Canker Sores & Mouth Ulcers
Over the counter relief options

Having Canker sores or mouth ulcers?
Canker sores and mouth ulcers are small, painful lesions that develop inside the mouth, commonly on the inner cheeks, lips, tongue, or gums. They are not contagious but can make eating, drinking, and talking uncomfortable. Triggers may include stress, minor mouth injuries, acidic or spicy foods, vitamin deficiencies, hormonal changes, or irritation from dental products. Management focuses on reducing pain, protecting the sore while it heals, and preventing further irritation.
