeth hurt. It's very expensive too.
