teeth cleaning
The most practical teeth bleaching process uses hydrogen peroxide as the main agent to whiten the teeth. While there are simple toothpastes on the market that contain abrasives to remove the outer layer this would not be suitable for people who have deeper discolored teeth problems. If your problems are not from the result of smoking, drinking coffee or tea then you will need a more robust whitening system beyond the capabilities of whitening toothpaste. One of the most common reasons for teeth discoloration is the excessive drinking of coffee, tea, soft drinks such as colas, wines and spirits over a long period because these contain tannins. Tobacco is another reason though this is now on the decline as less people smoke. This is because the pulp chamber, or nerve of the tooth, is enlarged until this age. This basically means you have a tray fitted that matches your teeth shape exactly. The whitener solution is placed into the tray and you place in your mouth before you go to sleep so that the process works throughout the night. More powerful whitening solutions take less time so you may only need to wear the night guard system for 1-hour or so. Anyone allergic to peroxide (the whitening agent) should not use a bleaching product. The length of time you would need to wear the guard would depend on how strong the solution was. Again you need to be careful with over use and so it is imperative that you follow the instructions that came with the bleaching kit so that you have the best chance of positive results and also avoid any negative side effects.
