I have a sore on the bottom of my gum and these tiny lil red dots on the front of my tongue all burn depending on what I eat is it a infection?

Sore on gum. Without a visual exam, it is impossible to know for sure. It sounds like ulcers and/or canker sores. If so, they should heal on their own in 7-10 days. Avoid spicy foods. If they don't heal in a week, have them examined by your dentist.
