Overview: why bad breath happens and what to do first
Bad breath (halitosis) is usually caused by plaque and gum disease, a coated tongue, dry mouth, or untreated decay and infection. In Canberra, heated indoor air during winter and seasonal allergies can worsen dry mouth and post‑nasal drip, both of which increase odour‑producing bacteria.
The first step is a dental assessment to confirm the cause and rule out gum disease or infection. Most people improve with a professional clean, targeted home care and treating any decay or gum inflammation.
Common signs bad breath needs attention
- Bad taste or odour that persists beyond 2–3 weeks
- Bleeding, tender or swollen gums; build‑up between teeth
- Dry mouth, thick saliva or a visible coating on the tongue
- Sensitivity, food catching or pain suggesting decay
- Denture odour or a bad smell from a crown, bridge or implant
Urgent care is needed if there is facial swelling, fever or severe pain. Otherwise, prompt routine care helps prevent progression to gum disease.
Treatment options in Canberra
Your dentist will tailor care to the cause. Typical steps include:
- Comprehensive exam and x‑rays (if indicated)
- Professional scale and clean; periodontal therapy if needed
- Treating decay, leaking fillings or food traps
- Tongue cleaning and interdental cleaning coaching
- Dry mouth strategies: saliva substitutes, fluoride, and medication review with your GP if appropriate
- Referral to a periodontist (gum specialist) for advanced cases
Same‑day and after‑hours appointments are often available around Civic, Belconnen, Woden, Tuggeranong and Gungahlin.
What you can do at home right now
- Clean your tongue gently from back to front with a tongue cleaner
- Floss or use interdental brushes daily; brush twice daily with fluoride toothpaste
- Sip water often; choose sugar‑free xylitol gum or mints
- Use alcohol‑free mouthwash as advised by your dentist
- Reduce tobacco, alcohol and strong‑smelling foods before important events
Home care helps, but a dental exam is key to rule out gum disease or decay.
