Canker sores on the inside of the mouth are painful ulcers caused by irritation, stress, or immune response and usually heal within two weeks.
Understanding Canker Sores On Inside Of Mouth
Canker sores, medically known as aphthous ulcers, are small, shallow lesions that develop on the soft tissues inside your mouth. Unlike cold sores, which occur outside the mouth and are caused by viruses, canker sores appear inside the oral cavity and are not contagious. These sores can be quite painful and may interfere with eating, speaking, or even swallowing.
The exact cause of canker sores remains somewhat elusive. However, they often result from a combination of factors such as minor injury to the mouth’s lining (like accidentally biting your cheek), stress, hormonal changes, or certain food sensitivities. Some people may also experience canker sores due to an underlying immune system response that mistakenly attacks the mucous membranes.
Canker sores typically present as round or oval ulcers with a white or yellowish center and a red border. They can range in size from a few millimeters to over a centimeter in diameter. Most heal spontaneously within 7 to 14 days without scarring.
Common Triggers Behind Canker Sores On Inside Of Mouth
Pinpointing what sparks these painful ulcers can be tricky since triggers vary widely among individuals. Still, several common culprits consistently emerge:
1. Mechanical Trauma
Everyday activities such as brushing teeth too hard, dental work, or accidentally biting the inside of your cheek can damage delicate oral tissues. This trauma often leads to sore formation.
2. Nutritional Deficiencies
Deficiencies in vitamins like B12, folic acid, zinc, and iron have been linked to increased frequency of canker sores. These nutrients play vital roles in maintaining healthy mucous membranes and immune function.
3. Stress and Hormonal Changes
Emotional stress is a notorious trigger for many health issues—including canker sores. Likewise, hormonal fluctuations during menstruation or pregnancy may increase susceptibility.
4. Food Sensitivities and Allergies
Certain acidic or spicy foods (think citrus fruits, tomatoes, coffee) can irritate the mouth lining and provoke ulcer formation in sensitive individuals.
5. Medical Conditions
Some systemic diseases like celiac disease, Crohn’s disease, and Behçet’s syndrome manifest with recurrent oral ulcers as a symptom.
Symptoms That Accompany Canker Sores On Inside Of Mouth
Canker sores usually start as small red bumps before developing into painful ulcers within one to two days. Here are some typical symptoms:
- Painful Sensation: The sore is tender to touch and worsens with eating salty or spicy foods.
- Burning or Tingling: Many report a tingling feeling before the sore fully develops.
- Swelling: Surrounding tissues may become slightly swollen.
- Difficult Eating or Speaking: Discomfort may make chewing and talking challenging.
- Mild Fever: In severe cases with multiple ulcers, mild fever or swollen lymph nodes might occur.
Most of these symptoms fade as the ulcer heals naturally over days.
Treatment Options For Canker Sores On Inside Of Mouth
Since canker sores usually resolve on their own within two weeks, treatment primarily focuses on relieving pain and promoting faster healing.
Over-The-Counter Remedies
A variety of topical gels and ointments containing ingredients like benzocaine or hydrogen peroxide help numb pain and reduce inflammation. Mouth rinses with antimicrobial properties also prevent secondary infections.
Home Remedies That Work
You don’t always need fancy meds to soothe these pesky sores—simple home care often does wonders:
- Saltwater Rinse: Dissolve half a teaspoon of salt in warm water and rinse your mouth several times daily to reduce bacteria.
- Baking Soda Paste: Mixing baking soda with water into a paste applied directly to the sore neutralizes acids that irritate it.
- Coconut Oil: Applying coconut oil provides antimicrobial effects while soothing inflamed tissue.
- Avoid Irritants: Stay away from spicy foods, acidic fruits, tobacco products, and alcohol until healed.
Prescription Treatments for Severe Cases
If you experience large ulcers that don’t heal after three weeks or recurrent outbreaks disrupting daily life, consult a healthcare provider. They may prescribe corticosteroid mouthwashes or topical immunosuppressants that reduce inflammation more effectively than OTC options.

The Healing Process Explained
The body’s natural healing mechanism kicks in immediately after an ulcer forms. White blood cells rush to the site to clear out damaged cells while new tissue grows underneath.
Typically:
- Day 1-3: Ulcer appears red with swelling; pain peaks during this phase.
- Day 4-7: White/yellowish membrane covers the sore; inflammation begins decreasing.
- Day 8-14: New tissue regenerates; ulcer shrinks until fully healed without scars.
Proper oral hygiene during this period is crucial to avoid bacterial infections that could slow recovery.
