A student suffers from tooth decay and feels pain, indicating that the tooth has been damaged

I said that there is an error in the answer to your multiple-choice question, there is caries, it means that the enamel of your teeth has been damaged, and caries is divided into shallow caries, medium caries, deep caries, middle caries is the destruction of dentin, deep caries is to indicate that the dentin has been destroyed a little deep, and the pulp cavity is very close, but the absence of pulp piercing indicates that the pulp has not been damaged, and the cementum is at the root of the tooth, which is not so easy to be damaged. Tooth pain indicates that the pulp must have been damaged, because damage to dentin, cementum, and enamel will not cause pain.

This question seems to be less rigorous, because when the tooth decay reaches the dentin layer, the tooth will have hot and cold soreness, and when it reaches the pulp, there will be spontaneous pain (that is, pain without eating) and night pain. I only say that I feel pain, so I think soreness shouldn't be considered pain, so I choose B.

b。It is damaged to the pulp nerve, so it will cause pain.

Landlords can try Aole V fluoride-free children's toothpaste. I have a good baby, the main ingredient in the product novamin reacts quickly and continuously with water and saliva, releasing ions to promote the growth of tooth tissue: it produces a stable crystalline hydroxyphosphate limestone layer mineralization on the enamel surface, supplementing tooth structure minerals and repairing tooth enamel function safely and quickly.

The effect of this toothpaste is really good, but it is more expensive, but if it has an effect, it is worth it. The landlord can search for their official ** on the Internet to see, it seems that ** is also sold.

It's not too late to tell your classmates to make amends.

Most toothaches are tooth decay, and pulpitis may also be possible.

Go to the dentist for a root canal**.

A root canal** can be done, or some medications can be taken by mouth temporarily.

The so-called root canal is the cavity in the middle of the tooth root, the so-called root canal ** is to make a hole in the surface through dental instruments, take out or kill the residual nerve in the root canal, and then place an anti-inflammatory cotton wool twist in the root canal to eliminate the tooth inflammation, and the tooth will not hurt if there is no inflammation. It can also be sealed and wrapped (porcelain sleeve, cast crown sleeve).

The drug can choose the classic analgesic roxithromycin tablets + periodontal kang + aminophen codeine tablets (can relieve temporary pain, can not **).

I'm a dentist and hope mine can help you!

If in doubt, you can go ahead and ask me.
