Signs you may need a root canal treatment
Lingering Pain
Serious pain when you eat or put pressure on an area can be a sign of infection. Additionally, if the area still hurts after the pressure has subsided (or even without pressure) you should see your dentist.
Hot or Cold Sensitivity
If its extremely uncomfortable or even painful when you eat hot or cold foods, it can be a sign that decay has begun to expose the underlying nerves. This is especially true if the pain or sensitivity lingers even after your done eating.
Swelling in the Gums
Gums that are swollen or have small bumps around the area where you are experiencing pain can indicate that you’ll need to see your dentist to discuss whether you need root canal treatment.
Darkening of the Tooth
A change in colour, especially darkening, is a sign that the tooths nerve has died.
