Assuming 400mg/5mL: 500mg (1.25 teaspoons) every 8 hours for 5 full days. But that's just the recommended dose. Your Dentist, in concert with your Pediatrician, the people who know your child best, may have different dosage recommendation.

See below: The dosage for a 5-year-old child weighing 40 pounds is about 900 mg of amoxicillin as one dose 30 to 60 minutes prior to the dental procedure.
