Hi XXXXXXX

Thanks for writing in.

Amoxicillin single dose of 2-3g is given before any dental procedures as prophylaxis against endocarditis, for dental abscess, severe urinary or respiratory tract infections, listerial meningitis. So usually at the dosage, which you have ingested, the amoxicillin should not cause any problems. Drink lot of water, which will assist in excreting the drug through urine.
Over dosage can cause hyperactivity, rash, diarrhea, agranulocytosis, renal failure etc. If you feel any such symptoms, I would suggest you to see your doctor immediately.

Do write back if you have follow up queries to ask.

Regards.
