Therefore, many people will choose to use laser teeth whitening to whiten their teeth. So how long can laser teeth whitening last?

1. How long can laser teeth whitening last?

1. Cold light whitening is to make a neutral whitening agent. The light source emitted by the whitening light gradually penetrates into the teeth, removes stains and achieves a whitening effect. The chemical reaction of whitening teeth can be produced in about 45 minutes. The hydrogen peroxide used in the treatment has been safely used on teeth for more than 100 years, and most of the ultraviolet and infrared rays have been filtered, so it is irradiated on the teeth in a cool way. In other words, the treatment process is very safe and the whitening effect can last up to 2-3 years.

Pay attention to oral care after treatment, try to drink less coffee, cola, soy sauce and other foods that are easy to stain, brush your teeth in time after eating pigmented foods, adhere to correct oral care and pay attention to oral hygiene, the effect of teeth whitening will last for 3-5 years.

2. Benefits of Laser Teeth Whitening

Laser teeth whitening is achieved by using a laser whitening device to output a unique wavelength of a semiconductor to excite the teeth whitening gel that has been applied to the tooth surface in advance. The laser can then selectively act on the pigment particles in the teeth, catalyzing the gel to react with the pigment, thereby removing tartar, plaque, pigments, smoke stains and soft stains, and restoring the teeth to whiteness.

Generally speaking, ordinary teeth whitening methods can only remove surface attachments of teeth or cover up tooth discoloration, but cannot fundamentally change the original appearance of teeth. Laser teeth whitening has made a breakthrough in this regard. It does no damage to teeth and greatly reduces the possibility of tooth overheating or sensitivity. The effect is incomparable to that of ordinary teeth whitening methods.
