What is Tooth Whitening

Any procedure that lightens a tooth’s color is called tooth whitening. The tooth’s color can be lightened by a chemical reaction or by physically removing the stain.

Here, bleaching is defined as the chromogens’ chemical breakdown. The majority of whitening products contain hydrogen peroxide (H2O2), which comes in the form of carbamide peroxide or hydrogen peroxide.

Hydrogen peroxide is released when carbamide peroxide, a stable complex, comes into contact with water. Most tooth whitening products use hydrogen peroxide because carbamide peroxide makes hydrogen peroxide.

Process of Tooth Whitening

In order to safeguard the gums, a rubber dam is placed over your teeth, and a bleaching agent is applied to them.

The chemical is then activated by shining a light or laser on the teeth. The light accelerates the whitening product’s reaction, allowing for a quicker colour change.

There are various teeth whitening products available too and they are:

  • Whitening toothpastes: They are the same as normally available toothpaste but contain gentle polishing or chemical agents that provide additional stain removal effectiveness.


  • Whitening gels: Whitening gels are clear gels that are based on peroxide and are applied directly to the surface of your teeth with a small brush.


  • Whitening rinses: They freshen breath and reduce dental plaque and gum disease, like most mouthwashes. However, some of these products also contain ingredients that whiten teeth, such as hydrogen peroxide.


  • Tray-based teeth whiteners: Include filling a tray resembling a mouth guard with a gel whitening solution containing peroxide. The tray is worn for a certain amount of time, usually from a few hours a day to every night for up to four weeks or longer.


What does sensitivity means

Tooth sensitivity is tooth pain or discomfort in response to particular stimuli, like hot or cold temperatures.

It can affect one tooth, several teeth, or all of a person’s teeth, and it can be a temporary or ongoing issue. Sensitive teeth can be caused by a variety of things, but most of the time, they can be easily fixed by changing how you brush and floss.


Causes of Sensitivity:

  • Eroded enamel:- The tooth’s dentin is exposed when enamel wears away. As a result, your teeth become less protected and become more sensitive. Practice good oral hygiene by brushing and flossing on a daily basis and going to the dentist on a regular basis to prevent enamel erosion.


  • Decay of tooth:- Pain and sensitivity can be brought on by the breakdown of the tooth structure brought on by the acids produced by the bacteria in plaque. As a result, regular oral hygiene and avoiding sugary foods that encourage bacterial growth are essential.


  • Brushing pattern:- Too much pressure or a hard-bristled toothbrush can damage the enamel and cause gum recession.


  • Consumption of food items:- Alcohol, sour candy, and acidic foods like soda should be avoided because they can erode enamel and increase the likelihood of sensitivity. Instead, choose water, cheese, fruit, and vegetables, which are all good for your mouth. If you do end up eating acidic food, wait at least an hour before brushing your teeth because the acid weakens enamel.

Tooth sensitivity

How to avoid tooth whitening sensitivity:

  • Use toot-paste with a desensitizing component:-  About 10 days before your procedure, start using a toothpaste that makes your mouth less sensitive. These toothpastes will assist in preventing pain signals from travelling from your tooth’s surface to its inner nerve. To get the most out of the toothpaste, leave it on the surface of your teeth for a few minutes before rinsing.


  • Apply a desensitising gel:- this should be done. After the recommended amount of time has passed, rinse your teeth with water.


Relation between Tooth whitening and sensitivity

After teeth whitening, one possible side effect is tooth sensitivity, which is typically brought on by the bleaching solution. Minerals in the enamel may be removed by this solution, causing the teeth to become temporarily porous and exposing microtubules.

And this can be taken care by: 

  • Use toothpaste with a sensitive formula and a toothbrush with a soft bristle.
  • Rinse and brush with fluoride-based products.
  • Eat and drink at room temperature.
