A root canal infection can return even after treatment. Spotting the signs early helps prevent more pain and damage. If you have had a root canal before and feel discomfort, knowing what to look for can help you act quickly. This guide explains how to recognise symptoms of a root canal infection from home. If you notice any of these signs, a Kellyville Dentist can confirm the issue and recommend the right treatment.
1. Ongoing Pain
Pain that lasts or returns after a root canal may signal infection. It may feel sharp, dull, or throbbing.
Tip: If the pain gets worse when you chew or press on the tooth, infection is likely. Make a note of how often the pain occurs and its intensity. Book an appointment with your Kellyville Dentist if the pain does not improve within a day or two.
2. Swelling Near the Tooth
Swelling near the treated tooth is another warning sign. It may appear as a lump on the gum.
Tip: Look for puffiness around the tooth, jaw, or cheek. If the swelling increases or feels warm, it may indicate infection. Your may need to take an X-ray to check for deeper infection.
3. Bad Taste or Smell
A root canal infection can produce pus. This leads to a bad taste in the mouth or foul-smelling breath.
Tip: If you notice a bitter taste that does not go away, or a strong odour, the tooth may be infected again. Call to arrange an inspection.
4. Gum Boil or Pimple
A small pimple on the gum, often filled with pus, may appear near the affected tooth. It might leak fluid or come and go.
Tip: Check your gum line regularly. If you see a bump that bursts or drains, it’s a sign to contact as soon as possible.
5. Tooth Discolouration
An infected tooth may change colour. It may look darker than the rest.
Tip: If your root-treated tooth starts turning grey or brown, it could mean the nerve has died or an infection has returned. A can help determine if retreatment is needed.
6. Tenderness or Pressure
A root canal infection can make the tooth feel sensitive to pressure. Chewing or even touching it may hurt.
Tip: Try biting down gently on different teeth. If one tooth feels more tender, infection may be present. Don’t delay visiting a Kellyville Dentist for a check-up.
