Mouthwash is a fluid hygiene product recommended to help you with your oral health regime.  It has been used throughout history, reports date from 2700BC of the Chinese using a fluid to help clean the mouth.  Modern mouthwashes gained in popularity since the 1960’s with the discovery of chlorhexidine.  Generally mouth washes help to dislodge and food debris and freshen breath although there are some that have been specifically formulated to help you with certain problems. These include specialisations in anti-cavity formulas containing fluoride, dental plaque reduction and gum disease prevention.  Mouthwashes are not a brushing or flossing substitute.  You need to utilise all three to maintain a healthy mouth.

Use of Mouthwashes

  • Plaque prevention.  Plaque is colourless and builds up gradually on the tops and outer surface of your teeth.  It is essentially a film of organisms and bacteria that breed continuously and spread over your teeth.  If left unattended plaque transforms into a very hard substance called tartar that requires dental intervention to remove.  In extreme cases tartar build up can lead to tooth extraction as it provides an ideal breeding environment for the bacteria and organisms that constitute plaque, so leading to an endless cycle. 
  • Gum disease treatment.  Some infections and mouth problems can be alleviated using specialist mouthwashes high in Chlorhexidine content.  These can only be used in small amounts and shouldn’t be used over a long period of time.  Prolonged use can cause discolouration to the teeth, although if this occurs a hygienist can usually treat it quickly and effectively.
  • Freshening breath.  This is the usual reason for using mouthwash, most contain a breath freshening flavour such as mint.
