Teeth whitening is the process of removing stains from teeth and improving their colour through a bleaching process to make them look “whiter”.
For heavily stained teeth a significant improvement in their appearance can be achieved following a procedure as simple as a scale and polish from your nottingham dental hygienist.
Most Nottingham cosmetic dental practices offer a combination of in-surgery immediate laser teeth whitening and take home whitening kits with custom made trays. Both procedures are based on a bleaching process using a peroxide based compound which varies in strength (3-50% peroxide). The higher the % of peroxide in the compound the more powerful the bleaching compound is. This means it is more effective at whitening the teeth but at the same time has a greater potential to cause damage to the surrounding gum tissue. Your Nottingham Dentists usually use a shield to protect the gums during this procedure. This is the reason that home whitening kits usually have a low concentration of peroxide. The take home whitening kits provide more permanent results over a longer time scale whereas laser whitening offers immediate results. A combination of the two provides the perfect solution to both immediate and long-term whitening.
There are many different brands of professional tooth whitening systems, with the most popular systems being Zoom!, as featured on extreme makeover, Opalescence and BriteSmile.
Before any whitening procedure the Nottingham dentist or a hygienist will thoroughly clean the teeth, removing any surface stains and tartar. This procedure is commonly referred to as a scale and polish.
The next step will be for the Nottingham dentist to make a record of the shade/colour of the teeth before the procedure to show the patient the difference achieved after the whitening. This is either recorded using a tooth coloured shade guide/chart or by taking a digital photograph of your teeth. The area is then prepared for the procedure. The bleaching compound usually contains a high concentration of peroxide (15-50%) and so the dentist will usually place some form of protection around the gums so that only the teeth are exposed to the compound. This may involve covering the gums with rolls of cotton or a protective gel material that hardens once applied to the gums.
A cheek retractor is used to keep the lips and cheeks away from the teeth. Eye protection is also provided to prevent any damage to the eyes from the laser used or any accidental splashes of the peroxide. Many cosmetic practices now offer DVD glasses so that the patient can watch a movie during their treatment!
