Individual Dental Insurance Schemes

[CAT777]

Any advise on that? Is it worth of getting one for individuals. It seems very diffucult to get dental insurance for individuals especially for EP holders in Singapore, most of the companies have various offers for a group insurance only or for citisens and PRs
The root canal treatment for my 2 teeth makes up the cost up to 2500 K (with the crown). And seems like more teeth need to be repared in the future; i was thinking may be it's more wise to get an insurance later

Any advise is appreciated
