Root canals may sound a little daunting to some patients, especially when they are unaware of the full procedure. This is no worry with Dr. Lavi's work, however. Dr. Lavi's main goal is your comfort. A root canal is needed when a tooth gets infected and needs to be removed. Dr. Lavi constantly communicates with his patients throughout the procedure for their reassurance and makes sure that they are numb during the process. This procedure usually takes about 40 minutes per tooth, so we will be done before you know it.
