Is this a canker sore?

[emmachwe2025!]

Canker sore or cut below front bottom tooth. Painful. Started two days ago. What causes something like this in this location?

 

[Dr M]

Canker sores could be due to a host of factors, including stress, as well as a dip in your immune system, for example when you are sick with the flu. Treatment is only symptomatic and most canker sores disappear after about 10-14 days.

So it’s not particularly concerning in this location? And will heal in 10-14 days?

@Dr M is it unusual to have an ulcer in this spot? is this the attached gingiva?

 

[Dr M]

It looks like it is at the level of the muco-gingival junction. It is a common area for a canker sore to develop.
