Root Canal Therapy (Endodontics for an Infected Tooth) – Greenfield, MA

5 Services ( View All )


When caught early, tooth decay can be treated with a dental filling or a similar procedure to clean the enamel and seal the area. However, if the decay expands past the enamel and infects the inner pulp of the tooth, you will need a root canal. Also known as an endodontic treatment, root canal therapy at Western Mass Endodontics removes the infected pulp from the tooth, cleans the cavity, and then uses a filling material to seal the tooth. Our team of dentists recommends a root canal procedure for our northern MA patients because it not only treats the infected tooth, but it also prevents the decay from spreading to other teeth (and creating larger problems).

If you suspect you need to have a root canal, we understand if you have reservations about having this procedure. A root canal is a very common dental therapy, yet many people put off going to see a dentist for a toothache because of dental anxiety. Our team will do their very best to make sure you are at ease and relaxed, but we also offer several methods of sedation for any anxiety. Contact one of our offices to schedule a consultation and learn more about root canals and sedation dentistry.

Best Candidates

An infection in the pulp of a tooth can be caused by a deep crack or cavity in the tooth or a physical trauma. Some of the most common signs that you may have an infected tooth are tooth or jaw pain, swelling or discoloration of the gums around the tooth, and changes in the color of the tooth. If the infected pulp is not removed, it will become increasingly painful as the infection spreads to other parts of your mouth. Schedule an appointment at Western Mass Endodontics as soon as you feel or see something abnormal in your mouth. If you have anxieties and fears about visiting the dentist, please ask us about sedation options to keep you calm and comfortable during your exam and treatment.

What To Expect

Before the procedure, you will discuss your sedation and/or anesthetic options with your dentist. We want you to feel at ease and relaxed while you are at our office. Many patients request nitrous oxide sedation (laughing gas) or oral-conscious sedation to get them through a root canal. Our dentists are very understanding about dental anxieties and will help you make the appropriate decision on how to proceed.

During an endodontic procedure, we will assess the inner chamber of your tooth and then carefully remove the infected pulp. From there, the inside of the empty chamber will be thoroughly sterilized to remove leftover decay. Once it is cleaned, the tooth will be filled with a special material to seal and protect it.


Depending on the type of sedation that was used, you may need to have a responsible adult take you home after your procedure. Your mouth may feel sensitive or swollen, but this should not last more than a few days and can be treated with over-the-counter pain relievers. You should schedule a follow-up appointment for six months after your root canal. Your dentist will check to see that the infection is gone and that your mouth has healed. After that, you should continue to schedule annual dental exams and bi-annual cleanings to maintain your dental health.

Insurance Coverage

During your consultation, we will go over cost estimates so your treatment fits both your needs and budget. If you have dental insurance, we can contact your carrier to determine your coverage. If you don't have dental insurance, Western Mass Endodontics accepts many payment methods, and we can help you find low-interest medical financing.
