It's so sad that most dentists optimise for billable revenue, even at the detriment of long term patient health. Fillings for example always degrade and need repairs after X years. Drilling and filling even the smallest cavity puts that teeth on a lifetime progression to bigger and bigger fillings, eventually a root canal, eventually an implant. Cavities, on the other hand can be arrested (stopped), and if small can…
My dentist simply put me on toothpaste with high fluoride (IIRC 8%?). Two caries remineralized over the span of about a year and I didn't need fillings. Unfortunately high fluoride toothpastes require an RX.
I just take fluoride pills after brushing in the evening. Common here in Norway a least. Tastes great too, it's like a small treat before bedtime.
Has worked great, have never had a cavity.
