Mouth ulcers, though common and often benign, can cause discomfort and inconvenience in day-to-day activities. While they typically heal on their own within a week or two, natural home remedies for mouth ulcers can help relieve some symptoms associated with them.

From dietary adjustments to soothing herbal preparations, read on to learn about the best home remedy for mouth ulcers.

What Are Mouth Ulcers?

Typically, mouth ulcers manifest as sores inside the mouth and are usually red, yellow or white lesions, which may occur singly or in clusters. These ulcers develop on various oral surfaces and cause discomfort during eating, drinking, speaking and toothbrushing.

Some of the common oral surfaces that one can get ulcers on are:

  1. Gums.

  2. Over and under the tongue.

  3. The roof of the mouth.

  4. Inner cheeks.

  5. Lips.

While mouth ulcers may cause concern, it is crucial to understand that they are not sexually transmitted or contagious. Sharing food or drinks with someone who has mouth ulcers will not spread them. Generally, they are benign and resolve gradually within one or two weeks.

Types of Mouth Ulcers

Understanding the symptoms and characteristics of different types of mouth ulcers can help obtain accurate diagnosis and management. It also ensures timely intervention in any possibility of malignancy.

Cranker Sores

Cranker sores are the most prevalent type of mouth ulcer. These are often triggered by minor trauma, acidic foods or stress. They typically manifest as white or yellow lesions with red irritated skin as borders.

Oral Lichen Planus

Oral Lichen Planus are ulcers that are typically an immune system response. They manifest as lace-like white sores inside the mouth and tend to be itchy. These are commonly seen in women or individuals assigned female at birth (AFAB) aged 50 or older.


Leukoplakia is a result of excessive cell growth in the mouth. Usually characterised by white or grey patches in the mouth, these ulcers can cause chronic inflammation and irritation. Use of tobacco or smoking are some of the common causes of leukoplakia. Although these ulcers are typically noncancerous, they require monitoring for any potential changes.


Unlike leukoplakia lesions, erythroplakia patches are often cancerous or precancerous. They manifest as red, irritated patches behind the lower front teeth or under the tongue. Erythroplakia patches are typically associated with the use of tobacco and smoking.

Oral Thrush

Oral thrush is a type of mouth ulcer that manifests as red and creamy white patches in the mouth. This is caused by an overgrowth of yeast (candida albicans) in the mouth and is known to commonly occur after a course of antibiotics or in individuals with weak immune systems.

Mouth Cancer

Oral cancer lesions can appear as red or white mouth sores or ulcers that fail to heal. If a mouth ulcer persists for more than three weeks, it is advisable to seek immediate medical attention to rule out any malignancy.

What Causes Mouth Ulcers?

Although mouth ulcers can arise from various factors, irritation of the oral tissues is the primary reason for the onset of ulcers.

  • Minor tissue injuries:

    Minor tissue injuries resulting from dental procedures like cavity fillings or accidental biting of the cheek or tongue can cause abrasions just deep enough for an ulcer.

  • Allergic Reactions:

    Some individuals may experience ulcers due to allergies or an allergic response to certain foods or even bacteria present in the mouth.

  • Orthodontic appliances:

    Wearing orthodontic appliances like braces or retainers can lead to irritation of sensitive oral tissues because of the tough materials used in them. This can cause ulcers to form on the gums, the inner lining of the cheeks or even on the edges of the tongue.

  • Harsh toothpaste:

    The use of harsh or abrasive toothpaste or even mouthwash regularly can lead to irritation of the delicate oral tissues, leading to ulcers.

  • Acidic food:

    Consumption of acidic food like oranges, pineapple and strawberries can trigger ulcers. The bromelain (a protein-digesting enzyme) in pineapple and kiwi can also lead to ulcers as it is a common irritant for oral tissues.

  • Hormonal changes:

    Fluctuations in hormonal levels during menstruation cycles or due to medications may increase the likelihood of developing mouth ulcers.

  • Stress:

    Emotional stress can weaken the immune system and contribute to the development of oral ulcers.

  • Sleep deprivation:

    Inadequate sleep may compromise the immune system of the body, making individuals more prone to mouth ulcers.

In some cases, mouth ulcers could be a manifestation of an underlying health condition. Identifying the possible correlation between various health conditions and mouth ulcers plays a pivotal role in accurate diagnosis and timely intervention in serious health conditions. Recognising the underlying medical conditions can help find a suitable treatment not only for mouth ulcer pain relief but also for the underlying issue.

Home Remedies for Mouth Ulcers

While medical treatments are available, home remedies for mouth ulcers are more accessible and can aid in minimising symptoms. Here are some of the best home remedies for mouth ulcers :

Aloe Vera Gel

Extracted from the leaves of the Aloe Vera plant, Aloe Vera gel is known for its numerous medicinal properties. Used for treating various conditions, this gel also helps with mouth ulcer treatment.

Aloe Vera gel contains compounds such as acemannan, which are potent anti-inflammatory components. Since inflammation and irritation are very common symptoms of mouth ulcers, the gel relieves pain and discomfort by elevating any inflammation and helps promote faster healing.

Moreover, aloe vera also has antimicrobial properties that help prevent bacterial and fungal infections in the ulcerated area and reduce the risk of further complications by providing a safe environment for healing.

Furthermore, the gel’s rich water content acts as a natural moisturiser, preventing any dryness and cracking that could impact the healing process or cause pain. Its mild analgesic properties also help with mouth ulcer pain relief.

Apple Cider Vinegar

Apple Cider Vinegar is easily one of the best home remedies for ulcers in the mouth.

It possesses antimicrobial properties that help treat mouth ulcers. The acetic acid present in Apple Cider Vinegar can inhibit the growth of bacteria, fungi and even viruses.

This property of acetic acid helps reduce the inflammation around the ulcers, aids in mouth ulcer pain relief and also promotes faster healing. Apple Cider Vinegar is also known to promote tissue healing with its anti-inflammatory properties.

Moreover, the acidity of Apple Cider Vinegar also creates an unfavourable environment for the growth of any microorganism. Termination of harmful microorganisms prevents any further development of ulcers or even worsening of the present lesions.

Baking Soda

Since most ulcers develop in acidic environments, the alkalinity of baking soda helps neutralise the acids and reduce inflammation and pain associated with the ulcers. Baking soda also helps manage the pH of the mouth, ensuring it does not promote any further development in the ulcers. This does not just help with the inflammation but also with mouth ulcer pain relief and tooth decay.

To use baking soda for mouth ulcer treatment, follow these steps:

  • Mix 1 TBSP of baking soda with a small amount of water.

  • Apply this mixture directly on the ulcer with a clean cotton swab or finger.

  • Leave the mixture on for about 5 minutes.

  • Rinse thoroughly with water once done.

  • Repeat this process several times a day to ensure a speedy recovery.

Cabbage Juice

Cabbage contains potent anti-inflammatory compounds such as anthocyanins and glucosinolates which help with mouth ulcer pain relief. Moreover, Vitamin C, Vitamin K and Vitamin B6 present in cabbage play a crucial role in maintaining oral health and supporting the body's healing process.

In addition to analgesic properties, clove oil is a known antiseptic which kills the bacteria that may be present in the oral lesions or the mouth. This process will not only provide a safe environment for healing but also speed up the process by reducing inflammation.

Moreover, the anti-inflammatory compounds in coconut oil help reduce swelling and pain associated with mouth lesions. The oil's nourishing properties too, help ensure the tissues do not dry out and stay naturally moisturised.
