We all know that good posture is important. Our parents reminded us every day and now we remind our children. Yet, many people don’t realize how posture affects their oral health. Yes, oral health!
Do you experience frequent headaches or pain in your lower jaw? Then, check your posture and consult your dentist about temporomandibular (“jaw joint”) disorder (TMD), as recommended by the Academy of General Dentistry (AGD).
So, how is poor posture connected to your jaw joint pain? Improper posture places the spine in a position that causes stress to the jaw joint. When people slouch or hunch over, the lower jaw shifts forward, causing the upper and lower teeth to not fit together properly, and the skull moves back on the spinal column. Go ahead, as a test, try to slouch this one time and you will feel the pressure on your joint. Read More →
Root: The portion of the tooth embedded in the gum.
Pulp: Located in the center of the tooth, it contains the arteries, veins, nerves and lymphatic tissue.
Blood vessels: They carry nutrients to the pulp.
Root canal: The canal in the root of the tooth is where the nerve and blood vessels travel with nutrients to the tooth from the mandible or the maxilla.
Ligament: The connective tissue that surrounds the root of a tooth and connects it to the maxilla or mandible.
Bone: Alveolar bone forms tooth socket and part of the teeth.
Cementum: The layer of tissue covering the dentin on the root of the tooth. Serves the same role as enamel.
Dentin: The calcified tissue underlying the enamel (on the crown) and cementum (on the root), making up the main bulk of the tooth.
Enamel: The calcified outer layer of the crown of the tooth.
Although each tooth has the same basic structure, some variation exists. Different types of teeth have variation in their roots. Incisors and cuspids have only one root. Maxillary (upper) premolar teeth commonly have two roots, whereas the mandibular premolars commonly have one. The premolars may also have two roots fused to look as one. The molars on the maxillary arch have three roots, while, on the other hand, the molars on the mandibular arch have two roots.
