When you see this picture, you must think that this is a 70 or 80 year old man, however you are wrong, he has just turned forty-six years old and his youthful contempt for his teeth has put him prematurely in the difficult position he is in today. Most people do not know that the alveolar bone has the property that when a tooth is missing, it continues to resorb. When a tooth is diseased, it takes several visits to the hospital to be cured. Many people refuse to make several trips to the hospital when their teeth are in pain and do not want to spend time, so they just pull them out. When all the teeth are missing, we have to make a full denture, which completely relies on the denture bed to cover the alveolar ridge to get fixed, so the height of the alveolar ridge determines whether the full denture can be worn firmly and can be used. When you remove your teeth prematurely, after ten or even twenty years, with the continuous resorption of the alveolar bone, the alveolar ridge becomes low and flat, just like this one in our picture, which makes the restoration of the full denture extremely difficult and makes you unable to eat, which directly affects your quality of life and even affects your whole body health. I hope each of us can take care of our teeth, treat each tooth seriously, go to the hospital in time for treatment of dental diseases, and do not pull teeth easily.
