Wisdom tooth pain is usually due to inflammation of the gum over the erupting tooth.
This is often made worse by the trauma of biting, so introducing a soft food diet will help with the pain.
Most flare-ups can be managed with good home care and should settle within in a few days to a week.
It is important that you stick to a very thorough cleaning routine, even if it is painful to brush the affected area, as this will encourage healing.
Using a product such as Corsodyl mouthwash will help with alleviating pain but avoid using for longer than a week as it may cause staining of the teeth.
Warm salty mouthwashes can also help with alleviating pain.
If you have difficulty swallowing, swelling in your face or cheek or difficulty opening your mouth, please call your dentist for advice. You may need antibiotics if an infection is spreading.
