Precautions:
1. When wearing porcelain teeth for the first time, patients will feel slightly uncomfortable, and many people will feel very uncomfortable because they don't adapt. At this time, you should practice slowly and get used to it. So learn to get used to eating with porcelain teeth.
2. To clean your teeth in time, you can floss your teeth and go to the hospital for regular cleaning. You can eat normally in about two weeks.
Don't eat hard food when you just wear porcelain teeth. Many people always like to eat nuts or hard things because they don't pay attention to their diet when they first start making porcelain teeth. Prevent the occurrence of broken porcelain.
4. For diet, it must be noted that after making porcelain teeth, try to avoid eating too dark things, such as coffee and dark drinks, because it will quickly precipitate between the teeth and accumulate tartar. After eating such things, you must also keep the habit of gargling. This will make your teeth white for a long time.
