Hello there... the toothache is certainly due to the infected cavity...u need to visit the dentist to diagnose the extent of the infection...based on which further treatment can be planned. Take care !!
Although there are many causes of tooth ache, the most common causes are deep cavities leading to pulp infection and gum disease. For temporary pain relief, you can take any painkiller. I would advice you to visit your dentist so that exact cause of pain can be identified and complete treatment can be done.
