Home treatment for an ingrown toenail involves lifting up the affected corner of the nail and positioning a small piece of cotton between the skin and the nail, notes eMedicineHealth. Wash the affected foot four times daily, and change the cotton every day until the nail grows out.
A severe ingrown toenail requires treatment by a medical professional, advises Mayo Clinic. The doctor often trims or removes the ingrown part of the nail after numbing the affected toe. If the problem recurs, removing the nail and tissue using a laser or chemical treatments may be necessary. In either case, the doctor may recommend antibiotic treatment for the condition.
