Maybe you've always wanted a beautiful white smile. Or your teeth have yellowed over time. Or you're not happy with the staining that results from drinking coffee, tea or red wine. Whatever your reason for wanting whiter teeth, you're not alone.

Just like we all have different hair and skin colour, people also have different coloured teeth. Some teeth are more yellow than others, while others yellow with ageing - there are many factors which can effect the colour of your teeth.

Surface stains and discolouration can be caused by:

• The natural ageing process
• Smoking, drinking coffee, tea, colas or red wine, and eating highly pigmented foods such as cherries and blueberries
• Accumulation of plaque and tartar deposits

There are many reasons for whitening your teeth, including:

• The boost to your confidence and self-esteem that comes from a great smile
• A younger appearance
• A special event such as a wedding, job interview or holiday
• To make a positive first impression on others
• To simply reverse years of everyday staining and yellowing

Whatever your reasons, remember that noticeably whiter teeth do not happen by chance! It is advisable to consult your dentist before beginning any whitening treatment. He or she can help you evaluate your best whitening options.
