Introduction to tooth whitening
Teeth whitening is a cosmetic treatment that is performed in order to give the teeth’s outermost layer, the enamel, a whiter colour and to remove the discoloration caused by various reasons.
The interest in tooth whitening has exploded in recent years and the range of different products and treatments is enormous. This can make it difficult to decide on what method to choose when one promises easier and better results than the other.
Are you a suitable candidate for tooth whitening?
What results to expect from teeth whitening is mostly determined by your condition.
Tooth discolouration due to medication, as well as teeth that suffer from genetic mineralization disorders require an extensive treatment. The results are often satisfactory, depending on the type and severity of the discolouration.
Tooth whitening is not recommended during pregnancy or breastfeeding, as studies have shown possible side effects on the fetus or child.
Individuals with sharp tooth pain, exposed root surfaces, poor brushing habits and thin enamel caused by erosion damage are advised to avoid dental bleaching since the risk of side effects such as tooth sensitivity can increase.
Heavy smokers should be aware that the effect of dental bleaching is considerably poorer. However, if you quit smoking, you can get good results, but doubled treatment time.
It is easier to whiten teeth with dicolourations that are brown-yellowish (warm colurs, such as age related changes), compared to discolourations that are in gray-blue tones (cold colours).
Teeth whitening of dental restoration and root filled teeth
Plastic repairs, crowns and bridges and other dental material in the mouth won’t be bleached. If they are placed in the front teeth, they may have to be replaced after the treatment. They are however durable.
Dead root filled teeth can also be bleached. However, using a different method than what is used for healthy teeth. The most popular method for bleaching of root filled teeth is a bleach that is applied inside the tooth. The bleach may need to be replaced a number of times to get the best results.
