Introduction
What are mouth ulcers?
Mouth ulcers, medically known as aphthous stomatitis, are painful, shallow erosions that form on the delicate mucous membranes of the oral cavity. Unlike cold sores, these lesions are not contagious and typically manifest as round or oval sores with a white or yellowish center surrounded by an inflamed red border. They frequently affect parts of the mouth, including the base of the gums, the soft palate, and the inner lining of the lips and cheeks.
Mouth ulcers can cause discomfort during everyday activities such as eating, drinking, and speaking. While most ulcers heal on their own within a few days to two weeks, recurring or long-lasting ulcers may require professional evaluation to identify underlying causes and ensure proper treatment.


Know the types of mouth ulcers:
Canker sore
Canker sores are non-cancerous, painful open lesions with a white or yellow center and a red border, distinct from contagious cold sores. While the exact cause is often unknown, they are frequently triggered by mouth injuries, nutritional deficiencies (like Vitamin B12 and iron), stress, or hormonal shifts. These common ulcers typically appear on the soft tissues of the mouth, such as the inner cheeks and tongue, and are more prevalent in women.
Oral lichen planus
This is a long-term swelling of the mouth’s inner lining that often appears as white, lacy patches or bright red gums. While it isn’t dangerous or contagious, it can be uncomfortable and may require simple medication to manage. Think of it as a persistent irritation that is easily treatable with professional care.
Drug-induced ulcers
Certain drugs, used during chemotherapy, specific antibiotics, or those affecting the immune system, can have an impact on the mouth’s lining and in turn trigger ulcers as a side effect. These sores are typically temporary and resolve once a healthcare professional adjusts or stops the medication. At Bharati Dental Hospital, we work closely with your prescribing physician to manage these symptoms safely without interrupting your essential treatments.
Leukoplakia
There are no specific reasons known for this condition. Long-term consumption of alcohol and tobacco are a possible cause of this ulcer type. While most leukoplakia patches are non-cancerous, some can be precancerous or occur alongside oral cancer. “Speckled leukoplakia” where white patches are mixed with red carries a higher risk of malignancy. If you notice any persistent changes in your mouth, visit Bharati Dental Hospital immediately for a professional medical evaluation.
At Bharati Dental Hospital, we use the VELscope as a high-tech addition to your oral exam. Basically, the special blue light helps us look deep into your tissues to identify oral precancer, cancer, or viral, bacterial, and fungal infections that might not be visible to the naked eye. The process is completely painless, non-invasive, and requires minimal time, giving you total peace of mind in just a few minutes.
Infectious mouth ulcers
Infectious ulcers are caused by germs like viruses, bacteria, or fungi. Viral versions often appear as painful clusters (like cold sores) on the lips or mouth, while bacterial and fungal types usually affect those with weaker immune systems. If your sores appear alongside a fever or swollen glands, it’s important to seek professional care.

Causes of mouth ulcers and tips to prevent them:
Most mouth ulcers are a sign that your oral environment is out of balance. Use these simple daily habits to keep your mouth healthy and pain-free.
1. Master Your Brushing Technique
Rough brushing can cause micro-trauma to your gums, which may trigger ulcers. Use a soft-bristled toothbrush and gentle technique to protect oral tissues. Avoid toothpaste containing Sodium Lauryl Sulfate (SLS), as it can irritate sensitive areas inside the mouth.
2. Watch Your "Trigger" Foods
Certain foods can irritate the oral lining and trigger ulcers in sensitive individuals. Limit acidic and spicy foods such as citrus fruits and tomatoes, and avoid sharp or crunchy snacks like chips that can scratch the soft tissues.
3. Fuel Your Body (The Vitamin Link)
Recurring ulcers may indicate nutritional deficiencies that affect oral health and healing. Ensure your diet includes Vitamin B12, iron, and folate through foods like leafy greens, eggs, chickpeas, and lean meats to support healthy tissues.
4. Manage Your Stress
Stress can increase inflammation in the body and contribute to the development of mouth ulcers. Practice relaxation techniques such as deep breathing, meditation, or short walks to help reduce stress levels and support overall oral health.
5. Stay Hydrated
A dry mouth can increase irritation and make it easier for ulcers to develop. Drink plenty of water throughout the day to maintain saliva flow, which naturally protects against bacteria and helps keep the oral environment balanced.
