Mouth ulcers, also known as canker sores, are tiny lesions inside the mouth. Mouth ulcers have no clear aetiology. However, they might be triggered by trauma, allergies, or sensitivities.

Mouth ulcers are little lesions that develop on the gums, lips, inner cheeks, or palate. Various circumstances, including small injuries, hormone changes, and mental stress, cause them. Mouth ulcers are not contagious and heal on their own. However, there are treatments available to assist in relieving pain and suffering.

They can be caused due to intake of medicines for certain medical conditions. For occasions like weddings, it is very important to maintain oral hygiene to avoid ulcers. In such cases, dietitians suggest special diets in plans like wedding makeovers.

What Are Mouth Ulcers?

A mouth ulcer is the destruction or erosion of a portion of the fragile tissue that borders the mouth's interior. A variety of factors can cause mouth ulcers. Injury is the most prevalent cause. Other reasons include aphthous ulcers, certain drugs, oral skin rashes, viral, bacterial, and fungal infections, pollutants, and certain medical problems. A persistent ulcer might be a symptom of mouth cancer. Most mouth ulcers are safe and heal independently in 10 to 14 days without requiring therapy.

A mouth ulcer is a soft tissue sore in the wall of your gums, tongue, inner cheeks, lips, or palate. They are often yellow or red and can be extremely painful. Aphthous ulcers and canker sores are other names for mouth ulcers.

Symptoms Of Mouth Ulcers

Mouth ulcers are easily identified.  The symptoms differ depending on the aetiology. However, they commonly include blisters on the inside of the mouth, such as on the tongue or the insides of your cheeks or lips, that are painful and intensify when you eat, drink, or talk

Other signs and symptoms might include:

  • The ulcer is swollen.
  • Soreness when cleaning your teeth has increased.
  • Pain that becomes worse when you eat spicy, salty, or sour meals.

What Causes Mouth Ulcers?

The majority of individual mouth ulcers are triggered by items you may avoid, such as:

Biting the inside of your cheek due to ill-fitting dentures, braces, rough fillings, or sharp tooth cuts or burns while eating or drinking - for example, hard food or hot drinks, a food intolerance or allergy negatively affecting your gums with a toothbrush or irritating toothpaste feeling tired stressed, or anxious

They can be triggered by factors you cannot necessarily control, such as

  • Hormonal changes such as during pregnancy
  • Your genes 
  • Certain families have a higher incidence of mouth ulcers drugs such as some NSAIDs, beta-blockers, or nicorandil quitting smoking 
  • Persons who quit smoking may develop mouth ulcers.

Home Remedies For Mouth Ulcers

Home Remedies for mouth Ulcers

Various treatments and pharmaceuticals can give temporary respite from the disease on the market. Unfortunately, none of these traditional treatments provides a long-term cure for mouth ulcers. 

Simple home treatments are the most effective in this regard. Here we have listed some effective home remedies to cure ulcers:

1. Honey

Honey offers several health benefits. Nevertheless, you may be surprised to learn that it may also be used to treat oral ulcers. Put honey on the ulcers and leave it alone. As the ulcers are within the mouth, you may accidentally consume the honey with your saliva. However, you must continue to apply honey to the ulcer sites every few hours.

2. Ice Cube

Applying a little ice cube to canker sores instantly relieves them. Put an ice cube in a dry cloth and apply it to the sore. The cold will not only dull the feeling, but it will also reduce inflammation. This is quite beneficial when there are severe canker ulcers around the lips.

3. Coconut Oil

Throughout much of India, coconut oil is utilised for several purposes. However, few individuals are aware of its therapeutic powers for mouth ulcers. Simply apply a small amount of coconut oil to the ulcer's surface and leave it on. You can also use it before going to bed at night. The same substance can also treat mouth ulcers as an anti-inflammatory and analgesic. Applying the oil might help relieve the pain caused by mouth ulcers.

4. Saltwater

In a cup of lukewarm water, dissolve a spoonful of salt. Now vigorously gargle with this liquid. After that, gargle with plain water to eliminate the salty taste from the mouth. Using this method, you can relieve a portion of the pain and discomfort associated with a mouth ulcer. Salt's antibacterial qualities are widely recognised.

5. Alum Powder

Potassium aluminium sulphate is used to make alum powder. It is frequently used to conserve food and pickled vegetables. Alum contains astringent characteristics that may aid in the shrinking of tissues and the drying of canker sores.

The Final Say

Fortunately, mouth ulcers usually heal on their own, and the discomfort connected with an ulcer usually goes away within a few days. Some drugs, in the form of topical creams and solutions, may assist with swelling and pain, although they are not always essential for a full recovery. People should aim to minimise stress and worry as much as possible to avoid repeat breakouts.


1. Are mouth ulcers an early sign of cancer?

Yes, on occasion. A persistent mouth ulcer might be an indication of oral cancer. Most ulcers produced by oral cancer occur on or beneath the tongue.

2. Are mouth ulcers contagious?

Aphthous ulcers are not infectious and cannot be spread by kissing or sharing utensils. However, mouth ulcers caused by illnesses such as viruses, bacteria, or yeast might be communicable.

3. How long does it take to heal mouth ulcers?

A mouth ulcer usually heals in 7-14 days. Largemouth ulcers might require a month or many months to heal.
