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.

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.

Options that may be considered

Dental and gum assessment

Assessment can identify plaque, gum disease, decay, infection or food trapping.

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.

Choosing the next step

Use the emergency pathway only when the problem may need urgent review.

For routine, planned, or unclear but non-urgent concerns, book a normal appointment. For swelling, trauma, severe pain, bleeding, or a broken tooth that cannot wait, use the emergency assessment instead.

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.
