Join us in this article from Drhealthand Beauty by Dr.Sanaz to examine the important question of whether teeth whitening can harm them. The answers may surprise you.

Let the exploration begin.

There has been a lot of talk about the importance of a beautiful smile and keeping teeth healthy in recent years. Different people choose different methods of teeth whitening to have a more attractive smile.

One of these methods is teeth bleaching, which has become very popular today. The cost of bleaching is less than other methods. This issue has increased its popularity among other treatment methods. However, one thing to consider is whether or not bleaching can damage tooth enamel.

Teeth bleaching is the best method that can be used to whiten teeth. This method is low-cost, efficient, and highly popular compared to other treatment methods. There are many methods of teeth whitening in the dental office. 

The choice of each method depends on the condition of the patient’s teeth and the dentist’s opinion. If your choice is bleaching, you should first see to what extent this method can meet your teeth whitening needs. 

The degree of whiteness of the teeth depends on the individual’s expectations. For example, do we want to use this method only to remove the darkening of the teeth, or is the degree of teeth whitening particularly important for us? Answering these questions can greatly satisfy our expectations for successful results from this treatment method.

What damage and complications can tooth bleaching have?

Bleaching is a completely safe cosmetic procedure performed by expert dentists. If a cosmetic dentist does not do teeth bleaching, it may cause some unwanted effects and complications for the person. Improper use of bleaching agents may cause damage to tooth enamel. This type of damage can be irreversible. 

Today, many products called teeth whitening materials in the market can be purchased even without a dentist’s prescription. Unfortunately, many people are unaware of the side effects of such products. For this reason, it is recommended to consult a specialist dentist for bleaching.

Does bleaching damage tooth enamel?

To answer this question, it should be said that if you do not go to a specialist dentist, there is a possibility of unwanted side effects. Among the most important of these complications, the following can be mentioned:

  • Loss of tooth enamel
  • gum irritation
  • Burning and blisters
  • allergy
  • stomach discomfort

Teeth bleaching is not suitable for everyone. Therefore, it is better to first consult with your dentist to get comprehensive information in this regard. 

There are various reasons that change the color of the teeth. Using different treatment options and methods other than bleaching can be effective in this field.

  If we want to definitively answer the question, does bleaching damage tooth enamel? We must say that our answer is negative. Bleaching itself cannot damage tooth enamel. Teeth bleaching is one of the best methods that can be used to whiten teeth. 

The dentist first places the whitening solution on the front surface of the teeth. Then, this solution penetrates the dentin. In this process, which takes about an hour, the stains on the teeth are completely removed. 

This method only affects the tooth dentin, which will result in the whitening of the tooth color. Of course, it goes without saying that if bleaching is done by non-specialized and inexperienced people, it will lead to unwanted side effects.


Are teeth whitening products on the market dangerous?

Non-experts can prepare bleaches that release up to 6% hydrogen peroxide. According to the standard, the concentration of hydrogen peroxide over 6% and carbamide peroxide over 6% is dangerous, and their use is prohibited by all people except dental professionals.

Teeth whitening products, which are sold in the form of ready-made kits in the market and on social media and websites, promise bright teeth, remove stains, fight plaque, and prevent cavities and decay. There is a possibility that such products are not safe for teeth whitening and may be carcinogenic and cause throat and mouth irritation to a great extent. 

There have been many cases where people have had irreversible treatments for their teeth due to going to non-dental centers and using unauthorized whitening products because these chemicals can be carcinogenic.

Do whitening toothpastes have side effects?

In whitening toothpaste, there are very small abrasive particles that exfoliate the surface of the teeth and thus remove the yellowness and stains of the teeth. The way this toothpaste works is different from bleaching materials. If you use this toothpaste for a long time, the tooth enamel will undoubtedly be damaged.


Is it safe to use activated charcoal for teeth whitening?

Activated charcoal is safe for teeth. However, the abrasive nature of this mineral can damage your tooth enamel.

When using activated charcoal on your teeth, be very careful not to scratch or damage it. Do not choose this method if you have any open wounds, cuts, or abrasions.

Charcoal sticks to dental plaques and stains, especially tannin, and removing them helps whiten teeth. Tannin is a chemical compound found in edible and non-edible plants.

Also, charcoal has antibacterial properties that will help to eliminate bad breath.

However, the biggest drawback of activated charcoal is that no detailed and complete studies have been done on the effect of this substance on the teeth.

Of course, no specific side effects of coal for teeth have been reported yet. However, some dentists believe that activated charcoal can lead to wear and tear of tooth enamel.

This issue is aggravated when charcoal is used with a toothbrush.

Some people who have concerns about activated charcoal for teeth whitening replace it with other products.


Our teeth change color due to the consumption of some foods that leave their own color. These substances can include tea, coffee, soft drinks, etc. 

Also, increasing age and taking antibiotics are factors that cause the yellowing of teeth. Yellow teeth can affect your smile and lower your self-confidence. For this reason, people are looking for a way to whiten their teeth.

Although various medical and home methods have been introduced to whiten teeth, be careful not to overuse these methods Because it can cause damage to your tooth enamel and gums, and it is better to always have this done by a doctor to avoid damage to tooth enamel due to teeth whitening.
