Ingredients of whitening gel for sensitive teeth – Expert 20%

Applying precisely selected concentrations of potassium, glycerol, and carbamide released during the whitening process reduces post-treatment tooth sensitivity, which is moderate and occurs only sporadically. The combined effects of these substances in many cases completely eliminate post-treatment tooth sensitivity.

Tooth discolouration is a frequently occurring symptom of fluorosis – an illness caused by excessive amounts of fluoride ions absorbed by an organism. Fluoride is a microelement which improves the condition of the enamel, but, in excess, can lead to adverse health effects. Due to the fact that Dr. Martin Schwarz EXPERT 20% does not contain fluoride, whitening treatment does not increase the risk of the occurrence of fluorosis.

Dr. Martin Schwarz EXPERT 20% whitening gel prevents acid-induced demineralization of tooth enamel which is observed during treatment using products with a pH lower than 7. The effect of enamel demineralization in the case of applying gel Dr. Martin Schwarz does not occur. Reduced the risk of fluorosis, counteracting drying teeth and lack of, or minimal level of post-treatment discomfort – make this whitening gel an ideal solution for people with sensitive teeth.

Tips on how to achieve the best whitening results while using Expert 20% teeth whitening kit at home.

Choose which teeth to brighten

Whitening kit can be used in different ways according to individual expectations. Expert 20% gel can be applied to the dental trays in order to cover all teeth, but many experienced customers prefer to apply the gel on only first eight teeth (counting from 4 to 1 and 1 to 4 of each arch). Whitening selected area of teeth arches only allows saving the whitening preparation for additional sessions. In addition, brightening the colour of wisdom teeth – or other teeth which are difficult to see – might not be visible & possible to be noticed by others.  

Replace dark fillings

Carbamide peroxide used in Expert 20% formula demonstrates significant whitening properties but does not whiten fillings and porcelain crowns of the teeth. Whitening treatment performed on teeth with dark fillings in visible areas can actually create an obvious, undesired contrast. In order to achieve the best whitening results, it is recommended to replace old fillings with the brighter once and undertake teeth whitening procedure. 

Adjust eating habits

Besides genetic related factors, a shade of the teeth depends on a handful of other determinants including consumed product, oral hygiene, and oral habits. Consuming items rich in intensive, organic pigments such as red wine, coffee, tea, smoking cigarettes, etc. – negatively affect maintaining a bright colour of teeth. The teeth are the most vulnerable to those products especially right after whitening treatment and between whitening sessions. It’s strongly recommended refraining from consuming such products especially during the course of whitening treatment and 1-2 days after finishing the whitening cycle. 

Use custom made dental trays

Teeth whitening treatment with the use of professionally adjusted, custom made dental trays – helps to minimise the risk of gum irritation and retain whitening gel. Custom made dental trays are precise impressions of the teeth arches that when applied with the gel – keep the whitener closely to the teeth surface. Using custom made dental trays provides fine whitening results and prevent the gel to overflow on gums – reducing by that the risk of gum irritation.
