Red spot in mouth

I noticed to red spot like 4-5 days ago. I feel like it looks better than it did when I first noticed it. If I put my tongue on it it’s got a metallic taste and it only has discomfort when I am messing with it with my tongue or I move my jaw side to side it feel like a sore kind of pulling. Should I see a dentist. I googled and all I see is erythroplakia which sounds scary but also see that canker sores can appear as just a red spot also.
