Oral hygiene & saliva management

Oral hygiene means keeping your mouth (teeth, tongue, gums, and roof of your mouth) clean and healthy. Your mouth should be pink and moist.

Why is oral hygiene important?

Oral hygiene maintains healthy teeth and limits the growth of bacteria in your mouth.

The oral bacteria in your saliva, food, and liquids can go into your airway. This is called aspiration. This may increase the risk of lung infection.

Oral hygiene is important for everyone, particularly people who have swallowing difficulties. It is very important for people who cannot eat and drink (nil by mouth, or NBM).

Changes in saliva

FDP toothbrushYou may have a dry mouth, or excess saliva. It can be runny, or thick and stringy. You may find it difficult to swallow your saliva. This can lead to drooling, especially if your facial muscles are weak.
