Teeth whitening at City Dental Leeds

How does teeth whitening work?
First of all, we take an impression of your teeth so that custom-made trays can be built for your individual bleaching procedure. A special whitening gel is then placed within these comfortable trays and fitted snugly over your teeth. As the carbamide peroxide in the gel is broken down, oxygen enters the enamel and dentine of your teeth to give a bright, whitening effect by bleaching out discolouration. The structure of your teeth is not changed, they are simply made whiter.

Side effects?
Side effects are unlikely, although a small number of people could experience increased sensitivity to heat or cold during whitening. But this is only temporary, and can usually be treated with ibuprofen or another pain relief product. Usually, this sensitivity disappears within 48 hours of the whitening process. It is best to avoid very hot or cold drinks within 48 hours of your whitening treatment.

Does whitening last forever?
The results may be permanent although the duration of your whitening procedure does depend largely upon you. Take care to practice good oral hygiene and brush normally, especially after consuming staining foods or beverages. Your results could last for years. However, if you use coffee, tobacco and red wine on a regular basis, you may need periodic top up treatments.
