While you're having root canal treatment, avoid chewing or biting down on hard foods until the treatment has been completed.

In some cases, this may be after several visits to the dentist.

After your final treatment, your restored tooth shouldn't be painful, although it may feel sensitive for a few days. Over-the-counter painkillers, such as paracetamol or ibuprofen, can be used to relieve any discomfort.

Return to your dentist if you continue to experience pain or swelling after using painkillers.

Aftercare

After root canal treatment, clean the tooth in the same way as your other teeth and visit your dentist for check-ups as often as they advise.

Following the advice below will help ensure your teeth remain clean and healthy: 

• Brush your teeth twice a day, in the morning and evening.
• Spend at least two minutes brushing your teeth each time.
• Always use fluoride toothpaste.
• Use a small toothbrush so you can reach your back teeth, and use no more than a pea-sized amount of toothpaste.
• Flossing can be an effective way of cleaning the gaps between your teeth.
• Don't brush too hard because it can damage your gums.
