Root Canals

When tooth decay occurs, it can lead to the formation of cavities on the hard enamel of the teeth. These small holes can provide a gateway for bacteria to enter the dental pulp, including blood vessels and nerves. This can result in inflammation and infection of the tooth. A root canal may be needed to treat the affected tooth and prevent further damage.

Signs you may need a root canal

If you are experiencing tooth pain or sensitivity, this could be a sign that you have an infection and need a root canal. 

Common signs that you need a root canal include:

  • Discomfort while biting and chewing
  • Sensitivity to hot and cold foods
  • Constant pain
  • Swollen gums
  • Tooth discoloration

If you are experiencing any of these symptoms, seeking treatment as soon as possible is important. If left untreated, an infection in the teeth and gums can spread to the tooth root, which may lead to the tooth needing to be extracted.

The procedure

If detected early, a root canal is a simple and uncomplicated procedure that can help your dentist restore your tooth’s health. Firstly, your dentist will use a local anesthetic to numb the area and minimize discomfort. Next, a hole is drilled into the tooth’s centre so they can access the infected tooth pulp. Blood vessels and tissues are removed from the tooth, preventing the infection from spreading. After the tooth pulp has been removed, the chamber and roots of the tooth are cleaned and disinfected. A flexible, rubbery material is inserted into the empty pulp chamber and root canals and is then sealed with a temporary dental filling. The seal helps keep bacteria from getting into the tooth. Once the procedure is complete and healed, the next step is to get a dental crown over the treated tooth to ensure that your teeth are protected and to restore your bite.


Experiencing some pain after the procedure is common, as the area will be tender. Over-the-counter pain medication is recommended, as the pain should subside within a few days. During this time, avoid eating hard feet that may damage the filling. Our team at Guildford Family Dentistry is committed to providing personalized dental care that meets your dental needs and goals. If you have any questions or would like to schedule an appointment, do not hesitate to reach out and contact our team or book an appointment.
