The best way to protect gums from gum disease, periodontitis and acute necrotising ulcerative gingivitis is to always practise good oral hygiene.
This means brushing teeth at least twice a day and flossing at least three times a week.

Visiting the dentist
If you have never had gum disease and have good oral health, you may only need to visit your dentist every 1-2 years for a check-up.
It is important you attend dental appointments so any problems with teeth and gums can be detected and treated early.
If you have had problems with gum disease or periodontitis in the past, you may need to visit your dentist more frequently. At each appointment your dentist will advise when you need your next appointment.
If you have an increased risk of developing gum problems - for example, if you smoke or have diabetes (a condition caused by too much glucose in the blood), you may be advised to visit your dentist more often so your teeth and gums can be closely monitored.
