Going to the dentist is not like going to the doctor. Most people only go to the doctor when they are unwell, whilst most people who visit their dentist are well and have no symptoms. This can mean that a visit to the dentist is low on some people's list of priorities.
Anxiety and fear about going to the dentist can also put people off making the appointment. Some people do not know how to find a dentist, whether to be treated on the NHS or privately, what kind of service to expect from the dentist, what treatments are available, and what to do if something goes wrong.
