Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have an ulcer over the lower labial
frenulum that is the mucosal fold connecting lower lip to gums and the ulcer can occur on it commonly due to trauma caused by brushing or any hard food or other causes..
It can also be a
canker sore..
Nothing to worry as the pain and ulcer will resolve gradually in a week time..
You can applya numbing gel containing Lignocaine over it..
You can also take anti inflammatory painkiller like
Ibuprofen..
Avoid spicy and hard foods..
Suck ice pops and do cool water rinses to reduce inflammation..
You can also take Ibuprofen to reduce inflammation and pain..
Maintain a good
oral hygiene and use antiseptic mouthwash to gargle.
In case of no improvement in a week consult an Oral Physician and get evaluated..
Hope this information helps..
Thanks and regards.
