So I tried to open his mouth tonight. It's like wrestling a bear. I grabbed his head like more than a dozen times but he would twist and squirm and I felt like I was going to break his neck so I let go. I was able to open his mouth a tiny bit with a q tip but couldn't keep it open long enough to see the roof of his mouth. I saw a white spot on the roof of his mouth, but it could have just been the top of his mouth, I don't know. The bump has not gotten any bigger or smaller, and it's hard to the touch. Any suggestions? It doesn't seem to bother his eating etc. But I'm still worried
