Love my dentist, wouldn't give up even when ins. changed, had one once, in a similar situation w/upcoming vac. started a root canal, had told him we could wait. hurt the whole time, lots of warm salt water seemed like the only thing that helped, But had another waited till mon to call, he told me not to, because they have on call weekend buddies. who knew.
Hope your tooth feels better, definately recontact!!
