Any ideas on how best to whiten teeth?
I suppose in the long run I might save up and get a proper whitening treatment at the dentist (anyone know how much this might cost?) but in the short term I'm wondering if anyone has tried anything that works...
I have some whitening gel stuff but no trays (I did have some but they were rubbish so I threw them away). I also heard baking powder is good...
Have you found any whitening toothpastes that work?
What foods/drinks should I be avoiding?
All advice appreciated!
