Hammasjuuret

Hammasjuuret, also known as dental roots, are the primary structures that anchor teeth to the jawbone. Each tooth typically has one or more roots, depending on its type. The number of roots can vary from one to four, with the molar teeth usually having the most roots. The root structure is crucial for the tooth's stability and function, as it provides the necessary support to withstand the forces exerted during chewing and biting.

The root of a tooth is covered by a layer of cementum, a hard, bone-like tissue that protects the root and helps to attach the tooth to the surrounding bone. The cementum is continuous with the periodontal ligament, a fibrous tissue that connects the tooth to the jawbone. This ligament is essential for transmitting forces from the tooth to the bone, which helps to maintain the tooth's position and stability.

The root of a tooth is also the part that is most susceptible to decay and infection, as it is not covered by enamel like the crown of the tooth. This is why dental professionals often focus on maintaining the health of the roots, including regular cleanings, sealants, and prompt treatment of any cavities or infections.

In cases where a tooth is lost or damaged beyond repair, dental implants can be used to replace the missing root and crown. These implants are typically made of titanium and are surgically placed into the jawbone. Once integrated with the bone, the implant serves as a stable anchor for a new crown, bridge, or denture, restoring the tooth's function and appearance.
