Why do I keep getting sores in the inside of my mouth?


Sores in the mouth can be caused by a number of common factors, including irritation from food, drinks, or certain types of dental appliances; poor oral hygiene; or health conditions such as infections, allergies, or even immune disorders. Some of these sores can be painful, while others may remain unnoticed. In any case, it is important to address and treat the issue quickly to prevent any further discomfort or complications.

Right off the bat, it’s important to speak with a healthcare professional if the sores don’t heal or you’re experiencing severe pain or discomfort. A doctor or dentist can provide you with a thorough examination and determine why they’re occurring.

But first, let’s discuss some of the most common causes of sores in the mouth.

Irritation from Food and Drinks

If the sores are located on the outside the mouth, the culprit could be acidic or spicy foods. Even something as simple as coffee or soda can cause an inner lip to become irritated, resulting in a sore.

Poor Oral Hygiene

If you’re not brushing and flossing your teeth regularly, bacteria and plaque can build up in the mouth. This buildup can lead to infection, causing sores to appear—often in the form of canker sores.

Allergies and Immune Disorders

An allergic reaction or immune disorder, such as lichen planus, can also cause sores in the mouth. If you think this could be the case, it’s important to visit your doctor to get the right diagnosis and treatment.


Certain bacterial, viral, and fungal infections can lead to mouth sores, such as herpes and yeast infections. If a sore is particularly long-lasting or severe, it could be a sign of a more serious infection.


It may sound odd, but stress can actually contribute to the development of canker sores. For example, intense mental or physical stress can weaken the immune system, making it easier for bacteria to form.

There are many possible causes for sores in the mouth. The best thing to do is ask a professional for help in order to identify the underlying cause and receive proper treatment.

What deficiency causes mouth sores?


Mouth sores can be caused by a number of things, including an illness, injury, allergies, vitamin or mineral deficiencies, or even certain medical conditions. One common cause of mouth sores is a nutritional deficiency, particularly a deficiency in vitamins and minerals such as iron, folate, or vitamin B-12.

A deficiency in any of these essential vitamins and minerals can lead to the development of painful sores inside the mouth. Iron deficiency anemia is one condition associated with mouth sores, which can appear as either red spots in the mouth, or painful cracked lips. A lack of folate can also cause lesions, particularly at the corners of the mouth. In addition, if you have a vitamin B-12 deficiency, you may experience mouth ulcers and dryness in your tongue and throat.

If you are experiencing frequent or painful mouth sores, it’s important to talk to your doctor, who can help diagnose any underlying medical condition and provide treatment for any vitamin or mineral deficiencies. Without proper treatment, a lack of the essential vitamins and minerals that your body needs can lead to more serious health problems.

In addition to having regular conversations with your doctor, you can ensure that you maintain adequate levels of vitamins and minerals in your body by eating a balanced diet rich in fresh fruits, vegetables, whole grains and other nutrient-rich foods. Taking daily multivitamins and supplements can also help to ensure your body gets the nutrients it needs to remain healthy.

Can stress cause mouth sores?


Stress can cause a range of physical and psychological symptoms, including mouth sores. When stress is prolonged and intense, it can weaken your body’s immune system, making you more susceptible to infections. This can cause ulcers, also known as canker sores, to form in your mouth, on your tongue, inner cheeks, and on your gums.

Stress-induced mouth sores can vary in size and shape. Some may be as small as a pinhead, while others may be bigger than half an inch. They usually start out as a yellow or white spot, then turn red and may become painful and swollen.

Mouth sores can lead to additional oral health problems, such as gum and tongue infections, tooth decay, and gum disease. If you are experiencing persistent or severe mouth sores, it is important to see your dentist or primary care doctor for a proper diagnosis and treatment.

Reducing stress, eating a balanced diet, and practicing good oral hygiene are some of the best ways to prevent and treat mouth sores. Exercising regularly, getting enough sleep, limiting alcohol intake, and avoiding smoking can also help reduce the risk of developing mouth sores. Additionally, consuming nutrition rich in vitamins B12, C and folic acid, as well as zinc and iron, may help promote healing and reduce inflammation.

What autoimmune disease causes mouth ulcers?


Mouth ulcers are common and painful symptoms that can indicate an underlying autoimmune condition. One such condition is Behçet’s Syndrome, a rare form of vasculitis that is most commonly seen in young to middle-aged adults, but can affect any age group. It is characterized by recurrent mouth ulcers as well as genital ulcers and eye inflammation.

The exact cause of Behçet’s Syndrome is not known though it is thought to be related to an abnormal response of the immune system. This autoimmune condition can also cause other symptoms, including fever, joint pain and swelling, and skin rashes, as well as discomfort across many parts of the body.

Diagnosis of Behçet’s Syndrome depends on a combination of physical examination and various tests, including blood tests and other laboratory tests. Treatment will vary depending on the individual and their particular symptoms, but usually involves an immunosuppressive drug and a range of other medications to reduce inflammation and offer relief from painful symptoms.

Those with Behçet’s Syndrome should take extra care to protect themselves from infections, and may need ongoing support from a multidisciplinary team of healthcare professionals. If you have recurrent mouth ulcers that do not seem to be healing, it is important to speak to your doctor to determine the cause and receive the right treatment.

What are the 4 types of mouth sores?


Mouth sores can be uncomfortable and even painful. They can range from minor irritations to chronic issues. There are four main types of mouth sores: cold sores, canker sores, thrush and leukoplakia.

Cold sores—also known as fever blisters—are caused by the herpes simplex virus. Cold sores grow in the form of small blisters around the mouth, lips and sometimes nose area. These sores are contagious and can be spread through saliva. Treatment typically involves applying an ointment or taking an antiviral medication.

