My dentist extracted my tooth yesterday and broke it off leaving one of the roots behind.He fished to get the root out for 20 mins then panicked and said lets leave it , its too close to the sinus.Today I have liquid every time i drink coming down my nasal passage,nostril.It feels as if he's actually damaged my sinus,I'm in much pain.I want the root out too ,but he's said it will heal over fine,won't get infected and is safe when I questioned this.Advice please?
