@Farah1 - I think you bring up an excellent point. Thank you for posting. Glass ionomer cements are much better than metal cements. Using them instead of metal cements makes the thought of filling in a cavity much less scary.
I have a seven year old son. While I try to make him understand the importance of good dental hygiene, it is still a struggle getting him to brush his teeth regularly. Sure enough, when he last visited the dentist for his six month check up and cleaning, the dentist found a few cavities.
I was devastated. When I was his age, I too had cavities that needed to be filled. My childhood dentist only used metal fillings. So when I returned to school the next day after getting my cavities filled, my classmates poked fun at me. I did not want my son growing up insecure about his smile like I did.
Thankfully, his dentist assured me that he would be using a glass ionomer cement that would closely match the color of his natural teeth. This was quite a relief to me. I am glad dental care has advanced since the time I was a child.
