If one of the missing teeth is a wisdom tooth, it is possible not to replace it. Because wisdom teeth are located in the last part of the tooth row, there are no new teeth afterwards, and wisdom teeth do not have much chewing function for people nowadays, so the loss of wisdom teeth can be left unfilled, but if it is the loss of other teeth, it is recommended to repair them as soon as possible, because the loss of these teeth without repair may cause a series of problems, including the teeth on both sides of the gap will be tilted to the gap side, the over-emergence of the opposite jaw teeth, which will cause problems throughout the dental row. The loss of a tooth will cause the patient to chew on the lateral side, and will also affect the patient’s facial shape and even the temporomandibular joint. In conclusion, missing teeth need to be restored as early as possible, as failure to do so may have a series of adverse effects.
