Recurring Mouth Ulcers or Canker Sores: Causes, Home Remedies, and When to See a Dentist

Dentistaa · Gurugram · Updated 2026-09-30

Almost everyone in Gurugram has dealt with a small, painful sore inside the mouth at some point. These are commonly called mouth ulcers or canker sores, and while they are usually harmless, recurring ones can be frustrating and sometimes point to an underlying issue worth checking.

What Causes Mouth Ulcers

Mouth ulcers are small, round or oval sores that appear on the inside of the cheeks, lips, tongue, or gums. They are not the same as cold sores, which are caused by a virus and usually appear outside the mouth. Canker sores have several common triggers.

• Accidental cheek or tongue biting, or injury from a sharp tooth edge or braces
• Stress and lack of sleep
• Acidic or spicy foods, citrus fruits, and certain food sensitivities
• Hormonal changes, especially in women around their menstrual cycle
• Vitamin B12, iron, or folate deficiency
• Toothpaste containing sodium lauryl sulfate, which irritates some people's mouths
• Underlying conditions such as celiac disease, inflammatory bowel disease, or a weakened immune system

Most people get one or two ulcers occasionally. If they keep coming back every few weeks, it is worth paying attention to patterns and possible causes.

Home Remedies That Can Help

Simple ulcers usually heal on their own within a week to ten days. In the meantime, these steps can ease discomfort and support healing.

• Rinse gently with warm salt water two to three times a day
• Avoid spicy, acidic, or rough textured foods until the sore heals
• Use a soft bristled toothbrush and brush gently near the affected area
• Apply a small amount of over the counter oral gel meant for ulcers if needed
• Stay hydrated and try to reduce stress where possible
• Consider a vitamin rich diet with leafy greens, eggs, and dairy if deficiency is a concern

Avoid picking at the sore or repeatedly touching it with your tongue, as this can slow healing and increase irritation.

When Home Care Is Not Enough

While most ulcers are minor, certain signs suggest it is time to see a dentist rather than wait it out.

• The ulcer lasts longer than two to three weeks
• Ulcers keep recurring frequently, more than three or four times a year
• The sore is unusually large or extremely painful
• You develop a fever along with the ulcer
• Swallowing or speaking becomes difficult
• You notice white patches, unusual thickening, or the sore does not look like a typical ulcer

A dentist can examine the sore closely, rule out sharp teeth or ill fitting dental work as a cause, and check for signs that need further medical attention. In some cases, blood tests may be recommended to check for deficiencies or other conditions linked to frequent ulcers.

Cost of a Dental Check for Recurring Ulcers

A basic dental consultation to examine a mouth ulcer in Gurugram typically falls in a modest range, and additional tests like blood work, if recommended, are usually charged separately. The exact cost depends on whether further investigation or treatment of an underlying cause, such as a sharp tooth or ill fitting denture, is needed. As a typical range, consultations for this kind of concern tend to be affordable and are best confirmed directly with the clinic.

Prevention Tips for the Long Run

If you notice a pattern to your ulcers, small changes can reduce how often they appear.

1. Switch to a toothpaste without sodium lauryl sulfate if you suspect sensitivity
2. Get any sharp or broken teeth checked and smoothed
3. Manage stress through regular sleep and relaxation habits
4. Include more iron and B vitamin rich foods in your diet
5. Keep a simple log of what you ate or how stressed you were before an ulcer appeared

Recurring mouth ulcers are common and usually not serious, but persistent or unusual ones deserve a proper look. At Dentistaa in Sector 50, Gurugram, our dentists can help identify the cause and guide you toward the right treatment so you are not constantly dealing with painful sores.
