Greetings, i understand your concern . Parasafe is safe to use for shorter duration.
But it is not a permanent solution for your toothache. As you have mentioned you are 6 months
pregnant, you should definitely visit a dental clinic for the treatment of toothache.
From 7th month till delivery, it is not recommended to get longer duration treatment .
May be your pain will increase after some days and you won't be able to get the treatment on that stage.
Next Steps
