What Causes Plaque Smell

You’re likely noticing an unpleasant smell from plaque due to the bacteria that forms on the teeth and gums, and consequently, can lead to gum disease and other dental problems. Plaque smell is caused by:

  • Bacteria:
  • Bacteria builds up in the mouth, and when it mixes with saliva, it produces the plaque smell.
  • The bacteria also causes inflammation, which can further irritate the gums and cause bad breath.
  • Poor dental hygiene:
  • If you don’t brush and floss your teeth regularly, plaque can accumulate and worsen the smell.
  • The longer plaque stays on the teeth, the worse the smell becomes.

Plaque smell can be uncomfortable and embarrassing, but it doesn’t have to be. With proper oral hygiene and regular dental visits, you can keep your mouth healthy and prevent plaque smell from occurring.

Everyone deserves to feel confident in their smile, so be sure to take care of your oral health.

What Are the Different Types of Plaque Smells

Different types of plaque smells can range from mild to strong and unpleasant. It could be caused by poor oral hygiene, tooth decay, gum disease, or bacteria.

It’s important to keep good oral hygiene to help prevent plaque buildup. Brushing twice a day, flossing, and regular dental checkups with your dentist can all help reduce plaque and its associated smells.

Mild plaque smells may be similar to the smell of food that has been stuck in the mouth for some time. Stronger smells may be more like an unpleasant, sour, or metallic odor.

It’s important to address any persistent bad breath, as it could be a sign of a more serious dental issue. Taking care of your oral health can help ensure that your plaque smells are kept to a minimum.


Plaque can have a variety of smells, ranging from a mild, musty odor to a more pungent, sour smell.

For example, one case study found that a patient’s plaque had a strong, sulfur-like smell which was attributed to the presence of bacteria in the mouth.

Ultimately, it’s important to maintain good oral hygiene to prevent plaque and its associated odors. Regular brushing and flossing, along with regular dental visits, are essential for a healthy mouth and a fresh breath.
