Mouth Ulcers Definition and Meaning

Abnormal changes and changes that deviate from healthy anatomy can develop in a wide variety of organs and tissues in the human body. This also applies to unpleasant mouth ulcers.

What are mouth ulcers?

Mouth ulcers come in different forms. The mouth ulcers can be harmless in nature or become a serious disease.

An ulcer in the mouth is a health condition that is also known as an ulcer in medicine. In the case of an ulcer in the mouth, deep layers of the mucous membrane are attacked and the affected cell and tissue areas are damaged.

For this reason, ulcers in the mouth are quite easy to see. Some mouth ulcers can heal as a result of specific treatment, while other forms recur or leave drastic scars.


As with other ulcers, in addition to impaired blood flow, triggers such as infections by viruses, bacteria or fungi as well as tumors can also be considered as causes for ulcers in the mouth.

Mechanical effects such as pressure or friction as well as metabolic disorders or impaired cell growth are possible causes for this.

The external influences that lead to the development of tumor-like ulcers in the mouth include excessive smoking and increased consumption of alcohol. Incorrectly fitting dentures and careless hygiene of the mouth can also cause an ulcer in the mouth.

So-called canker sores are very painful and can develop as ulcers in the mouth due to physical and psychological stress and a weakened immune system. Various additives in food can also cause mouth ulcers.

Symptoms, ailments & signs

Mouth ulcers are primarily noticeable as small, sore spots in the mouth. These areas are usually swollen and painful to the touch. The ulcers themselves are reddish or white, with a dark red border, and a few millimeters to a few centimeters in size. They occur individually or in groups of several canker sores, with serious underlying diseases large parts of the oral cavity are affected.

In individual cases, bleeding or inflammation occurs. Itching and burning are also typical symptoms of ulcers. Those affected find the canker sores extremely uncomfortable and often have problems eating or speaking. Ulcers appear on the gums, the inside of the cheeks, or the inside of the lips.

They usually develop overnight and resolve on their own after a few days to weeks. In severe cases, the growths can affect the strength of the gums and teeth. This can lead to damage to teeth and gums and, in the worst case, to the loss of one or more teeth. If the person concerned wears braces or dentures, painful ingrowths can occur. Displacements and damage to the jawbone cannot be ruled out.

Diagnosis & course

The first thing you notice about mouth ulcers is that they are painful and cause a discomfort to the tongue. Some mouth ulcers can also give off unpleasant smelling secretions that can be perceived as bad breath.

In the case of mouth ulcers, the severity of the abnormalities can impair speaking and eating. A medical examination provides reliable diagnoses even if the smallest ulcers appear in the mouth. As a rule, the specialist scans the affected regions and examines them.

In order to obtain a corresponding meaningful result, microscopic examinations in the laboratory are requested. A smear is taken for this purpose. In the case of an ulcer in the mouth with a suspected oral cancer, a sample of the tissue is useful. Doing various blood tests for an ulcer in the mouth can also help.


Mouth ulcers are inflammations of the lining of the mouth that can cause various complications. Affected people who suffer from an ulcer in the mouth should therefore consult a doctor at an early stage. Only through timely treatment can serious consequences be avoided. An ulcer causes severe pain and also makes it difficult to eat.

Such an ulcer in the mouth is usually due to poor oral hygiene. So if you already suffer from an ulcer in the mouth and want to avoid further complications, you should observe strict oral hygiene. If the affected person notices an enlargement of the ulcer within a short time, a doctor should be consulted immediately.

Rapid improvement can only be achieved with appropriate medication that effectively relieves the inflammation. Under certain circumstances, an ulcer in the mouth can also develop into an abscess. An abscess is a cavity that is filled with pus fluid. Such an abscess should always be treated by a professional.

If you forego medical treatment at this point, you run a great risk. An abscess can build up internal pressure so that the bacteria in it can enter the bloodstream. In such a case there is even a danger of dangerous blood poisoning. If you want to avoid this, you shouldn’t wait too long before visiting the doctor.

When should you go to the doctor?

If there are unusual growths in the mouth, a doctor should always be consulted. If there is pain, open wounds or an uncomfortable feeling of tightness in the mouth, a doctor is needed. If the person concerned wears a fixed or flexible denture, it is advisable to see the irregularity to a doctor in order to clarify and prevent further complications.

If there is bleeding from the gums or tongue, medical treatment is necessary. A doctor should also be consulted in the event of a general feeling of illness, inner restlessness, irritability or complaints such as malaise or increased body temperature. If the ulcers spread or increase in size in the mouth, a doctor will be needed. If the changes in the mouth lead to complications during the daily cleaning of the mouth, a check-up visit with a doctor should take place.

