A white bag in the upper tooth chamber may be related to physiological factors, or it may be caused by periapical inflammation, mucous gland cysts, oral tumors and so on.
1. Physiological factors: For example, if you have recently consumed hard food or food that is too hot, which may easily lead to localized chitinous injury or burns on the upper tooth cavity, it may lead to a white bag on the upper tooth cavity.
2. Periapical inflammation: due to the inflammatory reaction of the tissues around the root apex, which may lead to localized abscess in severe cases, which may cause a white bag on the upper tooth chamber, and may be accompanied by occlusal pain, poor appetite and other manifestations.
3. Mucous gland cysts: usually caused by the obstruction of the gland that secretes saliva or injuries in the oral cavity, which may cause a white bag on the upper teeth, and may be accompanied by difficulty in chewing, unclear speech and other manifestations.
4. Oral tumor: some oral tumors may cause the local mucous membrane of the oral cavity to be enlarged, which may lead to a white bag on the upper teeth, and may be accompanied by oral pain, oral ulcers and other manifestations.
If you have a white bag in your upper teeth, you should consult a doctor as soon as possible after excluding physiological factors.
