over counter mouth ulcer

Common active ingredients listed in OTC mouth ulcer products include benzocaine, hydrogen peroxide, menthol, and docosanol. Some items also mention hyaluronan (hyaluronic acid) and vitamin B12.

OTC treatments often create a protective barrier over sores using film-forming gels or hydrocolloid patches. These products help shield the sore and keep medication in place.

Application methods include touch-free or control-tip applicators for direct dosing, quick-drying liquid solutions, swishing a capful of rinse for about a minute, and placing stick-on or dissolving melts next to the sore.

Patch or stick-on treatments are described to remain in place for hours; some listings specifically note adhesion to the gum for about 2–4 hours.

Rinses are described for temporary use and are typically used up to four times daily (for example, after meals and at bedtime) or as directed by a dentist or physician.

Common precautions include keeping products out of reach of children and obeying label age restrictions (e.g., ‘not for children under…’). Product labels may also list specific age minimums—always read and follow the packaging directions.
