What Causes Bad Breath?

What Causes Bad Breath?

Hi, it’s Suzie from Sure Dental.  I think I can safely say that no one wants halitosis. That’s bad breath. I am often asked about it. What causes bad breath? And how can it be prevented? It’s more common than you might think, affecting 1 in 4 adults, globally. So I thought I’d make this short video.   

The most common cause of bad breath is poor oral hygiene and dental bacteria. Dry mouth, smoking and gut health are also common causes. 

Dental bacteria is a sulphur producing bacteria that colonise in the mouth, on your teeth, under your gums and even on your tongue. The amounts of bacteria can increase with gum disease, infection and dental decay, and unfortunately, it smells. The good news is, here at Sure Dental, we can treat and prevent this!

A professional dental clean here at Sure Dental is an excellent way to prevent bad breath. Not only cleaning your teeth and removing plaque and calculus, our Oral Health Therapist will give tips and will go over your home care routine and will get to the root cause. With some simple habits, we can prevent bad breath. Things like flossing your teeth daily, this can remove and disturb bacteria from between your teeth where the toothbrush cannot reach. Here is a fun fact, did you know that brushing with your toothbrush only reaches around 65% of the tooth surface?  

Cleaning your tongue daily with a tongue cleaner or toothbrush can help to prevent bad breath and of course, brushing your teeth twice per day, when you wake up and before you go to sleep. Ensuring good, gentle brushing technique and brushing for a minimum of two minutes.

Also, it’s important to stay hydrated. When you have a dry mouth, there isn’t any saliva to neutralise acids that are produced by dental bacteria and plaque and this can cause bad breath. Alcohol, stress, medications and some medical conditions can cause dry mouth, so be aware and drink lots of water. 

The next thing is smoking. Smoking starves the mouth of oxygen which leads to all sorts of health issues, including bad breath. If you’re a smoker, you know what to do. 

Finally, gut health can also impact your breath. If you have a gut imbalance, certain types of bacteria can flourish in your gastrointestinal tract and can cause bad breath.  

So to prevent bad breath, make sure you have excellent oral hygiene habits at home and be sure to have regular professional cleans and Preventive Care appointments.
