- Minor ulcers: These are the most common, small, and heal in one to two weeks.

Mouth Ulcers – Why It Happens
Mouth ulcers can come from injuries, what we eat, and health problems. Knowing why they happen and their link to health is key. Stress and how we take care of our mouths also affect these painful sores.
Common Causes of Mouth Ulcers
Many things can lead to mouth ulcers. These include:
- Injury or irritation to the mouth lining from biting, braces, or dental work.
- Food allergies, especially to acidic foods like citrus fruits, which can provoke mucosal irritation.
- Vitamin deficiencies, especially in B12, iron, and folic acid, which are vital for healthy cellular regeneration in the mouth.
Underlying Health Conditions
Some health issues can make mouth ulcers worse. These

include:
- Celiac disease, which leads to gastrointestinal issues that can manifest in oral symptoms.
- Inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis, known for causing systemic inflammation.
- Autoimmune disorders that can disrupt normal bodily functions and contribute to recurrent ulcers.
Impact of Stress on Oral Health
Stress and oral health are closely tied. High stress can weaken our immune system and cause inflammation. This can lead to mouth ulcers. Managing stress is important for keeping our mouths healthy.
Preventing Mouth Ulcers
Mouth ulcers can be quite uncomfortable. To avoid them, it’s important to make dietary changes and practice good oral hygiene. A balanced diet helps keep your mouth healthy and reduces the risk of ulcers.
Dietary Changes
Changing your diet is key to keeping your mouth healthy. Eating foods rich in vitamins B and C, like fruits and veggies, helps your gums and speeds up healing. Try to avoid spicy, acidic, or sharp foods as they can irritate your mouth and cause ulcers.
Importance of Oral Hygiene
Good oral hygiene is vital in preventing mouth ulcers. Brushing and flossing regularly removes food and plaque, which can cause irritation. Using antibacterial mouthwash also helps keep your mouth clean and protects against infections. By focusing on these habits, you can greatly reduce your risk of getting mouth ulcers.
Treatment Options for Mouth Ulcers
Finding the right treatment for mouth ulcers is key to feeling better and healing faster. Over-the-counter remedies like topical anesthetics can offer quick pain relief. Products like benzocaine gels help ease pain, making it easier to eat and speak.
Home remedies can also help. Rinsing with salt water or using a baking soda paste can soothe and dry out ulcers. These methods are affordable and easy to find, making them a favorite for many.
If mouth ulcers don’t go away or are very painful, it’s best to see a doctor. Doctors can prescribe stronger medicines that tackle the root cause or reduce swelling. Knowing about these treatment options helps people make better choices for their mouth ulcers and oral health.
