If you have a toothache, you should try to see a dentist as soon as you can. Sometimes, what is felt as an ‘ache’ is just tooth sensitivity, but more often a tooth ache is an indicator of something more sinister such as tooth decay or an infection. Whilst you are waiting for your dental appointment, rinse well and try to remove any food that may be trapped in that area (use floss or an interdental brush if required).
If there is a swelling, a cold pack on the outside of the cheek may help. Take appropriate pain relief as required (please do not place the tablets directly on the gums or teeth as this may cause damage to the teeth, gums or cheek. Instead, ingest the tablets as recommended on the packaging and ensure you do not exceed the maximum dose).