Canker sores are round or oval sores with a white or yellow center, and a red border. While they can occur anywhere inside the mouth, they are most often found on the tongue, inner cheeks, inner lips and the floor of the mouth. Canker sores can be treated with over-the-counter medications such as numbing gels, along with oral rinses, and immune boosting vitamins and minerals.

Thrush is an infection that affects the mouth and tongue, and it’s caused by a type of yeast known as Candida albicans. This yeast can cause lesions in the corners of the mouth, or produce patches on the tongue that look like white curd or cottage cheese. The best way to treat thrush is to use over-the-counter or prescription antifungal medications.

Leukoplakia is a condition where white patches form on the tongue or in the mouth. These patches can’t be scraped off, and they may increase in size over time. Leukoplakia is most common in people who use tobacco products, so quitting smoking may help reduce the risk. Additionally, topical treatments, such as corticosteroid ointments, can help reduce the discomfort.

If any of these mouth sores become persistent or severe, it’s important to seek medical attention. While they can often seem like minor issues, they could potentially be a sign of a more serious problem. A doctor can make sure that the underlying cause is identified and treated properly.

Are sores that develop in the mouth and may become cancerous?


Mouth sores that develop in the mouth can lead to a variety of different issues, and in some cases, may even become cancerous. It is important to pay attention to any sores that develop in the mouth and seek medical advice as soon as possible if they do not heal within two weeks.

There are many causes of mouth sores, including infection, injury, or certain medications. Poor oral hygiene can also contribute to their development. The most common type of mouth sores is called aphthous stomatitis, or canker sores, which usually occur on the inside of the cheeks, lips, or underneath the tongue. Canker sores are usually harmless and tend to heal within 7–10 days. However, in rare cases, they may be a sign of something more serious, such as an underlying medical condition or oral cancer.

If a person notices a sore in their mouth that does not heal within two weeks, they should contact a doctor or dentist for an evaluation. Some symptoms to look out for include sores that do not heal, sores that bleed easily, white patches on the mouth, or lumps or bumps in the mouth. These symptoms may indicate that the sore is precancerous or cancerous. If caught early, treatment can be successful in eliminating these cells before they spread further.

It is important to practice good oral hygiene and visit the dentist regularly to reduce the risk of developing mouth sores. If any sores do arise, it is essential to pay attention to them and consult with a healthcare professional if necessary.

How long should mouth sores last?


Mouth sores, also called aphthous ulcers, can be painful and uncomfortable. Fortunately, they typically go away in one to two weeks without treatment. However, if your mouth sores last longer than that, it is important to see a doctor as they could be a sign of an underlying infection or other serious condition.

To help prevent oral sores, it’s important to practice good oral hygiene. Brushing your teeth twice a day and flossing regularly will help remove food particles and plaque build-up that can cause sores. You should also avoid chewing tobacco, alcohol and spicy foods. Additionally, drink plenty of fluids, eat a balanced diet, and get adequate rest.

If you already have mouth sores, there are a few home remedies that may help relieve symptoms. Applying milk of magnesia, aloe vera, or salt water directly to the sore can provide some relief. Eating soft, cool foods can also ease irritation, as well as topical medications such as topical numbing agents and anti-inflammatory gels. Additionally, certain medications, like antihistamines and antacids, may help reduce swelling and pain.

Finally, it’s important to consult a doctor if mouth sores last longer than two weeks or if you experience severe pain. Additionally, if you have any other symptoms like fever, fatigue, or difficulty swallowing, see a doctor right away as these can indicate a more serious condition.

What do HSV mouth sores look like?


Mouth sores caused by the herpes simplex virus (HSV) can vary in appearance depending on which virus causes them, but they are often painful and may have a reddish-white center. HSV mouth sores can appear as single or multiple small blisters on the inside of the mouth, including the lips, gums, tongue, and inside of the cheeks. They usually form together in clusters, and eventually break open and form a crusty coating over the affected area. Common symptoms of HSV mouth sores include burning and tingling sensations, increased sensitivity to food and beverages, sore throat, swollen lymph nodes, and difficulty swallowing. In some cases, the sores can cause fever and difficulty eating.

Treating HSV mouth sores typically involves antiviral medications, such as acyclovir, valacyclovir, famciclovir, or Valtrex. Your doctor may also recommend over-the-counter pain relievers and anti-inflammatory medications to reduce pain and inflammation. If your HSV infection is severe or recurrent, you may need to take oral steroids. In addition to medications, lifestyle changes, such as avoiding foods and drinks that can irritate the sores, eating a healthy diet, avoiding stress, and getting plenty of rest, can help speed up healing time and prevent recurrences.

What are signs of infection in your mouth?


If you suspect that you may have an infection in your mouth, there are a few common signs and symptoms to look out for. A persistent bad taste in your mouth, discoloration of the teeth or gums, swelling of the gums, pain when chewing or swallowing, and tenderness of the area around the infected tooth are all common symptoms of an oral infection. Other signs of infection can include redness, oozing from the site of the infection, or a pus-like discharge from the area. In some cases, if the infection is severe enough, fever and swollen lymph nodes may also be present.

If you are experiencing any of these signs and symptoms, it is important to seek treatment from your dentist as soon as possible. An untreated infection can cause permanent damage to the gums, teeth and other surrounding tissues. Your dentist can diagnose and provide appropriate treatment options, such as antibiotics or a root canal procedure. Regardless of the extent of the infection, it is important to seek treatment right away in order to prevent further damage and discomfort.
