I agree that the twice yearly NHS dental mouth check is not enough.
For me, the game changer was in an emergency paying for a private assessment with an established dentist who removed a very diseased tooth - rather repeat root canal treatment recommended by my then NHS dentist - & immediately referred me on to a periodontal specialist as although my teeth were OK enough, I had advanced gum disease.
I embarked upon a strict remedial plan with an experienced dental hygienist, learned far better how to look after my mouth & teeth. I now have a clean bill of dental health.
Overall my health has improved, no more bleeding gums, tooth tenderness, mouth soreness or teeth sensitive to cold.
Cost a fortune at the time - had to cancel any holidays plans & discretionary spends for a couple of years - but overall the cost & effort has been well worth it.
My teeth look bright & clean, my mouth feels good, I have a great smile & feel better in myself.
Because I cannot get to see an NHS dental hygienist, I have hard coded into my budget the routine private appointments.
The NHS dental payment schema is deeply flawed, the dental profession is no more happy about this than are patients.
It is a disgrace that state provision of dental care is so patchy & variable.
