Teeth whitening for a confident smile

Every one of us wants a beautiful smile which others envy. But not every one can smile the way they actually want for number of reasons and tooth discoloring is one of them. Advancement in modern dental treatment has offered a plethora of options for tooth whitening which is known as teeth bleaching.
Bleaching of teeth is done in several ways. However not everyone can go for teeth whitening for the following reasons:

  • Teeth with restorations , such as veneers or having been bonded with white fillings, cannot be whitened with hydrogen or carbamide peroxide. These materials do not whiten past the color they were originally made. The color of this type of restoration was determined by the surrounding teeth. If the surrounding teeth are whitened, the restorations will stand out and look artificial. Replacing old or discolored restorations will allow you to change their appearance.
  • Teeth that have internal staining, discoloration from developmental conditions or have been root canalled may not be affected by the typical whitening process. Internal teeth bleaching or permanent restorations may be an option to consider.
  • Natural tooth colors that are brown or gray in hue may not produce desired results. Typically, teeth with a yellow hue will produce the best results.
  • Pregnant women should avoid bleaching of teeth as the affect of chemicals on unborn baby are yet  not known to the medical practitioners.
  • People with hypersensitive teeth should stay away from teeth bleaching as this may increase their sensitivity.
Need of Teeth Bleaching
There are many reasons for whitening your teeth, including:

  •     The boost to your confidence and self-esteem that comes from a great smile
  •     A younger appearance
  •     A special event such as a wedding, job interview or class reunion
  •     To make a positive first impression on others
  •     To simply reverse years of everyday staining and yellowing
There are several ways of Teeth Bleaching like:
Whitening Toothpastes
All toothpastes help remove surface stains because they contain mild abrasives. Some whitening toothpastes contain gentle polishing or chemical agents that provide additional stain removal effectiveness. Whitening toothpastes can help remove surface stains only and do not contain bleach; over-the-counter and professional whitening products contain carbamide peroxide or hydrogen peroxide that helps lighten the color deep in the tooth.

Over-the-Counter Whitening Strips and Gels
Whitening gels are clear, peroxide-based gels applied with a small brush directly to the surface of your teeth. Instructions generally call for twice a day application for 14 days. Initial results are seen in a few days and final results are sustained for about four months.
Whitening strips are very thin, virtually invisible strips that are coated with a peroxide-based whitening gel. The strips are applied twice daily for 30 minutes for 14 days.
Whitening Rinses
Among the newest whitening products available are whitening rinses. Like most mouthwashes, they freshen breath and help reduce dental plaque and gum disease. But these products also include ingredients, such as hydrogen peroxide, which whiten teeth.
Tray-Based Tooth Whiteners
Tray-based teeth bleaching systems, purchased either over-the-counter or from your dentist, involve filling a mouth guard-like tray with a gel whitening solution -- which contains a peroxide-bleaching agent -- and wearing the tray for a period of time, generally from a couple hours a day to every day during the night for up to four weeks and even longer (depending on the degree of discoloration and desired level of whitening).
Though the desired level of teeth bleaching is a prerogative to many conditions of your teeth, whitening of teeth is done for a shiny radiant smile which takes your attention. So if next time if you are seeing a yellowish layer discoloring your teeth and considering teeth bleaching then we recommend you to consult your dentist before you go further.
