Types of teeth whitening and how they work

Daily oral hygiene is very important for health, but 2 out of 10 Spaniards do not brush their teeth with minimal frequency. It must be borne in mind that tobacco, certain foods and drinks make our smile lose its shine and spots appear. There are specialized toothpastes that can help keep white enamel for longer, but there are other methods, such as teeth whitening.

There are different types of whitening, but these will always be adapted to the needs of the patient. The simplest and fastest treatment is whitening in clinic, since each session lasts approximately one hour and the results are immediate. The process is based on covering the gums to protect them and using a hydrogen peroxide gel starts to whiten the teeth with the help of an intense lamp (LED or allogeneic) that accelerates the mechanism. The application of the gel is done in a splint that will be placed on the denture. During the whole process, the doctor and the patient always have to be protected with special glasses.

Treatment at home is also possible, but it always has to be after consulting the dentist and following their breaks. The technique will be the same, the gel will be placed in the splint and you will wait a while to remove it later. The treatment will not cause any pain and in the case that there is sensitivity in the teeth, it will disappear after the process.

Bleaching mixed is a mixture of the above. You should go to the clinic for photo activation with a cold light lamp, which will clear the teeth more intensely, then follow the treatment at home with splints and bleaching gel.

There is another type of whitening, the so-called internal whitening. Contrary to the previous ones, this type of treatment is not valid for all types of people. This process will be performed exclusively in patients with devitalized teeth. In endodontic, the nerve is usually killed and this causes the natural enamel to be lost. This method is painless and is usually performed without anesthesia.
