Is it permissible to use a pill for severe headache caused by teeth during fasting in Ramadan?

Severe headache permits breaking the fast in Ramadan, especially if fasting exacerbates it. It is permissible for the afflicted person to break their fast to take medicine, eat, and drink, in order to alleviate the headache. They must make up the days they missed after Ramadan, for Allah Almighty says: (And whoever is ill or on a journey - then [he is to fast] a number of other days).
