24-48 hours: Typically most antibiotics can take between 24 and 48 hours to reach therapeutic strength in the body. It can also be dependent on how extensive or extreme the infection is.

Usually 2 Days: A regular tooth infection normally shows signs of significant improvement within 48 hours. However, you said "major, " so it might take a bit longer. If you don't notice a huge improvement within 2 days, it's always a good idea to see your dentist again and perhaps add another antibiotic prescription to what you're currently taking. Don't wait too long & allow the infection to spread or get worse.

Differs: Generally after 24 hours of treatment you should begin to affect the infection. However all people respond differently, and it depends upon the severity and location and duration of the infection. Good luck.

Depends: Three things required to treat infected teeth are antibiotics, removing the cause of the infection and your body's defense mechanisms. An effective antibiotic takes 24 to 48 hours to work, but you may need another medication if this is not reducing the infection.

Nope: If you have an abscess, the antibiotics treat the bacteria outside the tooth. You will need root canal therapy to treat the bacteria inside the tooth. Please see ur dentist for comprehensive care.
