What causes porcelain crowns to fail?

Cosmetic porcelain teeth are no longer a strange method to many people, with outstanding advantages that help overcome dental defects quickly, without taking much time, making many customers prioritize choosing this method.

However, at Thuy Anh Dental Clinic, we have received many cases of customers complaining that they had their porcelain teeth done at another facility, and after a while, they experienced gingivitis, bad breath, tooth sensitivity, etc. So what is the cause of defective or damaged porcelain crowns? And to choose a reputable dental clinic that does good cosmetic porcelain teeth, what criteria should be based on?

Causes of defective and damaged porcelain crowns

Faulty or damaged porcelain crowns cause many harmful effects and serious consequences such as: gingivitis, receding gums, exposing the lower border, grinding too much real tooth tissue leading to pulp death, tooth wear due to misaligned porcelain crowns, inability to chew due to toothache, toothache, etc.

There are many reasons for faulty or damaged porcelain crowns. Of these, 30% is due to the quality of the porcelain, the type of porcelain; 40% is due to the doctor's technique, and the remaining 30% is due to the patient's oral care and hygiene. Let's find out more about the common causes below:

1. The doctor's tooth grinding and root canal treatment techniques are not good.

The nature of grinding the tooth stump is to create a pillar to fix the porcelain crown above by filling the gap inside and firmly attaching it to the porcelain crown. The technique of grinding the tooth stump is quite complicated, affecting all 5 surfaces of the tooth, which means that the enamel will be worn away. If not done correctly, the real tooth tissue will be ground too much and the doctor will treat the pulp indiscriminately, causing the tooth structure to be destroyed. Poor pulp treatment can cause inflammation and pain after treatment.

2. Inaccurate porcelain tooth fabrication

The porcelain tooth fabrication process is not performed accurately, leading to the porcelain crown not fitting tightly to the real tooth, the finished line is rough, not smooth, creating gaps, which are a place for bacteria to reside, causing gingivitis and periodontitis.

The finishing line of the tooth must not violate the biological space (the soft tissue attached to the tooth root on the alveolar bone). The biological space acts as a barrier to prevent bacteria from entering the important periodontal components below such as the alveolar bone, periodontal ligament, and cementum.

Therefore, clinically, common manifestations of bio-space invasion are gingival recession, periodontal pockets or persistent gingivitis despite good daily oral hygiene.

3. Due to poor quality of porcelain and adhesive

Poor quality porcelain teeth often do not have a guaranteed origin, are easily broken or chipped during chewing, and have low elasticity.

In addition, porcelain teeth are fixed to real teeth by a specialized glue. If the glue quality is not good, it can cause allergies to the contacting teeth, and the porcelain teeth can become loose or damaged.

4. Not completely treating oral diseases when making porcelain teeth

Weak, sensitive teeth or incomplete treatment of gingivitis or periodontitis before getting porcelain teeth also increases the risk of infection many times over.

5. Improper oral hygiene

Porcelain teeth also need good care and protection like real teeth. If not properly cared for, they can lead to a high risk of gingivitis, bad breath, tooth decay, etc.
