These are the stages of gum disease:

1. Red and swollen gums that bleed when you brush them are a sign of a type of gum disease, gingivitis.
    

2. When gingivitis is left untreated it can develop further into a type of infection known as periodontitis, which affects the entire area surrounding the tooth, causing discomfort and difficulty when eating
    

3. Eventually this kind of infection can lead to tooth loss and may require invasive procedures to replace the missing tooth.
   
   Fortunately, this can be avoided by attending regular hygiene check-ups at the practice and maintaining a good daily hygiene routine. Brushing between the teeth, flossing and replacing your toothbrush every three months will also benefit your gum health.
