Main
- Stomatitis — inflammation of the oral mucosa: sores, redness or a coating make it difficult to eat, drink and talk.
- The causes vary: injury, infection, allergy, vitamin deficiency, reduced immunity and side effects of medicines.
- Children are affected more often, as well as people with reduced immunity and those who wear braces or dentures.
- See a doctor urgently if a child refuses to drink, a high temperature persists or the sores spread quickly.
- Examination begins with an inspection of the mouth, and if the cause is unclear, a swab, blood tests or allergy tests are prescribed.
What is stomatitis
Stomatitis is an inflammation of the oral mucosa that manifests as painful sores, redness or a coating. It can occur as a standalone problem or against the background of other diseases and usually resolves once the cause is eliminated.
What happens in the body
The oral mucosa is covered with a thin layer of cells that are the first to encounter food, microbes and accidental injuries. When this protective layer is irritated or damaged, a local inflammatory reaction is triggered in it. Immune cells rush to the site of damage and release substances that cause redness and swelling. Because of this, painful sores and a greyish or whitish coating appear on the mucosa. A person notices burning and pain when talking, chewing and swallowing. Minor injuries heal on their own, while large or multiple ones require a doctor's attention. If the irritant acts constantly, the inflammation returns again and again.
What causes it to develop
- Infections: viruses, bacteria or fungi get onto the mucosa and cause its inflammation, especially when local protection is weakened.
- Trauma to the mucosa: biting the cheek, hard food or a sharp edge of a tooth damages the lining and opens the way for irritation.
- Allergy: foods, toothpaste or hygiene products cause a reaction in which the mucosa reddens and becomes covered with sores.
- Deficiency of vitamins and minerals: a lack of nutrients weakens the mucosa, and it recovers worse after minor injuries.
- Reduced immunity: after an illness, the body's defences drop, and the oral mucosa becomes vulnerable to microbes.
- Side effect of medicines: some remedies change the condition of the mucosa, so when taking them it is important to monitor the body's reaction.
Who encounters this more often
Stomatitis occurs more often in people with reduced immunity, in children and in those who wear braces or dentures. Children put objects in their mouths and often bite their cheeks, and their defences are still developing. In adults with braces and removable dentures, the mucosa constantly rubs against the structure and is injured. People with a deficiency of vitamins and minerals notice that sores appear more often than usual and heal more slowly. After infections and with chronic diseases, the protection of the mucosa drops, so the inflammation returns. People with allergies react to foods and hygiene products, and then the redness occurs again. If sores appear regularly, it is worth discussing this with a doctor and finding out the cause.
What symptoms can occur?
Stomatitis manifests as discomfort in the mouth that worsens when eating and talking. Parents often notice that the child is fussy, refuses food or drinks less than usual.
How it is noticed at the very beginning
The first thing that catches the eye with stomatitis is that the child begins to be fussy at the table and refuses their usual food. The little one may hold the spoon for a long time, grimace at sour or hot food and ask to drink more often than usual. Sometimes they rub their cheek or lip with a hand, as if something is in the way there, and become sluggish towards the evening. Parents often put such behaviour down to tiredness after nursery or to teething. On examining the mouth, redness of the mucosa is visible, and a white or yellowish coating appears on the tongue or cheek. There may be an unpleasant odour from the mouth that does not go away after brushing the teeth. If the child refuses to drink and urinates less often than usual over a day, a visit to the doctor should not be put off.
Symptoms that occur most often
- Painful sores or erosions: small lesions on the oral mucosa that hurt when touched and make eating difficult.
- Redness and swelling of the mucosa: the tissue looks inflamed and swollen, so that any food causes irritation.
- White or yellowish coating: it covers the tongue, gums or cheeks and is not removed by an ordinary brush.
- Unpleasant odour from the mouth: it persists constantly and is noticeable even after hygiene, which embarrasses both the child and the parents.
- Increased pain from sour, spicy or hot food: usual dishes begin to sting and burn, so the child refuses to eat.
- Increased salivation: there is noticeably more saliva, it runs down the chin, and this is another reason to show the child to a doctor.
When to seek help urgently
Examinations and tests
Examination for stomatitis begins with an inspection of the oral cavity and a discussion of when the symptoms appeared. Additional tests are prescribed to rule out other conditions with similar manifestations.
How the examination begins
The first step is an inspection of the oral mucosa and an assessment of the nature of the rash, because the appearance of the changes largely determines the direction of further investigation. The doctor clarifies when the symptoms appeared, how they changed and whether they were accompanied by pain or fever. Separately, they find out what the child was ill with shortly before this and what they ate in recent days. Such information helps to link the appearance of the rash to a recent infection or to foods that may have triggered a reaction. The examination and questioning together provide the basis without which any additional tests lose their meaning. If the picture remains unclear, tests are prescribed to rule out other conditions with similar signs. Write down in advance the dates when the first rash appeared and everything that preceded it — this will noticeably simplify the conversation at the appointment.
What is prescribed and what it shows
What to prepare for the appointment
- Discharge summaries: take the conclusions from other doctors if the child has recently been treated or followed up for chronic conditions.
- Dates: write down when the first rash appeared and how it changed from day to day, including periods of improvement.
- Diet: recall and list the foods the child ate on the eve of the symptoms, including any that were new to them.
- Past illnesses: note what the child was ill with in recent weeks, even if it was a mild ailment without seeing a doctor.
