Mouth ulcers: Causes, prevention, and remedies
Mouth ulcers are painful lesions that can appear on the soft tissues of the mouth, including the gums, cheeks, tongue, and roof of the mouth. These ulcers can be triggered by various factors such as stress, gastrointestinal issues, or tissue injury.

Often, mouth ulcers are accompanied by a burning sensation or tingling. Severe ulcers may cause swollen lymph nodes, fever, body aches, and fatigue.

Common causes include accidental biting, hot food consumption, stress, and tissue trauma from braces or dentures, requiring proper care and treatment.

Discomfort while eating or drinking is typical with mouth ulcers. Mild cases can often be managed at home using saline rinses and baking soda applied as remedies.

Types of mouth ulcers that need attention
There are primarily two categories:

Simple ulcers, or canker sores, tend to recur 3-4 times annually, lasting about a week. They are common among adolescents and young adults, appearing as pale grey centers surrounded by red borders.

These ulcers are non-contagious.

Cold sores or complex ulcers are contagious and often require specific treatment. These are linked to stress and immune suppression, with a higher chance of recurrence in individuals with a history of mouth sores.

Causes of simple canker sores:

Medications taken during viral illnesses may contribute.

Trauma caused by dental appliances like braces or dentures.

Sensitivity to acidic foods can trigger these sores.

Lack of Vitamin B12 increases susceptibility.

Sulfates in toothpaste and mouthwash may play a role.

Factors leading to cold sores or complex ulcers and treatment options:

Stress is a significant trigger.

A weakened immune system increases risk.

Deficiencies in zinc or Vitamin B12 are common contributors.

Underlying gastrointestinal conditions such as Crohn’s or celiac disease also elevate risk.

Approaches for mouth sore management:

Most minor ulcers resolve within days, with pain relief.

Saline rinses and baking soda applications can alleviate discomfort.

Laser treatments can provide quick relief for persistent sores.

Avoiding hot, spicy, or acidic foods helps prevent aggravation.

If sores are large or persist beyond three weeks, consult a healthcare professional.

Seek medical advice if drinking fluids becomes difficult due to pain.

Preventative tips for mouth ulcers:

While no method guarantees prevention, reducing intake of irritating foods can help.

Steer clear of citric, spicy, and hot foods known to cause irritation.

Avoid chewing gum to reduce accidental cheek bites which may lead to sores.

Practice good oral hygiene with soft-bristled brushes and regular flossing to lower risk.
