What Is Root Canal Treatment?

Lakewood Ranch Dentist


Dr. Allison O’Brien provides root canal therapy for patients in the Lakewood Ranch area as a safe and effective way to save teeth that are severely damaged or infected. This treatment involves carefully removing the inflamed or infected pulp from inside the tooth, which contains nerves, blood vessels, and connective tissue. After the pulp is removed, the canals are meticulously cleaned, disinfected, and shaped to ensure all infection is eliminated and the tooth is fully prepared for restoration. Local anesthesia is administered throughout the procedure to ensure patient comfort, making the experience pain-free and manageable.

Once the canals are treated, a temporary filling protects the tooth while a permanent restoration, such as a crown, is placed to restore its strength, function, and appearance. Root canal therapy not only alleviates pain caused by infection or trauma but also prevents further damage to surrounding teeth and gum tissue. By preserving the natural tooth, patients maintain proper dental alignment and chewing function, supporting long-term oral health. Dr. O’Brien customizes each root canal treatment to the patient’s specific needs, ensuring precise, effective care that restores comfort and functionality while helping patients retain their natural smile for years to come.

Dr. Allison O’Brien and her staff are INCREDIBLE!!!! I have never received such amazing dental care in my life. Dr. O’Brien loves what she does and always puts me at ease. She is so patient and generous with her time. My cousin in Philadelphia is a dentist and I asked him if he could research a dentist in my area that REALLY is a TMJ specialist. He found Dr. O’Brien because he researched dentists that continually do extra training at a special institution in Tampa. Dr. O’Brien is that that Dentist!!! I will always be so grateful to her and her staff❤️❤️❤️❤️
