It usually takes about one to two weeks for a child to go from dental checkup to braces. The specific time from checkup to wearing braces is related to the material of braces and the condition of the teeth, if ordinary wire braces are worn, then the time required is shorter, but if imported braces are chosen, then the production time may be relatively longer, and if teeth need to be extracted, then the time required will be longer, generally it takes about one to two weeks from the checkup to the wearing of braces. After wearing braces for the first time, some oral discomfort reactions may occur, such as tooth soreness, mucous membrane damage, ulcers, etc. This is a common situation and can be relieved or eliminated in about three days to a week. If it is a severe pain, it is an abnormal situation, and you should seek medical treatment in time. After wearing braces, you should pay attention to avoid chewing hard objects, avoid chewing sticky food, and do a good job of cleaning every morning and before going to bed. It is recommended that children contact their primary care physician if they experience any discomfort after wearing braces to avoid delays.
