Palate sores and palate pain are mostly caused by burns from hot food, irritation from hard foods, canker sores or infections inside the mouth. An infection spreading from the upper teeth can also create a painful swelling on the palate. Small, superficial sores usually heal within one or two weeks.
What helps a palate sore? Rinsing gently with warm salt water, eating cool and soft foods and avoiding irritating foods can bring relief. However, if there is rapidly growing swelling, fever, difficulty swallowing or a sore that does not improve within two weeks, a dental assessment is needed.
What Is a Palate Sore?
The palate is the tissue that forms the roof of the mouth. The hard palate at the front has bone support. The back part, close to the throat, is called the soft palate.
A sore on the palate can appear as a loss of surface tissue, peeling, redness or a small ulcer with a white-yellow center. The location, appearance and duration of the sore and the symptoms that come with it help to identify the likely cause.
Not every case of palate pain comes with a visible sore. In conditions such as a dental infection, dry mouth or burning mouth syndrome, pain can be felt even though the tissue looks normal.
What Are the Signs of Palate Sores and Palate Pain?
The signs vary with the cause of the sore. Pain can increase with hot and spicy foods. In some people, tingling or a burning feeling comes first.
- A white, yellow or red sore on the palate
- Pain while eating, drinking or swallowing
- Tenderness to touch and peeling of the surface
- Swelling of the palate or fluid-filled blisters
- Dry mouth, a change in taste or a bad taste
- Throbbing in the upper teeth or tenderness when chewing
- Fever, tiredness or tender glands in the neck
| Finding | Possible Cause | Distinguishing Clue | What to Do |
|---|---|---|---|
| A superficial, oval and painful sore | Canker sore or irritation | A white-yellow center with a red border may be seen | Reduce the irritation and follow the healing time |
| Peeling after hot food | Heat burn | The complaint starts right after contact with hot food | Keep the area cool and avoid hot foods |
| Throbbing swelling near an upper tooth | Infection from a tooth | Toothache, tenderness when chewing or a bad taste may come with it | Contact a dentist the same day |
| White layers that turn red when wiped | Possible oral thrush | Widespread burning and a change in taste may be present | Get an examination for a diagnosis and suitable treatment |
| Constant burning with no visible sore | Burning mouth syndrome or dry mouth | A change in taste and complaints that increase during the day may be seen | Get an assessment from a dentist and, if needed, a doctor |
| An area that does not heal, is firm or bleeds | An oral lesion that needs investigation | No clear improvement is seen within two weeks | Do not put off an examination |
Why Do Sores Form on the Palate?
Hot Foods and Drinks
Very hot pizza, soup, tea or coffee can burn the surface of the palate. First there may be burning and redness, then a whitish layer or peeling. Repeated contact can delay healing.
Hard Foods and Mechanical Irritation
Hard bread crusts, chips, a piece of bone or sharp foods can scratch the palate tissue. Ill-fitting dentures and sharp surfaces in the mouth can also irritate the same area constantly.
Canker Sores
A canker sore is a painful, non-contagious mouth sore. It is usually seen on the movable tissues of the mouth, including the soft palate. Stress, minor trauma and some nutritional deficiencies may be linked to recurrent canker sores.
Frequently recurring or numerous canker sores can occur along with deficiencies of iron, folate and B vitamins or with some systemic diseases. In that case, focusing on the sore alone may not be enough.
Infections
Viral infections can create many blisters or sores inside the mouth. Fever and general tiredness may come with them. In oral thrush, there may be redness, burning and white layers that leave a tender surface when wiped.
It is not always possible to tell the type of infection from the appearance alone. An examination is especially important for people with a disease or treatment that suppresses the immune system.
Tooth and Gum Infections
An infection developing around the root of an upper tooth can cause swelling toward the palate. In this case, palate pain may come with throbbing in the tooth, tenderness when chewing, a bad taste or facial swelling.
Even if a tooth abscess drains on its own, the source of the infection has not been removed. Piercing or squeezing the swelling can spread the infection into the surrounding tissues.
Dry Mouth and Irritating Products
Saliva protects the oral tissues and keeps them moist. Dry mouth can make the palate more open to friction and irritation. Mouthwashes containing alcohol, tobacco products and very acidic foods can increase the complaint.
Nutritional Deficiencies and Systemic Diseases
Recurrent mouth sores may be linked to some nutritional deficiencies. Celiac disease, inflammatory bowel diseases and immune system problems can also occur together with mouth sores.
If the sores come with skin or genital sores, joint swelling, digestive complaints or unexplained weight loss, a medical assessment is needed.
What Helps a Palate Sore?
With a palate sore, the aim is to reduce irritation while it heals and to keep up oral care. Home care can be supportive for superficial, mild sores. If there is an infection or another disease, treatment aimed at the cause is needed.
- Rinse your mouth gently with warm salt water and do not swallow the liquid.
- Choose soft foods such as yogurt, purée and warm soup.
- Stay away from very hot, spicy, sour, hard and sharp-edged foods.
- Drink enough water and avoid habits that can increase dry mouth.
- Keep up oral care with a soft-bristled toothbrush.
- Do not use oral care products containing alcohol, or tobacco products.
Do not apply baking soda, cologne, garlic or crushed medicines directly to the sore. These methods can irritate the tissue and can change the appearance of the sore, making assessment harder.
What Helps Palate Pain?
The approach that helps palate pain depends on the source of the pain. With a fresh burn, drinking cool water and avoiding hot foods can be soothing. Pressing ice directly on the sore for a long time can cause extra irritation.
