While brushing my teeth, i noticed 4 red spots on the roof of my mouth near the back near my throat. what could they be?

Possibilities: Several possible causes include infection (bacterial or viral), cancer, allergies, or injury. It is impossible to know without examining the spots. You need to have a dentist examine the roof of your mouth to determine what the spots are, so see your dentist.

Spots: Sounds like traumatic areas, many possible causes, how long they been there, .

Many possibilities &: There is no way to know without actually examining you. It could be something benign and temporary and go away within a few days or something more serious in need of treatment. Merely giving you a list of possibilities isn't very helpful. If you want to know for sure, see your dentist. Regardless, any lesion that remains longer than 2 weeks needs to be diagnosed!

Please see a Dentist as soon as possible. If you have an infection in your tooth it can spread and be dangerous to your health and well-being.
