Common questions
How long does the appointment take?
Around an hour to ninety minutes, depending on the system used.
Will it make my teeth sensitive?
Some sensitivity is common for a day or two afterwards and usually settles on its own.
How long do results last?
It varies. Whitening fades over time, especially with coffee, tea, red wine or smoking.
Does it whiten fillings or crowns?
No. Whitening only lightens natural teeth, so existing fillings or crowns keep their colour.
