A leading dental expert has issued an urgent warning about a common mouth symptom that could indicate a serious underlying health condition affecting thousands of Britons.
The Hidden Danger in Your Mouth
Dr Surina Sehgal, a respected dental surgeon, reveals that persistent mouth ulcers and oral sores that refuse to heal might be more than just a nuisance - they could signal a dangerous vitamin B12 deficiency. This essential vitamin plays a crucial role in nerve function and red blood cell production, and its absence can have severe consequences.
Recognising the Warning Signs
While occasional mouth ulcers are common and usually harmless, Dr Sehgal emphasises that certain characteristics should raise red flags:
- Ulcers that persist for more than three weeks
- Multiple sores appearing simultaneously
- Pain that interferes with eating and drinking
- Recurrent outbreaks without obvious cause
- Sores accompanied by tongue inflammation or burning sensations
Why Vitamin B12 Matters
Vitamin B12 deficiency affects approximately 6% of adults under 60 in the UK, with the figure rising dramatically to 20% in those over 60. The vitamin is essential for maintaining healthy nerve cells and producing DNA, and its deficiency can lead to neurological problems if left untreated.
"Many people dismiss mouth ulcers as stress-related or accidental bites," explains Dr Sehgal. "But when they become a recurring problem, it's crucial to consider nutritional deficiencies, particularly B12, which can cause various oral manifestations."
Who's Most at Risk?
Certain groups are particularly vulnerable to developing B12 deficiency:
- Vegetarians and vegans (B12 is primarily found in animal products)
- Older adults with reduced stomach acid production
- People with digestive disorders like Crohn's disease
- Those taking certain medications long-term
- Individuals who've had weight loss surgery
Beyond Mouth Sores: Other Symptoms to Watch
Dr Sehgal notes that mouth ulcers often appear alongside other concerning symptoms:
- Extreme fatigue and lack of energy
- Pins and needles sensation (paraesthesia)
- Muscle weakness
- Psychological disturbances including depression
- Memory problems and confusion
"The mouth is often the first place nutritional deficiencies show themselves," Dr Sehgal adds. "Dentists are frequently the first healthcare professionals to spot these warning signs during routine check-ups."
When to Seek Medical Advice
Healthcare professionals recommend consulting your GP if you experience persistent mouth ulcers alongside other symptoms of B12 deficiency. A simple blood test can confirm the diagnosis, and treatment typically involves B12 supplements or injections.
Early detection is crucial, as prolonged deficiency can lead to irreversible nerve damage and neurological complications. Don't ignore what your mouth might be trying to tell you about your overall health.
