Endodontics
Endodontics is a specialized field of dentistry focused on the structures inside the teeth, including the pulp, tissues, nerves, and blood vessels. The term "Endodontics" comes from the Greek words meaning "inside the tooth." Endodontists undergo additional training after dental school to perform both simple and complex procedures, such as root canal therapy, to save damaged or infected teeth.
Signs and Symptoms of Endodontic Problems
-
Inflammation and tenderness in the gums
-
Sensitivity to hot and cold foods
-
Pain when chewing or biting
-
Tooth discoloration
-
Unexplained pain in nearby lymph nodes
Reasons for Endodontic Treatment
-
Endodontic treatment, often known as root canal therapy, is designed to save a tooth with internal damage or infection. Despite advanced dental restorations, natural teeth remain the best option for long-term oral health.
-
Common causes of damage to the inner tooth include:
-
Bacterial Infections: Oral bacteria can invade the tooth pulp through cracks caused by decay or injury, leading to inflammation, infection, and abscess formation.
-
Fractures and Chips: A large portion of the tooth crown can become detached, exposing the pulp and causing pain and infection.
-
Injuries: Trauma to the mouth can dislodge a tooth or damage the pulp, often requiring root canal therapy after the tooth is stabilized.
-
Tooth Loss: If a tooth is knocked out, it should be rinsed and placed back into its socket or stored in a special solution or milk until dental care can be provided. After stabilization, root canal therapy may be necessary to save the tooth.
-
What Does an Endodontic Procedure Involve?
-
Root canal therapy usually takes one to three visits to complete and involves the following steps:
-
Initial Examination and X-rays: X-rays are taken to assess the condition of the tooth.
-
Local Anesthesia: A local anesthetic is applied to numb the area.
-
Dental Dam Placement: A protective sheet is placed to keep the surgical area free from saliva.
-
Tooth Opening and Pulp Removal: The dentist creates an opening in the tooth to access and remove the damaged pulp using small instruments.
-
Shaping, Cleaning, and Filling: The empty space is shaped, cleaned, and filled with gutta-percha, a biocompatible material similar to rubber. A temporary filling is placed to restore function.
-
Permanent Restoration: In a follow-up visit, a permanent filling or crown is applied to seal and restore the tooth.
If you have any concerns about endodontic treatment or root canal procedures, it’s always best to consult with your dentist for more information.
Cracked Tooth
Cracked and fractured teeth are common dental issues, especially as people retain their natural teeth longer. The risk of cracks increases due to behaviors like biting hard objects, trauma, and teeth grinding. These activities place additional strain on teeth, making them more vulnerable to cracks.
Symptoms of a Cracked Tooth
-
Unexplained pain while eating
-
Sensitivity to hot and cold foods
-
Pain with no clear cause
-
Difficulty pinpointing the location of the pain
The pain often occurs when pressure is applied, as the crack widens and exposes the tooth's pulp, causing irritation. The pain may subside once pressure is released, but if left untreated, the pulp can become damaged and infected, affecting surrounding bone and soft tissue.
Types of Cracks
-
The type of crack determines the appropriate treatment. Some cracks can be treated with root canal therapy to save the tooth, while others may require extraction. Common types of cracks include:
-
Crazes: Tiny vertical cracks in the enamel, usually harmless and considered a normal part of tooth anatomy. These cracks rarely require treatment but may be treated cosmetically if they affect appearance.
-
Oblique Supragingival Cracks: Affect only the crown of the tooth and typically do not extend below the gum line. The affected portion may break off but causes minimal pain.
-
Oblique Subgingival Cracks: These cracks extend beyond the gum line and often cause pain. They may require periodontal surgery and endodontic treatment to restore the tooth with a crown or other device.
-
Vertical Furcation Cracks: Occur when the roots separate. This type of crack typically affects the tooth's nerve. Root canal therapy and a crown can often save the tooth.
-
Oblique Root Cracks: These cracks affect the root below the gum line, often causing significant damage. Root canal therapy may be an option, but extraction is often required.
-
Vertical Apical Root Cracks: These cracks occur at the tip of the root and cause severe pain. Root canal therapy may provide temporary relief, but extraction is often the final solution.
-
Treatment for Cracked Teeth
-
Treatment depends on the type and severity of the crack:
-
Minor Cracks: If the crack is small and only affects the tooth surface, cosmetic treatments may be used.
-
Root Canal Therapy: For cracks that affect the tooth pulp, the pulp is removed, and the space is filled with gutta-percha. A crown or filling is then placed to stabilize the tooth.
-
Extraction: If the crack is too severe, the tooth may need to be extracted. Restorative options like bridges, dental implants, or partial dentures can replace the tooth and restore function.
-
If you have concerns about a cracked tooth, it’s important to consult your dentist for proper diagnosis and treatment options.