- Observations: note whether the rash was accompanied by pain, fever or refusal to eat, and how long this lasted.
- Questions: formulate in advance what you want to clarify with the doctor so as not to forget anything important during the conversation.
Which doctor should I see?
Stomatitis in adults and children is most often managed by a dentist, and in young patients help is often provided by a paediatrician. Below is information on who to consult, what happens at the appointment and what care consists of.
Which specialist manages this condition
Stomatitis is a condition most often dealt with by a dentist and a paediatrician, and the choice between them depends on the patient's age and general condition. The dentist examines the oral mucosa, assesses the nature of the changes and determines whether local treatment or additional observation is needed. The paediatrician becomes involved when stomatitis develops in a child or is combined with general symptoms requiring medical assessment. If a specialist is not available nearby, one can start with a general practitioner: they will examine and refer to the right specialist. At the appointment, the doctor clarifies how long ago the changes appeared, what preceded their appearance and how the patient eats. The examination helps to understand whether the changes in the mucosa are related to local causes or to the general condition of the body. One should not delay the visit if pain makes it difficult to eat and drink or if the changes persist for a long time.
What treatment consists of
- Selection of therapy: the doctor takes into account the cause of stomatitis and the patient's general condition so that care is appropriate rather than universal.
- Pain relief and treatment of the mucosa: reducing pain and local treatment help one eat and drink calmly while the mucosa heals.
- Gentle diet: irritating foods are removed from the diet so as not to injure the mucosa and not to intensify discomfort.
- Plenty of fluids: sufficient fluid intake reduces the risk of dehydration, especially when swallowing or chewing causes pain.
- Treatment of the underlying disease: if stomatitis is related to another condition, care is also directed at it, otherwise the changes in the mucosa may return.
- Follow-up with a specialist: in severe cases the doctor schedules repeat examinations in order to notice changes in time and adjust care.
What depends on the patient themselves
Regular follow-up is the part of the result that largely rests on the patient themselves and their loved ones. If the doctor has scheduled a repeat examination, one should attend it even with noticeable improvement, because the mucosa does not heal immediately. An adult should honestly tell which foods cause pain and not try to endure it silently. It is important for parents to monitor whether the child drinks enough fluids and whether they refuse food because of pain. Notes on when the changes appeared and how they changed help the doctor assess the picture more accurately at the appointment. In severe cases, a missed examination postpones the adjustment of care and delays healing. Therefore, it is reasonable to clarify in advance when to come again and to keep to that date.
What helps prevent an exacerbation?
Everyday oral care and attention to the general state of the body help prevent an exacerbation of stomatitis. Below are the habits, observations and check-up intervals that reduce the risk of painful areas reappearing.
What to change in your habits
Brushing your teeth daily with a soft brush reduces irritation of the mucosa and removes food debris that keeps inflammation going. Coarse and spicy food, hot drinks and acidic foods injure already sensitive areas, so it is better to limit them while they heal. A sufficient intake of vitamins from ordinary food supports tissue repair and reduces the likelihood of new damage. If you are prone to allergic reactions, it is worth noticing in advance after which foods or products redness and burning appear. Chronic diseases, whether digestive disorders or endocrine conditions, weaken the protection of the mucosa and make exacerbations more frequent. Observing your own condition helps link the appearance of ulcers to a specific food, toothpaste or stress. If irritation recurs after the same food, it is reasonable to remove it from your diet and discuss this with a doctor at an appointment.
What to keep under control
- Condition of the mucosa: examine your mouth while brushing to notice redness or an ulcer at the very beginning, when it heals faster.
- Brush hardness: soft bristles do not injure the gums and the inner surface of the cheeks, whereas hard ones leave microcracks.
- Diet: make sure your diet has enough vitamins from vegetables, fruit and grains, and that coarse and irritating dishes appear rarely.
- Chronic diseases: keep the conditions you already have under observation, because their exacerbation often brings problems in the mouth with it.
- Reactions to allergens: remember what triggers itching or swelling, and try to avoid those foods and hygiene products.
How often to see a doctor
A regular check-up with a dentist is needed even when nothing in the mouth bothers you and you feel well. The doctor notices changes in the mucosa earlier than they become painful and assesses how previous areas are healing. If exacerbations are frequent, you should come for a check-up more often than in isolated cases, so as to have time to understand the causes. If ulcers appear after food, stress or against the background of a chronic disease, this should be mentioned at the appointment. The dentist may refer you to another specialist when they see a link between the condition of the oral cavity and your general health. Keeping simple notes about when and after what changes appeared makes the conversation with the doctor specific. Such monitoring does not replace the prescribed treatment, but it helps to notice trouble in time and not let it progress.
What is worth remembering
Stomatitis almost always resolves on its own, but that does not mean it can be ignored. Below are brief conclusions that help you make a calm and correct decision.
Key conclusions
Stomatitis is a condition in which what matters is not so much the name as the cause and how often it recurs. In one person, mouth ulcers appear once after an accidental injury to the cheek, while in another they appear again and again with no apparent cause. A one-off episode usually heals within a short time and requires no special measures other than gentle food and hygiene. But if stomatitis keeps coming back, drags on longer than usual, or makes it hard to eat and drink, a visit to the doctor should not be put off. The doctor looks not at a single ulcer but at the overall picture: how often it happens, what precedes it, how the person eats and what illnesses they have. The reader's task is not to look for the cause on their own, but to honestly describe it at the appointment. Then the decision will be based on facts, not on guesses and random advice.
