Tooth Cyst Treatment
What is a tooth cyst really?
Tooth Cyst Treatment
A dental cyst is a closed sac filled with fluid, which usually forms at the tip of the tooth root as a result of a prolonged infection or an untreated damage to the tooth nerve.
How is a cyst formed?
When the tooth nerve becomes infected or dies (necrotizes), bacteria and their toxins pass beyond the root, causing inflammation of the surrounding tissue. If this process continues for a long time, the body forms a protective "sac" around the infection — and thus a cyst is created.
Signs and symptoms
- Often, the initial cyst does not show symptoms. But as it grows it can cause:
- Swelling or pain in the surrounding area
- Sensitivity during biting
- Facial or neck pain (in large cases)
- Change in bone shape
- Presence of a fistula (small channel that drains pus)
Is it dangerous?
Yes, if left untreated. The cyst can: increase infection, damage surrounding bone, push or damage roots of adjacent teeth, grow to considerable size.
How is it treated?
- Root canal treatment – when the cyst is associated with an infected tooth.
- Root canal retreatment – if previous treatment has failed.
- Cystectomy (surgical removal of the cyst) – when the cyst is large, persistent, or does not disappear after endodontic treatment.
- Tooth extraction – in rare cases, when the tooth cannot be saved.
Does it disappear on its own?
No. The cyst does not heal on its own and always requires professional treatment.
