What are the hazards of porcelain teeth?

Porcelain teeth are a type of dental beauty that many people want to have. Many celebrities have also had porcelain teeth done to look good on camera. Porcelain teeth are one of the methods of tooth restoration, and generally there is no big problem if it is done in a regular dental hospital.

1. Gingival staining

The problem of black lines (gingival staining) on ​​the neck edge of porcelain restorations makes the gums turn black. This is a common complication of using non-precious metals (nickel-chromium alloy, cobalt-chromium alloy, pure titanium) to make porcelain teeth, and it is very difficult to deal with. In the early days, a high proportion of non-precious metals were selected, which caused a relatively high proportion of gingival staining. The reason is that oxidation occurs between the metal base crown and the gums. Such porcelain teeth must be removed and redone, otherwise it will cause gingivitis over time, gradually develop into periodontitis, and cause loose teeth and loss.

2. Caries of real teeth

Poor grinding of teeth, poor tooth modeling, and inadequate processing technology in the factory all lead to the fact that your porcelain teeth and real teeth do not fit tightly (the gap between the crown and the root is large). After one or two years of use, they become a warehouse for bacteria! Brushing teeth, using mouthwash, and using dental floss are all useless. The bacteria hidden between the porcelain teeth and real teeth enter the braces and gradually corrode the real teeth, causing caries of the real teeth. Over time, the real teeth may even rot completely. Watching your real teeth being corroded in the porcelain teeth, your own teeth will eventually become the companions of the porcelain teeth.

3. Porcelain Collapse

Some patients still use their porcelain teeth even though they have broken. Not only is it unsightly, but the metal will rub against the food in the mouth for a long time, and chemical reactions will occur under the action of saliva. It is not known whether it is harmful, so it is recommended to remove it as soon as possible.

4. Pain caused by hot and cold stimulation

I have a porcelain tooth, but I dare not eat too much hot, cold, sour or sweet food, and it hurts from time to time. This is mostly because the dentist grinds the teeth too quickly during the preparation process, causing excessive stimulation to the pulp, and the pulp is still in a state of congestion. Before making porcelain teeth, you must evaluate the condition of the periodontal gums. If there is obvious gingival inflammation, redness, swelling, atrophy, abnormal color, etc., periodontal treatment is required first, and the porcelain tooth restoration can be performed after the gums return to normal. But some doctors can't wait and do it right away. As a result, it has to be removed after it is painful. Many people feel good after having porcelain teeth, and they ignore it for several years. Experts suggest that 8 to 10 years after having porcelain teeth, even if there are no discomfort symptoms, you should see a dentist for a follow-up check, and it is best to open the porcelain crown for preventive treatment.

Porcelain teeth are a type of restoration method that mainly treats tooth defects and tooth loss. They are generally divided into metal porcelain teeth and non-metal porcelain teeth. Generally, porcelain teeth are harmless, but if they are not made properly, some symptoms will occur.

1. If there is an overhang on the edge of the porcelain tooth, bacteria will easily accumulate at the overhang, which will cause gingivitis and periodontitis.

2. If the porcelain teeth and the abutment teeth are not tightly fitted and there is a gap, it will cause caries of the abutment teeth. Moreover, this kind of caries is not easy to be found, which will cause the caries of the abutment teeth to become more and more serious.

3. After a long time, the edge of the gums will be black. For patients who undergo head MRI, metal porcelain teeth will have artifacts, and the porcelain teeth need to be removed before the MRI examination.

4. If the teeth are not properly prepared and do not meet the requirements, there is a chance that the porcelain teeth will fall off. If the patient's bite is severe and the bite force is strong, the porcelain teeth will also cause porcelain to break. Porcelain tooth restoration is a method of treating dental diseases, so it is generally harmless. If the teeth are damaged to a certain extent, it is recommended that you can have porcelain teeth to repair them and restore the shape and chewing function of the teeth.

In view of the fact that many patients have certain doubts about porcelain teeth, the doctors of Suzhou Stomatology Department have specially introduced some common knowledge about porcelain teeth to help everyone understand porcelain teeth correctly and scientifically, and avoid unnecessary pain due to momentary wrong choices.

1. Ordinary porcelain teeth do contain nickel, but the nickel content in porcelain teeth produced by regular manufacturers meets national standards. All major hospitals in China are using them. A very small amount of nickel plus strict operation and bonding technology will not pose a threat to human health. Most of the nickel released by nickel-chromium teeth will be swallowed into the digestive tract and will not accumulate in the mouth. Moreover, the amount of nickel released from nickel-chromium alloys is significantly lower than the amount of nickel ingested in people's diet. Despite this, a small amount of nickel will still be absorbed by the human body. During a certain period of time when patients wear nickel-chromium teeth, the nickel content in the blood, saliva, and urine will increase, but it is generally within a safe range and will not cause harm to the human body.

Second, it is possible that some illegal institutions or clinics use inferior raw materials with excessive nickel content. Generally, porcelain tooth cooperation units are large porcelain tooth research and production centers in many provinces and cities, with high technical levels and all legal qualifications, and use qualified materials in accordance with national standards. The nickel content is within the national standard value range.

3. The quality of porcelain teeth is also related to the quality of doctors. Professional doctors have higher education in stomatology and legal certificates (qualification certificates and practice certificates). Professional dental hospitals are approved by urban health bureaus and other health administrative departments.

4. There are many varieties of porcelain teeth. If you are concerned about ordinary porcelain teeth, you can choose nickel-free beryllium bioalloy porcelain teeth, precious metal porcelain teeth, or all-ceramic teeth. The doctor further added that the materials involved in general porcelain crown restoration are all dental special materials that have undergone rigorous laboratory and clinical experiments. Under normal circumstances, there is no measurable toxicity to the human body; as long as the patient chooses a regular dental hospital, there is no need to worry about this problem.

Generally speaking, whether porcelain teeth can be corrected can be considered from the following three aspects:

1. Number of Porcelain Teeth

If you only have one or two porcelain teeth, you can consider orthodontic treatment. Because porcelain teeth are different from natural teeth, they cannot bear too much force. If there are too many porcelain teeth in the mouth, they cannot withstand the correction force. If the teeth are too crowded, the doctor will recommend removing the porcelain teeth and then undergoing orthodontic treatment.

2. The location of porcelain teeth

If your porcelain teeth are located at the innermost part, it will not affect the correction of teeth. Because during the correction of teeth, the last big tooth will not be put on the bracket. But if you have porcelain teeth repaired on the front teeth, the impact will be relatively greater, after all, the front teeth are directly subjected to force.

3. Types of Porcelain Teeth

If it is a porcelain tooth with a bridge and a crown, you may need to remove the bridge and the crown before orthodontic treatment; if you only have a single porcelain tooth, you only need to polish the tooth surface and use some good adhesives. Of course, during orthodontic treatment, since the porcelain teeth with crowns cannot be moved individually, it will directly affect the effect of orthodontic treatment; doctors will cut the connected crowns to ensure that each tooth can move freely. This is one way to deal with it. Another way to deal with it is to remove the porcelain bridge and install a single temporary crown. The choice of which plan depends on the specific situation of the patient's teeth, but a new porcelain bridge needs to be made after the correction is completed.
