You can prevent gum disease by controlling the amount of plaque and tartar that builds up on your teeth. Regular visits to your dentist or hygienist, brushing and flossing your teeth properly and stopping smoking will help to do this.
Dental floss or inter-dental brushes can remove plaque and small bits of food from between your teeth and under your gum line – areas that a manual toothbrush can't reach. You may prefer to use an electric toothbrush. There is some evidence to suggest that certain types of electric toothbrush may be more efficient at removing plaque than manual toothbrushes. It’s important to use the correct technique, so ask your dentist or hygienist for advice.
Some antiseptic mouthwashes reduce the amount of plaque bacteria when combined with regular brushing and flossing. However, there isn’t currently enough evidence to say whether mouthwash can help prevent gum disease. If you do use an antiseptic mouthwash, it's important that you don't use it for too long as it can stain your teeth. Always read the information on the mouthwash box or bottle and if you have any questions, ask your dentist or hygienist for advice.
Even thorough brushing and flossing can't remove every trace of plaque as most people have irregularities in their teeth where plaque can build up out of reach and harden into tartar. This can only be removed by your dentist or hygienist during scaling.
