Dental Carries

  • Dental carries are the holes or cavities that are formed as acid corrodes enamel and eventually the dentine


  • This is caused by bacteria acting on the food left between teeth and on the cusp
  • Acids are formed that eventually corrode the enamel
  • The pulp cavity is eventually reached
  • A lot of pain is experienced then
  • The bacteria then infect the pulp cavity and the whole tooth decays


  • Treatment depends on the extent of the dental caries:
  • Extraction of Tooth
  • Filling – this involves replacing the dentine with amalgam, a mixture of hard elements e.g silver and tin
  • Root Canal Treatment – This involves surgery and reconstruction
  • It saves severely damaged teeth
  • The nerves in the root canal are surgically severed
  • The tooth is cleaned and filled up with amalgam

Periodontal Diseases

  • These are diseases of the gum
  • The gum becomes inflamed, and starts bleeding
  • Progression of the disease leads to infection of the fibres in the periodontal membranes and the tooth becomes loose
  • This condition is known as pyorrhoea
  • The diseases are caused by poor cleaning of the teeth
  • The accumulation of food particles leading to formation of plaque, lack of adequate vitamin A and C in the diet


  • Nutrition – by taking adequate balanced diet rich in vitamins A and C
  • Antibiotics are used to kill bacteria
  • Anti-inflamatory drugs are given
  • Antiseptic is prescribed to use in cleaning the mouth daily to prevent further proliferation of bacteria
  • The plaque is removed-drilled away – a procedure known as scaling

Care of Teeth

In order to maintain healthy teeth the following points should be observed:

  • A proper diet that includes calcium and vitamins, particularly vitamin D is essential
  • The diet should also contain very small quantities of fluorine to strengthen the enamel
  • Large quantities of fluorine are harmful
  • The enamel becomes brown, a condition known as dental flourosis
  • Chewing of hard fibrous foods like carrots and sugar cane to strengthen and cleanse the teeth
  • Proper use of teeth e.g. not using teeth to open bottles and cut thread
  • Regular and thorough brushing of teeth after meals
  • Dental floss can be used to clean between the teeth
  • Not eating sweets and sugary foods between meals
  • Regular visits to the dentist for check┬Čup
  • Washing the mouth with strong salt solution or with any other mouth wash with antiseptic properties
