Aphthous ulcers typically resolve within approximately 3 to 7 days; however, the exact duration depends on individual circumstances and requires comprehensive assessment. If treated promptly under a physician’s guidance with appropriate use of oral ulcer powder, healing may occur in about three days. Conversely, if medications are not used as prescribed, resolution may take up to seven days. Patients are advised to protect the ulcerated area carefully in daily life.
