Five signs of infection:
- Serious toothache when eating, or when you put pressure on the tooth. Does it hurt when you bite down hard?
- Excessively sensitive teeth. Does the sensitive pain linger after the initial contact with hot or cold foods or drinks?
- Darkening of your tooth. Has your tooth changed colour? This may be a sign of the nerve dying.
- A small bump on the gum, close to the painful tooth.
- Tender or swollen gums around the tooth.
