Signs You Need a Root Canal and What Happens If You Ignore Them

Signs You Need a Root Canal and What Happens If You Ignore Them

Tooth problems rarely announce themselves all at once. Dr Ian Blewitt, our specialist endodontist, explains that the symptoms relating to nerve and pulp damage tend to follow a recognisable progression, and catching them early makes a significant difference to both treatment and outcome.

The Early Signs

The earliest indication is often sensitivity to cold or sweet foods, and occasionally heat. At this stage, the issue can frequently be treated very minimally sometimes with a filling carried out by your own dentist or an endodontist - a quick, straightforward, and highly successful intervention.

It's worth noting that some sensitivity to cold is entirely normal: a brief, sharp sensation that passes quickly isn't necessarily cause for concern. What matters is anything that extends beyond a few seconds, or sensitivity to heat, or pain severe enough that you're considering painkillers.

What Happens If Symptoms Are Ignored

Left untreated, the nerve inside the tooth essentially "puts up a fight," in Dr Blewitt's words. This typically progresses to classic toothache symptoms - a gnawing, dull, persistent ache that doesn't reliably respond to over-the-counter painkillers. If it progresses further, it can develop into an abscess, with swelling, pain, and sometimes visible pus around the tooth.

Why Earlier Treatment Gets Better Results

At every stage of this progression, the treatment required becomes more extensive, and the long-term success rate of that treatment decreases. This is true whether the delay is due to simply not noticing symptoms, or to deliberately putting off treatment out of worry - both lead to the same outcome of a more complex, less predictable problem to resolve.

When to Book an Appointment

• Sensitivity to cold or sweet that lingers beyond a few seconds

• Any noticeable sensitivity to heat

• A persistent, dull, gnawing ache that doesn't respond to painkillers

• Spontaneous pain with no obvious trigger

• Swelling, tenderness, or pus around a specific tooth

Frequently Asked Questions

• Is sensitivity to cold always a sign I need a root canal?

  Not necessarily - brief, sharp sensitivity that passes within a few seconds can be normal. Sensitivity that lingers, or that's accompanied by heat sensitivity or spontaneous pain, is more concerning and worth assessing.

• Can a dental abscess go away on its own?

  No - an abscess indicates an active infection that requires treatment, whether through root canal therapy or, in some cases, extraction. It will not resolve without intervention and can worsen if left.

• Do I need to see a specialist straight away, or can my dentist help first?

  Your general dentist can manage many early-stage cases, and will refer you to a specialist endodontist like Dr Blewitt if the situation is more complex or needs specialist equipment.
