Have looked at a few old threads about this but would like some up to date advice from anyone who has recently tried to whiten 
I have a graduation and wedding coming up in the summer and would really like to get started on improving my tea stained gnashers!
I understand the most popular options are:
- Crest whitening strips
- Dentists bleach trays
- Laser
I’m torn between 1 and 2. I’ve discounted 3 as it doesn’t have great reviews unfortunately.
My dentist is offering the trays and gel for £350 and said the gel can be bought online for much cheaper than in-clinic thereafter (isn’t it nice when they’re honest?!).
Crest strips will have to be purchased from the US + shipping.
Any thoughts/advice/tales of horror/success stories?
