Endodontics - Treatment of Tooth Root Canals

VivaDens offers endodontic diagnostics and treatment, using dental microscope („Carl Zeiss“ „OPMI pico“). Endodontic treatment helps to preserve natural teeth and is applicable for treatment of root canals of tooth. Because of endodontic treatment it is possible to preserve decayed or very infected teeth. Endodontic treatment is necessary when soft tissue (pulp) inside a root canal of tooth is inflammatory or infected.

Iliustration from "Change your Smile", Ronald E.Goldstein, DDS

"Endo" is Greek language word meaning "inside" and "odont" – “tooth”. In the inside of tooth (under enamel and dentin layer of tooth) there is soft part of tooth that is called pulp. It is composed of blood vessels, nerves, connecting tissue. Pulp continues from tooth crown to a root end which is connected to tissues around a root. If pulp of tooth is damaged, blood vessels and nerves broke down and tooth becomes lifeless.

Inflammation or infection in root canal may arise due to different reasons: deep caries, tooth fractures, cracks, etc. If originated inflammation or infection is not treated, then a tooth becomes painful and abscess may develop. If canals are not treated, bacteria get into surrounding tissues through a root apex and cause inflammation. Eventually jawbone is being lost around an infected tooth and inflammation spot forms.

When endodontic treatment is necessary?

Endodontic treatment is necessary when a pulp (soft tissue of tooth root) becomes inflamed or infected. Inflammation or infection may have many reasons: deep caries, numerous teeth procedures or teeth crack, fracture or other trauma. Besides, teeth trauma may also cause pulp damage even when tooth factures or cracks are not visible. If pulp inflammation is not treated, it may cause pain or abscess formation.

The main signs that endodontic treatment is necessary are pain, long lasting sensitivity to heat or cold, sensitivity to touching and chewing, pain without a cause, change of teeth color, swelling of gingiva. However, there may be cases when no symptoms are present. Dentist during consultation will determine whether Your teeth need to be treated endodontically.

Endodontic treatment procedure

Endodontic treatment may be performed during one or several visits. First of all doc. dentist makes and evaluates dental radiograph. After tooth is anesthetized it is isolated by dental dam in order the work area would be clean and to prevent getting of saliva, infection into this area, and also prevent therapeutic materials getting into mouth.

Afterwards the dentist through a top of tooth crown opens tooth pulp. By using very small instruments, the dentist carefully removes infected or inflamed pulp, widens tooth canal, forms it and sterilizes.

After cleaning and forming a canal, doc. dentist isolates root canals completely by filling them with biologically compatible material which is called gutta-percha. In some cases this root canal treatment may be finished in one visit. In such case root canal is filled and teeth crown is restored by restorative filling.

If tooth canal is infected, during the first visit therapeutic calcium paste is left within a root canal of tooth. During the second visit, tooth canal is sealed and chamber in tooth crown part is filled with permanent filling.

After endodontic treatment, teeth crown is restored by restorative material or crown and functions as a natural tooth.

Whether all teeth may be treated endodontically?

Generally all teeth may be treated endodontically. Very rarely a tooth may not be longer preserved, because root canals of tooth are obstructed. However, the modern achievements of science of endodontics enable also to preserve such teeth which earlier could only be extracted.

Care of endodontically treated teeth

Before the dentist has not restored completely teeth crown, it is not recommended to chew or bite with endodontically treated teeth. An incompletely restored tooth is sensitive to fractures, thus immediately after cleaning of tooth root canals and their filling, it is necessary to restore a tooth crown completely. After doc. dentist restores tooth crown, take care of endodontically treated teeth the same way as of other teeth.

In many cases endodontically treated tooth serves as long as the natural one. Cases happen when endodontically treated tooth does not cure and pain does not stop. Very rarely happens that one month or a year after successful endodontic treatment a tooth becomes painful. In such cases a tooth may be preserved by re-treating it endodontically.

How much endodontic treatment costs at VivaDens?


Endodontic treatment samples of complicated root canals (performed at VivaDens):

First molar teeth No.16 in upper jaw after the canal treatment procedure. All canals are filled up to their physiological root apexes. Canals of proximal buccal root are very curved, filled with Gutta-Core system allowing qualitatively to obturate the curved canals. Other canals are filled with thermoplastic guttapercha using vertical condensation method with Calamus Dual system.
