Do Cavities Cause Bad Breath?
Everyone has experienced bad breath at some point. It’s an unpleasant moment when you catch a whiff of your own breath and wish you’d packed some gum. For most of us, regular brushing and flossing help keep it under control. But what if you’re sticking to your oral hygiene routine, getting dental cleanings, and still noticing persistent bad breath?
Unaddressed cavities may harbour bacteria that can cause chronic bad breath. Your dentist can check for cavities or other potential underlying causes of bad breath to help you achieve your oral health goals.
What Are Cavities?
Cavities are small holes that develop in your teeth due to tooth decay. Tooth decay occurs when the protective enamel on your teeth starts to break down, often due to bacteria feeding on sugars and producing acid.
While cavities are common in children, they can affect people of any age. Over 96% of adults have had at least one cavity in their lifetime.
Adults are most prone to two types of cavities:
Recurrent Cavities
These form around existing fillings or dental work. Because fillings disrupt the smooth surface of a tooth, they can create small pockets where bacteria and food particles collect, leading to decay over time.
Root Cavities
Root cavities occur when the gums recede—whether from age, gum disease, or brushing too hard. Receding gums expose the tooth’s root. Since roots don’t have the same enamel protection as the rest of the tooth, they’re more susceptible to decay.
If left untreated, cavities can create an environment for bacteria to thrive, and the decay can reach the inner pulp of the tooth. This can lead to pain, sensitivity, infections, or worse, requiring procedures like root canals or tooth extractions.
Do Cavities Cause Bad Breath?
Cavities don’t cause bad breath on their own, but they create the perfect environment for bacteria to thrive. These bacteria produce sulphur compounds that smell foul—like rotten eggs.
If a cavity is left untreated, the bacteria within it can continue to release these odours, contributing to chronic bad breath.
Think of a cavity as a sneaky trap where bits of food can hide and decompose, adding even more to the stink. However, cavities are not the only possible culprit for bad breath.
What Else Causes Bad Breath?
Bad breath, also called halitosis, can stem from a variety of other factors, even for those without cavities.
Here are some of the most common underlying causes:
- Bacteria on the tongue: Your tongue’s surface can harbour bacteria, especially towards the back where it’s harder to clean.
- Dry mouth: Saliva helps wash away particles and bacteria. Dry mouth, caused by dehydration, certain medications, or mouth breathing, can allow bacteria to flourish.
- Pungent foods and drinks: Garlic, onions, coffee, and alcohol are notorious offenders when it comes to bad breath.
- Gum disease: Gum infections create pockets in your gums where bacteria can accumulate, causing unpleasant odours.
- Smoking or tobacco use: Besides leaving a lingering odour, tobacco use can dry out your mouth and increase your risk of gum disease.
- Medical conditions: Issues like sinus infections, postnasal drip, or gastrointestinal conditions can also affect your breath.
How to Address Bad Breath & Cavities
Chewing on ice cubes or hard candy may seem harmless, but they can cause significant damage to your teeth. These items can crack or chip your teeth, leading to potentially serious dental issues.
Avoiding the habit of chewing on hard substances and opting for softer alternatives can help protect your teeth from unnecessary damage.
Chewy & Sticky Foods
Stay Hydrated
Practice Good Oral Hygiene
Brush your teeth twice a day and floss daily to target areas your toothbrush can’t reach. Don’t forget to clean your tongue, too, as bacteria can stick to your tongue. Many toothbrushes now come with a tongue scraper on the back for this purpose.
Opt for Sugarless Gum
Limit Sugary and Acidic Foods
Visit Your Dentist Regularly
Scheduling regular dental check-ups lets your dentist catch issues like cavities or gum disease early before they worsen. Regular cleanings also prevent plaque and tartar buildup to preserve your oral health and lower your risk of developing cavities.

What If I Suspect Cavities Are Behind My Bad Breath?
How Cavities Are Treated
- For small cavities, your dentist will remove the decayed portion and fill it with composite resin, porcelain, or another material.
- For more advanced decay that has infected the tooth’s pulp, root canal therapy may be necessary.
- If a tooth is beyond repair, the dentist might recommend extraction and replacement with a crown, implant, or bridge.
The good news? Treating a cavity not only stops its progression but also tackles the bacteria contributing to bad breath.
