Teeth whitening products – that guarantee to make your grin brighter – might also be causing tooth damage, a investigate has found.

Scientists during Stockton University in a US found that hydrogen peroxide, a active part in over-the-counter whitening strips, can repairs a protein-rich dentin hankie found underneath a tooth’s protecting enamel.

The tooth is done of 3 layers: a outdoor tooth enamel, an underlying dentin covering and junction hankie that binds a roots to a gum.

Most studies of whitening strips have focused on tooth enamel, that contains really small protein.

The group focused on dentin, that creates adult many of a tooth and has high levels of protein, many of that is collagen.

It is good determined that hydrogen peroxide can dig a finish and dentin. Previous work by a researchers showed that collagen in a dentin covering decreased when teeth were treated with whitening strips.

“We sought to serve characterize what a hydrogen peroxide was doing to collagen. We used whole teeth for a studies and focused on a impact hydrogen peroxide has on a proteins,” pronounced Kelly Keenan, associate highbrow during Stockton University.

The researchers demonstrated that a vital protein in a dentin is converted to smaller fragments when treated with hydrogen peroxide.

In additional experiments, they treated pristine collagen with hydrogen peroxide and afterwards analysed a protein regulating a jelly electrophoresis laboratory technique that allows a protein to be visualised.

“Our formula showed that diagnosis with hydrogen peroxide concentrations identical to those found in whitening strips is adequate to make a strange collagen protein disappear, that is presumably due to a arrangement of many smaller fragments,” Keenan pronounced in a statement.

The researchers indicate out that their experiments did not residence either collagen and other proteins in a teeth can be regenerated, so it is different if a tooth repairs is permanent.

Next, they devise to serve characterize a protein fragments expelled when collagen is treated with hydrogen peroxide and establish if hydrogen peroxide has a same impact on other proteins in a teeth.
