Wisdom teeth growing horizontally do not necessarily need to be extracted, depending on whether they will cause harm to the surrounding dental tissues, and if they are not injurious, they may not need to be removed. If the wisdom tooth growing horizontally is very low, not connected to the outside world at all, and is located relatively far from the front teeth, and does not cause clinically unexplained pain, it can be considered temporarily retained. This is because such wisdom teeth are more difficult to remove, have a higher risk of extraction, and are prone to lower alveolar nerve damage. If the wisdom tooth growing horizontally causes pericoronitis, or if the root of the front tooth is resorbed and the tooth is decayed due to the wisdom tooth pushing against the front tooth, then it is recommended to remove this wisdom tooth. In case of extraction, it is necessary to go to a regular dental clinic. After wisdom tooth extraction, patients are advised to bite the cotton ball for half an hour and then spit it out, wait for 2 hours for the anesthetic to wear off (usually 2-4 hours) before eating and drinking, and do not brush and rinse your mouth for 24 hours to avoid rinsing out the blood clot in the extraction socket and causing infection in the extraction socket. It is recommended to eat a light diet, try to eat warm, cool, thin and soft liquid food, and avoid eating food that is too hot or too hard.
