They are also known as “Stomatitis-Ulcerative” and “Oral Ulcers”. Mouth ulcer signs and symptoms are very common. Most of the times ulcers presence can be felt under the tongue, on the sides of tongue, inner layer of lips, cheeks and the soft palate. Rarely do they occur near throat. Sometimes they are occurred naturally as small wounds or breaks in the epithelium (mucus membrane present on the inner walls of cheeks and lips). A mouth ulcer causes very difficulties for the victims to chew, eat or even drink anything. Mouth Ulcers are very sensitive due to the direct exposure of nerves in the oral cavity. The condition becomes worse if mouth ulcers are big in size or many in numbers (chronic).

Sometimes, hitting of epithelium with a hard material like a tooth brush may turn into mouth ulcers causes. So be careful while brushing up your teeth.

  4. Fasting or being hunger for the longer duration of time causes stomach ulcers as well as mouth ulcers. As our stomach keep on secreting acidic material (like HCL) and other digestive enzymes when we are hungry in order to digest the food. But if you ignore the call of hunger then these digestive enzymes and digestive juices harms the inner layer of esophagus and causing ulcers which eventually reaches the oral cavity finally results in mouth ulcers.

Major Specific Causes of Mouth Ulcers

Mouth Ulcers causes and the Physical injuries to the oral cavity

It has been seen that the minor injuries in oral cavity are the invitations for the development of bacteria and thus causing ulcers. These injuries can be caused by some sharp edged spoons, forks,edges of the tooth, biting of the inner layer while chewing or eating food. Dental braces and toothbrush may also become the reason for these minor injuries.

Injuries caused by some chemicals

Some chemicals which come in contact to our mouth becomes the cause of mouth ulcers. These chemicals include alcohol, vinegar, aspirin and especially SLS (Sodium Lauryl Sulphate) which is present in most of the toothpastes. As all of us regularly brush up our teeth and hence it has become one of the major mouth ulcers causes.

Smoking affecting epithelium

It is commonly seen that the smokers experiences ulcers within a week or two after they terminate their smoking habits. But this effect is seen to be reduced by the oral supplement of nicotine.

Ulcers due to Infection and viral

Bacteria, fungi or the viruses may also lead to mouth ulcers. This process of infection may start from the touch of your unclean hands to the chapped lips or by massaging your gums with unwashed hands. In rare cases, viral infections like chicken pox and shingles may be one of the mouth ulcers causes leading to painful and multiple vesicles which generally burst. Tuberculosis and syphilis may lead to cause bacterial mouth ulcerations. At the same time ‘Valley Fever’, ‘Cryptococcosis’ and ‘Dermatitidis’ are some common fungal causes of mouth ulcers.

Some allergens like amalgam may be the reason for oral lesions. There are some other allergies which may lead to mouth ulcers. Whereas autoimmunity may lead to autoimmune reaction to epithelium and ultimately causes mouth ulcers.

Treating mouth ulcers 

Most mouth ulcers don't require specific treatment. They usually heal naturally without treatment if they are:

• occasional 

• mild 

• do not interfere with your daily activities, such as eating 

Self-help tips

If you have a mild mouth ulcer, there are some steps you can take yourself to help your ulcer to heal more quickly:

• Use a soft toothbrush when brushing your teeth. 

• Avoid eating hard foods, such as toast, and stick to soft foods that are easier to chew. 

• Avoid eating foods that have triggered an ulcer in the past. Reduce your stress levels by doing an activity that you find relaxing, such as yoga, meditation or exercise. 

If your ulcer has a specific cause, such as a sharp tooth cutting the inside of your cheek, it will usually heal naturally once the cause has been treated. If you suspect that a sharp tooth has caused an ulcer, visit your dentist so that they can repair it.


If your ulcer is painful, your GP can prescribe a medication to help ease your symptoms.

You can also buy mouth ulcer medicines over the counter without a prescription at your local pharmacy.

Types of medicines used to treat mouth ulcers include:

Antimicrobial mouthwash

Antimicrobial mouthwash helps to kill bacteria, viruses or fungi that may cause a mouth infection if you're unable to brush your teeth properly.

Chlorhexidine gluconate is the most commonly prescribed mouthwash. You normally have to use it twice a day.

After using chorhexidine gluconate, you may notice that your teeth are covered in a brown stain. This staining is not permanent, and your teeth should return to their normal colour once you finish the treatment.

The best way to prevent staining is to brush your teeth before using chorhexidine gluconate mouthwash. However, after brushing your teeth make sure that you thoroughly rinse your mouth out with water before using the mouthwash.

Chorhexidine gluconate mouthwash should not be used to treat infants under two years old.


A corticosteroid is a type of medicine that reduces inflammation.

Mouth ulcer medications contain a low dose of corticosteroid to make the ulcer less painful. It's best to start using corticosteroid medication as soon as a mouth ulcer develops.

Hydrocortisone is the most commonly prescribed corticosteroid. It comes as a lozenge, which slowly dissolves in your mouth. You usually have to take a lozenge four times a day.

Children under 12 years old should see a GP before starting this treatment.


If your mouth ulcer is very painful, your GP may prescribe a painkiller that you can apply directly to your ulcer.

You may also find that your mouth feels numb when you first use the mouthwash. This is normal and the feeling will soon return to your mouth.

Although all these treatments reduce swelling and discomfort in mouth ulcers that are already present, they won't prevent you developing new mouth ulcers in future.
