@Dave7 it sounds like you've had some a tuff all time and dental pain is one of the worse things you can have. Hopefully things will settle and you can at least have some respite from the worse of the pain.
Who ever was having a go clearly has not asked around.
All Dental staff within hospitals have been redeployed as for the rest many are not on furlough they've signed up to be redeployed.
Dentists have plenty of skills that are transferable. NHS England has full guidelines about it.
Wound care , Note taking, basic clinical obs, routine jabs, if you end up in A and E and need sedation say for a dislocation it maybe a dentist that you see. Need your bloods taking ? well that maybe a dentist too. Some Dentists are also acting as HCA.
Dental Nursers and others have also been able to be asked to be redeployed.
The Chief Dental Officer ordered all treatment to cease as of the 20th march.
The main issue is any treatment involving AGP full level 3 PPE is required. AGP's are just too risky without a lot of measures being in place and are currently not being allowed to take place. Removing teeth is not a AGP for example so can be offered but only ones by hand. For crowns the tooth may need restorative work which is an AGP. Working in a shop is in no way the same risk as this is. AGP's are not only a risk to staff but to the patient and others who came next.
For a simple check up current day to day PPE maybe fine but we've learned in many cases "low risk" is anything but. So may start to be offered at some point but can only be one person in and one person out and a total clean down each time the treatment room , waiting room and other areas that come into contact with you. So very limited service maybe possible. But even if more open to do basic treatment only. Level 3 PPE will still need to be in place for emergency situations such as CPR. (even if PHE have now downgraded as not a AGP)
Emergency treatment be it limited is happening though it's not universal via a network of Urgent Treatment Centres around 100 are planned. 3 levels are being used , red for covid/mayhave and households with covid/mayhave. Amber for at risk groups and blue for everyone else. Even then it may well be miles away from you and most likely not your own practice. The default treatment via your surgery should be general advice pain management , or other temporary solutions like advising patients to use temporary fillings the type you can buy from the chemist. Or even directing patients if they have sharp edges to use a nail file.
The 3 level approach is here to stay for some time as like many other health services they will have to find ways to carry no working but in covid active environments. Even rinsing your month out after treatment won't be happening for a good while yet. Basically it will come down to capacity and if you can get hold of enough PPE.
