If you develop a toothache, it is best to contact the clinic and arrange an appointment so the cause can be properly assessed. Tooth pain can have many causes, including decay, infection, cracks, gum problems, or clenching and grinding.
While waiting to be seen, try to avoid chewing on the affected side. Over the counter pain relief may help temporarily if appropriate for you, but it should not be relied on as a long term solution.
If the pain is severe, worsening, associated with swelling, or affecting your sleep, this should be assessed as soon as possible.
Early assessment often allows problems to be managed more simply and helps reduce the risk of complications.
