The aim of this information sheet is to provide information for parents on keeping their heart child’s teeth healthy.
What have teeth got to do with the heart?
Our mouths are full of bacteria that build up on the teeth in a sticky layer (plaque). These bacteria feed off the sugar in our food and drink and convert it into acid which can cause tooth decay. Bacteria also make the gums inflamed and cause gum disease.
Tooth decay and gum disease (dental disease) can cause a disease of the heart called infective endocarditis. This is an infection of the inner lining of the heart caused by bacteria in the bloodstream.
Dental disease can push large numbers of bacteria into the bloodstream. Large numbers of bacteria in the bloodstream can then lead to infective endocarditis. Infective endocarditis is a rare but life-threatening disease.
Children with heart conditions are more at risk of infective endocarditis. It is therefore very important for heart children to take good care of their teeth.
How can you prevent dental disease?
1. Limit sugar in the diet
Some children with heart conditions may have feeding problems, and it may be more important for them to get enough calories than to maintain a healthy diet. These children may be eating lots of sugary foods to maintain a healthy weight. If this is the case, make sure that your child brushes their teeth well and often and goes to the dentist regularly.
2. Tooth brushing
3. Register with a dentist:
Dental disease and heart conditions
Certain heart conditions will make children more vulnerable to dental problems. Ask your child’s cardiologist if they have a higher risk of developing dental disease.
Children are treated free under the NHS. To find an NHS dentist in your area, ring NHS 111.
