Why Do Symptoms Sometimes Return After a Root Canal?

Dentist Blog

Many people have a few things about their body that they'd like to change. Sometimes you can change these things yourself (diet and exercise), and sometimes you might need some help (cosmetic procedures). But there are certain things about your body that you're powerless to change, such as the layout of your dental pulp chambers. But how is this even relevant to your life?

Your Pulp Chambers

You might be blissfully unaware of the fact that you even have dental pulp chambers. These chambers are found in each of your teeth, and they house your dental pulp, which is a nerve. Your bliss can rapidly come to an end when your dental pulp becomes infected, which means that a root canal is required. But surely the layout of a pulp chamber is largely the same, no matter whose teeth they are?

Root Canals

A root canal is among the most routine dental services. The tooth is opened, the infected dental pulp is removed, the chamber is disinfected and irrigated, and then it is packed with a filling material. Once the tooth is closed again (either with a standard filling or a dental crown), then your root canal is complete. So why might some people begin to experience a recurrence of the signs associated with an infected dental pulp?

Chamber Complications

It's not something that happens particularly often, but sometimes the layout of a patient's dental pulp chambers can complicate a root canal. Some teeth (particularly molars) have additional chambers, often extending downwards to the tooth's mesial root. It's not a given that pulp chambers are entirely vertical, and they can in fact vary slightly in their layout. The infected dental pulp can also result in a slight calcification of the chamber, making its exact layout unclear. This means that in some cases, a remnant of infected dental pulp has been left behind, which is why your symptoms have returned.

Correcting the Issue

A problematic root canal is more of an inconvenience than anything else. If untreated, your symptoms will persist and can even worsen, so it's simply a matter of performing an additional root canal. It's regrettable but preferable to leaving the tooth as-is. In order to understand the complexity of your specific case, your dentist will reopen the tooth and examine it under a dental microscope. 

Once every section of the pulp chamber has been mapped, the root canal will be performed again, and this should be the end of the matter. Contact dental services in your area to learn more.

Fillings: Everything You Need to Know

Hi! Welcome to my blog! My name is Kerry, and this blog is focused on dental fillings. It looks at the history of fillings, options for contemporary fillings, how to protect your fillings, when to replace them and much more. If you have ever had a cavity filled or if you are planning to get a tooth filled, you will find the information in this blog useful. I try to look at fillings from all angles, and I even plan to look at how to avoid fillings through proper dental hygiene and sealants. Thanks for reading, and I hope you find the info intellectually "filling."
