The government's guidance states that “a number of public services will also stay open and you will be able to leave home to visit them. These include [...] the NHS and medical services like GPs”. Sara Hurley, England's Chief Dental Officer, has confirmed this includes NHS dental services.
This means that during periods of tighter restrictions, dental practices should remain open to treat patients. If you are concerned about your dental health or have a dental emergency, you should be able to travel to a dental surgery for treatment.
However, it's important to check with your dentist before traveling to make sure your concern is considered urgent, and that they are able to treat it.
You must not travel if you are experiencing any coronavirus symptoms, are self-isolating as a result of coronavirus symptoms, are sharing a household or support bubble with somebody with symptoms, or have been told to self-isolate after being contacted by NHS Test and Trace. The fine for breaching self-isolation rules start at £1,000. This could increase to up to £10,000 for repeat offences and the most serious breaches, including for those preventing others from self-isolating.
If you do travel, you are encouraged to walk or cycle where possible, and to plan ahead and avoid busy times and routes on public transport. This will allow you to practise social distancing while you travel.
