Introducing: Dr. Kam, Your Professional Dental Surgeon in Central
Thinking of bleaching your teeth? Here are some info you need to know.

Most of us would like to have whiter teeth these days. If you drink coffee, red wine or smoke, chances are you would be looking at some kind of teeth whitening solutions. To make sense of the options available out there, we thought we’d ask an expert in Hong Kong.
Dr. Andrew Y. L. Kam, dental surgeon with an office on D’Aguilar Street, Central, has agreed to lay it all out for us. He says whitening treatments are really popular in Hong Kong. According to Dr. Kam, there are basically 3 types of procedures. They are: bleaching, porcelain veneer and ceramic crown.
1. Home bleaching
This is where your dentist will customize a mouth tray for you. What you need to do is to apply the bleaching gel (e.g. 10% carbamide peroxide) into the tray and wear it overnight. Usually the whitening result will be obvious in 2 to 6 weeks time.
2. In-clinic bleaching using blue light or laser
This is a procedure you go to your dentist for. The bleaching gel that dentists use has higher concentrations of whitening agents (e.g. 15%, 30%, 35% hydrogen peroxide). For faster results, bleaching with blue light or laser will whiten your teeth within an hour or so.
“Personally, I find that a combination of clinical treatment where you bleach your teeth at the clinic with either laser or blue light and then continue bleaching at home, gives the best result.” says Dr. Kam.
Next week, we’ll check back with Dr. Kam on the other 2 procedures: porcelain veneer and ceramic crown. If you have any questions now, feel free to post questions here or give Dr. Kam a call to arrange a consultation.
