Root Canal Treatment
Root canal treatment is a highly effective procedure that saves natural teeth from extraction when they become damaged, infected, or severely decayed. This endodontic treatment involves carefully removing the infected pulp from inside the tooth and sealing it with special materials to restore its health and function. Our skilled endodontist in Long Beach at Marina Endodontics helps patients preserve their natural smiles while avoiding costly replacements like bridges or implants.
We follow a meticulous process to ensure the best outcomes for our patients requiring root canal therapy. Dr. Ahmed Sadek begins with a thorough examination to determine if this treatment is appropriate for saving your tooth. Our experienced team then removes the damaged tissue, cleans the interior thoroughly, and seals the tooth to protect it from future infection.
Root Canal Retreatment
Root canal retreatment becomes necessary when a previous root canal therapy has failed or complications have developed over time. This specialized procedure involves removing existing filling material and thoroughly cleaning any remaining infection or bacteria from the tooth’s interior. Dr. Ahmed Sadek and his team provide this advanced treatment as an effective alternative to tooth extraction.
Our comprehensive retreatment process at Marina Endodontics begins with a detailed examination to confirm the need for additional intervention. We carefully remove the previous materials, reshape and disinfect the canals, then fill them with new sealing materials to restore the tooth’s health. Our experienced endodontist in Long Beach ensures that the entire root canal system receives proper treatment to prevent future complications.
Cracked Teeth Treatment
Cracked teeth require prompt attention to prevent further damage and potential infection that could compromise your oral health. These fractures can occur from trauma, grinding, or biting hard objects, leaving the tooth vulnerable to bacteria and decay. Early intervention with appropriate cracked teeth treatment helps preserve the natural tooth structure and prevents the need for extraction.
Marina Endodontics offers comprehensive evaluation and treatment options tailored to the severity of your specific crack or fracture. Dr. Ahmed Sadek assesses each case individually to determine the most effective approach, which may include root canal therapy or other restorative procedures. Our skilled endodontist utilizes advanced techniques to repair damaged teeth and restore their function while maintaining your natural smile.
Tooth Resorption
Tooth resorption occurs when your body begins breaking down and absorbing the hard tissues of a tooth, including dentin and cementum. This condition can develop from trauma, inflammation, or orthodontic treatment, and requires immediate attention to prevent tooth loss. Without proper intervention, tooth resorption can lead to complete destruction of the tooth structure and compromise your oral health.
Dr. Ahmed Sadek specializes in diagnosing and treating this complex condition through advanced root preservation procedures. We perform comprehensive evaluations to determine the underlying cause and extent of the resorption before developing a customized treatment plan. Our experienced endodontist at Marina Endodontics utilizes specialized techniques to save affected teeth and prevent the need for extraction or replacement.
Endodontic Surgery
When non-surgical treatments like root canal therapy prove insufficient or impossible, endodontic surgery provides an advanced solution for complex dental issues. This specialized procedure addresses severe tooth damage, infection, or anatomical variations that standard treatments cannot resolve effectively. Various surgical techniques, including apicoectomy and resorption repair, help preserve natural teeth that might otherwise require extraction.
We utilize state-of-the-art surgical techniques to treat conditions affecting the tooth’s root and surrounding tissues with precision and care. Dr. Ahmed Sadek performs these complex procedures for patients referred by dentists throughout the Long Beach area who require specialized intervention. Our skilled endodontist at Marina Endodontics ensures that even the most challenging cases receive appropriate treatment to maintain your natural smile.
GentleWave
GentleWave represents a revolutionary advancement in endodontic care, utilizing state-of-the-art ultra-cleaning technology to thoroughly disinfect root canal systems. This minimally invasive procedure uses sound waves and specialized disinfectants to remove bacteria, tissue, and disease more effectively than traditional methods. The advanced cleaning capability of this innovative treatment helps preserve more natural tooth structure while reducing the likelihood of future retreatments.
Marina Endodontics proudly offers this cutting-edge technology as a safe adjunct to conventional root canal therapy for enhanced treatment outcomes. Dr. Ahmed Sadek utilizes the GentleWave device to provide patients with superior cleaning of inner canals while maintaining tooth strength for years to come. Our experienced endodontist combines this advanced technology with proven techniques to deliver exceptional care for decayed, infected, or damaged teeth.

What is a root canal?
Dental pain isn’t always straightforward. Issues like deep decay, cracked teeth, or infection can cause discomfort that radiates beyond the problem tooth, sometimes into the jaw, head, neck, or even the ear. This is because the teeth and gums are connected to a complex network of nerves.
A root canal is a specialized treatment that removes the infected or inflamed tissue inside the tooth, relieves pain, and helps you keep your natural tooth. At Marina Endodontics, Dr. Sadek uses advanced techniques to pinpoint the exact source of your discomfort and provide treatment that’s both effective and gentle.

FAQs
What makes endodontic retreatment different from initial root canal treatments?
Endodontic retreatment involves completely removing previous filling materials and thoroughly re-cleaning the tooth’s interior using advanced techniques like our GentleWave system. This second-chance procedure addresses failed root canals that didn’t heal properly or developed new infections. Our endodontist’s microscopic approach allows us to visualize and treat areas that may have been missed during the initial treatment, often saving teeth that might otherwise require extraction.
How do you handle patients with dental anxiety during endodontic care?
Our professional manner and calming demeanor help anxious patients feel comfortable throughout their visit. We explain each step of the procedure and use advanced pain management techniques that often allow patients to relax completely during treatment. Many patients report feeling so comfortable they actually fall asleep during their root canal, which speaks to our commitment to creating a stress-free environment for endodontic services.
What advanced diagnostic tools do you use for complex cases?
We utilize Cone Beam Computed Tomography (CBCT) for three-dimensional imaging of teeth and surrounding structures, which is invaluable for diagnosing cracked teeth, tooth resorption, and complex root canal anatomy. Our digital X-ray systems provide high-quality images for precise diagnosis, while our 360-degree visualization capabilities allow complete assessment of internal tooth anatomy. All procedures are performed under Zeiss surgical microscopes for enhanced precision and better outcomes.
Can you treat tooth resorption and other complex endodontic conditions?
Yes, our endodontist specializes in managing challenging cases including both internal and external tooth resorption, where the body’s own cells break down dental hard tissues. We also treat cracked teeth ranging from hairline fractures to more complex splits and vertical fractures. Our advanced diagnostic techniques help identify problems that may not appear on standard X-rays, allowing us to provide specialized treatments that preserve your natural tooth structure.
What should I expect during recovery from endodontic surgery?
Recovery from procedures like apicoectomy (root tip surgery) typically involves minimal discomfort when performed with our advanced endodontic techniques. Most patients experience little to no swelling and can return to normal activities within a day or two. Dr. Sadek personally follows up with patients after surgery to monitor healing progress and address any concerns. Our endodontist’s minimally invasive approach promotes faster healing while preserving the blood vessels and surrounding tissues essential for proper recovery.
