Gingivitis and periodontitis
Gum disease is a very common condition where the gums become swollen, sore or infected.
Healthy gums should be pink, firm and keep your teeth securely in place. Your gums should not bleed when you touch or brush them.
Gum disease can be caused by a number of factors, but poor oral hygiene is the most common cause.
The best way to treat gum disease is to practise good oral hygiene, although additional dental and medical treatments are sometimes necessary.
If you develop gingivitis and do not have the plaque or tartar (hardened plaque) removed from your teeth, the condition may get worse and lead to periodontitis.
