Question
Last night, after my son had eaten a lot of candy, he started crying with a toothache soon afterwards.
Answer
Toothache caused by cavities can be relieved with painkillers and anti-inflammatory medication, but this does not cure the cavity, and pain may still occur in the future. It is recommended to go to the hospital for a dental filling as soon as possible to prevent the cavity from worsening. In daily life, one should pay attention to oral hygiene, brush teeth regularly, and eat fewer sugary foods.
