Making prosthetic porcelain teeth is no longer a strange thing today, this is a technique that uses porcelain teeth to cover the outside of the teeth, helping to bring white and even teeth to the performer. However, to keep the teeth beautiful, bright and durable is something not everyone understands. The following article will point out the factors that affect the durability and beauty of porcelain teeth, thereby helping you know the best way to take care of them.

1. Factors affecting the durability and beauty of prosthetic porcelain teeth

In addition to factors that affect the durability and beauty of teeth such as the position of the teeth covered with porcelain, the skill level of the doctor or the equipment, the quality of the porcelain, the care after the porcelain coating... The quality of porcelain and the health of the pulp are two factors that directly affect and determine the durability and aesthetics of porcelain teeth.
Durable porcelain teeth no longer depend on 2 components, which are the outer porcelain teeth and the inner real teeth. If the porcelain tooth part is broken but the real tooth is still good, the dentist only needs to replace another layer of porcelain teeth. However, if the real tooth is broken and inflamed enough to have to be extracted, then the porcelain crown will also have to be removed with the real tooth.

2. Factors related to the tooth pulp

Dental pulp Teeth that are kept with pulp can remain healthy and last for a long time. They have the ability to help teeth repair themselves, fighting harmful bacteria that multiply in the oral cavity.
Teeth are kept pulp, when making porcelain teeth also become natural, beautiful color, achieve high aesthetic effect. At the same time, real teeth with preserved pulp will also be durable, less likely to change color after a period of use.
So in the process of grinding teeth, the doctor's skill is very important to avoid causing harmful effects to the tooth pulp. Dental pulp is very sensitive to high temperatures, so it is necessary to spray water strongly enough, in the right direction, to reduce friction when grinding.
The more real teeth are grinded, the greater the risk of damage. In order to install porcelain teeth, real teeth need to be sharpened and shaped to be able to fit porcelain teeth evenly, often called pulps.
Real teeth only grind at "enough" and "reasonable" levels, do not grind too much or too little so that when attaching porcelain teeth, they will fit closely together without harming real teeth. Teeth made of porcelain also need to have a certain thickness, enough to bear the impact on the teeth such as during eating and chewing, and have a color suitable for aesthetic results.
If you grind your teeth too much, it will damage, risk affecting the tooth pulp, causing tooth sensitivity when eating and chewing.
If you grind your teeth too little, the teeth will not be able to fit closely to the real teeth, if the porcelain layer is too thin, it will lead to easy breakage, difficult to achieve aesthetic results in color. But if the porcelain layer is too thick, it will make the teeth big, rough, unnatural and difficult to clean. Therefore, the qualification of the doctor performing the restoration of porcelain teeth is very important.
Axis of teeth when eating, chewing must be on the same axis with the direction of the real tooth root The chewing force of porcelain teeth must be coaxial with the real tooth root to increase the bearing capacity and absorb the best force.
If the shaft is installed in a different direction from the axis of the tooth root, during eating, chewing, the tooth root is damaged quickly, after a while, dental diseases such as gingivitis, bone loss or broken tooth root will appear. real.
The initial manifestation is that the eating and chewing force of the teeth is significantly reduced after installing porcelain teeth. Therefore, do not make porcelain teeth to adjust the tooth axis such as correcting crooked or crowded teeth. In such cases, braces - orthodontic treatment is needed.

3. Factors related to external prosthetic porcelain teeth

Porcelain coating is too hard When the outer layer of porcelain is too hard, it will inadvertently cause abrasion of the opposite real tooth, damaging the real tooth. Not only that, too hard porcelain teeth will reduce the feeling of chewing food or cause discomfort when eating strongly.
Porcelain layer is too thin or too thick If porcelain teeth are too thick, it will make food easy to stuff under the teeth, very difficult to clean, which can easily form plaque, tartar, and bacteria that cause growth. bad breath and prone to dental diseases.
If this situation lasts for a long time, food and plaque stick to the gap between the real teeth and the porcelain teeth more and more, the risk can damage both teeth.
The size of porcelain teeth is not suitable for real teeth When the roots of the teeth are under excessive pressure compared to the ability to design porcelain teeth that are not suitable, real teeth will quickly become weak, shaken and then fall out, unable to be kept. The bridge is also susceptible to excessive impact when the patient has strong eating or chewing force.
Therefore, it is necessary to choose a porcelain tooth with moderate hardness, designed to match real teeth to create a natural chewing feeling, commensurate with the surrounding teeth in the mouth. Porcelain teeth when wrapped around real teeth need to have a suitable thickness, close to the real teeth that have been ground.
Real teeth are subjected to excessive force due to incorrect specifications. Real teeth will be overloaded if the design of porcelain teeth is not suitable. Real teeth will quickly become weak, wobbly and eventually fall out.
The reason is that the large missing tooth space will make the force acting on the bridge span (the part of the missing tooth) greater, the faster the abutment teeth (real teeth that have been ground to make a bridge abutment) will quickly become overloaded and wobbly. Therefore, when designing, the doctor needs to make a reasonable calculation of the "ability" of the abutment to be able to support those missing teeth.

4. How many years can porcelain teeth be used?

Currently, there are 2 popular types of porcelain teeth that are chosen by many people:
Metal porcelain teeth Metal porcelain teeth are porcelain teeth with metal outer edges that are not durable. Normally, metal porcelain teeth only maintain aesthetic results for a few years, because after this period of time, the metal will be acidified in the oral cavity, causing blackening of the roots of the teeth, reducing the properties of the teeth. Beauty.
Full porcelain teeth Full porcelain teeth are porcelain teeth that do not use metal but use high-quality porcelain materials. All-porcelain teeth have the advantage of natural whiteness and shine, just like real teeth, but they are more durable and harder than real teeth, are not eroded and acidified in the oral cavity like metal porcelain teeth. If all-ceramic crowns can maintain durability and stable aesthetic results, at least 15-20 years (depending on the condition of each person's teeth).

5. Attention to oral care after porcelain crowns

For healthy teeth, maintaining beautiful, shiny teeth, proper oral care is very important. Therefore, after covering porcelain teeth, you need to pay attention:
Should eat thin porridge after porcelain crowns because at this time the teeth are still very weak and vulnerable, eat porridge to recover quickly. Avoid eating or chewing hard, chewy foods. Avoid strong impacts on the porcelain crown area. Clean teeth gently, carefully to maintain the whiteness of porcelain teeth. In short, porcelain crown is a cosmetic dental restoration method for tooth defects that cannot be overcome by conventional methods. This is a dental measure that acts directly on the teeth, changing the appearance and supporting the function of the teeth effectively.
