1.1 Poor Oral Hygiene 

We cannot have fresh breath if we do not rinse our mouth and brush our teeth every morning. During the long hours of the night, bacteria can easily multiply and produce a foul smell. Therefore, brushing your teeth every morning is an important task to eliminate odor-causing bacteria, stimulate the taste buds, and enhance the taste of food.

Saliva can smell bad when leftover food particles are not cleaned and remain stuck in the teeth. Bacteria decompose this food, causing it to mix with the saliva being secreted. When you talk, an unpleasant smell can be detected by the person you are speaking to. Therefore, we should use dental floss to thoroughly clean leftover food after eating.

1.2 Consuming Foods with a Strong Smell 

When drinking green tea, eating fresh ginger, or consuming raw vegetables, your breath smells fresh. However, foods like shrimp paste can give your mouth a distinctive smell. When you talk, it’s easy to identify what you’ve just eaten. However, this phenomenon is not too worrisome as it does not harm the body’s health. After eating, you just need to brush your teeth thoroughly, and your breath will be fresh again.

1.3 Wearing Dentures or Removable Dental Appliances 

Dentures and removable dental appliances serve to improve chewing. However, if not used properly, leftover food can stick to them and cause bad-smelling saliva. Therefore, it’s necessary to clean dentures and removable dental appliances thoroughly using specialized cleaning solutions. If you find that the size of the denture or appliance does not fit you, it should be adjusted to avoid damaging the mucous membrane and gums.

1.4 Aging 

As we age, the process of aging spares no one. This affects the health of our teeth and mouth to some extent. Our immune system weakens, making it less effective in combating harmful agents from the outside. Therefore, the aging of the salivary glands also becomes less efficient, slowing down the production and secretion of saliva.

At this point, the mouth often becomes dry, giving bacteria the opportunity to proliferate and cause foul-smelling saliva in the oral cavity. Moreover, this phenomenon also occurs similarly in people who drink little water or frequently use medicinal products.

1.5 Oral Diseases 

All oral diseases have the potential to make the saliva and breath of the patient smell bad to varying degrees. Commonly, deep black cavities, severe gum inflammation, pulpitis, dental abscesses, or excessive dental plaque are all culprits causing bad smell in the oral cavity and saliva. Especially, gum inflammation with bleeding and pus discharge is even worse.

As a result, the saliva has a rancid smell of pus and blood being secreted. The sense of taste is also affected by these substances. Patients will feel a slight bitterness at the tip of the tongue and lose their appetite when eating daily. Inflamed gums when wisdom teeth erupt create a pocket for food to stick to. It’s very difficult to clean all the leftover food in this pocket. Therefore, bacteria decompose the protein in the food, creating a smell for the saliva. Typically, inflamed gums usually appear from 18 to 28 years old, corresponding to the period when the 8th tooth erupts after other permanent teeth.

1.6 Digestive Diseases 

The digestive system also affects the health of the teeth and mouth to some extent, which is an obvious fact that few people pay attention to. Accordingly, individuals with respiratory diseases or gastroesophageal reflux disease will have bad breath from saliva along with it. The cause is due to food, gastric juice, and stomach acid escaping out through the mouth, making the saliva smell bad.

Individuals with sinusitis, sinusitis, bronchitis, tonsillitis, pharyngitis, chronic lung infection, lung cancer also make the breath and saliva have an unpleasant smell. No matter how well you clean your teeth and mouth, you cannot avoid this bad smell.
