Five-year-old children with toothache may have pulpitis in their milk teeth, which may develop into tooth decay if they do not maintain proper hygiene. If the caries is not filled in time, it will turn into pulpitis, which leads to facial redness and swelling as well as pain and afraid to bite, and this is the time when you need to visit a pediatric dentist at the first time. Because the age of five is too young, it is not suitable for children in general if you go to adult dentist. The endodontic treatment is not the same as for adults. The nerve is treated by means of an endodontic needle, after which the infected material can be flushed out by rinsing, and finally the root canal is filled with calcium hydroxide and waited until the milk tooth recedes. It is not possible to use adult dental cement because it is non-resorbable and can be an obstacle for later tooth replacement.
