Canker sore pain? Get relief with our canker sore guide.

Do you have a painful white spot inside your lip or cheek? It could be a canker sore!

What causes canker sores in the mouth?

As of today, doctors and researcher have not yet pinpointed the exact cause of canker sores. However, several studies have shown a few possible Opens new tab to Mayo Clinic websitetriggers. These include:

  • Trauma or minor injury in your mouth (over brushing, sports-related, biting your cheek, hot food burn, dental work, etc.)
  • Emotional stress or anxiety
  • Changes in hormonal levels (menstruation)
  • Toothpaste or mouthwash with sodium lauryl sulfate
  • Food sensitivities (particularly spicy, citrus or acidic foods or drinks)
  • Lack of iron, zinc, vitamin B-12, or folic acid

Research also shows ulcers were more common in people with certain diseases and conditions, such as:

How do you get rid of canker sores in the mouth?

Better yet, how do you get rid of canker sore pain?

Unfortunately, there is no cure for canker sores (yet). But the good news is these ulcers will heal on their own.

If you experience pain with a canker sore, the time it takes for it to heal can feel like forever. So, to help you treat your canker sore symptoms, we recommend the following:

  • Taking over-the-counter pain relievers or anti-inflammatories (Advil)
  • Numbing the areas with a topical anesthetic (Orajel or Orabase)

What should you do if your canker sore doesn’t heal on its own?

If you can’t get pain relief with the treatments above or your canker sore shows no signs of healing, then we recommend visiting our dentist in Columbia, SC.

Dr. Griffin can examine your oral health and prescribe a treatment. Some treatments include:

  • Painkillers
  • Steroid inhalers (beclometasone)
  • Steroid tablets (doxycycline)
  • Debacterol

If your ulcer hasn’t healed within three weeks, then we advise you to visit us soon. This could be a sign of an underlying illness or disease, including oral cancer that sometimes starts as an unusual, unhealing mouth ulcer.
