Mouth Sores: When Should You Worry? | The Wonder Tooth Podcast

Almost everyone experiences a mouth sore at some point in life. Some disappear quickly and cause only mild irritation. Others become painful, persistent, or concerning enough to interfere with eating, speaking, and daily comfort.

Many patients ask:

“Is this just a canker sore, or should I be worried?”

The truth is that mouth sores can have many different causes. Some are harmless and temporary. Others may signal irritation, infection, immune responses, nutritional deficiencies, stress, or more serious health concerns.

Knowing when to seek professional evaluation matters.

In this episode of The Wonder Tooth Podcast, Dr. Radwa Saad explains common causes of mouth sores, warning signs to watch for, treatment approaches, and when oral lesions should never be ignored.
