- 5. The upper teeth protrude significantly over the lower teeth.
- 7. Stress, anxiety, or sleep disorders can cause teeth grinding, usually during sleep. A dull headache or sore jaw can be symptoms.
- 9. Inflammation of the deeper structures of the teeth (periodontal ligament, jawbone, and cementum). Poor oral hygiene is usually to blame.

- 2. When one or more teeth become sensitive to hot or cold, it may mean the dentin is exposed.
- 3. Bacteria evade removal by brushing and saliva and damage the enamel and deeper structures of teeth. Most cavities occur on molars and premolars.
- 6. The lower teeth protrude significantly past the upper teeth.
- 8. Inflammation of the surface portion of the gums, around and between the crowns of the teeth. Plaque and tartar buildup can lead to gingivitis.
