i'm afraid what you quoted in the brochure "Company:
Fabulous Smile Pre Ltd
Tel: 6884 5455
www.fabuloussmile.sgfabuloustan.livejournal.com
is one of those clinics where teeth whitening is done by non-dentists.
I'd advise against going to these "teeth whitening companies" because of several reasons:
1) Teeth whitening involves not just placing chemicals on the teeth, but also protecting the soft tissues (the gums, tongue, cheek etc) from damage from the chemicals. Obviously someone who is not trained as a dentist won't be well versed to handle that.
2) Not every case requires whitening. In certain cases, if the stains giving the discolouration is extrinsic in nature, other simpler procedures will be sufficient. In fact, whitening may just mask the problem and give rise to bigger problems in the future
3) A dentist will do a thorough examination prior to the procedure. You might require other more urgent treatment eg caries, gum disease etc. Just carrying out a whitening may give you short term results, but in the long run, when the problems become obvious (eg pain) the treatment required then will usually be more complex and expensive
4) from the prices quoted on the website, doesn't seem like its much cheaper than seeing a dentist.
Hope this answers your questions. Very Happy
