What Is ANUG (Acute Necrotising Ulcerative Gingivitis)?
If your gums are suddenly bleeding, painful, and swollen especially with a bad taste or smell you may be experiencing Acute Necrotising Ulcerative Gingivitis (ANUG), a severe gum infection that needs urgent attention. Unlike common gum irritation or gingivitis, ANUG progresses rapidly and can lead to permanent damage if left untreated.

What causes ANUG?
The condition is triggered by a build-up of bacteria in the mouth, often made worse by:
• Poor oral hygiene
• Poor immune health
• Illness
• Stress
• Smoking
• Alcohol
• Vitamin deficiencies
This causes the gum tissue to break down, resulting in painful ulcers and persistent bleeding, painful gums.

Symptoms to Watch Out For
It’s important to monitor your symptoms. Contact a dentist urgently if you notice bleeding, painful gums with:
• Ulcers on the gums
• Bad taste or smell in the mouth
• Swollen lymph nodes
• Raised temperature
• Feeling tired or generally unwell
These may indicate a dental infection, which requires prompt antibiotic treatment.

Do I Need Antibiotics for ANUG?
Most cases of ANUG do require antibiotics. Treatment also includes improved oral hygiene and professional cleaning, where possible.
