Discussion: I have severe gingivitis with bleeding and also occasional toothache. The dentist prescribed me antibiotics, but I felt bad almost immediately. Is there a temporary replacement for antibiotics?

You can apply two drops of eucalyptus or grapefruit seed oil (both very bitter). In that case, you will feel almost immediate relief because of eucalyptus oil's antibacterial and antiviral properties. But this is a temporary solution, not a substitute for maintaining oral hygiene and dental care.
