To anyone who has had teeth whitening done, what option did you choose and what experience did you have?
I've used Crest Whitestrips Supreme before and although they whitened my teeth, I have to say the application of them is tricky and they caused me chronic sensitivity. I was practically rattling from painkillers and was constantly foaming at the mouth from Sensodyne.
These days I use custom fit trays and a moderate strength (20% carbamide peroxide) professional whitening gel, usually Opalescence PF or Philips ZOOM! DayWhite. The thing is, I dealt directly with the Dental lab so my trays were closer to the wholesale price rather than the retail price which is about £200. You order a self impression kit online, take your own impressions which is a piece of piss when you've watched a decent amount of YouTube videos and have familiarised yourself with the process and technique. You post the impressions back and within about seven days or so, they send the trays back to you. The gel I use which is actually the same as what a Dentist would prescribe is also sold at a wholesale price, so all in all the total cost for a beginner who wanted to go down this route would be approx £100 - £130 depending on the type of retainer (there's a few to choose from) and the quantity of gel you buy. Once you have the tray though, it's useable for years if it's taken care of properly. The same as what I have just described costs somewhere in the region of £300 - £400 from a Dentist.
I know that in office bleaching like ZOOM! is extortionately priced and sometimes gives disappointing results, of course, I will be happy to be corrected on that if that's not entirely true.
