Many people get tooth decay because they often eat sweets when they were young or do not pay attention to oral hygiene. Over time, if the cavities are not treated, they will decay little by little until only the tooth roots are left. When going to the hospital to see a dentist, the dentist generally does not recommend that patients have their teeth pulled out, because after the tooth is pulled out, the other teeth will become loose. At this time, the doctor will recommend that the patient retain the tooth roots and get porcelain teeth. So what are porcelain teeth? 1. Why does nickel-iron alloy make gums turn black? Because this type of porcelain tooth material has poor biocompatibility and the nickel element is unstable in the oral environment, it can easily become free and precipitate on the gums over time, causing the gums to turn black directly. Some people may even have allergic reactions. Brother Shao recommends that you keep your eyes open before getting porcelain teeth! 2. Why does even cobalt-chromium alloy make gums turn black? Generally speaking, cobalt-chromium alloy is more commonly used in regular hospitals and is not very expensive. Moreover, cobalt-chromium alloy does not contain the toxic element nickel and usually does not cause the gums to turn black. The reason for the blackening is the doctor's poor technique. The porcelain teeth do not fit tightly against the original teeth, causing the gum margins to not fit tightly either. Food debris enters the porcelain teeth, which can easily cause caries and discoloration. 3. Which porcelain tooth material is better? Brother Shao recommends all-ceramic porcelain teeth, which do not contain metal crowns and are closest to the natural color of teeth. The restoration is more beautiful and there is no need to worry about whether it is toxic or not. Of course, it will not turn black, so the price is higher than the previous two, and the cost is about 4,500. Porcelain teeth must be replaced in time if they turn black! Don't trust advertisements too much. You must go to a regular hospital to get porcelain teeth. No matter how expensive the porcelain teeth materials are, if the dentist's skills are not good enough, problems will still arise after wearing them for a few years. If you are missing teeth, porcelain teeth are a good choice, but if you want teeth whitening, forget it. |
