Will the zpack be used for toothache?

Temporary: Measure at best. It buys you time but does not solve the problem and may hurt you in the long run if the bugs get immune to the drug so see your dentist soon.

Not usually: A toothache in itself may not require an antibiotic unless there are clinical findings and symptoms associated with an abscess or acute infection. A Z-pack is a dosed antibiotic regimen used to treat certain infections. It is not the antibiotic of choice for most dental infections.

Antibiotics: Antibiotics reduce swelling and spread of infection, but problem will come roaring back unless the infected tooth material is physically removed. That means root canal/crown or extraction/implant/crown. You can' toured this problem with a pill.
