It’s important to remember that oral swelling can be caused by a slew of various reasons. Infections, allergies, cysts, viruses, an exostosis or neoplasms can all be potential causes. Of course, if you notice new or unexplained swelling in your mouth, it’s time to get in and see your dentists.
In many cases, painful swelling in your mouth can indicate a dental infection, often requiring drainage and treatment with antibiotics. Even if the pain diminishes after a few days, still get in and see your dentists, since the source of the infection needs to be determined to be properly treated.
If an endodontic abscess is the cause of the pain, a root canal or extraction may be necessary. The tooth may also be vertically fractured, which (if it’s severe enough) will require extraction.
Now, as a bit of a stress-reliever, not all oral swelling is caused by infection; oral cysts are quite common, and can cause moderate to severe pain.
No matter what you may believe the cause of oral swelling or pain to be, the important thing to remember is to see your dentist when these symptoms arise; they can’t be treated if they’re not brought to your dentist’s attention!
