What is a sore of the mouth?
The sore: a painful ulceration
An oral sore is a painful ulceration, located in the mouth.
The occurrence of the sore is preceded by a sensation of cooking or burning.
A painful red spot appears and very quickly an ulceration forms.
The ulceration measures 2 to 10 mm, it is rounded or oval in shape.
It has a yellowish or greyish background with a clear and red edge.
The sore does not bleed, but it is painful especially during meals or when brushing teeth.
Most often the sore is unique but there may be several (up to 6) during a thrust.
In the mouth, canker can be present on all mucous and mobile areas of the mouth:
- On the edges, the underside or the tip of the tongue,
- Inside the lips and cheeks,
- On the floor of the mouth (under the tongue).
The gums attached to the bone, the hard palate and the dry side of the lips are spared by the canker.
The scarring is spontaneous: the sore loses its regularity, its limits become imprecise and the healing takes place in 10 to 15 days without scarring.
Canker are common and are not contagious
Canker occur outside of an infection context and are therefore not contagious.
They do not pass from person to person when kissing, sharing glass or cutlery.
Canker are very common ailments. Most people will have at least one sore during their lifetime.
