Hi everyone!

I'm 29 years old and a non smoker. Mommy to a beautiful 2 year old who still nurses due to rare food allergies. Of course all things that scare me medically happen on the weekend. While I was brushing my teeth last night I noticed a white/yellowish bump on the side of my tongue. It's painless and I have no clue how long it's been there. Definitely not an ulcer, I've had those and know how painful they can be!! I'd love any advice on who to see. I have a union dentist who I don't really trust knowledge wise.. Should I see an ENT, Oral Surgeon or who??

I attached some pictures - any advice would be appreciated!! I'm freaking out The picture is the same bump but all different angles. I'm scared it could be cancer..
