What is wisdom tooth? Wisdom tooth, also known as wisdom tooth, refers to the innermost third molar tooth on alveolar bone in human mouth, and the eighth tooth from the central incisor. Due to different genetic factors, wisdom teeth generally grow between 16 and 35 years old, and are the last teeth in a person's life. Because people in this period are more mature, they are named wisdom teeth.
Suggestions for wisdom teeth Modern medicine generally believes that wisdom teeth are the remnants of human evolution. Because wisdom teeth are long at the end of alveolar bone, the alveolar bone of modern people has deteriorated in length, width and strength to varying degrees due to more and more careful eating, which leads to insufficient space for wisdom teeth to erupt, which often leads to ectopic eruption and impaction when wisdom teeth erupt. In addition, the degradation of wisdom teeth itself will also lead to insufficient eruption and asymmetric eruption.
These eruptive abnormalities, as well as the difficulty of cleaning and prevention, usually manifest as pericoronitis of wisdom teeth, dental caries of wisdom teeth or adjacent teeth, periodontitis, pulpitis and other diseases in clinic, causing severe pain. Therefore, it is suggested that abnormal or asymmetrical wisdom teeth should be extracted as soon as possible.
Do wisdom teeth have to be extracted? Normal wisdom teeth don't need to be pulled out: if wisdom teeth grow normally and are in the positive position, wisdom teeth that can erupt normally don't need to be pulled out if there is no inflammation, pain or caries around the crown of wisdom teeth.
Caries of wisdom teeth: If wisdom teeth are decayed, it is not necessary to remove them except the simple caries with shallow occlusal surface can be repaired. However, if a decayed tooth invades an adjacent tooth or is seriously decayed, the dentist will generally recommend pulling it out to avoid future trouble.
Recurrent pericoronitis: the surface of wisdom teeth is covered with gingival flap, which forms a gap with the crown. Food residue is the easiest to hide in, and it is not easy to clean up, and it is easy to form recurrent pericoronitis of wisdom teeth, which brings unnecessary trouble to people repeatedly. At this time, wisdom teeth can be pulled out.
Impacted wisdom teeth need to be extracted: Impacted wisdom teeth are usually buried in alveolar bone, and often cannot establish a normal occlusal relationship with the opposite jaw teeth. Long-term symptoms such as snapping of temporomandibular joint, mouth opening pain and night grinding can be caused, which has a great impact on people's physical and mental health. Therefore, such wisdom teeth need to be removed in time.
What local pain will appear after wisdom teeth are pulled out? This is normal. It is suggested that analgesic drugs should not be used as much as possible, so as not to affect the recovery effect, and ice can be used to relieve the pain.
Avoid licking and pulling wisdom teeth with your tongue in your daily life. In the recovery stage, we should avoid eating spicy, irritating and hot food. Try to give priority to liquid or light food, and don't eat those hard or sticky foods, so as not to affect the postoperative recovery effect.
In the postoperative recovery stage, you should chew slowly when eating, so as not to hurt the position where wisdom teeth are extracted and lead to bleeding, and at the same time, you should keep the habit of brushing your teeth after meals, which can effectively avoid the occurrence of infection caused by residual residues in your mouth. But remember to avoid touching wisdom teeth when brushing your teeth, because if you touch wisdom teeth, it will cause bleeding and infection and affect wound healing.
What can I eat after wisdom teeth are pulled out? After the wisdom tooth is pulled out, it will take two hours to eat. You need to eat some soft food first, preferably liquid food and semi-liquid food. You can drink some rice porridge and milk, and don't eat too hard and hot food to prevent bleeding and infection caused by blood clots falling off. The soft tissue can heal initially about a week after tooth extraction, and those without obvious symptoms can return to normal diet.
