“Can you have teeth whitening for porcelain crowns?” This is a question that many customers are concerned about before intending to have cosmetic dentistry. Let’s refer to the article below to understand this topic better.


Porcelain crown is a method of replacing the old enamel layer with an artificial enamel layer. This method is performed by covering the entire tooth surface with porcelain crowns to ensure the functionality of the crown and give the tooth a new shape and a brighter white color. Porcelain teeth are in fact false teeth, used for replacing teeth that have been lost or malfunctioned or are not in good shape.

Customers can have a porcelain crown procedure in cases:

– Due to decayed or cracked teeth, broken, causing an uncomfortable feeling, reduced chewing function, and loss of aesthetic.

– Weakened teeth due to severe tooth decay.

– Due to enamel erosion or discoloration.

– When the teeth are not in good shape

At that time, customers will need to have porcelain crowns to improve their teeth.

First to ensure the integrity of the teeth and to ensure the chewing and eating function and the aesthetic factor. In modern days, porcelain crown in aesthetics is a dental method of restoring the teeth chosen by many customers for different reasons.

The prerequisite factors before having porcelain crowns are that the dentist will grind the teeth about 1-1.5mm/surface, thereby creating a gap for the crowns to cover the real teeth. The process of grinding real teeth possesses the risk of causing problems in the postoperative period: Long-term sensitivity affects the chewing function, the tooth pulp is affected leading to inflammation or pulp necrosis, and infected root, that requires root canal treatment. Therefore, from the perspective of professional and dedicated dentists, we advise that customers should consider it very carefully before having porcelain crowns for aesthetics.

Can You Have Teeth Whitening For Porcelain Crowns?


“Can you have teeth whitening after having porcelain crowns?” This is one of the most concerning questions of customers.

Because restoring real teeth with a porcelain tooth is a method of using porcelain crowns to cover the crowns of real teeth to support chewing function and aesthetic factors.

In some cases, after a period of time using porcelain teeth will lead to discoloration and yellowing, affecting the aesthetics of teeth and daily communication.

Teeth whitening is a method of using specialized bleach to work through a redox reaction, from which the molecules in the bleach will disrupt the protein chains in the plaque on the teeth, making the teeth whiter.

However, teeth whitening products only affect real tooth enamel, but cannot react much with porcelain, Composite, or other similar dental materials. So teeth whitening for porcelain teeth is very difficult it is only effective in some cases.


Teeth whitening is a method of improving discolored or stained teeth, ensuring the health of the teeth without harming the enamel or altering the structure of teeth if the procedure is carried out properly. It is recommended to have teeth whitening at a reputable dental center because reputable dental centers have genuine teeth whitening products, modern machines, and advanced teeth whitening technology.

If we whiten our teeth at home, we also need the appointment and supervision of the dentist, avoiding the use of bleach of unknown origin and concentration. If teeth whitening is not done properly, causing the bleach spreads out of the whitening tray, it can cause burns to the gums and risks of serious oral diseases.

Teeth whitening for porcelain will give different results depending on the causes of tooth discoloration and the condition of the teeth.

In these following cases: pregnant women, people allergic to one of the ingredients of the whitening products. They must take care of their teeth carefully during the recovery period.


1. Teeth whitening at dental centers

The dentist will use whitening bleach at the right concentration level normally from 35 – 37%, and adjust the light with strong intensity to activate the whitening bleach. When using bleach, customers will have anti-sensitivity products and wear a specialized tool to protect their lips, gums, and oral cavity.

2. Teeth whitening at home

Customers can also have teeth whitening for porcelain crowns at home in the following way: the doctor will take an impression of the teeth, and clean the whitening tray to fit the size of the customer’s teeth. This is to prevent saliva from entering the teeth as that will interfere with the whitening process.

The doctor will provide whitening bleach with a concentration level of 10-15%, then instructs the customer on how to use the whitening tray as well as how to handle possible problems.

Self-service at home helps customers be more active when needed. Customers only need to remember that the minimum time of teeth whitening required is 2 to 3 hours/day. In terms of cost, at-home teeth whitening is less expensive than in-clinic service. Teeth whitening at home is not optimal for all cases and is only suitable for mildly stained teeth.

When performing teeth whitening, customers should remember the following issues:

-If teeth are stained, it is necessary to apply both teeth whining at the clinic and wearing a tray at home to ensure the best result.

-Customers must remember to abstain from colored foods and beverages, avoid eating foods that are too hot or too cold, and take care of your teeth as carefully as possible to limit the risks of teeth re-discoloration.

Customers should not buy teeth whitening products yourself, because it can possibly cause burning gums and inflammation of the pulp.

Customers should choose a reputable – reliable – safe dental center to have advice from professional dentists to ensure the best results and their safety.
