A boil on the gum is called intraoral dental sinus, or more commonly, a gumboil. Complications
The most common complications of boils are scarring and infection or abscess of the skin, spinal cord, brain, kidneys, or other organs. Infections may also spread to the bloodstream (bacteremia) and become life-threatening. S. aureus strains first infect the skin and its structures (for example, sebaceous glands, hair follicles) or invade damaged skin (cuts, abrasions). Sometimes the infections are relatively limited (such as a stye, boil, furuncle, or carbuncle), but other times they may spread to other skin areas (causing cellulitis, folliculitis, or impetigo). Unfortunately, these bacteria can reach the bloodstream (bacteremia) and end up in many different body sites, causing infections (wound infections, abscesses, osteomyelitis, endocarditis, pneumonia) that may severely harm or kill the infected person. S. aureus strains also produce enzymes and exotoxins that likely cause or increase the severity of certain diseases. Such diseases include food poisoning, septic shock, toxic shock syndrome, and scalded skin syndrome. Almost any organ system can be infected by S. aureus. Squeezing or cutting boils in the danger triangle of the face can be particularly dangerous if done outside a medical setting, as blood vessels in this area drain into the brain and can carry serious infections there.When a boil bursts, a seemingly solid, whitish colored pus initially appears then the pus and some blood follows. Causes
Bacteria
Naturally the cause is bacteria such as staphylococci that are present on the skin.
Hypersalivation, or ptyalism, also known as sialorrhea or hypersialosis is the excessive production of saliva. It has also been defined as increased amount of saliva in the mouth, which may also be caused by decreased clearance of saliva.Hypersalivation can contribute to drooling if there is an inability to keep the mouth closed or difficulty in swallowing (dysphagia) the excess saliva, which can lead to excessive spitting. Hypersalivation also often precedes emesis (vomiting), where it accompanies nausea (a feeling of needing to vomit). Causes
Excessive production
Conditions that can cause saliva overproduction include:
Rabies
Pellagra (niacin or Vitamin B3 deficiency)
Gastroesophageal reflux disease, in such cases specifically called a water brash (a loosely defined lay term), and is characterized by a sour fluid or almost tasteless saliva in the mouth
Gastroparesis (main symptoms are nausea, vomiting, and reflux)
Pregnancy
Fluoride therapy
Excessive starch intake
Anxiety (common sign of separation anxiety in dogs)
Pancreatitis
Liver disease
Serotonin syndrome
Mouth ulcers
Oral infections
Sjögren syndrome (an early symptom in some patients)Medications that can cause overproduction of saliva include:
aripiprazole
clozapine
pilocarpine
ketamine
potassium chlorate
risperidone
pyridostigmineSubstances that can cause hypersalivation include:
mercury
copper
organophosphates (insecticide)
arsenic
nicotine
thallium

Decreased clearance
Causes of decreased clearance of saliva include:
Infections such as tonsillitis, retropharyngeal and peritonsillar abscesses, epiglottitis and mumps. Problems with the jaw, e.g., fracture or dislocation
Radiation therapy
Neurologic disorders such as Amyotrophic lateral sclerosis, myasthenia gravis, Parkinsons disease, multiple system atrophy, rabies, bulbar paralysis, bilateral facial nerve palsy, and hypoglossal nerve palsy

Treatment
Hypersalivation is optimally treated by treating or avoiding the underlying cause.
