Why do I have bad breath?
Bad breath can be uncomfortable to talk about, but it is a common concern. Dental causes often relate to plaque, gum inflammation, tongue coating, food trapping, dry mouth, decay or infection.
What you may be worried about
- Bad breath may mean gum disease or infection.
- It may affect confidence socially or at work.
- Mouthwash may mask the issue without solving it.
Common patterns people notice
- bad breath
- bad taste
- dry mouth
Possible causes
- Plaque and bacteria around teeth or gums.
- Gum inflammation or periodontal pockets.
- Tongue coating, dry mouth or food trapping.
- Decay, failing dental work or infection.
When to treat this as urgent
Urgency level: routine
- Bad breath comes with swelling, pain, pus or fever.
- There is a bad taste from one area.
- Teeth feel loose or gums bleed frequently.
What to do now
- Notice whether bad breath is constant, linked with one area, dry mouth, bleeding gums or a bad taste.
- Keep cleaning teeth, gums and tongue gently while arranging assessment if it persists.
- Seek urgent help if bad breath is linked with swelling, pus, fever or severe pain.
What to avoid
- Do not rely on mouthwash alone if bad breath keeps returning.
- Do not ignore bad taste from one area, gum bleeding or loose teeth.
When to arrange a dental assessment
- Arrange assessment if bad breath is persistent, new, linked with bleeding gums, food trapping, bad taste or discomfort.
What a dentist may need to assess
- Gum health, plaque and tartar, tongue coating, dry mouth, decay, food trapping, infection and failing dental work.
Options that may be considered
Cleaning and home care changes
Professional cleaning and targeted home care may reduce bacterial causes.
Medical review
If dental causes are unlikely, medical or sinus-related factors may need consideration.
What we would consider before recommending treatment
- Gum health and plaque levels.
- Dry mouth, medications, diet and medical factors.
- Decay, infection or failing restorations.
If it were our own teeth
If it were our own concern, we would want a non-judgemental assessment to identify whether the cause is dental, gum-related or something else.
A sensible next step
Book an appointment if bad breath is persistent, new, or associated with bleeding gums, bad taste or discomfort.
Possible next steps
- Professional cleaning, gum treatment, home care changes, decay repair, infection management or medical review may be discussed.
Common questions
Is bad breath usually dental?
It often has dental or gum-related contributors, but dry mouth, sinus and medical factors can also play a role.
Will mouthwash fix bad breath?
Mouthwash may temporarily reduce odour, but persistent bad breath needs the cause identified.
