Not to forget:
Tetracycline can cause yellow staining of teeth, thus, never given to children less than eight years of age. However, Rocky Mountain spotted fever (RMSF) - named after Rocky Mountains in Colorado- is the only indication of giving Tetracycline in all age groups.
Rifampin can cause orange discoloration of teeth.

how do we get rid of external stains naturally?
There’s no natural solution to it. Firstly you need to get professional scaling treatment done and then find the external source that’s causing it and try to omit it.
