Last Updated on November 5, 2023 by Nurse Vicky

What Is the Treatment For Mouth Ulcers?

Mouth ulcers can be quite a nuisance, causing discomfort and pain that can disrupt your daily life. These small, painful sores can appear on the inside of your cheeks, lips, tongue, and even the roof of your mouth.

If you’ve ever had a mouth ulcer, you know just how frustrating it can be. But fear not, we’re here to guide you through what mouth ulcers are, why they occur, and most importantly, the various treatment options available.

Understanding Mouth Ulcers

Mouth ulcers, also known as canker sores or aphthous ulcers, are shallow, round or oval sores that form inside the mouth. They are usually white or yellow with a red border and can be quite painful. While they are not contagious, they can make eating, drinking, and even speaking uncomfortable.

Types of Mouth Ulcers

There are three primary types of mouth ulcers:

  1. Minor Ulcers: These are the most common and usually small, with a diameter of less than 1cm. They typically heal within 1-2 weeks.
  2. Major Ulcers: These are larger, deeper, and more painful than minor ulcers. They can take up to six weeks to heal and may leave a scar.
  3. Herpetiform Ulcers: These are clusters of multiple, tiny ulcers that can merge to form one large sore. They tend to be the most painful and can last from one week to several months.

Why Do Mouth Ulcers Occur?

Mouth ulcers can be triggered by various factors, such as:

  • Stress: Emotional stress can weaken the immune system and lead to mouth ulcers.
  • Food Sensitivities: Certain foods like citrus fruits, nuts, and spicy foods can irritate the mouth and trigger ulcers.
  • Injury: Accidental biting, dental braces, or sharp edges of teeth can cause ulcers.
  • Hormonal Changes: Women may experience mouth ulcers during their menstrual cycle.
  • Underlying Health Conditions: In some cases, mouth ulcers can be a symptom of an underlying health issue.

Treatment Options for Mouth Ulcers

Now that we understand what mouth ulcers are and why they occur, let’s explore the treatment options available to provide you with much-needed relief.

1. Over-the-counter (OTC) Remedies

You can find a variety of OTC products like oral gels, creams, and mouthwash designed to alleviate the pain and discomfort of mouth ulcers.

2. Home Remedies

  • Saltwater Rinse: Gargling with warm salt water can help reduce inflammation and promote healing.
  • Honey: Applying honey directly to the ulcer can speed up the healing process.

3. Prescription Medications

In severe cases or when ulcers are caused by an underlying medical condition, your healthcare provider may prescribe medications such as corticosteroids or antimicrobial mouthwash.

4. Lifestyle Changes

Making a few lifestyle adjustments can also help prevent and manage mouth ulcers. Avoiding trigger foods and managing stress can go a long way in reducing the frequency of ulcers.

5. Oral Hygiene

Maintaining good oral hygiene is essential. Using a soft-bristle toothbrush and avoiding abrasive toothpaste can help prevent injury to the mouth.


1. Can mouth ulcers be a sign of a more serious health condition?

While most mouth ulcers are harmless and resolve on their own, in some cases, recurrent or persistent ulcers may be a symptom of an underlying health issue. It’s advisable to consult a healthcare provider if you have concerns.

2. Are mouth ulcers contagious?

No, mouth ulcers are not contagious. You can’t spread them through close contact or by sharing utensils.

3. How long do mouth ulcers typically last?

The duration of mouth ulcers can vary. Minor ulcers usually heal within 1-2 weeks, while major and herpetiform ulcers may take longer to resolve.

4. Can I prevent mouth ulcers?

While you can’t always prevent mouth ulcers, you can reduce the risk by avoiding trigger foods, managing stress, and maintaining good oral hygiene.

5. Do I need to see a dentist for mouth ulcers?

You can initially manage mouth ulcers at home or with OTC products. However, if they persist or become more severe, it’s a good idea to consult a dentist or healthcare professional.

6. Is there a link between mouth ulcers and vitamin deficiencies?

Yes, vitamin deficiencies, especially of B vitamins, can contribute to the development of mouth ulcers. Ensuring a balanced diet can help prevent this.

7. Can children get mouth ulcers?

Yes, children can get mouth ulcers. They are not exclusive to adults and can affect individuals of all ages.

We hope this comprehensive guide has provided you with valuable insights into the treatment of mouth ulcers. Remember that everyone’s experience is unique, and what works for one person may not work for another. If you have persistent or severe ulcers, it’s always best to seek professional medical advice.


Mouth ulcers, though painful, are a common occurrence and can usually be managed effectively with the right treatment. If you’re experiencing persistent or severe ulcers, it’s essential to consult a healthcare professional for a proper diagnosis and treatment plan.
