When a tooth is infected and pus is formed in the roots of the tooth, it is called an abscess. The reason for the formation of pus is the bacterial infection in the soft pulp of the tooth. The following are the factors that can cause bacterial infection in the soft pulp, cause dead pulp tissue, and hence cause tooth abscess:
- Dental caries
- Cracked teeth
- Periodontal disease
- Unsuccessful root canal
- Unsuccessful dental restoration, when bacteria enters into the tooth filling and triggers the infection
Types of tooth abscess
There are basically three types of tooth abscess:
- Gingival abscess: This is when only the gum tissue is affected by the infection.
- Periapical abscess: starts from the root of the tooth
- Periodontal abscess: This starts from the gum pockets
- Tooth abscess causes constant pain, particularly when force is applied or when warm items are eaten or drunk.
- Swelling in the gums, at the base of the tooth, and even the cheeks. Swelling of the face is also possible in some situations, such as when the abscess affects the bone, and then spreads to the other connected tissues
- Migraine-like pain, which would be transferring from the infected area
For the treatment of tooth abscess, the organisms causing the condition would be removed or reduced. Use of antibiotic medication is very supportive. Drainage is also among the treatment techniques. Root canal treatment can also be a possible treatment for tooth abscess if restoration is feasible. When the restoration of the tooth is not a probability, then the tooth should be extracted before it causes more discomfort and damage.
