In the modern era there have been lot of aspects associated with oral health, especially chronic and acute medical conditions. A lot of studies have been conducted regarding scariest medical conditions related to poor oral habits. The dentists can focus mainly on preventive measures in different ways. The dentists are now dealing with some of the scariest medical conditions including stroke, chronic kidney disease, lung cancer, respiratory infections, Alzheimer’s, breast cancer, oesophageal cancer.


Stroke is an obstruction of total blood flow to the brain and may be acute. Oral bacteria may cause diseases which affect the brain.

Types and symptoms

  • Haemorrhagic stroke
  • Transient ischemic attack
  • Ischemic stroke

Symptoms of stroke

Nausea, vomiting, numbness of face, unstable mind, headache, loss of balance, paralysis on one side of the body, blurred vision, drooping face and dizziness.

Effects on oral health

The effects on oral health include inability to brush teeth, slurred speech, inability to rinse mouth, dry mouth, inability to swallow, loss of teeth and abscess formation.

If it is untreated, the adverse effects are gingivitis, dental caries and periodontal disease. If patients do not take proper care of their oral health, it leads to denture stomatitis, inflammation of the mouth and ulcers.

Chronic kidney disease

The individuals with kidney disease have other health-related issues since their immune systems are compromised, so they are more affected by various infections.


Vomiting, sleep disturbances, swelling of ankles and feet, feeling of itching, weakness, cramps and loss of appetite.

Effects on oral health

The oral health is affected since the kidneys are unable to remove urea from blood and the urea breaks down in order to form ammonia. The changes in the bone density also occur since calcium is not absorbed by body properly. Therefore, people with kidney problems are high-risk. Bleeding gums, halitosis (bad breath), xerostomia, sensitive teeth, salivary gland infection, inflammation of the mouth, tooth loss are the symptoms of gum disease. If it is not monitored periodically, the adverse effects lead to dental caries, abscess formation and periodontal diseases. The other symptoms affecting general health are heart disease, anaemia and eating disorder known as anorexia blood disorder.

The radiation therapy causes stiffness. It would result in dry mouth, gum diseases like gingivitis, sore mouth and more sensitivity. The taste of the food changes.

Respiratory infections

The reservoir has potentially been considered in the oral cavity which is specifically respiratory pathogens. The mechanism of infection of the lungs such as pneumonia, dental plaque colonization by pathogens of the respiratory tract is through aspiration. Along with pathogens of the periodontal region, facilitating dental plaque colonization in the pulmonary tract is also seen.

In the elderly people, the dental plaque colonization due to pulmonary pathogens is more frequent. The reaction leads to variable inflammatory process and connective tissue destruction which is present in emphysema and periodontal disease. There is also strong relation and association between COPD (chronic obstructive pulmonary disease) and periodontal disease. The acute condition such as pneumonia is a gradual onset with little or no fever with a cough.
