A canker sore on tongue and sore throat typically refers to painful mouth ulcers accompanied by throat discomfort, often caused by minor injuries, stress, or dietary triggers. These sores, known as aphthous ulcers, appear as small, white or yellowish lesions with a red border.
Canker sores form when the thin tissue inside your mouth is damaged, leading to inflammation. The exact cause remains unclear, but factors like stress, minor injuries from sharp foods, acidic or spicy foods, and even certain vitamins deficiencies may contribute. Unlike cold sores, canker sores aren't contagious and don't result from a viral infection.
| Type | Size | Duration |
|---|---|---|
| Minor | Less than 1/3 inch | 1-2 weeks |
| Major | Larger than 1/3 inch | Several weeks |
| Herpetiform | Pinpoint-sized clusters | 1-2 weeks |
Many people confuse canker sores with cold sores. Cold sores are caused by the herpes simplex virus and appear as blisters around the lips. Canker sores, however, develop inside the mouth and are not contagious., while canker sores can be uncomfortable, they do not usually indicate a serious health issue.
Most canker sores heal on their own within a week or two. However, if you experience unusually large sores, persistent pain, or frequent outbreaks, consult a healthcare provider. Severe cases may require medical treatment to prevent infection or address underlying conditions.
I once had a canker sore that lasted nearly three weeks. After ruling out common triggers, my doctor suggested a vitamin deficiency. A simple adjustment in my diet helped speed up the healing process.
