What mouthwash should be used for oral ulcers?

Aphthous ulcers (canker sores) commonly occur on the inner surface of the lips, tongue, ventral surface of the tongue, buccal mucosa, vestibular groove, and soft palate—causing discomfort that disrupts sleep and eating, and impairs speech. They are a common ulcerative condition affecting the oral mucosa. So, what mouthwash should be used for aphthous ulcers? Below, we address this question.

What mouthwash should be used for aphthous ulcers?

Generally, patients with aphthous ulcers may use various antiseptic mouthwashes. Options include a 0.1% solution of rivanol, a 0.1% potassium permanganate solution, a 0.02% furacilin (nitrofurazone) solution, or a 3% compound boric acid solution.

Clinically, a 0.02% chlorhexidine gluconate solution or a 0.12% chlorhexidine gluconate solution may also be used. Additionally, a 2% tetracycline solution or a 0.25% chlortetracycline (aureomycin) solution may be effective. After using any of these mouthwashes, avoid rinsing with plain water, as this helps maximize therapeutic efficacy against aphthous ulcers.

Patients are advised to minimize intake of spicy and irritating foods and instead consume fresh vegetables and fruits rich in B-complex vitamins—such as carrots and kiwifruit. Maintaining good oral hygiene is also essential. Please note: The above recommendations are for informational purposes only.
