Teeth whitening is a usual routine today. People always try to find time to go for a quick bleaching treatment. Actually, teeth whitening treatments are so popular that celebrities do their best to look the brightest smile.
People love teeth whitening products and this is largely due to the fact that dental bleaching treatments are very effective and safe nowadays with very low risks involved. In the past, acids and abrasives were used in whitening treatments as the only way to treat stains in the enamel. Evidently, these methods were not good, causing damages and facilitating the appearance of stains. For this reason sessions were limited. It was necessary to protect teeth from so invasive treatments.
Here is when the most effective bleaching agents play an important role. Carbamide and hydrogen peroxide molecules are able to get into the small pores to remove the stain molecules. This “breaking up” either makes the stain molecules small enough to escape the enamel, or it changes the structure so it reflects light differently – the stains become invisible, allowing the natural color of the tooth to shine through.
In the last years, dentist make use of blue and laser lights to facilitate the effect of these compounds on the stains. Blue light has a great property that activate the molecules of these bleaching agents and help them to work faster. This way, treatments never take more than 10 minutes. That makes modern treatments more convenient, cheaper, faster and less harmful to gums and teeth than old methods.
Nevertheless, these modern treatments make your enamels more porous and make them more sensitive too, causing pain and discomfort to hot or cold foods and drinks, so it is important for you to consider these downsides before deciding how fast you want to whiten your teeth.
Many people consider that laser teeth whitening treatments don’t bleach teeth more than regular treatments do. Since these treatments increase porosity in enamel they give a temporary brightness to the teeth. However, the effect disappears after a week when holes get close and results are not different from a non-accelerated method. Besides, more porous teeth increase the chance to get new stains so you should avoid eating too colored food for a week or so. Some people prefer accelerated treatments despite the effort involved, but sometimes going through a gradual process could be the right answer.
