We’ve all experienced mouth ulcers at some point, those small and painful sores that make eating, drinking, and even talking uncomfortable. While most mouth ulcers are harmless and heal within one to two weeks, recurring or severe ulcers may point to a deeper health concern that shouldn’t be ignored.
At Dentology by Dr. Sagar, Ludhiana, we believe understanding the cause behind every oral symptom is important for maintaining both your oral and overall health.
What Are Mouth Ulcers?
Mouth ulcers, also called canker sores, are small lesions that form on the soft tissues of your mouth, including the inner cheeks, lips, tongue, or gums. They are not contagious and usually appear as round or oval spots with a white or yellow center and a red border.
Common symptoms include:
- Pain or burning inside the mouth
- Discomfort while eating or speaking
- Swelling or redness around the sore
Common Causes of Mouth Ulcers
Most mouth ulcers are caused by minor irritation or temporary health changes. Some common causes include:
Minor Injuries
Accidental cheek biting, aggressive brushing, or irritation from sharp teeth or braces.
Hormonal Fluctuations
Changes in hormones, especially in women, can trigger recurrent ulcers.
Nutritional Deficiencies
Low levels of vitamin B12, folic acid, iron, and zinc can increase the chances of frequent ulcers.
Food Sensitivities
Citrus fruits, spicy foods, and acidic drinks can irritate the mouth lining.
Poor Oral Hygiene
Bacterial buildup can inflame the soft tissues and lead to sores.
The Role of Stress in Causing Mouth Ulcers
Stress is one of the most common yet overlooked triggers of mouth ulcers. When your body is under emotional or physical stress, several changes occur:
Weakened Immune Response
Stress reduces immunity, which makes the mouth more vulnerable to irritation and inflammation.
Hormonal Imbalance
Stress hormones like cortisol can slow down healing and increase the chances of ulcers.
Teeth Grinding or Cheek Chewing
Many people grind their teeth or chew the inside of their cheeks when stressed, which directly causes ulcers.
Lifestyle Changes During Stress
Skipping meals, lack of sleep, and neglecting oral hygiene during stressful times can also contribute to mouth sores.
If you experience more ulcers during exams, work pressure, or emotional phases, stress may be the underlying reason.
When Mouth Ulcers Indicate a Bigger Health Problem
You should seek dental or medical help if you have ulcers:
- Keep coming back
- Lasts more than two to three weeks
- Are unusually large or painful
- Appear with fever or swollen lymph nodes
- Come along with fatigue or digestive issues
These may be linked to deeper health issues, such as:
Gastrointestinal Disorders
Crohn’s Disease, Ulcerative Colitis, and Celiac Disease can cause recurring ulcers.
Immune System Disorders
Conditions like Lupus or Behçet’s disease may lead to chronic mouth sores.
Infections
Certain viral and bacterial infections can cause ulcer-like lesions.
Oral Cancer (Rare)
A non-healing ulcer lasting more than three weeks should always be checked by a dentist.
