Tooth pain or discomfort can leave you wondering whether it’s something simple — like a small cavity — or something more serious, like an infection. So how do you know if you need a filling or a root canal? Let’s break it down.
Our Canadian dental team is here to help you make informed decisions, and this guide offers an overview of what to look for.
🦷 When Is a Filling Enough?
Dental fillings are used to treat minor to moderate cavities caused by tooth decay. Your dentist will remove the decayed portion and fill it with a strong material like composite resin.
Signs you may just need a filling:
- Small cavity or dark spot on your tooth
- Mild sensitivity to sweets or temperature
- No lingering pain
- No visible swelling
A filling is a quick, one-visit solution that restores your tooth’s function and appearance.
When a Root Canal Might Be Needed
If decay reaches the inner nerve (pulp) of the tooth, it can cause infection or inflammation. That’s when a root canal becomes necessary to save the tooth.
Signs you might need a root canal:
- Persistent, throbbing tooth pain
- Sensitivity that lingers long after eating or drinking
- Swelling around the gums
- A bump (abscess) on your gums
- Tooth discolouration or darkening
Your dentist will remove the infected pulp, clean the canal, and seal the tooth. Often, a crown is placed afterward for extra protection.
💼 What Should You Do?
The only way to know for sure is to book an exam. X-rays and a professional assessment are key to determining the best treatment.
Pro tip: Don’t ignore tooth pain! Catching issues early can mean the difference between a simple filling and a more involved procedure.
