My 3.5 year old son hass cavities. There are 4 on the bottom and I couldn't get a good look at the top. They are on the back teeth. I feel so horribly guilty, like I haven't taken care of him properly. I've never had a cavity in my life! Now what do I do? I don't want him to have metal fillings. And how in the world would they do that kind of dental work on a 3 year old? He gets hysterical when we try to put garlic oil in his years, totally hysterical, screaming like he's terrified. I am so stressed out and sad. Not to mention the fact that we don't have the money to pay for the work. But we'll have to figure it out.
