Pulling 1 pills hurts for 2 years! Rare double teeth are hard to give up.
The dentist reminds you to see a doctor when you find that your teeth are special in shape and seem to be connected as a whole, or when the number of teeth is more than normal. (Photo/Luo Huiwen) Chen Zhaoan, an attending physician in the Department of Dentistry, Tainan Chimei Hospital, said that the boy's two teeth grew together, which was the result of abnormal development of the adjacent teeth when the teeth erupted. This is a rare tooth variation, which is called "tooth fusion or twin". It may be that the two teeth came together during the growth process, or that 1 tooth was divided into two teeth, which looked worse than the adjacent teeth.
Although the crowns of the boy's two teeth are separated, the roots are connected and there is no fusion in appearance. So it was incomplete when the tooth was extracted four years ago, and there were attached roots. Therefore, the diagnosis after referral is more difficult. In X-ray examination, only the images of overlapping roots can be seen. After re-root canal treatment, the existing multiple roots were found by X-ray images from different angles, and then treated with surgical flap, and then diagnosed as root fusion.
It is worth noting that in the incidence of tooth fusion, deciduous teeth are more common than permanent teeth, and they are more common in the anterior teeth area, and the proportion of men and women is equal. Only a few cases of molars and premolars have been reported, and the incidence of posterior teeth area of permanent teeth is quite low.
Rare fused teeth in posterior tooth area
This is a rare tooth variation. When the crown fusion is not obvious or the crown is extracted, it is difficult to interpret and evaluate it simply by X-ray examination, often because the images overlap, which easily affects the dental treatment plan. Because when the posterior teeth are fused with redundant teeth, it often causes tooth type variation, which leads to crowded dentition, improper arrangement and abnormal occlusion.
After the tooth was pulled out, I saw two roots grow together, which is a rare "twin tooth". (Photo courtesy of Chimei Hospital) Relatively speaking, in the process of tooth growth, the probability of dental caries and periodontal disease increases, and even faces the fate of being pulled out. Because the anatomical structure of root canal changes greatly after fusion, once the affected tooth must receive root canal treatment, the treatment process will become quite difficult.
In addition, if persistent pus appears after root canal therapy, although the pain situation has improved, the course of treatment cannot be interrupted, so we must actively cooperate with the doctor's arrangement. No pain doesn't mean no problem, because the infection has turned chronic and the bone will slowly absorb it for a long time. When it swells up again, the treatment time will be longer and the curative effect will be reduced, which has to be paid attention to.
The dentist reminds you that when you find teeth with special shapes that seem to be connected into a whole, or the number of teeth is more than normal, you must see a doctor. You can use X-ray or dental computed tomography for further examination. If it does not affect the appearance and occlusal function, you can not rush to deal with it, but you must follow up regularly and take good care to avoid tooth decay and periodontal disease.
