What is the best method to deal with tooth pain at home until I can see a dentist?

Warm salt water rinses are very useful if you have swelling or some sort of infection, as salt water is a natural antiseptic and can reduce pain. Another temporary measure is taking over the counter painkillers, such as paracetamol or ibuprofen, as this will slightly reduce any pain. Always consult with a professional before taking any medication.
