Update the common sense of toothpaste (2/3: Process of teething)

I send out life hack information such as healthcare and promote the metabolism of common sense! His main book is " Let's metabolize common sense of health! "

Do you have an image of an "irreversible process" that you can't cure yourself if you have cavities?In fact, tooth decay is a "reversible process" that you can heal yourself up to a certain state.

Continuing from the last time, this time we will introduce a mechanism called this reversible process as the second review of the common sense of toothpaste.

Knowing this process of caries changes the consciousness of the mouth after eating. You may have noticed that chewing gum and toothpaste, which you were trying to avoid making cavities, actually shortened the life of your teeth. We would appreciate it if you could update the common sense that your efforts will produce the right effect.

Common sense metabolism point

Old common sense

Tooth decay is irreversible (need to be treated)

New common sense

The initial stage of tooth decay is a reversible reaction (healed without treatment)

Recommended for such a person

  • Those who want to know the mechanism by which cavities can be made
  • Those who are making an effort to take care of their teeth

Process of tooth decay

Adhesion of plaque

After meals, bacteria that are always present in the mouth break down and metabolize sugars and lean acidically. In the acidic state, saliva bridges and connects teeth and plaque (*).

※Plaque = plaque

It is a mass of adhesive substance produced by bacteria and their bacteria, with a composition of 75% of them, and the rest of which are produced by bacteria. The adhesive material serves as a barrier and prevents the entry of saliva.

The mouth is too good to go out and mouthful that is effective immediately after meals.

If sugar in the mouth is removed early, acid is not produced, so it is difficult to become acidic. For this reason, the most effective thing after meals is "too much mouth, mouth".

Tooth demineralization and remineralization

Demineralization = tooth corrosion due to plaque

If the plaque is left as it is, bacteria in the plaque decompose sugar during meals and drain the acid. This acid increases, and when the pH on the surface of the tooth is 5.5 or less, the tooth melts. The phenomenon of melting this tooth is called demineralization . The pH in the mouth inclines acidicly for 40 minutes after meals, during which the teeth continue to melt. Toothbrushing in this condition is not recommended. This is because the teeth are easy to melt, so it is easy to shave when brushing your teeth.

Remineralization = repair of teeth using saliva minerals

In the neutral region where the pH is 6.0 or higher, tooth demineralization stops. During this pH, the teeth are repaired by phosphoric acid and calcium in saliva. This phenomenon is called remineralization.

Progression of tooth decay = demineralization > remineralization

In daily life, the above-mentioned demineralization and remineralization are repeated. Cavities progress in the case of demineralization > remineralization.

Uncle
I had an image of an irreversible event with tooth decay
Child
It's good to increase the amount of remineral lime!
Uncle
So, each time you eat, you'll break away from ashes each time you eat, so it's better not to eat too much
Child
er, that's it!
Uncle
If you really want to snack, you can choose one that doesn't contain sugar Nuts
Child
I understand eating nuts!

Tooth decay progression

The degree of progression of cavities is categorized from C0 to C4 depending on the tooth part.

Cavity Stage

If the green progression in this figure is the degree of progression, it can be cured by remineralization. I tried to organize the state and pain of the degree of progress in the table below. Please refer to it.

stageCorrosion reaching locationsStatepainTreatment methods
RemineralizationTreatment at the dentist
C0Tooth surfaceThe surface of the tooth is demineralized on the surface of the vitiligo and cloudiness enamel, and it looks white.WithoutAvailable
C1enamelthe state in which enamel reaches the inner surface ofWithoutAvailable
C2dentina cavity that has reached dentin beyond enamelSince it has not reached the pulp, there is no strong pain It bites with cold things and sweet things When progressing, hot things also bitepassable?The corrosion part is shaved off, and the buried thing is made.
C3nerveCavities that have reached the pulp There are no subjective symptoms, and cavities may have progressed to the pulp. The infection of bibacteria advances fast, the nerve is killed, and it comes to have the bag of pus ahead of the root when left. (Percussive periodontitis)In addition to the above, it may cause pulpitis and severe pain.NotNeed for nerve-taking treatment (root canal treatment)
C4The tip of the root of the nerve (crown)The decaying of the teeth due to tooth decay, leaving the roots Most of them are infected with bibacteria at the tip of the roots. (percuss periodontitis) If left alone, it will progress more and more and the need for tooth extraction will increase.dittoNotNerve-taking treatment (infection root canal treatment) or tooth extraction

Determination of cavities

It is said that tooth decay cannot be judged by appearance. Even if it is black, it may not be cavities. If you are worried, let's go to the dentist.

Caltar production

If plaque is left untreated, the saliva component phosphoric acid and calcium will settle and become firmer and firmer. And it is said that if left as it is, it will take 2 to 14 days to become tartar. If it becomes tartar, it will not be possible to remove it unless you go to the dentist.

Uncle
Is the bozu chewing gum?
Child
Yes, gum with xylitol prevents tooth decay. It's effective because it gets a lot of saliva, right?
Uncle
Yes, saliva is effective, but if you have plaque, you may make tartar
Child
Well, say it now! What happens when tartar is made?
Uncle
As soon as the tartar is made, blood comes out of the gums, it smells and it is the worst, especially the back of the lower front teeth is in front of the saliva line, so be careful because it is easy to make tartar
Child
Ok , gum will be chewed after removing plaque properly

Summary

How did you like to introduce the process of tooth decay?

Cavity process summary memo

  • For 40 minutes after meals, the sugar in the mouth is decomposed and tilted to acidity, demineralization and teeth soluble.
  • When the mouth returns to neutrality, remineralization repairs the teeth.
  • Cavities are a reversible process of demineralization and remineralization, but progresses when demineralization > remineralization.
  • If plaque remains, the teeth will be made without repairing the teeth by remineralization.
  • When tartar is made, it becomes easy to get blood out of the gums, the smell is tight and it is the worst, and it can not be removed unless it is a dentist.

In the next section, I will introduce the best tooth care method in me after knowing the process of tooth decay in the next section!
