Unlikely, unless maybe the abscess enters the brain. But more general problems would be expected then.
Abscessed tooth only happens for three reasons; when teeth are damaged such as an untreated cavity, a person brushed their teeth properly, and lastly the gum diseases. Those are the three causes to an abscessed tooth.
Chlamydia doesn't cause dementia.
Herpes doesn't cause dementia.
An abscess is a very bad infection in the root which should be treated immediately. Most commonly cause by severe tooth decay, it can also be formed from gingivitis or when there is trauma to the tooth. Symptoms include fever, sensitivity, pain when chewing, redness and swelling or foul smelling breath. If not treated immediately, the infection can spread to the bone.
Oddly enough, many famous people have died from an abscessed tooth. For example, fashion designer, Hugo Boss, and Jethro Tull musician, John Glasscock, both died from abscessed teeth.
Having the flu
The best antibiotic for an abscessed tooth can depend on how bad the infection is and which the dentist prefers. Sometimes penicillin is best if the infection is bad. Amoxicillin is part of the penicillin family and is associated with the treatment of abscessed teeth.
There is no evidence that Post Polis Syndrome can cause dementia, but PPS sufferers' can develop dementia which is non-related to PPS, such as Alzheimers' Disease.
Most dementia is incurable and irreversible. Forms of dementia that are reversible are caused by a tumor or impairment from drugs or medication.
Abscessed means infection and if it ruptures, this means that fluid will spill in to your mouth which could cause further infection the best thing to do is to see a dentist who will give you antibiotics.
Good question. Ask your psychiatrist, then your dentist, and compare.
We do not know what causes dementia, we only know that it becomes more common as people age.
