Bad Breath & Tooth Sensitivity

What Causes Bad Breath (Halitosis)?
Persistent bad breath is rarely just about what you ate for lunch. It’s usually a sign of something happening inside your mouth, and sometimes elsewhere in your body.
Plaque and tartar buildup
Bacteria feed on food particles and release odour-causing gases
Gum disease (gingivitis/periodontitis)
Infected gum pockets trap bacteria that standard brushing can’t reach
Dry mouth (xerostomia)
Reduced saliva means less natural rinsing of odour-causing bacteria
Tongue coating
Bacteria collect on the back of the tongue, a commonly missed spot
Tooth decay
Decayed tissue harbours bacteria and produces a distinct smell
Tobacco or alcohol use
Dries the mouth and leaves residue that feeds bacteria
Sinus or respiratory infections
Post-nasal drip introduces bacteria into the mouth and throat
Certain medications
Many common medicines reduce saliva flow as a side effect
If bad breath doesn’t go away with brushing, flossing, and mouthwash, the cause is usually below the surface and that’s when a dental check-up matters.
What Causes Tooth Sensitivity?
Sensitivity is that sharp, short jolt you feel when you bite into something cold, hot, sweet, or sour. It happens when the protective layer of your tooth wears down and exposes the dentin the softer layer underneath, which connects directly to your tooth’s nerve.
Cold drinks or ice cream
Likely cause: Worn enamel or exposed dentin
Hot tea or coffee
Likely cause: Cracked tooth or deep decay
Sweet or sour foods
Likely cause: Enamel erosion from acidic food or drinks
Brushing or flossing
Likely cause: Gum recession exposing the tooth root
Cold air
Likely cause: Exposed root surface near the gumline
Biting down
Likely cause: Possible cracked tooth or loose filling
Sensitivity is a signal, not just a nuisance. It’s your tooth telling you the protective layer isn’t doing its job anymore.
How Bad Breath and Sensitivity Are Connected
Both problems often trace back to the same source: gum disease. When gums pull away from the teeth (recession), two things happen at once the exposed root surface becomes sensitive, and the newly created pockets around the gumline become a hiding spot for odour-causing bacteria. Treating the gum problem often improves both symptoms together, which is why we look at your whole mouth, not just the symptom you called about.
How We Diagnose the Cause
Guessing doesn’t fix chronic bad breath or sensitivity a proper diagnosis does. At your visit, we typically:
Review your medical and dental history, including medications
Examine your teeth, gums, and tongue for plaque, decay, or recession
Check for signs of gum disease, including pocket depth around teeth
Identify sensitivity triggers with a simple in-chair test
Take X-rays if we suspect decay, a cracked tooth, or bone loss isn’t visible to the eye
Treatment Options
Plaque/tartar-related bad breath
Typical treatment: Professional scaling and polishing
Gum disease
Typical treatment: Deep cleaning (scaling and root planing), ongoing gum care
Dry mouth
Typical treatment: Saliva-stimulating advice, hydration guidance, medication review
Tongue-related odour
Typical treatment: Tongue cleaning technique and tools
Mild sensitivity
Typical treatment: Desensitizing toothpaste, fluoride varnish
Sensitivity from gum recession
Typical treatment: Bonding agents or gum grafting, depending on severity
Sensitivity from a cracked tooth or deep decay
Typical treatment: Filling, crown, or root canal treatment, as needed
We’ll always explain which option applies to you and why, before any treatment begins. Depending on the cause, this may include gum treatment, root canal treatment for a nerve-involved tooth, or crowns to protect a worn or cracked tooth.
Home Care That Actually Helps
While a dental visit finds the root cause, these habits support your treatment and help prevent recurrence:
Brush twice daily with a soft-bristled brush and fluoride toothpaste
Clean your tongue gently, especially the back
Floss once a day to remove plaque between teeth
Use a desensitizing toothpaste if you notice mild sensitivity
Stay hydrated to keep saliva flow steady
Limit acidic foods and drinks that wear down enamel
Avoid tobacco, which contributes to both dry mouth and gum disease
Don’t skip your six-month dental check-up, even if symptoms feel minor
When to See a Dentist Right Away
Book a visit sooner rather than later if you notice:
Bad breath that persists despite good oral hygiene
Bleeding, swollen, or receding gums
Sensitivity that’s getting worse or lasts more than a few seconds
Pain when biting down
A visible crack, chip, or dark spot on a tooth
These can point to a problem that needs treatment before it progresses.

Frequently Asked
Questions
Quick answers to the questions patients ask us most about bad breath and sensitive teeth. Have another question? Browse our full dental FAQs.
Can bad breath be a sign of a serious health problem?
Sometimes. Persistent bad breath can point to gum disease, a sinus issue, or another medical condition (we also offer early oral cancer screening). If it doesn’t improve with good oral hygiene, it’s worth a dental check-up to rule out an underlying cause.
Is tooth sensitivity always caused by decay?
No. Sensitivity can come from worn enamel, gum recession, a cracked tooth, or recent dental work, in addition to decay. A dental exam is the only reliable way to know which one applies to you.
Will mouthwash fix bad breath permanently?
Mouthwash can mask odour temporarily, but it won’t fix the underlying cause, such as gum disease or dry mouth. Long-term relief comes from treating the cause, not just covering the symptom.
Can sensitive teeth get better without treatment?
Mild, occasional sensitivity sometimes eases with a desensitizing toothpaste. But if it’s persistent or worsening, it usually needs a dentist to identify and treat the underlying cause.
How long does treatment for gum-related bad breath and sensitivity take?
It depends on the severity. Mild cases may improve after one professional cleaning and better home care. More advanced gum disease may need a series of deep-cleaning visits over a few weeks.
Ready for fresh breath
and comfortable teeth?
Bad breath and sensitive teeth both have real, identifiable causes and both respond well to the right treatment. If either one has been bothering you, it’s worth finding out why rather than living with it.
