Can porcelain teeth be whitened?

Teeth whitening is a redox reaction that cuts the protein chains that make teeth whiter. However, bleach only works on real tooth tissue. The nature of porcelain teeth does not have the same dentin enamel structure as real teeth, so the white color on porcelain teeth is not effective.

Porcelain veneers replace the old enamel with artificial enamel, completely covering and performing the function of the crown, giving the teeth a new, brighter, whiter shape. Porcelain teeth are false teeth to replace lost, impaired or poorly shaped teeth.
Cases that need porcelain crowns include:
Cracked, broken teeth that cause discomfort to chewing and loss of aesthetics Teeth weakened by too heavy tooth decay Teeth with peeling enamel surfaces, stained tetra, discolored Teeth that are not in good shape Making dental restorations on implants The first thing to do is to cover the teeth or make a crown, first to ensure the integrity of the teeth, to ensure chewing function, then to the aesthetics. . Currently, grinding teeth to make cosmetic porcelain crowns is one of the cosmetic restoration methods that many people choose for many reasons.
Porcelain crowns require real teeth to be ground about 1-1.5mm on each side to create space for the crown to cover the outside of the real tooth. The grinding of real teeth can cause consequences such as: Long-term tooth sensitivity affecting chewing, irritated tooth pulp organization leading to pulpitis, dead pulp, infection at the top of the tooth root and teeth that need to be treated. marrow. Therefore, grinding healthy teeth to make porcelain teeth purely for aesthetic reasons should be reconsidered.

Teeth whitening is a method to improve the color of teeth when teeth are yellow, dull, bring white teeth and a confident smile. The whitening of the moon is done by using bleach combined with chemical light of the lamp to create a reaction that whitens teeth 1-2 tones compared to the original.
Teeth whitening is a redox reaction to cut off the protein chains that make teeth whiter. The drug used for bleaching has a much stronger peroxide concentration of about 35%, which will be activated by the laser light after only 60 minutes. Because the drug has a high concentration, avoid direct contact with the gums because it will burn the gums. Therefore, the bleaching process needs to be carried out in a dental facility.
Alternatively, teeth whitening can be done at home. At-home teeth whitening will use teeth bleaching and bleaching trays. The drug used has a peroxide concentration of 10%-15%. Your dentist will take an impression of your teeth and press them into a set of plastic erasers. The doctor will then instruct how to apply the medicine to the bleaching tray and need to wear it for 2-3 hours a day. After about 2-3 days, the teeth will gradually whiten. To maintain the color of your teeth for a long time, you should wear the tray for a week so that the color of your teeth is stable.

Bleach only works on real tooth tissue, so bleaching porcelain teeth is not necessary because it is not effective. Teeth whitening is only effective for people whose enamel is not too discolored or only mildly contaminated with antibiotics. In case the enamel is too yellow or heavily contaminated with antibiotics, the results of whitening are not high, even there is no change.
Moreover, porcelain teeth are basically made from pure porcelain block, the essence of porcelain is not to be stained, especially food color. Therefore, if you take good care of your teeth, porcelain teeth will always maintain their original brightness and shine. Therefore, after porcelain crowns, to keep the color and durability of the porcelain crowns for a long time, it is necessary to take scientific oral hygiene measures such as:
Use a soft-bristled toothbrush Brush teeth 2 times / day Gargle with salt water or gargle daily, especially after eating. Use dental floss to clean between teeth. Limit the use of hard, chewy and food containing dyes. Check the condition of porcelain teeth, and dental health every 6 months. In case, porcelain teeth are yellowed and discolored, it may be due to improper oral hygiene measures, leading to tartar and plaque build up. In order to overcome the situation of discolored porcelain teeth, it is necessary to go to a dental office to clean porcelain teeth, scrape off tartar and re-polish the porcelain teeth to be whiter.
In short, whitening porcelain teeth is unnecessary and ineffective, because bleaching only works on real tooth tissue. Moreover, porcelain teeth are pure porcelain blocks, the nature of porcelain is not stained. Therefore, in order for porcelain teeth to be strong and durable, it is necessary to perform scientific oral hygiene, and visit the dentist every 6 months.
