several misconceptions here
child fillings are done routinely on the NHS , however on such a young child co,operation is key and also size of filling . Not all baby teeth can be saved and a 3 year old with decay in a molar that supposed to last for another 7 years that needs a general anaesthetic is far better off having the tooth removed than a repeat GA as most baby molars that have large holes will already have a dead nerve and the start of an abcess.
Dentists did not shut down over covid. In our area between end of March 2020 and May 2020 we could provide emergency treatment ,in our practices ,only and after that provided all treatment but with added precautions that drastically reduced number of,patients we saw despite working increased hours. In many areas dentists were relocated to working in dental access centres which were better set up for aerosol proceedures between March and May 2020.
Until end of 2021, beginning 2022 anything that generated an aerosol (drilling) meant special precautions including gowning up , using respirators and leaving a room fallow after each treatment for up to two hours. This drastically reduced the number of people a day a dentist could see. Coupled with the fact dentistry was the highest risk for clinicians to catch covid staff illness also impacted number of patients seen a day .
Dentists were not eligible for furlough payments , full stop . Most are still paying the debts incurred through decreased income and paying for the ventilation , foggers and other equipment necessary to meet covid regulations to practice.
This is what every dentist and staff wore in my area all day every day during covid . We were exhausted . I lived in a caravan on my drive so I didn’t pass infections onto family as dentistry was deemed to be so high risk . This was the same for every dentist I know and the toll taken on our health is why so many of us have had to retire early , exhausted .
