I had a swollen retromolar trigone, that turned into what i would call an open sore. It does not bleed but does kill when trying to eat, also I cant open my mouth wide enough to eat anything, so its been difficult.  Should i be considered since its going on day 4?
Hi. Thanks for the query. I have gone through your query and can understand your concern. As per your complaint it seems an ulcer on retromolar trig one can be a Canker sore or can be an abscess caused due to infection. It can also be due to traumatic injury caused by some hard or sharp foods. I would suggest you to consult an Oral Physician and get evaluated. As of now take anti-inflammatory painkillers like Ibuprofen and apply numbing gel containing Lidocaine over it especially before eating to ease in eating. Do cool water rinses. Do cool compresses over the cheek. You can also do warm saline gargle for relief. Take a soft diet and avoid any hard, spicy and sharp foods. Hope this information helps. Thanks and regards.
