It is recommended that as soon as a child's teeth start erupting they should attend the dentist for the first time. Ideally, children should see a dentist for the first time no later than 2 years old.
Although it is rare for dental problems to occur at such a young age, seeing babies or toddlers this early helps us to detect any growth acceleration/delay or to recognise habits which may affect the child's dentition or development down the line.
It is also a good idea to get children familiar with the dental environment, ensuring it's a positive and consistent experience for them. This ensures they get the best start in life with their oral hygiene, hopefully preventing them for needing any major dental work throughout their lives.
