The initial degree of caries: the hard surface of the tooth is affected - often the patient has no complaints, but if treatment is not started in a timely manner, this can lead to the serious tooth damage. In order to detect and prevent the development of caries in time, it is necessary to visit the dentist regularly.
Medium degree of caries: tooth enamel is destroyed - the patient experiences severe pain and sensitivity to hot, cold, sweet or salty foods.
Deep degree of caries: infection reaches the dental nerve - if the tooth is not treated in a timely manner, caries penetrates into the layer of the jawbone under the hard tooth root (complicated caries). It is at this stage that acute pain can sease, and caries becomes chronic. In such a situation, it is necessary to carry out endodontics (cleaning the tooth canal).
