Welcome to just answer.
Z-Pack or Azithromycin is in a group of drugs called macrolide antibiotics. It is mainly used to treat infections such as respiratory infections, skin infections, ear infections, and sexually transmitted diseases.
Amoxicillin is one of the first antibiotics that we prescribe for dental infections. It normally takes between 24 and 48 hours before its effects are noticeable.

If you happen to be allergic to penicillin, the second choice is Erythromycin. Read more about this drug here http://en.wikipedia.org/wiki/Erythromycin
I would also like to emphasize the importance of combination of this drug with another antibiotic called metronidazole. The antibiotics chosen to be given for the dental abscesses should also have broad-spectrum coverage, and therefore combination therapy may be required. Read more about it here in a link: http://www.bsac.org.uk/pyxis/Head_and_Neck_Infections/Dental%20sepsis/Dental%20abscess/Dental%20abscess.htm Abscesses are frequently polymicrobial on culture, when we culture the abscess from drained material we can find that several species are isolated from the abscess. Therefore it becomes necessary to prescribe more than one antibiotic.This is to ensure that all possible causative agents will be targeted effectively. So a combination of Metronidazole(400mg) is also given with amoxicillin (500mg ) is given for dental abscess.. Read more about this drug here: http://en.wikipedia.org/wiki/Metronidazole
You can also start with warm saline rinses- A very effective way in reducing abscess /swelling is rinsing frequently with hot salt water solution- You can dissolve ½-teaspoon of salt in 8 ounces of water as hot as you can tolerate without burning the mouth,and rinse for two minutes every four hours, this will provide you relief. This will facilitate abscess drainage by softening the tissues around the infection.
