The porcelain tooth has the harm of black lines, and the real tooth inside the porcelain tooth becom

The metals of porcelain teeth are mainly divided into: gold and titanium; Base metals.

There are very few black lines on the gums, because the metal is relatively stable; Base metals will have black lines.

Depending on the ** and black lines of the teeth you do, it should belong to the base metal, the so-called titanium alloy, and only about 4% titanium is added, basically, there is no substantive meaning. The best people are pure titanium, so there are no black lines.

As for stuck food and bleeding gums, it should be a problem that the teeth are not done well and the edges are not dense.

As for the systemic symptoms you mentioned, it should have nothing to do with your porcelain teeth.

The worst porcelain tooth contains the worst element of nickel and the like, which is the same as the spoon, pressure cooker and other materials we use, and there is no big harm.

As long as it is a metal porcelain tooth for a long time, the gums will be a little discolored, just the difference between light and heavy, and there is a card food that indicates that there is a problem with the teeth, it is recommended to visit the hospital in time and remake it, so as not to cause serious secondary caries, resulting in broken teeth and gums

It is recommended that you do it again. You can add 114033328 her. Mine is very detailed.

With the continuous improvement of everyone's living standards, people's awareness of the health care of their teeth is also constantly improving and attaching importance to it, so dental beauty projects are becoming more and more popular. However, many people find that the real teeth inside the porcelain teeth have turned black after doing porcelain teeth, what is going on? Let's take a look.

1. Physician technology

This phenomenon of blackening of porcelain teeth has nothing to do with the material, but is due to the lack of skill of the physician to cause the edges of the porcelain teeth to be unsuitable. If it is located above the gums or does not fit well with the natural teeth, there is a gap between the porcelain teeth and the natural teeth, and then a series of problems such as the black line of the gums will appear.

2. Porcelain tooth material

Due to the unstable chemical properties of the metal, the porcelain tooth with the base metal crown will continue to release some ions, and people with sensitive constitution are not only prone to allergic reactions, but also prone to adverse reactions such as redness, swelling and bleeding of nucleoid gums. At the same time, a large number of ions are deposited in the hard tissue of the gums or tooth roots, which can also cause the gums to darken.

3. The internal structure of porcelain teeth

The enamel of the natural tooth and the dentin of the inner layer have a certain degree of light transmittance, because the metal layer inside the porcelain tooth is opaque, the light can not reach the neck of the porcelain tooth when it is refracted inside, so the contact between the porcelain tooth and the gum is darker than other parts. This blackening is common to all metal porcelain teeth.

4. The preparation is unqualified

Because the preparation of porcelain teeth is unqualified, porcelain teeth and real teeth are not close enough, including *** porcelain teeth (** chain wild porcelain teeth), no matter what kind of metal is used, there may be black lines on the gums.

The above is the content of the black of the real teeth in the porcelain teeth. In short, although porcelain teeth are very good and play a very good role in our dental restoration, before you choose to do porcelain teeth, you should go to a professional dental hospital or clinic with a high level of production and a high level of doctors to implant porcelain teeth, so as to ensure the quality of the implanted porcelain teeth.

Experts said that the main reason for the occurrence of black lines in porcelain teeth is that doctors and technicians are not in place, and the edges of porcelain teeth are not suitable and there are gaps. In addition, if the porcelain tooth is made of base metal, due to its unstable metal chemical properties, the gums in contact with the porcelain tooth will be blackened, which will affect the appearance.

In addition, because the metal layer is opaque, when the light is refracted inside the porcelain tooth, it cannot reach the neck of the porcelain tooth well, so that the part of the contact between the porcelain tooth and the gum is darker than other parts. Therefore, if the production is not standardized, there may be depressed black lines, gray lines, and black gums.

In order to avoid the occurrence of black lines in porcelain teeth, the material is selected as porcelain teeth or all-ceramic teeth, and doctors and technicians with high technical skills should be selected.

It can be seen that the key to preventing black lines on the edges of porcelain teeth is to find a skilled doctor.

The so-called black edge and gum recession of the porcelain crown are not mainly caused by the material, but by the lack of tightness, resulting in the appearance of decay after the food enters.

The nickel-chrome porcelain crown is actually a gray stain (see image below).

The porcelain is made to fit tightly and is properly maintained. The lifespan is 20-30 years.

It is possible that there will be a black line. Gum recession occurs only if the edges of the braces do not fit. Normally, it does not cause gum recession. Lifespan, if you clean yourself in place, you can use it for a lifetime. But what I see is generally 10 years.

Are those two teeth next to your empty teeth good? If it is a dental implant is the best choice, go to the hospital to take a picture and call the doctor to see, the life of dental implants is generally about 40 years, and there is no impact on the teeth next to it, but this is a bit expensive, a tooth costs about 10,000, and the time is about half a year. In the case of porcelain teeth, it mainly depends on the material and the degree of fit, and the main thing is maintenance.

As for the longevity, no doctor dares to guarantee it, it should be. Hopefully, thank you!

Non-porcelain teeth may cause black lines on the gums, because the metal crown is not stable enough to react with the gums and oxygen. This porcelain tooth** is relatively inexpensive but not recommended.

Porcelain teeth and all-ceramic teeth will not have gum recession and black lines, because the inner crown of the porcelain tooth is ** (86%), the biocompatibility is good, and this porcelain tooth is slightly more expensive.

All-ceramic teeth are the best among porcelain teeth, and the biocompatibility is also very good, but **the highest.

Healthy teeth are best not porcelain teeth, and your own teeth are the most intimate.

If you make up your mind to do it, talk to your doctor and be sure to wear it well.

The service life depends on how much you care about it, and it is generally about ten years.

Hello, a successful porcelain tooth needs to have five factors: the choice of a regular hospital, experienced doctors, professional and reputable processing units, personal choice of materials, and personal habits. The general service life is about 10-20 years, and it is possible to use it for a lifetime with good protection.

It is quite normal that the porcelain metal divides the support line. This is to prevent the porcelain body from stretching the porcelain, supporting the porcelain layer on the lingual side or even in the hidden place. Sometimes the back teeth should be made with an all-metal ring to prevent porcelain stretching.

For the sake of aesthetics, there is no way to add this metal edge to the front teeth. Otherwise, the front teeth should also have this metal edge on the side of the show.

You see, this is the metal edge of the tongue. It's like a hand supporting the porcelain layer.

You can do some *** piles so that there will be no black bars.

The doctor is right, don't worry, my one is also haha.
