Mouth Ulcers Causes

Accidental injuries, like biting your cheek: Sometimes, a simple accident can lead to the formation of mouth ulcers.

Aphthous ulcers: These recurring ulcers affect many individuals and may be linked to various factors, such as diet or nutritional deficiencies.

Certain medications: Some medications can trigger the development of mouth ulcers as a side effect.

Mouth rashes: Allergic reactions or skin conditions in the mouth can contribute to the formation of ulcers.

Infections: Viral, bacterial, or fungal infections can also be culprits behind the appearance of mouth ulcers.

Mouth sores may be caused by irritation from:

  • A sharp or broken tooth or poorly fitting dentures
  • Biting your cheek, tongue, or lip
  • Burning your mouth from hot food or drinks
  • Braces
  • Chewing tobacco
  • A weakness in your immune system (for example, from the cold or flu)
  • Hormone changes
  • Stress
  • Lack of certain vitamins and minerals in the diet, including vitamin B12 or folate
  • Another illness, especially if there is a fever
  • Hormone changes (such as menstruation)
  • Stress
  • Sun exposure


  • Stubborn ulcers could signal something serious, like mouth cancer, so it’s essential to monitor them closely and seek medical attention if needed.
  • Most ulcers heal within 10 to 14 days on their own, but if they persist or worsen, it’s advisable to consult a healthcare professional.
  • Aphthous ulcers may be linked to low levels of vitamin B, folate, or iron, highlighting the importance of maintaining a balanced diet for oral health.

Types of Mouth Ulcers:

There are many different types of mouth sores and lesions, including:

  1. Canker sores: These are the most common type of mouth ulcer, often appearing as round or oval sores with a white or yellow center and a red border. Canker sores can cause discomfort while eating or drinking and typically heal on their own within one to two weeks.
  2. Leukoplakia: Leukoplakia presents as thick, white patches on the inside of the mouth, such as on the cheeks, gums, or tongue. Often caused by irritation, such as from smoking or chewing tobacco, leukoplakia may indicate a precancerous condition and should be assessed by a dentist or doctor.
  3. Gingivostomatitis: This viral infection leads to inflammation of the gums and mouth lining, commonly observed in children. Symptoms include painful mouth sores, fever, and swollen glands, usually caused by the herpes simplex virus (HSV) and treatable with antiviral medications.
  4. Oral Cancer: Oral cancer manifests as mouth ulcers that persist for weeks without healing. Accompanying symptoms may include persistent pain, difficulty swallowing, or changes in voice, highlighting the importance of early detection and treatment.
  5. Oral Lichen Planus:a chronic inflammatory condition affecting the mouth’s mucous membranes, resulting in white, lacy patches or sores on the cheeks, tongue, or gums. While the precise cause is unknown, oral lichen planus may be linked to an abnormal immune response.
  6. Oral Thrush: Caused by the overgrowth of Candida yeast in the mouth, oral thrush appears as white, creamy patches on the tongue, inner cheeks, or roof of the mouth. More prevalent in infants, older adults, and those with weakened immune systems, oral thrush requires treatment to alleviate symptoms.

These examples illustrate the diverse range of mouth ulcers that can occur. If you encounter persistent or severe mouth sores, seeking professional medical advice is crucial for proper diagnosis and treatment.

Symptoms of mouth ulcers:

Painful sores: These pesky ulcers can appear anywhere inside the mouth, whether it’s the cheeks, roof, or tongue. They’re like unwelcome guests crashing the oral party!

Sensitivity to certain foods: Say goodbye to your favorite salty snacks or spicy delights! These foods can turn from delicious to downright painful when they come into contact with those ulcers.
Discomfort from dental appliances: If you’re sporting dentures, braces, or mouth splints, beware! They might unintentionally aggravate those already-irritated sores, adding insult to injury.
Additional symptoms during severe outbreaks: When things get serious, you might experience more than just mouth pain. Fever, fatigue, and swollen glands might join the party, making you feel like you’ve been hit by a mouth ulcer tsunami!

Diagnosis and Tests for Mouth Ulcers:

Visual examination: A healthcare provider can usually diagnose a mouth ulcer by just looking at it. They’ll check its appearance and where it is in your mouth.

Medical history: Your healthcare provider might ask about your medical past, like recent illnesses or medicines you’re taking, to find out what’s causing the mouth ulcer.

Blood tests: Sometimes, if the mouth ulcers are bad or there might be another health problem, your healthcare provider might order blood tests. These tests can find infections, not enough nutrients, or other health problems that might be causing the ulcer.

When to See a Doctor:

People who often get mouth ulcers might not always know when to see a doctor. However, there are times when it’s important to see a doctor right away. 

Some of these situations include:

1. Having a non-painful ulcer in one or more areas of the mouth.
2. Noticing unusual ulcers in a new spot in the mouth
3. Seeing ulcers that are spreading
