Caries

?What is caries

Caries is tooth decay ,commonly called cavities .              

 There are several factors for caries:                          

*Dental defects

*High-acid or low-fluoride environment

*Reduced salivary flow

Tooth decay is caused by bacteria which are in dental plaque.

Bacteria which present in the mouth normally do not hurt teeth ,this bacteria feed on dentine of teeth. This is the decay process.

As for the symptoms, tender, painful teeth – appear late.

Diagnosis is based on inspection, probing of the enamel surface with a fine metal instrument ,and dental x-rays.


 

?How do acids affect teeth         

We all know from  practical life that the acid dissolves limestone ,therefore, acids dissolve atoms of calcium. They eat into them when sugar and saliva and bacteria are mixed , so the acidity can dissolve the mineral content of the enamel ,making the teeth weaker , more sensitive , and more susceptible to decay .


 

?Now .. What is a tooth made of       

Tooth is an organic template contains a high proportion of calcium atoms , phosphorus , and other mineral salts .

To answer this question we need  to enumerate the parts of tooth which consists of enamel , dentin ,cementum and pulp , out of which , enamel is the hardest part that covers the dentin layer.

On the other hand , cementum is the bony structure that covers the root of a tooth ,while pulp is the central of connective tissues.


 

?Are all caries painful          

Carious in the lament is not painful , but it will cause pain if it moves the dentine (ivory) especially during drinking hot and cold , so the intensity of pain differs from person to person .

For example , there are sensitive people who feel a lot of pain .

Others may have the same necrosis but they do not  suffer from it until it moves to pulp .Here is the most dangerous stage where the bacteria reach the pulp. As a result ,the patient will not be able neither to bear the pain nor to sleep. Also painkillers will not help him in mitigation the pain  . In this case he must see a dentist for pulpectomy


 

?What is the treatment

At first , if caries was within the tooth enamel or dentine, the dentist cleans the tooth from tissues  containing dissolved calcium , after that he fill the tooth up either by silver dental filling or by composite . Caries also may be in the pulp , in this case , it need pulpectomy ,cleaning the channel pulp and expanding it to be ready for filling .Finally , dental restoration according to the effected tooth


 

?How is the dental  restoration of tooth which is severely effected

Of course there are several ways , but dentist is the one who determines The appropriate way according  to his experience.

These ways begin from putting the filling inside caries hole if there are walls surrounding the teeth , or putting a screw within the channel which is cleaned, emptying , filled and inhabited by  the pulp. Then begin put the screw in the outer part of the channel, and filler up with filling to be more durability.

But if the tooth is severly affected , we have to take an impression and send it to the  dental laboratory for preparation of a metal mold which made of molded filling that placed within wall of the tooth .

Then we make a crown for the tooth to maintain it , because each tooth especially the back of them  which we removed its pulp earlier is weak, fragile and breakable as a tree branch. For that , crowning is the best way to maintain it .
