I’ve Heard That Root Canals Are Scary! Why Do I Need One?


It’s possible for the pulp, or soft tissue, inside of your teeth to become infected or inflamed. This can happen as a result of decay, repeated dental procedures on the same tooth, trauma and cracks or chips, or even a faulty crown.


We’ve all heard at some point that root canals are big, scary dental procedures – but they aren’t bad at all! When a root canal is required, it’s often in an effort to save your tooth from further harm and pain!


The process involves our highly skilled in-house Endodontist carefully removing the infected pulp of a tooth, then a cleaning and reshaping of the inside of the tooth. It’s then filled with a specialized material that will disinfect and seal the root canal.

When undergoing a root canal with 425 Dental, you can rest assured that you’re in the best hands. The 425 Difference means:

  • Your root canal is performed by an in-house, expertly trained Endodontist
  • The procedure is performed quickly and efficiently with sedation options
  • Your general dentist is right nearby to answer any questions you or the specialist may have
  • We are in-network with almost all insurances
  • We offer an in-house membership plan to help with payments if you aren’t covered by insurance

How Can I Be Sure I Need A Root Canal?


A root canal can be an effective way of treating some immense dental pain, or preventing issues that your dentist thinks will be imminent without intervention.


425 Dental proudly offers you the opportunity to visit us for a second opinion consultation on a previous dental diagnosis! After all, you want to be sure you’re getting the proper care for your unique situation.


We’re happy to assess your situation and let you know our thoughts – so you can make a more informed decision for your needs!

Am I a Candidate for Sedation Dentistry?

425 Dental is dedicated to making sure you are always as comfortable as possible, and receiving your care in a safe environment.


We proudly offer sedation options in our offices so that any issues with pain or anxiety regarding your appointment are well managed. While under sedation, our in-house Endodontist is able to perform your root canal with extreme precision and without wasting any time! Our team is highly skilled in the administration of sedation, and will ALWAYS be right by your side to monitor you, adjust sedation levels as necessary, and make sure you’re safe.

  • Laughing Gas
    • Laughing gas is often used for smaller procedures that don’t require oral surgery, such as root canal treatment. This gas is administered through a small mask over the nose, and will relax the patient while they receive the care they need. When under the effects of laughing gas you may feel giggly and silly, hence the name, but very unaware of the treatment being given to you. The gas wears off very quickly after your treatment is complete – but it’s’ best to have someone else drive you home!
  • Conscious Sedation
    • 425 Dental may also suggest conscious sedation for your root canal procedure. This involves a bit of medication that’s taken orally or via a small injection. The anesthesia will take effect in 30-60 minutes, and place you in a very drowsy state that may even put you into a light sleep. You’ll be able to be woken up at any time and even respond verbally, but you may not remember much once the effects wear off. We will continually monitor you the entire time!

Most, but not all patients are good candidates for sedation dentistry. We will always review your unique situation and remain up-front and clear about any sedation options for your procedure that you may have.
