tooth abcess

Hi again, hope you can help. My son who is almost 7 has got an abcess next to a milk tooth molar that is so decayed the dentist does not want to put a filling in.

The abcess has been there for a while and I found out when took him to a dentist about something else. He says it does not hurt at all. The dentist gave him a week of penicillin but nothing changed - no surprise there!A few days later I gave him Hep sulph C6 a few times - nothing, then tried Silicea C30 and he said that it feels good and the abcess is gone but it hadn't - maybe the remedy did something else??? Now am taking him to dentist who is going to give more antibiotics or remove the tooth and I don't like either option. Is there anything else I can try to get rid of the abcess?

My son has a lot of Phosphorus and Arsenicum characteristics.He reacts to full moon, sleepwalks and has a high need for security - does not like change for example complained how our home is so strange and everything is out of place when I had only swapped places of a few house plants! He gets angry easily, knows what he wants and can be generally described as speedy (also occasionally impatient which leads to anger).

Please help as I don't like antibiotics.
