Малайзия

Aloha from Hawaii!
I am Nadia.
I will stay in KL 3 weeks on my vacation.
I have heard here is pretty cheap medical, and dental care.
Could some one give me a tips where to go for a dental treatment?
Can I by here some medical/dental insurance to cover my expenses?
I am staying at Crown Plaza Hotel, close to Twins Towers.
I will appreciate it,

Thanks
