I have had a horrible canker sore for days. I normally have a pretty high pain tolerance, but last night, I was unable to eat dinner. The spot looks terrible and is the size of a corn kernel. It’s raised and red and white on top. I should mention that this is not the first canker sore I’ve experienced, but it’s definitely the worst canker sore I’ve ever had. Should I consult an emergency dentist? Or, would it be better to see my regular doctor?

Thanks,
Christine

Dear Christine,

If you have not yet tried any at-home canker sore remedies, it may be too soon for an emergency dentist. Typically, spots such as these heal themselves in a matter or 10-14 days. However, it’s a matter of managing the pain and discomfort until that time.

Many products can provide canker sore relief. A good starting point would be an oral anesthetic from the dental aisle of your local pharmacy or grocery store. Normally these come in a tube or gel-like pads that go on a tissue. If the canker sore appears to have become infected, a topical antiseptic should be applied to the area. Another option is a product made for killing germs, or do a rinse with part water, part hydrogen peroxide. Listerine works well, too, as some people have reported quick pain relief from it.

True canker sores can have many causes. Biting your cheek, injury, stress, allergies, or friction from dental tools, are some possible causes. In addition, there are other problems that may appear and feel like a canker sore, such as cancer or viruses. If you have several canker sores, it would be a good idea to see a doctor or dentist for an evaluation. If it doesn’t improve after a couple of weeks of developing the canker sore, or it the pain worsens, you should schedule a checkup. These appointments do not have to be with an emergency dentist unless the pain is unbearable.
