Hey hun
I'm trained to do teeth whitening and have had my teeth whitened.
It's a common misconception that the laser whitening is better than a home kit, it's not, just far more expensive!
There r 3 ways 2 whiten your teeth:
1) Just with laser
2) Laser then using the home kit for 6 days
3) Using the home kit for 2 - 3 weeks
The worst result will be option 1. Purely using the laser will not get ur teeth as white as possible. No 2 and 3 will get u similar results, but no 3 is the best option.
The main differences between 2 and 3 is time and money. If u go with the laser then u don't have to use the home kit for so long, some people find the home kit a pain.
Also if u have sensitive teeth, 3 is the best option. When using the laser u put a much stronger solution and it can b painful for the 24 hours afterwards for some people.
PM me if u want a good home kit I recommend, the dentist ones r really expensive because they make u fitted trays for your teeth. The home kits come with trays that u mould 2 ur teeth which do the job perfectly.
Also, a lot of people don't tell u this because they want u 2 go back. Once u hav got ur teeth as white as possible, it's like a tan, it's best to keep it top uped so it never fades.
I was told to whiten my teeth for one night a month at home using the trays to keep my teeth white. But I think once every 6 months is fine.
Hope that helps
