This article explains how to keep good germs in your mouth after treatment for decay or gum disease.

Main ideas

• Many mouth problems are caused by bad germs. Diet and cleaning decide which germs live in your mouth.
• Serious problems may need strong treatment: a deep clean, strong mouthwash, gels, toothpastes or antibiotics.
• Strong treatments also kill good germs and can dry the mouth, change taste or stain teeth. So they are only used for a short time.
• After treatment, do not go back to old habits. Build a plan you can keep up.

Good habits

• Eat less processed food. Eat more high-fibre food and a little cheese.
• Drink 2 to 3 litres of water a day, more if active or sweating.
• Brush twice a day with a soft brush and fluoride toothpaste. Clean between teeth and clean your tongue.
• Use a straw for sugary or acidic drinks. Wait 30 minutes before brushing.
• If you have dry mouth or reflux, use special products that repair teeth.
• If tooth roots are showing, use a toothpaste that stops sensitivity and decay.
• You can try a mouth probiotic (good germs).
• See your dentist regularly.
