Causes of halitosis

Many things can be responsible for causing bad breath in you. Since there are many types of bacteria in the mouth, there is no wonder why your mouth may smell bad from time to time. Below are a few things that cause halitosis. 

  • Poor oral health – anyone who does not brush/floss regularly is creating a comfy breeding ground for bacteria in their mouth. Since food particles get stuck in the mouth, this moist environment causes bacteria to multiply rapidly. Once the food starts rotting in between your teeth and gums, you will experience halitosis/bad breath. 
  • Periodontal disease – Periodontal, AKA gum disease, is the process of decaying gum lines due to poor oral health for a long period of time. This causes you to have bad breath as well as an unpleasant taste in your mouth. 
  • Dry mouth – Dry mouth indicates little to no saliva present in your mouth. Since saliva helps clean up your mouth naturally, the absence of it cause you to have food particles linger around in your mouth. This also causes you to have halitosis in your mouth. 
  • Certain foods – it’s a lie if you say that the onion you had for lunch didn’t leave any smell in your mouth. It’s no secret that certain foods cause you to have bad breath till it leaves your system. Onions are just one of them!
  • Tobacco – There’s no doubt that all things tobacco causes some kind of issue in your body. Halitosis is just one of the issues tobacco causes. These products will also cause issues in your mouth, such as gum disease, oral cancer, irritated gums, and so on.

  • Diabetes – diabetes is also linked to causing halitosis. If you suspect you have bad breath due to undiagnosed diabetes, consult a doctor as soon as possible.
