Why Do I Need a Root Canal If I’m Not in Pain?

Woman wondering why she needs a root canal

While you were at your dental checkup, did your dentist tell you that you need a root canal relatively soon? If you aren’t in any pain, it might seem odd that they recommended this treatment. However, it’s important you get this procedure right away, as it can have serious complications if not. Here’s why you need a root canal, despite not being in any pain, so you feel confident getting it for your oral health.

Why Do I Need a Root Canal Despite Not Being in Pain?

You need this treatment when you have an infection inside your tooth. This can happen due to decay, cracks, or a chip, but these can introduce bacteria to the inner dental pulp. Over time, this can cause a severe toothache, but you may not be in any discomfort at first.

There are two main situations in which you may not be in any pain, such as:

  • Your dentist found the problem early, before it could cause any complications.
  • You had a toothache, but it went away over time as the nerve had been damaged.

Either way, both of these are serious emergencies. The longer you wait to get treatment, the more you risk the infection spreading to nearby teeth and gums.

What Are Other Signs I Need a Root Canal?

Although persistent dental pain is a common symptom, there are other signs that indicate you need a root canal. You may have sensitivity to hot or cold foods and overly sweet options as well. This feels like a sharp and sudden feeling you’ll experience that lingers after eating them.

When you need a root canal for a cavity, you may also notice a dark spot on a tooth. If it’s an infection, then you may also have swollen gums. If there is a pimple-like bump in the soft tissues near the affected tooth, then you should call your dentist right away.

In the end, persistent discomfort isn’t always a sign that you need a root canal. While you may be curious about why you need this procedure, you can always talk to your dentist. They have a better understanding of your smile and will let you know more about why they made this recommendation. That way, you feel confident getting it for your smile and get toward a stronger grin you love.
