Many moms and dads usually don’t pay much attention to their babies’ dental problems, and they only rush to the dentist to get a filling when they occasionally find that their babies cry out for toothache or see long cavities, and they think that it can be done at once, but in fact, the cost will be different depending on the degree of tooth decay. When the level of tooth decay is only on the surface of the tooth, it is called “early decay”, and it can be filled at once under normal circumstances. If it is too deep, it needs to be filled once or twice by “pacifying treatment”. This is what is called “filling” under normal circumstances. The cost is about 80-200 RMB depending on the decay situation, and if special padding and other pulp protection treatment is needed, it will be about 100 RMB more expensive. If the tooth decay is not treated in time, the decay will gradually deteriorate and involve the tooth pulp, at this time, toothache is obviously one of the symptoms, and the gradual development may lead to pulpitis, and the worst case is to involve the root tip and appear periapical inflammation. If unfortunately the tooth has reached this stage, the filling may not be completed in one go as it is usually understood, but root canal treatment is required, and root canal treatment requires a certain period of time to complete depending on the degree. Root canal treatment needs to be done depending on whether it is for anterior teeth, premolar teeth, molar teeth, etc. The cost varies from $300 to $1500, depending on the local medical facility you can consult. The cost of tooth filling also differs according to different hospitals, private clinics are generally higher than public hospitals, first-tier cities are generally higher than third or fourth-tier cities, in short, parents need to pay attention to the situation of their children’s oral cavity in time, do a good job of caries prevention, do not go to the step of tooth filling or even root canal treatment.
