Tartar doesn t smell in the mouth, so why does it stink when it comes off the teeth?

Our mouth mainly feels taste, while our nasal cavity mainly feels smell, and can sense whether it is fragrant or smelly. The mouth is connected to the esophagus, and the nasal cavity is connected to the trachea. Although the nasal cavity and mouth are also connected, it is difficult to smell the inside of the mouth.

Because he went along with it, and then it was all fermenting inside, so he couldn't smell it.

Because the tartar picked out from the teeth lingers on the teeth for a period of time, the teeth have undergone certain changes during the period of stay, resulting in a peculiar smell.

These foods remain between the teeth, fermentation, decay after its stink, but usually do not smell the smell, this is left between the teeth, the smell can not come out, and a saliva has a sterilization and anti-inflammatory effect, so usually can not smell the smell, if once thrown out with a toothpick will be very smelly.

The items picked out on the teeth, most of them are residual ingredients, and the mouth is not cleaned immediately after eating, and the residual food is mellow and stinky inside, so it is all stinky to pick out, especially in the case of eating fish, this kind of food remains in the gap between the teeth, and it smells extremely bad after being mellow and rotten, but it usually does not smell the peculiar smell, this is the reason why the residue is in the teeth and the peculiar smell does not come out, and then a saliva has the effect of sterilization and swelling, so it usually does not smell the peculiar smell, if it is cast out with a wooden skewer, it will be very smelly.

This is because when the teeth chew food, there will be some food residue left between the teeth, no matter how to rinse the mouth, there will be some, plus the mouth spit, the composition is complicated, the mouth is closed for a long time, the tooth-impregnated items gradually thicken and harden, the original is to remove its dross, after a long time, pick out, smell of course strange smell. That is, the sediment of the ingredients, if not treated in time, this sediment will be deposited under the effect of germs and minerals in the saliva to produce dental calculus, and under the long-term erosion, it will gradually become alcoholic, dissolve an enzyme, produce carbon dioxide gas, and exhale it together with the internal vapor of the mouth.

The nose breathes in and the mouth rests! The mouth is breathing air, the nose is resting! The relationship between the two is good, don't fight!

The structure of the human nasopharynx depends on the fact that the nose only smells the smell of the nasal cavity, and the stains and dental stones picked off the teeth are located in the mouth, close to the nasopharynx, which is also the "back" of the nose, so it can't smell! In fact, such a thing should be a stain (food residue), which is also a major manifestation of dental calculus in the early stage. Before the dental calculus has become a dental calculus.

It is also only soft and yellowish plaque bacteria and food residues and tooth stains, which adhere tightly to the teeth of its own mouth, although it cannot be washed away or rinsed by water, but with the help of physical methods, such as brushing and rinsing and flossing sticks, it can still be cleaned. Our nose and the inside of the mouth are different from the external environment, that is to say, the sense of smell and taste are different, and some food residues in the mouth are under the effect of microbial strains, which will cause some tasteful organic compounds, but the taste bud effector in the mouth cannot be experienced.

Most of this tartar is formed by the accumulation of food, and there will be a lot of bacteria that will have a very smelly taste, and there is no taste sense organ in your mouth, so you can't feel the taste.

Because the tartar attached to the teeth is a medium for bacteria to multiply and multiply, the bacteria ferment with the starch and carbohydrates in the tartar, which will emit a sour odor; Because our mouth is only responsible for the experience of taste, and the sense of smell can only be smelled by name, the mouth cannot smell tartar.

The soft palate part behind the human mouth is connected to the nasal cavity, and it is impossible for the nasal cavity to smell the problems caused in the oral cavity, and the olfactory cells are present in the upper part of the nasal cavity. In addition, the olfactory senses need to adapt to the environment. When my nose lingers on a particular smell for a long time, I slowly get used to it, which is the result of central nervous system control.

This is a problem of the anatomy of the human body, because our mouth is only responsible for the experience of taste, and the sense of smell can only be smelled through the nose.

This is also the reason why many people obviously have severe bad breath but are unconscious, because they can't smell the odor in their mouths at all, and only after the people next to them smell it, they can realize it according to the feedback or reaction of others. Therefore, if the other party has a cold and nasal congestion, they will not be able to smell the foul smell of the speaker's mouth.

Ways to avoid tartar formation.

1. Avoid residual between teeth.

A large part of the formation of plaque is due to the fact that the food residue left between the teeth is fermented and decomposed for a long time, which is prone to odor. Therefore, you can brush your teeth in time after eating, and even if you don't brush your teeth, you should maintain the habit of rinsing your mouth, so that you can take away most of the food residues.

2. Scaling your teeth. Some tartar is easy to form tartar in the later stage, and tartar needs to be removed by scaling in time, which can also effectively help us freshen our breath.
