The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age, in a process known as "teething". These teeth are the only ones in the mouth until a person is about 6 years old creating the primary dentition stage.
Tooth loss is normal for deciduous teeth (baby teeth), when they are replaced by a person's adult teeth. Otherwise, losing teeth is undesirable and is the result of injury or disease, such as dental avulsion, tooth decay, and gum disease. The condition of being toothless or missing one or more teeth is called edentulism. Tooth loss has been ...
Erupted teeth that are adjacent to impacted teeth are predisposed to periodontal disease. Since the most difficult tooth surface to be cleaned is the distal surface of the last tooth, in the presence of an impacted tooth there is always gingival inflammation around the second molar that is invariably present.
In these cases, teeth may lose their weakened enamel shortly after eruption and are highly susceptible to dental caries. Affected teeth are highly sensitive to chemical and thermal irritants, and may also be difficult to obtain anesthesia. The causes of MIH are thought to be similar to those of other forms of enamel hypoplasia, but occur ...
Xylitol is a naturally-occurring sweetener that can be synthetically produced in bulk. It is classified as a sugar alcohol. [10] Xylitol inhibits acid production by oral bacteria and promotes remineralization of the teeth. [10] It can be found in various products which include chewing gums and lozenges.
Hysteroscopy has been carried out in hospitals, surgical centers and doctors' offices. It is best carried out when the endometrium is relatively thin, that is after a menstruation. Both diagnostic and simple operative hysteroscopy can be carried out in an office or clinic setting on suitably selected patients. Local anesthesia can be used.
These may be partial (to replace some missing teeth) or complete (where all the natural teeth are missing). [8] Dentures may be removable, or fixed in the mouth by dental implants. Advantages: This is the least expensive option for the replacement of teeth. The least invasive, no surgery needed (usually). Disadvantages:
The bone that surrounds the tooth is continually undergoing physiological remodeling. Over time, the root is gradually replaced by bone, [34] which leads to tooth loss. [33] The results of replanting permanent incisor teeth can be divided into short, medium and long-term survival of the tooth. [33]
