1. Bleaching devitalised teeth

Usually the reason for the discolouration of non-vital teeth is badly performed root canal treatment in the past. Hence the first stage in the bleaching process is to perform the repeated root canal treatment properly this time. After ensuring the procedure has been concluded correctly (by means of an X-ray control, examination of the patient and interview) we can proceed with the bleaching.
The bleaching agent is placed inside the discoloured tooth after earlier making sure the canal is suitably safe. This procedure is usually repeated three times at short intervals. Later, a preparation ensuring an air-tight build-up of the tooth is placed inside the tooth. Two weeks later a filling can be made or a prosthetic restoration placed.

2. At home bleaching with splints

At home bleaching using night splints is performed after individual bleaching splints are made. Such splints are made by a dental technician based on an impression taken from the patient by a dental surgeon or hygienist.
The dental surgeon/hygienist gives the patient a special bleaching gel in tubes as well as precise instructions for use. The bleaching usually takes around 2 weeks. It can involve temporary sensitivity of teeth, especially to cold stimuli for a few days.

3. In-office bleaching using the BEYOND lamp

Such bleaching is performed by the dental surgeon/hygienist in the dental surgery. The entire procedure lasts roughly one hour. Two weeks before bleaching the patient should have his or her teeth professionally cleaned of dental calculus and deposits. He must also have all carious lesions treated or protected.
Prior to the procedure the patient’s gums are very carefully insulated (with a special light-curing material) against infiltration of the gel during the bleaching process. During the bleaching the gel is applied three times. After the procedure the patient may suffer short-term hypersensitivity (usually for up to a few hours).

For a few days after bleaching the patient should observe a “white diet” (avoid red wine, beetroot, coffee, tea, carrot juice and other coloured food products).
