In England, becoming a dentist typically takes at least 5 years of education and training. Here are the steps you need to follow:

1. Obtain a Bachelor's degree: The first step towards becoming a dentist in England is to obtain a Bachelor's degree in dental surgery (BDS) from a dental school that is approved by the General Dental Council (GDC). This typically takes 5 years.

2. Complete foundation training: After obtaining a BDS degree, you will need to complete a one-year foundation training program, which provides you with supervised clinical experience in general dental practice.

3. Register with the General Dental Council (GDC): Once you have completed your foundation training, you will need to register with the GDC, which is the regulatory body for dentists in England. You will need to meet the GDC's requirements, including demonstrating good health and character, and passing the GDC's registration examination.

4. Complete additional training: Many dentists choose to undertake additional training to specialize in a particular area of dentistry, such as orthodontics or oral surgery. This can involve completing a Master's degree or a postgraduate diploma in the relevant area of specialization.

5. Continual Professional Development (CPD): Dentists in England are required to engage in continual professional development (CPD) throughout their careers to ensure that their skills and knowledge remain up-to-date. This can be achieved through a range of activities, including attending conferences and workshops, taking courses and undertaking further education.

Overall, it takes a minimum of 5 years to become a dentist in England, but the time frame can vary depending on the specific route you take and your individual circumstances.
