Bleeding gums: symptoms worth discussing with a dentist
Bleeding when you brush or clean between teeth should not be ignored. Gum disease is one possible explanation, and a dentist can assess your gums and advise on care.
What you may notice
Gum disease can cause red, swollen, sore gums that bleed during brushing or eating. Bad breath, a bad taste and receding gums may also occur. These observations are useful to report, but they cannot establish a diagnosis on their own.
When to book an appointment
See a dentist for bleeding, painful or swollen gums, or persistent bad breath. Seek an urgent appointment for very sore and swollen gums, loose teeth, mouth ulcers or red patches, or a lump in the mouth or on a lip. A child with sore or bleeding gums also needs dental advice.
Prepare a clear description
Write down whether the bleeding is occasional or frequent, whether one area or several areas are affected, and when you first noticed it. Tell the clinician about changes in medicines or your health. Ask them to show you an appropriate cleaning technique rather than guessing what to change.
Turn advice into a routine
At the appointment, ask for a short written plan: what to use, how to use it and when to return. If several products are suggested, ask which are essential and which are optional. This makes it easier to follow the advice and compare any proposed treatment costs without buying unnecessary products.
Questions to take to your appointment
- What is causing the bleeding in my case?
- Can you demonstrate cleaning between my teeth?
- What follow-up will show whether the plan is working?
Write down the answers in your own words and ask the practice to clarify anything unclear.
