After orthodontics, the gums and roots will be damaged in a short time, because the teeth are equivalent to being forcibly replaced, and the teeth are no longer as tight as before orthodontics. Try to avoid eating hard things. Eating hard food will lead to secondary damage to the root and lead to orthodontic failure.
In addition, as the saying goes, toothache is not a disease, but it really hurts, because there are a lot of neurons in the root of the tooth, and the pain in the tooth is very obvious. Eating hard food is easy to cause toothache, because the root is unstable. These are the reasons why doctors told not to eat hard things after orthodontics.
The most serious thing is that because all the people who have undergone orthodontic surgery are adults, their teeth are fixed and they eat hard things. When the teeth have not recovered, it is easy for hard objects to fall off, causing irreversible damage to the gums. Once this happens, it will not be solved by orthodontics alone, but by filling and planting teeth.
So it is reasonable for the doctor to tell you not to eat hard things after orthodontics. In addition, since the teeth have not recovered, we should also avoid eating soft and glutinous things to prevent the teeth from falling off. At the same time, because the teeth are wearing braces, it is also necessary to ensure the cleanliness of the teeth, so that the teeth can recover faster and you can eat anything after recovery.
