aphtha, canker sore or oral ulcer?

[*Vi*]

Hi Guys,

Which one is better, aphtha, canker sore or oral ulcer? Which one is British/American? Is there any difference among them?

Thanks in advance.

Canker sore is what AmE laymen call it.

Hi Vi

Canker sore I have heard some Brits use whether this disputes the AmE or not, not sure. But some Americanisation has occured this side of the pond ; )

Oral ulcer would be used by the layperson in the UK, but more people would simply state:

"I have an ulcer in my mouth/gob/mush."

As for being more formal, then usage of Oral Ulcer would be heard.

As for apthna, quite scientific, so probably more in medicine. But your General Practitioner shouldn´t really use it, as the patient would be a bit confuggled (confused).
