If gingivitis is left untreated it may develop into periodontitis. Periodontitis has all the symptoms/signs of gingivitis
but deteriorates further as plaque bacteria slides down the tooth root, underneath the gum and starts to eat away at the bone which holds the tooth in. This causes the gum to split away from the tooth and form deep pockets which may result in gum abscesses, gum shrinkage (recession) and finally loose or drifting teeth. Tooth roots will become exposed making them more susceptible to root decay and sensitivity. You are at an increased risk to gum disease if you smoke, are stressed or take some perscribed medications which are known to irritate gums.
