If thrush is mild, it will usually heal without any measures, but if it is severe probiotics are only an adjunctive treatment. The disease can heal itself in mild cases, but in severe cases it doesn’t do much. Thrush is a disease of white sores in the mouth caused mainly by bacteria. Taking probiotics is only an aid, if the disease improves while taking probiotics, the symptoms are only mild. Severe thrush requires antibiotics to suppress the bacteria and thereby suppress the disease, while probiotics can be taken as an adjunct to this treatment. Probiotics do not treat thrush alone, and patients can also rinse their affected areas with salt water while taking the medication, which is more effective when taken internally and used externally. Inhibiting bacteria is the main treatment for thrush, and both medication and rinsing are designed to inhibit bacteria. You can take some probiotics when treating thrush, but it should not be the main treatment. If you don’t want to take medication, you can start with physical therapy to suppress the bacteria. If the physical approach does not work then medication is the only option.
