Thanks for the ideas Carang. I guess the kids might like them, although I personally think it's gross! I've googled fear factor parties and it seems it's a huge hit among pre-teenager kids. Hmm, I might give it a try ...
Rani, we are with Dr Ma at Bayley and Jackson in Central since August 2009. I would definitely recommend him. I had taken my son to 2 or 3 other orthodontists and Dr Ma is the only one who has explained ALL the options to me, with pros and cons in each case and in a long term perspective. We sat in his office for over an hour to talk about it (with no charge!). He is very honest. Unlike some others, he has been neither alarmist nor pushy to start treatment. After less than a year now, I can see big improvements.
If you need more info, I'll be glad to share.
