| There is other tooth whitening procedures such as laser whitening or "power whitening". During this treatment a light or laser is shone on the teeth to set in motion the chemical. The light quickens the chemical reaction of the whitening product and the alteration of color can be achieved more rapidly. Laser whitening can make teeth up to five or six tints lighter. The laser whitening procedure typically takes about one hour. What About Home Tooth Whitening Kits? Home tooth whitening kits are relatively cheaper. Nevertheless, as tooth whitening is a complex procedure you should only have it done by a dentist after a detailed examination and evaluation of your teeth. Over-the-counter tooth whitening kits sold in the UK are not compulsory as they usually include only a small concentration of hydrogen peroxide. The legal limit in the UK is 0.1% of hydrogen peroxide and useful bleaching products need to have about 3.6%. This means that home tooth whitening kits will not be able to lighten your teeth distinctly. In addition, some home tooth whitening kits enclose mild acids and others are abrasive. This can cause ulcer and harm to the gums if the product is not used appropriately. What About Whitening Toothpastes? There are more than a few whitening toothpastes on the market. Even though they do not influence the natural color of your teeth, they may be effective at removing staining and therefore may improve the overall appearance of your teeth. Whitening toothpastes may also help the effect last, once your teeth have been professionally whitened. How Much Does Professional Teeth Whitening Cost? Generally you cannot obtain whitening treatments on the NHS. Private fees will differ from practice to practice and region to region. Laser or power whitening will be more costly than professional bleaching.
Demand a written estimation of the charge before you begin any tooth whitening treatment.
