Bleeding gums: when should I see a dentist?
Bleeding when brushing is a reason to check your gum health.

Bleeding when brushing or cleaning between teeth needs attention. Red, swollen or painful gums can indicate gum disease. Only an examination can establish the cause and suitable care.
Plaque irritates the gums. Careful daily cleaning of teeth and the spaces between them is important for prevention. Your dentist can demonstrate a suitable technique and assess the need for professional cleaning or other treatment.
Book an examination for bleeding, painful or swollen gums, or persistent bad breath. Seek an urgent dental appointment for severely painful, swollen gums or a tooth becoming loose.
You do not need to know which procedure you need in advance. Leave the category blank when booking and describe your symptoms to reception. After examination, your dentist will suggest a plan for your condition.
