What happens to an infected tooth if left untreated?

If your endodontist or dentist has indicated a need for root canal treatment, it means that a tooth is infected. The tooth remains infected until a root canal treatment is completed or the tooth is extracted. If it is not treated promptly, the infection can spread and form an abscess. An abscess is an accumulation of pus (thick, yellowish fluid) that is formed naturally by the body to contain an infection and to prevent it from spreading. It appears as a pink/red swollen area and they are generally painful due to the pressure of the pus building up.

What are the possible causes of sudden increased tooth sensitivity?

Tooth sensitivity is a brief sensation of sharp pain experienced when the dentinal layer of a tooth is exposed to stimuli; typically thermal in nature. Dentin is the yellowish layer found beneath the outermost white and hard enamel. When the protective enamel layer is lost or when the gum recedes, stimuli such as hot, cold, sticky or acidic food come into contact with the inner layers of the tooth and a signal is sent to the nerves inside the tooth. This, in turn, sends a signal to the brain and pain is felt.

Why is there a price difference for root canal treatment for molar and premolar teeth?

Let’s draw an analogy between teeth and houses. As everyone knows, when you want to renovate a big house, like a bungalow, you will require a lot more effort and material as compared to an apartment. As a result, one can guess that it would also cost more to renovate the bungalow. With that said, it is also more time consuming and labour intensive to treat a more complex tooth. For example, molar as it can have twice, thrice, 4 times or even 5 times as many root canals as a premolar or front tooth. Hence, the fees will also be higher.