If a headache occurs, a feeling of pressure in the mouth is perceived or the teeth are shifted, a doctor must be consulted. A doctor’s visit is required in the event of impaired sound production or refusal to eat. The person concerned is threatened with an eating disorder and an undersupply of the organism, which has far-reaching consequences. If you have an unusual bad breath, pus formation in the mouth or a strange taste in the mouth, consult a doctor to clarify the symptoms and treat the cause.

Treatment & Therapy

The treatment of mouth ulcers always depends on the results of the diagnostic tests and can be more or less extensive. Holistic therapy may be needed for some types of mouth ulcers.

This is common with syphilis or leukemia, for example. If it is a fungal infection of the oral mucosa that leads to mouth ulcers due to thrush, various therapies are possible. If mouth ulcers are found to have resulted from mechanical irritation, the foreign bodies or teeth should be thoroughly examined and the cause eliminated.

The physical triggers for the formation of ulcers in the mouth are thereby eliminated and healing can take place. A variety of mouth ulcers can also be caused by medication or a reduced immune system. If you have diabetes mellitus, it is advisable to avoid mouth ulcers by ensuring that your blood sugar levels are optimally controlled.

This is the only way to prevent circulatory disorders that lead to mouth ulcers. For some mouth ulcers, medically sound oral care with special rinses can help improve the chances of recovery. Often, mouth ulcers are the cause of chronic digestive disorders.

Outlook & forecast

In the case of an ulcer in the mouth, the doctor also speaks of oral cancer. The prognosis for an ulcer in the mouth is not very good. Only 50 to 60 percent of those affected survive this disease. The explicit prognosis depends heavily on when the mouth ulcer is recognized or diagnosed. If the cancer is detected at an early stage, appropriate treatment with the right medication can be initiated. For this reason, a doctor should be consulted even with the smallest changes in the oral cavity.

If this clinical picture remains completely without medical treatment, then there is an acute danger to life. The cancer forms metastases that can spread throughout the mouth. The chance of survival drops considerably in such a case, so that it is only 10 to 20 percent. For this reason, medical and drug treatment is essential for an ulcer in the mouth.


Almost everyone has had mouth ulcers from a painful viral infection or other causes. Adequate oral hygiene should be given as a preventive measure to avoid mouth ulcers. In addition, general health care will also help prevent mouth ulcers from occurring. This also includes the treatment of previous causal diseases.


Mouth ulcers should primarily be examined and treated by a doctor. Only through early detection and subsequent treatment of these complaints can further complications be avoided. The measures or options for aftercare depend very much on the success of the treatment and also on the cause of the mouth ulcers.

As a rule, even after a successful examination and removal of the mouth ulcers, regular examinations should be carried out by a doctor in order to detect and remove new ulcers at an early stage. In most cases, the ulcers are removed with the help of a surgical procedure. Afterwards, the person affected should recover and take care of their body.

Exertion or physical activity should be avoided in order not to slow down the healing process. In many cases, increased standards of oral hygiene may also be necessary to completely remove mouth ulcers. It is advisable to seek advice from a dentist on how to properly remove and treat the mouth ulcers. It cannot generally be predicted whether the disease will lead to a reduced life expectancy for the person affected.

You can do that yourself

In the case of recurring ulcers in the mouth – in addition to self-treatment – the cause of the occurrence of these tissue changes should be examined by a specialist.

The treatment can be very well supported by measures that you can carry out yourself. It is important to achieve an anti-inflammatory, antibacterial and decongestant effect. This can be done by rinsing the mouth every day.

Ready-made mouthwashes are available from pharmacies and drugstores. You can also make your own solutions with plant extracts. Nature offers a variety of medicinal plants. These include primarily: chamomile, sage, nettle or mallow. These are available as tea or powder. Dabbing with pure lemon juice is also recommended.

Since ulcers in the mouth are mostly associated with damaged intestinal flora – they often occur after virus infections or fungal infections – it is also important to clean the intestine. With ready-made preparations – for example made from beetroot and psyllium husks – the intestine can be cleaned and then rebuilt with healthy intestinal bacteria by taking probiotics.

The use of coconut oil has proven effective against fungal attack – which is also evident in the mouth through tongue coatings. Traditional oil pulling with this or any other virgin oil can speed up the healing process. Basically, good oral hygiene should be observed. This can prevent a new ulcer.
