A Detailed Description of Mouth Ulcer Appearance

A Detailed Description of Mouth Ulcer Appearance

Mouth ulcers have a distinctive appearance that helps distinguish them from other oral conditions. Here's a comprehensive description of what a typical mouth ulcer looks like:

Shape:

Usually round or oval

Well-defined borders

Can be singular or appear in clusters

Size:

Minor ulcers: Typically 2-8 mm in diameter

Major ulcers: Can be larger, sometimes exceeding 1 cm

Color:

Center: White, yellowish-white, or light gray

Border: Reddish or pinkish, often inflamed

Depth:

Minor ulcers are usually shallow

Major ulcers can be deeper and may have a crater-like appearance

Surface:

The center often appears slightly depressed compared to surrounding tissue

May have a shiny or glossy appearance due to the absence of normal mucosal texture

Surrounding Area:

The tissue immediately around the ulcer often appears red and inflamed

There may be slight swelling in the area

Location:

Can appear on the inside of the cheeks

On the tongue (sides or underneath)

Inside the lips

On the soft palate

On the floor of the mouth

Occasionally on the gums

Number:

Can occur as a single ulcer

Sometimes appear in groups, especially with herpetiform ulcers

Stages:

Early stage: May look like a small red spot or feel like a burning sensation

Developed stage: Full white/yellow center with red border

Healing stage: Gradually shrinks and becomes less white as it heals

Variations:

Herpetiform ulcers appear as clusters of very small ulcers that may merge

Some ulcers may have an irregular shape rather than being perfectly round

Contrast:

Stands out clearly against the pink background of healthy oral tissue

It's important to note that while this description covers typical mouth ulcers, appearances can vary. Some conditions, like oral cancer, can mimic the appearance of mouth ulcers. Therefore, any persistent or unusual oral lesions should be evaluated by a healthcare professional, especially if they don't heal within two weeks or are accompanied by other symptoms.
