Do metal ceramic teeth really blacken the gum line?

The reason why metal ceramic teeth cause black gum lines is because the structure of the inner rib is made of metal, when exposed to the acidic environment in the oral cavity, it causes cross-oxidation between the metal and acid compounds.
In addition, there is also an indirect cause of the above condition when you brush your teeth incorrectly, causing food particles to accumulate on the body of the tooth, gradually oxidizing and forming acid with the ceramic teeth.
In addition, brushing your teeth incorrectly can also cause gum wear, not rubbing against the ceramic teeth, causing the ceramic part on the body of the tooth to gradually erode, revealing the metal frame on the ceramic teeth and the black color at the gum line.
In dentistry, for conventional metal porcelain teeth and titanium porcelain teeth, after a period of use, the gum line will turn black, the metal frame on the porcelain teeth will be oxidized due to the acidity of the oral environment.
As for porcelain teeth made from precious metals, the gum line may or may not turn black depending on how you clean your teeth and mouth.

Are metal porcelain teeth durable?
Whether metal porcelain teeth can be used for a long time or not will depend on many different factors such as: the dental clinic where you choose to do it, the type of porcelain used on your teeth and your oral health, etc.
In fact, the time you can use metal porcelain teeth lasts up to 20 years. But there are also a few cases that cause serious consequences right after applying metal porcelain. The cause may also be thin porcelain material, poor medical qualifications, improper oral care. ..
Therefore, the time of using porcelain teeth will not have an exact number. In cases of broken or damaged porcelain teeth, you should immediately go to a dental facility to have the medical team check and replace them (if possible).

Comparing metal ceramic teeth and all-ceramic teeth

Aesthetics
Metal ceramic teeth: the color is not the same as real tooth enamel. When the stage light is on, the metal color will be reflected to the outside, so the teeth will usually be dark.
Therefore, metal ceramic teeth are often chosen by people working in the field of aesthetics or professions that are often exposed to stage lights.
Porcelain crowns: because they are made of ceramic, their color will be more similar to real teeth.
Risk of black gum line
This is also the distinction between these two types of teeth. In metal ceramic teeth, the metal has the property of being easily oxidized in the acidic environment of the oral cavity, so after a period of use, the metal frame inside the ceramic teeth will become increasingly darker, not only causing loss of aesthetics but also threatening the health of the patient if the user has a history of metal allergies.
Meanwhile, porcelain-covered teeth do not have the above condition and the surface of the porcelain teeth is always maintained as bright and beautiful as the beginning.
Durability
Metal-ceramic teeth are made with a metal frame on the inside that can withstand quite high chewing force and the force acting on the enamel layer is also higher.
Meanwhile, for metal-ceramic teeth, during the manufacturing process, they will be baked at a temperature > 1600 degrees Celsius, so the hardness is 4 times higher than metal teeth, and the durability is also higher than traditional teeth.
Lifespan
When used for 3-5 years, metal-ceramic teeth will gradually appear as the metal frame is exposed and blackened around the gum line, so many customers do not choose to make metal-ceramic teeth because the aesthetics of the teeth are not high.
All-ceramic teeth can last for over 20 years, and there is no blackening of the gum line like metal-ceramic teeth, so you can rest assured to use them.