If the pain comes with throbbing in the upper teeth, marked swelling of the palate or a bad taste, home care is not enough. An infection coming from a tooth needs to be assessed without delay.
Do not take medicines at random to control pain. If a medicine or oral care product suited to your health is needed, it should be decided by a dentist or a doctor.
What Causes Swelling of the Palate?
Swelling of the palate can develop from trauma, a burn, an infection, an allergic reaction or an abscess from an upper tooth. How firm the swelling is, where it is, how fast it grows and whether it is painful all matter in the assessment.
A painful, throbbing local swelling can suggest an infection, especially if there is a problem with a nearby upper tooth. Do not try to burst the swelling, pierce it with a needle or squeeze it out.
If the swelling started suddenly and comes with swelling of the lip or tongue, an allergic reaction may be involved. If there is difficulty breathing or swallowing, call 112 (the emergency number in Turkey) or go to an emergency department.
What Causes Burning of the Palate?
Burning of the palate can develop for a short time after contact with hot food. Burning that lasts for weeks with no visible sore may be linked to dry mouth, a fungal infection, reflux or nutritional deficiencies.
In burning mouth syndrome, repeated burning can be felt on the palate, tongue or lips. An oral examination may not show a clear sore. A change in taste, tingling and dry mouth can come with the complaint.
For long-lasting burning of the palate, the teeth and oral tissues are assessed first. If needed, blood tests, an oral swab, an assessment of saliva or an opinion from the relevant medical fields may be requested.
When Should You See a Dentist?
Most small sores heal quickly. On the other hand, some findings can show that an infection is spreading or that the sore needs a detailed examination.
Signs That Need Urgent Assessment
- Difficulty breathing or swallowing
- Rapidly growing swelling of the mouth, face or neck
- Swelling of the palate or face together with fever
- Marked difficulty opening the mouth
- Severe pain that prevents you from drinking
Situations That Need an Examination Appointment
- A sore that does not clearly get smaller within two weeks or lasts longer than three weeks
- Frequently recurring, large or numerous palate sores
- An area that bleeds easily, becomes firm or has irregular edges
- A red or white patch that does not wipe away
- Numbness in the mouth, unexplained weight loss or swelling in the neck
- A sharp tooth or denture that keeps injuring the same area
Having these findings does not on its own mean a serious disease. Even so, it is important for oral lesions that do not heal to be seen by a dentist.
How Are Palate Sores Diagnosed and Treated?
The dentist asks when the sore started, whether it recurs and whether there has been recent contact with hot food. Along with the palate, the teeth, gums, tongue and other oral tissues are examined.
During assessment in our clinic, pain in the upper teeth, tenderness when chewing and how fast the swelling is growing are asked about in particular. If an infection from a tooth is suspected, a radiographic examination may be needed.
For recurrent sores, blood tests or an assessment by the relevant clinician may be requested. If a fungal infection is suspected, a swab can be taken. For lesions that do not heal or look suspicious, a biopsy and a specialist opinion may come onto the agenda.
Treatment is planned according to the cause. In a traumatic sore, the source of irritation is corrected. For canker sores, products aimed at reducing pain and the inflammatory response can be used after a clinical assessment.
Fungal or viral infections may need prescription treatment aimed at the cause. With a tooth abscess, root canal treatment, draining the infection or tooth extraction are considered according to the examination findings.
Antibiotics are not needed for every swelling of the palate. Whether they are needed is decided by a clinician according to the spread of the infection and the general symptoms. Antibiotics should be used only with a prescription.
How Can Palate Sores Be Prevented?
- Check the temperature of food and drinks before you consume them.
- Chew hard and sharp foods slowly.
- Clean your teeth with a soft-bristled brush, without pressing hard.
- Have ill-fitting dentures and sharp tooth edges checked.
- Avoid tobacco products and mouthwashes containing alcohol.
- For recurrent sores, note your diet, stress and sleep pattern.
- If you have dry mouth, drink enough water and ask for the cause to be assessed.
Keeping track of how the palate sore looks and when it started can be useful during the examination. For sores that recur often, the underlying cause should be investigated rather than relying on home care alone.
Frequently Asked Questions
How long does a palate sore take to heal?
Small canker sores and superficial irritation usually heal within one or two weeks. If there is no clear improvement within two weeks, or the sore lasts longer than three weeks, see a dentist.
Does salt water help a palate sore?
Rinsing gently with warm salt water can support oral hygiene and reduce irritation. However, it does not remove the cause of a tooth abscess, a fungal infection or constantly recurring sores.
Is swelling of the palate dangerous?
Not every swelling is dangerous, but swelling that grows quickly or comes with fever can be a sign of infection. If there is difficulty breathing or swallowing, seek emergency help.
Can palate pain come from a tooth?
Yes. An infection developing around the root of an upper tooth can cause pain and local swelling on the palate. If there is toothache or tenderness when chewing, do not delay the examination.
What causes burning of the palate with no visible sore?
Dry mouth, a fungal infection, reflux, some nutritional deficiencies or burning mouth syndrome can cause this complaint. Long-lasting burning needs an assessment by a dentist and, if necessary, a doctor.
Should a swelling on the palate be burst?
No. Piercing or squeezing the swelling can spread the infection into the surrounding tissues and damage the oral tissue. The source of the swelling should be assessed by a dentist.
Are palate sores contagious?
Canker sores and sores caused by trauma are not contagious. However, some viral infections can spread; if there are many blisters, fever or general tiredness, you should be examined.
