As the name suggests "Teeth whitening" is the method of improving the colour of teeth by removing stains from the teeth through a bleaching process and making them look whiter. By a simple procedure of scaling and polishing, a significant improvement in the colour of heavily stained teeth can be achieved.
In these days most of Glasgow cosmetic dentists suggest combination of the two procedures that is in-surgery teeth whitening system using laser and the other is that teeth whitening trays to be used in home for next few weeks. A combination of the two procedures provides both immediate and long-term whitening like laser whitening provides immediate results and the take home whitening kits provide results over a longer time scale. Both the procedures are based on a bleaching process using a peroxide based compound. Your Glasgow dentist may vary the strength of peroxide compound from 3 to 50% according to the need of the discoloured teeth.
If the percentage of peroxide in the compound is high then the bleaching compound is more powerful thus more effective in whitening the teeth but also the highly concentrated solutions can cause damage to the gum tissue. Your Glasgow Dentist saves your gums and lips from the bleaching action by coating with protective gel material during this procedure.
