Mouth ulcers, also known as canker sores or aphthous stomatitis, are tiny blisters or lesions that develop in the mouth. Mouth ulcers can be caused by various things, including accidents and allergies, even though there isn’t a single explanation for them.

What is a Mouth Ulcer?

A mouth ulcer is a non-contagious tiny lesion that can appear on the lips, tongue, gums, cheeks, or roof of the mouth. The underlying illness known as “Aphthous Stomatitis” is typically the cause of recurring mouth ulcers.

An ulcer can be extremely painful when touched and frequently causes discomfort. When inflamed, it might get in the way of your normal chewing and become bite-prone. Ulcers on the cheeks/gums are the most bothersome, as they are frequently bitten/chewed by accident. There should be worry if a mouth ulcer grows larger than its typical range of millimetres to centimetres. A typical mouth ulcer has a light-yellow core and a bright red outside, which is due to swelling.

Major Causes of Mouth Ulcers

The most frequent type of mouth ulcer is caused by trauma and does not generally indicate an underlying medical issue. The following is a list of possible causes of mouth ulcers:

  • A scratch or scrape on the inside of the mouth, maybe caused by your teeth or oral equipment like orthodontics.
  • A burn in your mouth is caused by eating hot or acidic meals.
  • Gastric acid may enter the mouth due to acid reflux.
  • Tooth grinding or bruxism can lead to ulcers.
  • Chewing pens or other sharp objects.
  • Oral health issues, including malignant and precancerous diseases.

Symptoms of Mouth Ulcers

  • Mouth ulcers may be more likely to develop or exhibit severe symptoms if:
  • You experience fatigue, tension, or anxiety.
  • Your teeth are misplaced or crooked.
  • hormonal changes are occurring in you (such as pregnancy)
  • You just gave up smoking.
  • Your family is prone to mouth ulcers.

Some people suffer from reoccurring mouth ulcers known as aphthous ulcers. Addressing the underlying cause is necessary for treating these ulcers.

Mouth Ulcer Treatment

Naturally occurring mouth ulcers normally disappear if they are not continually scraped or bitten. However, if they are causing substantial pain and may interfere with your usual life, it may be preferable to expedite the procedure. Despite having no scientific support, a lot of home treatments have been debated on forums and the internet. Therefore, it is recommended to utilise appropriate treatments, which have scientific and oral hygienist treatments support and can speed up ulcer healing by up to twice. The following is a list of some appropriate treatments:

  • Possibly the most effective technique to treat a mouth ulcer is to avoid irritating or interfering with the afflicted region. This can be accomplished by not chewing on that side of the mouth. Furthermore, avoid continually touching your ulcer with your tongue or fingers.
  • Painkillers can frequently help alleviate the discomfort caused by the ulcer. Additionally, it can distract you from the ulcer and prevent you from touching it frequently to check on its discomfort, which would aid in its healing. Anti-inflammatories (Ibuprofen and Aspirin are the most common types) are the best choice as they help fight infection and relieve pain. Since paracetamol is not an anti-inflammatory, it is not advised.
  • Rinsing with warm salty water can help lessen the swelling caused by the ulcer. This solution serves as a mild antiseptic, killing dangerous inflammation-causing bacteria while also avoiding harm to the infected tissue. ¬†Rinse the area 2-3 times a day to aid healing and prevent problems. Although applying salt to a wound may appear strange and taste bad, it shouldn’t hurt and will probably be quite helpful.

If in doubt, get a professional opinion! Seek the advice of a dentist, who may refer you to a hospital or perform a biopsy if the ulcer seems worrisome. This is particularly the case if the ulcer has persisted in the same location for more than three weeks without moving.


Mouth ulcers can be uncomfortable and inconvenient even though they are often not harmful. While they normally heal on their own, the right treatment is necessary to speed up the healing process. The three most successful tactics are to rinse with warm, salted water, to avoid irritating yourself, and to use painkillers sparingly. To rule out any underlying problems, it’s imperative to contact a specialist if ulcers worsen or persist. Individuals can enhance their dental health and general well-being by mitigating symptoms and expediting healing through the utilisation of suitable treatments and an awareness of underlying reasons. Remember that proactive care and timely intervention can help you manage mouth ulcers effectively.
