Burning Mouth Syndrome

Burning Mouth Syndrome – Causes, Symptoms, and Treatment Options

A persistent burning sensation in the mouth can be unsettling, especially when there are no obvious signs of irritation. This condition, often referred to as burning mouth syndrome (BMS), can affect different areas including the tongue, palate, gums, lips, cheeks, or sometimes the entire mouth. Many patients describe it as though they have scalded their mouth with hot liquid, even though no injury is visible.

BMS is known for being unpredictable. The pain can begin suddenly or develop gradually, and for some people it persists for months or even years. While treatment can be challenging, professional dental care can help uncover possible causes and provide relief strategies. At Thousand Smiles, our dental team takes a comprehensive approach to diagnosing and managing this condition. If you have been struggling with unexplained burning or discomfort in your mouth, booking an appointment with us is the first step toward relief.

Recognising the Symptoms

The way burning mouth syndrome presents itself can vary. Some of the most commonly reported symptoms include:

  • An ongoing burning or scalding feeling on the tongue, lips, or other oral tissues
  • Dryness or excessive thirst despite normal fluid intake
  • A bitter, metallic, or altered taste in the mouth
  • Tingling, stinging, or numb sensations
  • Loss of taste or changes in how flavours are perceived

The discomfort may appear in different patterns:

  • Some patients notice mild irritation in the morning that worsens throughout the day
  • Others experience pain that starts immediately upon waking and persists until bedtime
  • In certain cases, the symptoms fluctuate, disappearing for short periods before returning

Eating or drinking may temporarily reduce the burning sensation, and in most instances, no visible changes are detected in the oral tissues.

When to Seek Professional Help

Occasional irritation after consuming spicy foods or hot drinks is common. However, if you experience ongoing burning without an obvious trigger, it is important to consult a dentist or healthcare provider. A thorough evaluation can help rule out underlying medical conditions and guide treatment.

Our dentists work in collaboration with general practitioners and other specialists when necessary, ensuring that you receive a tailored plan based on your specific situation.

Possible Causes of Burning Mouth Syndrome

BMS is often classified into two main categories:

1. Primary BMS

This occurs when no clear clinical or laboratory abnormalities are found. Research suggests that primary BMS may be linked to nerve dysfunction or problems with taste perception.

2. Secondary BMS

In these cases, the burning sensation can be traced back to another underlying condition, such as:

  • Dry mouth (xerostomia), often linked to medication use or health conditions
  • Nutritional deficiencies, such as low iron, folate, or vitamin B levels
  • Allergic reactions to certain foods, flavourings, or dental materials
  • Acid reflux causing irritation in the mouth and throat
  • Oral habits such as teeth grinding or tongue thrusting
  • Oral infections or inflammatory conditions
  • Side effects from medications
  • Emotional or psychological factors including anxiety and depression

Identifying whether BMS is primary or secondary is essential in shaping the treatment plan

Who is Most at Risk?

Although burning mouth syndrome is relatively rare, some groups are more likely to develop it. The risk is higher for:

  • Women over the age of 50
  • People experiencing hormonal changes, particularly during or after menopause
  • Patients with chronic health conditions such as fibromyalgia or autoimmune diseases
  • Individuals with high stress levels, depression, or anxiety
  • Those who have had recent dental treatments or use multiple medications

Lifestyle factors such as allergies, poor nutrition, or exposure to irritants may also contribute to the risk.

Complications to Be Aware Of

While BMS does not cause physical damage to the mouth, the constant discomfort can significantly affect quality of life. Patients often report:

  • Difficulty eating or enjoying meals
  • Interrupted sleep patterns due to pain
  • Emotional distress, anxiety, or depression

These secondary effects can be just as debilitating as the burning itself, which is why seeking professional care is important.

Diagnosis: What to Expect

When you visit Thousand Smiles for an evaluation, we take a step-by-step approach to uncover potential causes. This may include:

  • Reviewing your medical history and current medications
  • Examining the mouth and oral tissues for any irregularities
  • Asking about dietary habits, lifestyle, and stress levels
  • Performing diagnostic tests such as:
    • Blood tests to detect nutritional deficiencies or health conditions
    • Allergy testing to rule out sensitivities
    • Oral cultures to check for infections

The goal is to rule out other treatable conditions and determine whether your symptoms point to primary or secondary BMS.

Treatment Approaches

The best treatment depends on the type and suspected cause of the syndrome.

For Secondary BMS

When the burning sensation is linked to another condition, addressing that condition often reduces or eliminates the symptoms. For example:

  • Managing acid reflux with medication or lifestyle changes
  • Correcting nutritional deficiencies through supplements
  • Adjusting medications if side effects are contributing to dry mouth
  • Treating oral infections or dental issues

For Primary BMS

Since there is no single known cause, treatment usually focuses on symptom management. Possible options may include:

  • Special oral rinses designed to soothe tissues
  • Saliva substitutes to combat dryness
  • Medications such as antidepressants or nerve-related drugs in certain cases

At Thousand Smiles, we tailor treatment to each patient. Some individuals benefit from a combination of medical and self-care strategies.
