What is a mouth ulcer? Simply put...
A mouth ulcer is a painful sore that can develop anywhere inside your mouth. They are usually red, yellow, or white in color. Sometimes there may be just one sore, or several can develop at once.
These are the places where you can get these injuries:
- In the gums
- Above or below the tongue
- Palate (top of the mouth)
- On the inside of the cheeks
- On the inside of the lips
These sores can be very painful when eating, drinking, or even speaking . Sometimes, seeing them can be a little scary. But the most important thing is that they are a sexually transmitted disease (STI - Sexually Transmitted Disease). Infection )` is not. And these are not spread by kissing or sharing food and drinks.
Most of the time, these mouth sores don't cause much harm , other than pain and discomfort. They heal on their own in a week or two. However, there are some types of mouth sores that can sometimes be a sign of another underlying condition. For example, they can be caused by certain viruses, autoimmune diseases, or gastrointestinal issues.
So, what types of mouth sores are there?
There are several types of sores and spots that can develop inside the mouth. Let's take a look at the main ones:
- Canker sores / aphthous ulcers: These are the most common type of mouth sores. Doctors are not sure exactly why they occur, or why some people get them more often. They can be caused by a minor injury (e.g. biting your cheek), acidic foods, and sometimes Stress can also cause this. Canker sores are usually white or yellow in color, with a red border around them.
- Oral lichen planus: This condition causes itchy, white, lace-like lesions inside the mouth. It is caused by an immune system reaction. It is most common in women over 50 years of age.
- Leukoplakia: This causes white or gray patches to form inside the mouth. This condition is caused by an overgrowth of cells. It can be caused by long-term exposure to things like smoking and chewing tobacco. But sometimes it can develop for no reason. Most of the time, leukoplakia patches are not cancerous.
- Erythroplakia : This is another symptom of smoking or chewing tobacco. People with erythroplakia may notice red patches inside their mouths, especially behind the bottom teeth or under the tongue. Unlike leukoplakia, erythroplakia patches are usually a precancerous condition or can be cancerous .
- Oral thrush: This fungal infection is caused by an overgrowth of a type of yeast called Candida albicans in the mouth. It usually occurs after taking antibiotics or when your immune system is weakened. It causes red and creamy white sores and patches in the mouth.
- Oral cancer: Red or white sores or patches in the mouth can also be a symptom of oral cancer. These sores do not heal on their own . If you have a sore in your mouth that has been there for more than three weeks, be sure to see a doctor.
What are the symptoms of a mouth ulcer?
It's usually easy to spot a mouth ulcer. You can see these ulcers on your gums, tongue, inside your cheeks, inside your lips, or on your roof of the mouth.
These injuries usually look like this:

- The middle is white, yellow or gray.
You may have just one sore, or you may have several. You may also have symptoms like:

Why do we get these mouth sores? What are the causes?
There can be many reasons why mouth ulcers develop. Let's take a look at what they are:
- Minor injuries to the delicate tissues of the mouth during dental procedures, such as fillings.
- Accidentally biting your cheek or tongue.
- An allergic reaction to certain types of bacteria.
- Using braces or retainers.
- Using harsh, abrasive toothpastes.
- Eating acidic foods like oranges, pineapples, and strawberries frequently.
- Hormonal changes that occur with a woman's menstrual cycle.
