Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the discolouration of the gum around the stitches can be due to infection in the area and the gums in the area seems to have inflamed due to surgical trauma as well as infection..
Other thing is that the
plaque that you thought of was gum, that could have got detached and a small inflamed flap is appearing in the front part of mouth..
As the pain is extreme you should consult your treating
dentist and get evaluated and he can look for the exact cause of the pain and treat you accordingly..
In case if there is an infection, irrigation with antiseptic mouthwash and a prescription of antibiotics and anti inflammatory painkiller can be advised..
You can also be advised to apply numbing gel over painful area..
Do warm saline gargles..
An
x ray can also be taken to check for any remaining root pieces of teeth and can also be a cause of pain and needs removal..
Hope this information helps..
Thanks and regards.
