What is Root Canal Treatment (Endodontic Therapy)?

Root canal treatment (endodontic therapy) is a dental procedure to remove infected, inflamed, or necrotic pulp tissue from the tooth's pulp chamber and root canals, followed by cleaning, shaping, disinfection, and obturation of the canal system.

Modern endodontics uses nickel-titanium rotary or reciprocating instruments, electronic apex locators, irrigation with sodium hypochlorite and EDTA, and three-dimensional obturation with gutta-percha and bioceramic sealers under rubber dam isolation and dental operating microscope.

Indications include irreversible pulpitis (severe spontaneous pain), pulp necrosis with apical periodontitis, dental trauma with pulp involvement, deep caries approaching the pulp, and elective endodontics for prosthetic restoration. Success rate exceeds 95% with proper technique and case selection.

Symptoms

Severe spontaneous toothache, especially at night
Prolonged sensitivity to hot or cold lasting minutes
Pain on biting or chewing (apical periodontitis)
Tooth discoloration (pulp necrosis)
Swelling or abscess in surrounding gum or face
Sinus tract draining pus on gum
Deep caries or fracture exposing pulp

Risk Factors

Untreated deep dental caries
Dental trauma (fracture, luxation, avulsion)
Repeated dental procedures on same tooth
Cracked tooth syndrome
Periodontal disease with pulp involvement
Bruxism causing tooth wear and pulp exposure
Failed previous endodontic treatment requiring retreatment

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Severe persistent toothache
  • Sensitivity to hot/cold lasting more than 30 seconds
  • Pain on biting or pressure
  • Visible swelling or pus drainage
  • Tooth discoloration after trauma
  • Recurrent dental pain after filling or crown
  • Suspected pulp involvement on dental imaging

03
Pulp removal and canal exploration with hand and rotary files
04
Working length determination with electronic apex locator and radiographs
05
Canal cleaning and shaping with rotary nickel-titanium instruments
06
Irrigation with sodium hypochlorite, EDTA, and chlorhexidine
07
Three-dimensional obturation with gutta-percha and bioceramic sealer

Impacted Tooth

Ağız ve Diş Sağlığı

An impacted tooth — most often a wisdom tooth — has not erupted fully and remains in the jaw bone or gum. It can lead to pericoronitis, caries and cysts.

Dental Implants

Ağız ve Diş Sağlığı

A dental implant is a titanium screw placed in the jawbone that supports a crown, bridge or denture, providing the closest possible function and aesthetics to a natural tooth.

Teeth Whitening

Ağız ve Diş Sağlığı

Teeth whitening lightens tooth color using hydrogen peroxide or carbamide peroxide gels. In-office (professional) bleaching uses higher concentrations with light activation for faster results; home bleaching uses custom trays with lower concentrations over 1–4 weeks. Safety depends on healthy teeth, correct concentration, isolation of gums and transient sensitivity management.

Orthodontics

Orthodontics is the dental specialty that corrects the alignment of the teeth and jaws, providing both aesthetic and functional benefits at any age, from childhood through adulthood.

Gingival Recession (Gum Recession)

Ağız ve Diş Sağlığı

Gingival recession is the apical displacement of the gingival margin with exposure of the root surface. It may be localized or generalized and results from mechanical trauma, periodontal disease, thin biotype or anatomic factors. Recession can cause root sensitivity, caries and aesthetic concerns; management includes cause elimination and surgical root coverage when indicated.
