Canker sores on the gums: Causes, prevention and effective treatments

gum ulcer

Small ulcerations sometimes form in different places in the oral cavity , including the gums. Called canker sores , oral ulcers or even aphthous stomatitis , these lesions are a real source of embarrassment. 😖

They are likely to affect a patient's quality of life. We must therefore raise awareness among a large number of people about this to help the vast majority to contain them. Here are the causes, preventions and effective treatments for canker sores .

Understanding canker sores

To be able to stem the threat of canker sores, it is essential to better understand it. This involves knowing its manifestations and being able to differentiate it from related conditions.

Definition and description of canker sores

Canker sores are superficial, painful ulcers that can form on the gums or other places in the oral cavity. Often small, these conditions can reach several millimeters in diameter. 😨

Common to all canker sores, common symptoms include:

Difference between canker sores and other mouth sores (like herpes)

Canker sores are sometimes confused with other oral pathologies , notably herpes . 😷 Although both diseases affect the oral environment, they have notable differences.

A canker sore usually presents as an ulcer or shallow sore. It forms on different areas of the oral mucosa, including the gums, tongue, cheeks, palate or lips.

Oral herpes appears as blisters filled with clear fluid . It usually appears on the lips, corners or around the mouth. 👄

Common causes of canker sores on the gums

A canker sore can be triggered by different factors. Injury or trauma to the gums are common causes. This can include brushing too vigorously, accidental biting, dental procedures, etc.

Some patients are found to be susceptible to mouth ulcers due to their hormonal fluctuations. This is particularly the case for certain women, in whom this problem occurs at the same time as menstruation, or during pregnancy. 🤰

Symptoms of canker sores on the gums

The appearance of aphthous stomatitis on the gums can result in different symptoms . While some of these signs are clearly visible, others are underlying and may suggest related pathologies.

Visible signs of a canker sore on the gums

The appearance of an ulcerative lesion is the most visible sign of aphthous ulcer. Round or oval in shape, it is recognizable by the presence of a wound in the gum mucosa.

This is usually accompanied by pain , sometimes mixed with a burning sensation. 🔥 Canker sores can appear individually or in groups.

Sensations and discomfort related to this condition

In patients with canker sores, the affected part of the gum becomes sensitive to touch . Even contact with food while chewing is likely to cause excruciating pain.

Canker sores on the gums can make speaking difficult . 🤭

This happens when the ulcers come into regular contact with the tongue or lips while you are speaking. The presence of a canker sore on the gum can cause a constant feeling of irritation or discomfort in the mouth , which can be distracting and impair overall well-being.

Usual duration of a canker sore

The typical duration of a canker sore can vary from person to person. Most of the time, mouth ulcers take about one to two weeks to heal completely. During this period, you may notice an evolution of aphthous stomatitis, going through different phases. ☝️

After this time, the pathology begins to gradually heal. Pain and discomfort decrease and the ulcer lesion heals. The canker sore heals completely, often leaving a small area of ​​scar tissue that disappears over time. If this illness persists for an abnormally long period or if it worsens, contact a medical professional immediately. In the absence of a dentist, you can consult a general practitioner for an appropriate examination and advice.

Diagnosis and treatment

How are mouth ulcers on the gums diagnosed?

Establishing a diagnosis is the skill of a healthcare professional, such as a dentist or general practitioner . The professional carefully examines the gums and oral cavity to identify lesions characteristic of canker sores. 🩺

When the diagnosis is unclear or in the presence of recurrent mouth ulcers , additional tests may be requested. This often includes tissue samples for laboratory analysis. The aim is to exclude the possibility that there are underlying pathologies and to confirm the diagnosis .

Conventional treatments available

There are several conventional treatments to relieve the symptoms of canker sores on the gums, including topical medications . This includes products such as gels or ointments containing topical pain relievers. 💊

Some products contain protective or adhesive agents , which form a protective barrier on the canker sore, facilitating its healing. You can also use a mouthwash containing antiseptics to reduce bacterial growth in the mouth and optimize the healing of canker sores. One of the best known is Filmogel from the Urgo brand!

Natural and home remedies

To relieve the symptoms of canker sores, patients also have the choice between several natural and home remedies . Although they do not necessarily cure canker sores, they help speed up the healing process and relieve discomfort. 🙏

Among the grandmother's recipes that can relieve this pathology, you will find the famous mouthwash based on baking soda. Mouth rinsing with salt water also appears to be an effective solution for eliminating bacteria from the infected area . 🦠

Prevention of canker sores on the gums

Eating habits to adopt and avoid

To prevent or reduce episodes of canker sores on the gums, adopt a balanced diet . Eat enough fruits, vegetables and whole grains. 🍌 Consuming foods rich in lean protein and dairy products can help strengthen the immune system and promote good oral health .

Banish tobacco from your routine. 🚬 Tobacco consumption can irritate the oral mucosa and increase the risk of developing canker sores and other oral problems.

Good oral hygiene practices

Good oral hygiene can help prevent gum ulcers. To do this, brush your teeth regularly using a toothbrush and quality toothpaste.

Today, the only quality toothbrushes recommended by dentists are electric sonic models.

Poor oral habits can easily lead to gum recession. By this we mean occasional or excessive tooth brushing. This also results in the consumption of foods that can cause a problem of hypersensitivity in the teeth. This causes dental plaque to form. In the absence of adequate treatment, it turns into tartar by feeding on bacteria present in the mouth. 😷 These are the prerequisites for dental caries and gum recession . Many other factors such as smoking can lead to gum recession.

Importance of regular check-ups at the dentist

Regular check-ups with the dentist are crucially important for maintaining good oral health and preventing dental problems. During check-ups , the professional performs a thorough examination of your mouth to detect early signs of oral problems such as cavities , infections, gum inflammation and lesions. 💥

With early detection , it is possible to intervene quickly and treat problems before they become serious. The dentist can provide you with personalized advice on your oral hygiene, including the best way to brush your teeth, floss and take care of your teeth.
