Bad Breath Treatment in North York
Bad breath that keeps coming back can be embarrassing. In most cases the cause is in the mouth, and your dental team can help you find and treat it.
Bad breath treatment in North York at Emerald Forest Dental focuses on finding the source. Most lasting bad breath, called halitosis, comes from bacteria on the tongue, between teeth or in gum pockets. Your dentist checks for gum disease, cavities, dry mouth and old dental work, then suggests treatment and home care that targets the cause.

About bad breath treatment
The smell in most bad breath comes from sulphur compounds made by bacteria. These bacteria live in places with little oxygen, such as the coating on the back of the tongue, deep gum pockets, food trapped between teeth and gaps around old fillings or crowns. Brushing the teeth alone often misses these spots, which is why mints and mouthwash only help for a short time.
Several dental problems can feed these bacteria. Gum disease creates pockets that trap debris. Cavities and broken fillings hold food. Dentures, retainers and night guards can build up film if they are not cleaned well. Dry mouth is another big cause, since saliva normally washes bacteria away. Many medicines, mouth breathing, smoking and not drinking enough water can all reduce saliva.
Your visit starts with questions about when the smell is worst, your health, your medicines and your cleaning routine. Your dentist then checks your teeth, gums, tongue and any appliances. Treatment often includes a cleaning, fixing leaky fillings or cavities, treating gum disease and learning to clean your tongue. If no dental cause is found, your dentist may suggest you see your doctor, since sinus problems, tonsil stones, acid reflux and some medical conditions can also affect breath.

Other options
Mouthwashes, mints and gum can mask bad breath for a short time, and some rinses can lower bacteria for a while. They work well only together with treating the cause, not on their own. Alcohol-based rinses can dry out the mouth, so ask us which type suits you.
Cost and coverage
Since bad breath has many possible causes, the cost depends on what your dentist finds. For some people it is a single exam and cleaning; for others it may include fillings or gum treatment. Fees are usually based on the ODA suggested fee guide, and most insurance plans cover exams and cleanings. We always explain the plan and expected costs first. If you are a Canadian Dental Care Plan member, ask our team whether it can be used at our clinic. LendCare payment plans can help with larger treatment.
Our promise: we confirm your coverage and explain the cost before treatment.

Bad Breath Treatment FAQ
What is the most common cause of bad breath?
Bacteria on the back of the tongue and between the teeth are the most common sources. Gum disease and dry mouth are also frequent causes. Food like garlic and onion causes short-term odour that fades on its own.
Will mouthwash cure my bad breath?
Mouthwash can freshen your breath for a few hours, but it does not fix the cause. If the smell keeps coming back, a dental visit can help find out why.
How do I know if I have bad breath?
It is hard to smell your own breath. You can lick the inside of your wrist, let it dry and smell it, or ask someone you trust. A bad taste that keeps returning is another clue.
Can my medicines cause bad breath?
Many medicines, including some for blood pressure, allergies and mood, reduce saliva and cause dry mouth. Do not stop them on your own. Your dentist can suggest ways to manage dry mouth.
What if my dentist does not find a cause?
If your teeth and gums are healthy, the cause may be in your nose, sinuses, tonsils or stomach. Your dentist will suggest you speak with your family doctor.
