Do i need a doctor or a dentist?

i don't have any dental insurance. but today part of my mouth and jaw started to hurt. it feels tight only in one very small area just slightly to the left of my my mouth from the middle and all the way day to my chin. i'm been doing some home remedies such as warm salt water. taking ibuprofen , using hydrogen peroxide. and i'm currently trying that pulling oil treatment and i am using coconut oil. it doesn't hurt to eat or to drink just when i touch it from outside of my mouth. i have no idea what it i have or if it can even be treated at home but i would prefer to treat it at home then go to the hospital or dentist
