Teeth Whitening

Teeth Whitening is short-timed procedure either as an in-office treatment by a dentist or by using at-home teeth whitening methods. A protective gel is applied for gingival protection and then the bleaching agent - hydrogen peroxide or carbamide peroxide - is spread all over the teeth. After some time it is rinsed off and the process is repeated 3-4 times.

1. Teeth staining – types and causes

:diamond_shape_with_a_dot_inside: Teeth whitening is required mostly when teeth do not remain in their original color. Before heading towards the teeth whitening facts and procedures, first, you must be knowing the reasons for teeth discoloration or teeth staining.

:diamond_shape_with_a_dot_inside: Several reasons result in teeth staining, either intrinsic or extrinsic staining. Teeth staining also has several other types other than these two above mentioned types.

1. Intrinsic staining

It occurs below the teeth surface that is the hard layer known as dentin. Teeth staining agents just penetrate the teeth enamel and result in this type of stain.

Causes

  1. Excessive fluoride use

  2. Medication side effects – such as, tetracyclines are the antibiotics that are associated with teeth discoloration especially in younger children.

  3. Antipsychotics, medication to treat hypertension, chemotherapeutic agents are also associated with both intrinsic and extrinsic staining.

  4. Trauma to oral cavity – bleeding and teeth root damage

  5. Aging – that results in natural teeth discoloration

:diamond_shape_with_a_dot_inside: Intrinsic teeth staining sometimes doesn’t get treated with bleaching and requires porcelain veneers.

:diamond_shape_with_a_dot_inside: It sometimes requires the dental implants to replace the damaged teeth roots.

2. Extrinsic staining

In this type of staining, the stain doesn’t penetrate the dentine and just remains on the outer surface of teeth known as enamel.

Causes

  1. Consumption of caffeine-containing beverages – coffee, wine, cola drinks

  2. Aging – that results in damage of enamel

  3. Excessive tobacco use – nicotine causes discoloration of enamel

  4. Lack of oral care

It can be removed by teeth whitening procedures in one or two visits to the dentist or by using at-home methods.

:white_check_mark: Summary
Intrinsic and extrinsic teeth staining is caused by several different reasons. Aging, medication, caffeine-containing beverages, and tobacco smoking can be important reasons. Extrinsic stain affects the enamel and intrinsic stain affects the dentin.

2. Teeth whitening procedures

:tooth: There are a lot of teeth whitening procedures to get the low cost, safe, and short-timed whitening of teeth. It can be done by a professional dentist in an in-office procedure and at home by using teeth whitening kits from the medical store.

2.1. Teeth whitening agents

There are several teeth whitening agents either incorporated in the toothpaste or toothpaste tablets. Some of them have been listed below:

:small_orange_diamond: Silica
:small_orange_diamond: Pyrophosphates
:small_orange_diamond: Hydrogen peroxide
:small_orange_diamond: Carbamide peroxide or urea peroxide

Normally, in the in-office procedures by a teeth whitening dentist or at-home by yourself, H2O2 and carbamide peroxide are preferred agents respectively.

:white_check_mark: Hydrogen peroxide – 10-40%

Normally, in an in-office treatment, the bleaching agent is hydrogen peroxide in a 10-40 percent concentration. While hydrogen peroxide in high concentration is not recommended to use at home.

:white_check_mark: Carbamide peroxide

  1. For at-home teeth whitening, your dentist may recommend you a teeth whitening kit that contains carbamide peroxide as the bleaching agent.

  2. Carbamide peroxide is relatively milder than H2O2, so there are fewer chances that your gums or oral cavity will be affected.

  3. Carbamide peroxide breaks down in hydrogen peroxide and performs the same action.

2.2. Steps of in-office teeth whitening

Teeth whitening procedure – more precisely known as chairside bleaching gets completed in a maximum of one hour at the dental clinic. There are the following steps that a teeth whitening dentist may perform to complete the treatment:

1. Preparing for the treatment

  1. First of all, when you reach the dentist’s office and take the seat in relax mode, a lip retractor is inserted in your mouth.

  2. It helps to keep your lip apart to avoid any discomfort during the treatment.

2. Gingival protection

  1. Second most important step in teeth whitening treatment is covering the gums properly. This process is known as Gingival protection.

  2. Gum protecting gel or sometimes a rubber sheath is applied by a cotton tip stick over the gums.

  3. Covering gel is hardened after the application by using the high voltage light to avoid any adverse reactions. Sometimes teeth are also protected by the application of sensitivity reducing compounds.

:no_entry: Precaution

Cover the gums properly as bleaching agents may cause redness, irritation, and inflammation. Sometimes it may result in bleeding from the gums.

3. Application of bleaching agent

  1. Next step that your teeth whitening dentist will do is the application of bleaching or teeth whitening agent all over the teeth.

  2. Its H2O2 in mild to moderate concentrations – ranging from 10 to 40 % - that is used as a whitening agent.

  3. Carbamide peroxide is used in milder quantities These agents penetrate the hard tissues of teeth to remove the intrinsic and extrinsic staining.

4. How do whitening agents work?

  1. Hydrogen peroxide or carbamide peroxide breaks the teeth stains into smaller pieces by the oxidation reactions that results in the lightening of teeth color.

  2. Teeth whitening gel containing H2O2 or carbamide peroxide is then rinsed off and a fresh coat is applied. The same procedure is repeated until the desired results are obtained.

  3. This process may last from half to full hour depending upon the stains that are needed to be removed.

  4. Teeth whitening procedure does not give you lifetime whitening. You will need the follow up just like the case of Botox lips or lip flip that requires touch-ups for maintained results.

5. Keep in mind

  1. While doing the teeth whitening procedure at home, properly cover the gums to avoid any reaction.

  2. If the bleaching agent starts irritating the gums, instantly stop the procedure and rinse the mouth.

  3. Don’t go for this procedure if you have large fillings and caps in your teeth as it may give your teeth the different colors – as it will not bleach the fillings and caps.

  4. Don’t wait for your teeth’ color to turn brown, as the bleaching procedure doesn’t work well for brown teeth.

  5. Teeth discoloration that results as a side effect of tetracycline – an antibiotic – may not be treated by teeth whitening procedure.

  6. Overusing the teeth whiteners may result in damage to tooth enamel.
