Why do teeth change color?

Numerous medications, dental trauma (fractures, impacts, etc.), and the removal of the tooth nerve are just a few of the reasons of tooth discoloration.

Teeth discoloration in babies is influenced by the mother’s or the baby’s use of antibiotics like tetracycline during pregnancy; in some instances, special foods or drinks like Coca-Cola, coffee, and foods with coloring in the ingredients also have an impact.

Your teeth’s alterations in color may indicate the reason.
 

– Yellow: Your teeth’s white enamel exterior may deteriorate as you get older. Your teeth’s golden interior can now be seen more clearly.

– Brown: Teeth may change brown as a result of tobacco use, dark beverages like tea or coffee, and careless brushing techniques that promote tooth decay.

– White: Too much fluoride can create white spots on developing teeth. Fluorosis is a condition that develops when molars are exposed to excessive amounts of fluoride through toothpaste, rinses, or drinking water.

– Black: Your teeth may become gray or black due to dental decay or necrosis of the tooth pulp. Black teeth can also result from chewing betel nuts. Your teeth may develop a dark line if you are exposed to minerals like iron, manganese, or silver in the workplace or from any supplements.

– Purple: Red wine has the potential to change the hue of your teeth’s enamel.

How does bleaching work?

Hydrogen peroxide and carbamide peroxide are the whitening agents. (hydrogen peroxide). These two substances have the capacity (qualitative property) to easily penetrate the enamel and dentin layers of the tooth and spread to every area of the tooth. These peroxides—carbamide and hydrogen—are converted into oxygen radicals, which penetrate between the enamel prisms (the tooth’s outer layer) and disperse (threaten to disappear) the colored molecules that determine the tooth’s color.

Only the inner color of the teeth changes during whitening, leaving the tooth’s structure unaffected.

Inside the tooth, bleaching agents disintegrate into smaller molecules and travel in all directions. Even if the entire molar is not bleached, the whole thing becomes whiter.

The efficacy of peroxides in teeth whitening has been established by numerous scientific studies.

Bleaching chemicals do not harm or impact the enamel and dentin (the two layers of a tooth), porcelain, or existing fillings.

Does whitening affect the connection between the filling and the tooth?

Although teeth-whitening products inject a lot of air into the teeth, the bonds that hold in place pre-existing fillings are unaffected.

But since the high levels of oxygen in the teeth have a negative impact on the filling of the tooth, white fillings produced after bleaching should be delayed for a time of 7 to 10 days. (for new fillings to be made).

How long does the bleaching effect last?

The whitening outcomes are reliable. However, you might need to repeat the bleaching every two years based on your eating habits and lifestyle.

Regular use of the whitening paste advised by the doctor is advised to preserve the whitening impact.

 

Does bleaching cause hypersensitivity?

Bleaching can temporarily cause hypersensitivity. At the conclusion of the bleaching session, it will cease. The hypersensitivity in recent tooth bleaching products has been eliminated by the addition of ingredients like potassium nitrate.

Research has shown that potassium nitrate acts as a tranquilizer by penetrating the pulp tissue, dentine, and even enamel. (analgesic and anesthetic effect).

Fluorides are an ingredient in teeth whitening products and are used to treat tooth hypersensitivity and avoid cavities.

 

Does the tooth whitening cause problems weakening the tooth enamel (the outer layer)?

According to scientific studies supported by the “American Association of Dental Research,” bleaching products containing fluorides and potassium nitrate lessen tooth sensitivity, promote dental health, slow down tooth decay, and increase enamel abrasion resistance.

Only a dentist should conduct teeth whitening procedures. During the time when a woman is nursing or pregnant, the operation is not permitted.

When done correctly and with the right materials, teeth whitening is now both safe and efficient.  This includes a thorough initial diagnosis, expert teeth cleaning of stones and existing stains, an explanation of the teeth whitening procedure, and monitoring throughout the bleaching process.

How many ways are there for bleaching?

The following methods of bleaching exist:

1. Office bleaching; done in a dentist office, takes about 30 minutes, and can be done in various sessions depending on the patient’s preference for a particular tooth shade. (35–38% hydrogen peroxide) is a significant portion of the product’s active component for bleaching.

2. At-Home whitening: The mouth is measured, silicone cases are made, and the cases are placed in the mouth during the day or night while being filled with whitening agents. Depending on the proportion of the active ingredient that causes the whitening (10%-15%-20%-22% Carbamide Peroxide), the holding period can range from 45 minutes to the entire night.

3. Non-vital bleaching: Bleaching performed on teeth whose colors have altered after nerve removal. In these situations, the tooth filling is taken out and the bleaching substance is put in the cavity and allowed to sit there for three to five days. A temporary filling is placed for 10 to 15 days while waiting for the oxygen level to drop before the final filling can be completed, and this process is repeated until the desired bleaching result is achieved.
