Hello, this is Lucid Dental Clinic.

Have you ever experienced a tingling feeling inside your mouth, or discomfort every time you ate?

That is oral ulcers.

Oral ulcers are a very common condition, but because the causes are so varied and recurrence is easy, many people struggle with them.

In particular, when you are under a lot of stress in a busy daily life or when you are lacking nutrition, they can occur more often.

In this article, we will take a detailed look at everything from the definition of oral ulcers to prevention methods, which are things we often explain at the Eonju Station dental clinic.

What are oral ulcers?

Oral ulcers refer to a condition in which inflammation develops on the mucous membrane inside the mouth.

Usually, white, round ulcers appear, and they can cause pain when eating or speaking, making daily life uncomfortable.

Oral ulcers usually heal on their own within 1 to 2 weeks, but if the symptoms are severe or occur frequently, care from a dental clinic or hospital is necessary.

At the Eonju Station dental clinic, we diagnose and treat a wide range of cases, from simple oral ulcers to recurrent aphthous ulcers and viral oral ulcers.

In particular, identifying the exact cause is the key to a faster recovery.

Let's look at the various causes of oral ulcers.

Oral ulcers can develop for a variety of reasons. Here are some of the most common causes.

▪Weakened immunity

When immunity drops due to stress, fatigue, lack of sleep, and other factors, oral ulcers can easily develop.

▪Nutritional deficiency

In particular, deficiencies in vitamin B, iron, and folic acid can make oral ulcers more likely to occur.

▪Mechanical irritation

Inflammation can occur when the inside of the mouth is scratched or irritated by a toothbrush, hard foods, dentures, or orthodontic appliances.

▪Hormonal changes

In women, oral ulcers may develop during hormonal changes such as the menstrual cycle or pregnancy.

▪Viral and bacterial infections

They can also be caused by infections such as herpes simplex virus or bacteria.

At the Eonju Station dental clinic, careful consultation and oral examination are used to identify the cause of oral ulcers and suggest an appropriate treatment direction.

It is important not only to apply ointment, but also to manage the condition to prevent recurrence.

Types and characteristics of oral ulcers

Oral ulcers are divided into several types depending on the cause and presentation.

The main types are as follows.

▪Aphthous ulcers

The most common type, small round ulcers appear and the pain is severe. They usually improve naturally after about 7 to 10 days.

▪Herpetic ulcers

These are caused by the herpes simplex virus, and blisters may appear along with a high fever. They mainly occur in children, but they sometimes appear in adults as well.

▪Candidal ulcers

These occur due to a fungal infection, and the tongue or mucous membrane turns white, which is a distinctive feature. They often appear after taking antibiotics or when immunity is low,

▪Necrotizing ulcerative ulcers

This is a severe form with intense pain and swollen gums, and prompt treatment is needed.

Because the treatment method changes depending on the type of oral ulcer, if symptoms recur or the pain is severe, medical care from a facility like the Eonju Station dental clinic is necessary. .

How can you prevent oral ulcers in daily life?

Prevention is far more important than treatment for oral ulcers. Just following a few simple habits that you can practice in everyday life can go a long way toward preventing them.

▪Balanced meals

It is important to eat foods rich in vitamins and iron.

▪Enough sleep and stress management

A regular lifestyle is needed to maintain immunity.

▪Keep your mouth clean

In addition to brushing, using a tongue cleaner and mouthwash is also helpful.

▪Regular dental checkups

To remove tartar and check for injuries inside the mouth, it is a good idea to visit the Eonju Station dental clinic once every 6 months.

In particular, people with weak gums or those using orthodontic appliances may develop oral ulcers more often, so it is a good idea to regularly check oral health at the Eonju Station dental clinic.

When your mouth feels uncomfortable, eating and talking become difficult. Oral ulcers are a common condition, but if they recur, they can greatly reduce quality of life. That is why it is most important to maintain healthy lifestyle habits, and, when necessary, seek a place like Eonju Station dental clinic that can provide professional diagnosis and receive early treatment.
