Dentistry is one of the clinical disciplines that is closely related to medicine, but also to the technology of making various devices and placing artificial materials that compensate and/or upgrade lost teeth and surrounding structures. Dentistry is also medically responsible for the treatment of patients with diseases of the oral cavity. The main task of dentistry is healthy teeth and oral cavity, ie their preservation and treatment of damaged teeth. Caries is the most common dental disease, and is caused by the multiplication of bacteria inside the oral cavity due to lack of oral hygiene. If not treated in time, caries penetrates deeper tooth structures and destroys them which leading to tooth decay. The most common symptoms of caries are tooth sensitivity and toothache. If these symptoms occur, it is necessary to perform an examination at the dentist in order to prevent the disease immediately at the beginning and to avoid significant consequences for dental health. If caries is not treated in time, there is a high chance that irreparable damage will occur to the teeth and tooth tissue, which can ultimately result in the loss of one or more teeth.
