Garzia Group spokesman Marcelo Antunez is calling the accident "minor" and says the concert will be held on Wednesday.
Antunez said Tuesday that Tyler was treated at a local hospital for cuts on his face and received two dental implants for the lost teeth.
He said the 63-year-old singer was "once again in the Bourbon hotel" recovering for the concert.
Antunez says it will be the first time Aerosmith has played in Paraguay and organizers expected more than 50,000 people will attend the concert.
The concert was originally scheduled for Tuesday.
