1. Understanding Mouth Ulcers: An Overview

Mouth ulcers, medically termed aphthous ulcers, are small, painful lesions that develop inside the mouth. These ulcers are not contagious but can cause significant discomfort, making eating, drinking, and even speaking difficult. Understanding what mouth ulcers are and what differentiates them from other oral conditions is the first step in effectively managing them.

1.1. What Are Mouth Ulcers?

Mouth ulcers are typically small, round or oval-shaped sores with a white or yellowish center and a red border. They can appear on the inside of the cheeks, lips, tongue, or the floor of the mouth. Unlike cold sores, which are caused by the herpes simplex virus and appear on the outside of the mouth, mouth ulcers are not caused by a virus and are not contagious.

1.2. Types of Mouth Ulcers

There are three main types of mouth ulcers: minor, major, and herpetiform.

Minor Ulcers: These are the most common type, accounting for about 80% of all mouth ulcers. They are typically small (less than 1 cm in diameter), heal within one to two weeks without scarring, and are usually not intensely painful.
Major Ulcers: These ulcers are larger (more than 1 cm in diameter), deeper, and more painful than minor ulcers. They can take several weeks to heal and may leave scars. Major ulcers are less common, affecting about 10% of those who experience mouth ulcers.
Herpetiform Ulcers: Despite their name, herpetiform ulcers are not caused by the herpes virus. They appear as multiple, small, pinpoint-sized ulcers that cluster together. These ulcers can be quite painful and usually heal within one to two weeks.

1.3. Differentiating Mouth Ulcers from Cold Sores

It’s crucial to distinguish mouth ulcers from cold sores, as they have different causes and require different treatments. Here’s a comparison:

Feature	Mouth Ulcers (Aphthous Ulcers)	Cold Sores (Herpes Simplex)
Location	Inside the mouth	Outside the mouth (lips)
Cause	Not viral, various triggers	Herpes simplex virus (HSV-1)
Contagious	No	Yes
Appearance	White or yellow center, red border	Blisters that crust over
Pain	Usually painful	Tingling, burning, then painful
Healing Time	1-3 weeks	1-2 weeks
