What is the difference between teeth whitening and bleaching?
Teeth whitening can just restore your tooth’s natural hue by only getting rid of the dirt and stain deposited on it. However, teeth bleaching can make your teeth whiter beyond its natural color.
In this sense, the regularly used toothpaste can also be regarded as a tooth whitening agent. While sometimes, the tooth whitening agents are also referred as tooth bleaching agents.
How to bleach your teeth?
The carbamide peroxide or hydrogen peroxide content enters into your tooth enamel and bleach the discolored part accumulated in the dentine region, and hence, provides an additional white effect to your teeth.
The whitening effect brought about by the bleaching agent can last for a year, but its effect can differ with changing the lifestyle of a person. Excessive intake of coffee, tea, red wine, smoking and consuming other dark colored food items can minimize the teeth whitening effect.
If your dentine region is stained resulting in complete teeth discoloration inside out, then it is recommended to perform an internal bleaching.
What are the disadvantages of tooth bleaching agents?
Gel bleaching along with a high-concentration oxidizing agent can harm the exposed tissues, which can discolor or bleach mucous membranes, which further results in chemical burns.
Excessive teeth bleaching with the teeth whitening products that promise a major change in your teeth color in a little period of time is considered to be damaging.
If you have sensitive teeth, then avoid bleaching because your tooth enamel could get severely damaged.
Bleaching can often cause tooth sensitivity to hot or cold food and beverages.
By performing bleaching, you are most at risk of developing tongue cancer.
Various studies have shown that using a high concentration of peroxide with the bleaching agents can cause gum irritation, but the irritation persists just for about 3 to 4 days.
Children under the age of 16 should never try bleaching because their dental pulp region is large until this age. Under such situations, if bleaching agents are used, then it can increase the pulp sensitivity causing mild pulpitis. In addition, bleaching is not advised for pregnant and lactating women.
The FDA approves bleaching agents having less than 16 percent carbamide peroxide and less than 6 percent hydrogen peroxide as safe to use.
Once you perform teeth bleaching procedure, you may get satisfaction about the major change in your teeth’s hue. However, the results can differ from person to person. Before you start on your journey of making your teeth whiter, check with a dentist. The dentist would consider your previous medical history to confirm if tooth bleaching agents are safe for you.
