How Long Does Laser Teeth Whitening Last?

Teeth whitening

Teeth whitening is a cosmetic procedure that aims to lighten the color of the teeth to become whiter. It has recently become very popular among young men and women, especially since it is inexpensive and painless. It is known that the beauty of the teeth is the secret to the beauty of the smile. The teeth whitening process does not necessarily require going to the dentist's clinic. The process is no longer limited to the use of lasers. There are recipes from alternative folk medicine that have proven their worth and effectiveness in this field, and have even outperformed their counterparts in modern methods and techniques, especially since they do not weaken the teeth, and do not require the addition of chemicals that may harm them or the gums in the long term. If it does not succeed, it will never harm.

Laser teeth whitening duration

Teeth whitening results generally last between 18 months and a maximum of 3 years, but this period may be reduced to less than a year if the person is a smoker, does not brush his teeth daily, or drinks a lot of tea and coffee. As for the time it takes for the teeth whitening process using a laser, it is an hour that may be a little longer or shorter. As for the substance used, it is hydrogen peroxide, and its mechanism of action lies in converting the two layers of enamel into unstable atoms, to break down the atoms of the substances that cause tooth discoloration, which helps to lighten them.

Factors affecting the success of laser teeth whitening

Results vary from one person to another. Success for one person does not necessarily mean that the same results will be obtained for another. The factors that affect the difference in the success of the operation include:

  • The nature of the teeth, are they sensitive or strong?
  • The type of tooth to be whitened: is it a front tooth, a canine tooth, or a molar tooth?
  • Degree of yellowing of teeth.
  • The type of solution used.
  • The extent of the patient's commitment to the instructions and guidance of the specialist doctor.
  • The method used, is it laser, blue light, or whitening pen?

The difference between laser and blue light teeth whitening

  • Teeth whitening using laser is an ideal solution for those with sensitive teeth, especially since laser beams do not heat the tooth, while applying hydrogen peroxide used in blue light causes obvious pain for the patient.
  • The process of teeth whitening using laser controls the degree of whitening, as each tooth needs a certain degree according to its location in the mouth and its natural color.
  • The use of laser does not affect the internal structure of the tooth; in other words, it does not cause complications in the long term.
