Depending on the location, dental caries are not always visible in the mouth. Initially people may not experience any symptoms, or mild sensitivity to temperatures and sugary foods. Pain is often only felt when dental caries has progressed inwards and is close to or involving the pulp (nerve) of the tooth.  

Dental caries are preventable through good oral hygiene and a low sugar frequency intake. Brusing twice daily with a fluoride containing toothpaste and cleaning in between your teeth with cleaning aides like floss or interdental brushes can keep your mouth free from plaque buildups and food debris. Limiting the number of times you consume sugar will also lower your risk, as it reduces the number of times your teeth are exposed to the harmful effects of sugar. Taking steps to reduce snacking in between meals or opting instead for a tooth friendly snack such as cheese or yogurts will help. Additionally chewing sugar free gum or rinsing your mouth with a fluoride containing mouthwash after eating is also beneficial. Chewing sugar free gum will produce more saliva which in turn helps to rid the mouth of debris. 

It is important to be mindful that many foodstuffs, medications, and supplements contain a high sugar content. This is particularly true for oral nutritional supplements often prescribed to people with cystic fibrosis to maintain a healthy weight. These can contain up to 35gs of sugar per servings depending on the supplement prescribed. It is important to inform your dentist if you are prescribed an oral nutritional supplement. If you are experiencing high levels of dental caries, your dentist can liaise with your doctor to discuss alternative supplements that may be less harmful to your teeth. A toothpaste containing high levels of fluoride may also be recommended for you.  

If left untreated dental caries can cause pain, infection, and even lead to tooth loss. By seeing your dentist regularly and keeping them up to date with your medications and treatment, you can lower your risk of dental caries.
