The main symptom of caries, or tooth decay, is pain. Often the pain appears after the damage to the tooth has already begun.
The type and intensity of the pain varies, depending on the level of decay.
An acute, brief pain indicates the start of caries. Generally, it is triggered by a specific event, such as eating something hot or cold.
The deeper the decay, the more intense the pain. The pain from tooth decay can be dull or throbbing.
When the caries reaches the dental pulp, the pain becomes continuous and piercing.
Other symptoms associated with caries are:
- The presence of a small pit, or hole, in the tooth.
- Food deposits between teeth.
- Sensitivity to hot and cold food and beverages.
- Bad breath (halitosis).
- Bitter taste in the mouth.
- Swelling of the gums.
- Facial swelling with enlarged glands in the neck.
