How do I recognise early periodontitis?

Early periodontitis often begins with gums that bleed when brushing. Persistent bad breath that does not go away after cleaning is a warning sign. The gums may be red and swollen rather than pink and firm. Sometimes there is a metallic taste caused by blood from inflamed periodontal pockets. Teeth may become slightly more sensitive as recession begins. Periodontal pockets of 4-5 mm can be measured during a professional examination. X-rays may show early bone loss between the teeth. Early detection prevents irreversible damage to the supporting tissues. Professional dental cleaning and improved oral hygiene can halt the progression. Six-monthly check-ups are essential for patients at risk.
