Mouth Ulcers and Canker Sores: Causes, Relief, and Red Flags
Almost everyone in Sector 38, Gurugram has dealt with a small, painful sore inside the mouth at some point. These mouth ulcers, often called canker sores, can make eating, talking, and even smiling uncomfortable. The good news is that most of them are harmless and heal on their own. Understanding why they happen and when to worry can save you unnecessary discomfort and help you know when it is time to see a dentist.
What Causes Mouth Ulcers
Mouth ulcers are small, shallow sores that form on the soft tissues inside the mouth, such as the inner cheeks, lips, tongue, or gums. They are usually round or oval with a white or yellowish centre and a red border. Several everyday factors can trigger them.
- Minor injury: Accidentally biting your cheek, a rough edge on a tooth or denture, or aggressive brushing can irritate the tissue.
- Stress and fatigue: Many patients notice ulcers appear during busy or stressful periods.
- Certain foods: Citrus fruits, tomatoes, and spicy or acidic foods can irritate sensitive mouths in some people.
- Nutritional gaps: Low levels of vitamin B12, folate, or iron are linked to recurring ulcers.
- Hormonal changes: Some women notice ulcers around their menstrual cycle.
- Toothpaste ingredients: Sodium lauryl sulphate, found in many toothpastes, has been associated with ulcers in sensitive individuals.
- Underlying conditions: Occasionally, ulcers relate to digestive issues or immune-related conditions, especially if they are frequent or severe.
Home Remedies for Relief
Most simple mouth ulcers heal within a week to ten days without any special treatment. While healing, these steps can ease the discomfort.
- Warm salt water rinse: Dissolve half a teaspoon of salt in a cup of warm water and rinse gently a few times a day.
- Avoid trigger foods: Stay away from spicy, salty, acidic, or very hot foods until the ulcer heals.
- Use a soft toothbrush: This reduces irritation to the sore area while still keeping your mouth clean.
- Over-the-counter gels: Topical gels available at pharmacies can numb the area temporarily and protect the ulcer while eating.
- Cold foods and ice: Cold water, ice chips, or chilled yoghurt can soothe the area between meals.
- Stay hydrated: Drinking enough water supports healing and keeps the mouth comfortable.
If you get ulcers often, keeping a simple food and stress diary can help identify personal triggers over time.
Red-Flag Signs That Need a Dentist's Attention
While most mouth ulcers are nothing to worry about, certain signs suggest it is time to book a check-up rather than wait it out.
- The ulcer lasts longer than two to three weeks without healing.
- It keeps coming back in the same spot repeatedly.
- The sore is unusually large, hard, or has thickened, raised edges.
- You have several ulcers appearing at the same time across the mouth.
- There is significant pain that does not respond to home care.
- You notice unexplained weight loss, fever, or swollen glands alongside the ulcer.
- The sore is painless but does not go away, which can sometimes need closer evaluation.
A dentist can examine the area, rule out a sharp tooth edge or ill-fitting denture as the cause, and check for any underlying issues that may need attention. In some cases, a referral for blood tests to check vitamin or mineral levels may be suggested.

Frequently asked questions
How long should a normal mouth ulcer take to heal?
Most simple ulcers heal within 7 to 10 days on their own. If a sore lasts longer than two weeks, have it checked.
Are mouth ulcers contagious?
No, common canker sores are not contagious. This is different from cold sores caused by the herpes virus, which appear outside the mouth and can spread.
Can stress really cause mouth ulcers?
Yes, stress is a well known trigger for many people, likely because it affects immunity and eating habits, though the exact link is still being studied.
Should I stop brushing the area if I have an ulcer?
No, keep brushing gently with a soft brush. Avoid the ulcer directly if it hurts, but do not skip cleaning your teeth altogether.
