Discoloration of the teeth can have different causes: In the course of time, nicotine, caffeine or tannin, which is contained in wine, are deposited in the crystal structure of the tooth enamel. Drugs (e.g. tetracycline) and trace elements (e.g. too much fluoride) can also cause stains. Finally, the individual tooth colour becomes darker with age. In such cases, bleaching treatment may be the right therapy. In any case, a professional tooth cleaning must be carried out before a bleaching treatment. In this way, the actual situation can be better assessed again and documented photographically.
Before teeth whitening your teeth should also be examined for their condition and health, because dark or yellowish tooth colors can also have pathological causes in individual cases or caries and leaky fillings must be clarified and treated beforehand. The state of health of the gums must also be examined. The bleaching agents only work on natural tooth substance, i.e. conversely, dental prostheses (crowns, partial crowns and bridges) will not react to the bleaching treatment.
The colour of even existing plastic fillings in the anterior region will not change. In such a case, the fillings should be replaced. For this reason, a treatment must be planned exactly in order to achieve an aesthetically pleasing result.
Long-term examinations have shown that professional bleaching does not usually damage the teeth. You also do not have to worry about your fillings, crowns or veneers, as the bleaching agent normally does not attack them. However, as already mentioned above, there may be differences in colour between the natural teeth and the new teeth, which may be planned anyway and would be adapted to the shade situation.
After the treatment, the teeth may become hypersensitive, but this will disappear by itself after a short time. Bleaching involves removing water from the teeth, which leads to hypersensitivity. As soon as the treatment is completed, however, the teeth quickly store the missing water again.
If you have opted for bleaching, your teeth should be healthy and free of tooth decay. We will be happy to advise you, even with home bleaching, to make sure that you have been able to clarify your questions comprehensively. So you can look forward calmly to the whitening of your teeth and the better life feeling connected with it.
