Very small hard thing on roof of my mouth. feels like a grain of sand and wont go away. dr. or dentist?

Need Consultation: A dentist needs to see this to determine if this is simple or complex. Simple is easy to care for. Complex may be cancer. Get a consultation soon.

Needs to be seen: I would see your general dentist for a consultation. He\she can refer you to another type of doctor if necessary. It might be something simple, benign and easily remedied. If not, your dentist will discuss it with you.
