Genetically I have been blessed with straight, even white teeth, no gaps.
The best way to keep them in good nick is daily effort and attention, no junk food, snacking (which is so common nowadays, everything is geared up to tempt people to eat rubbish, it takes will power not to slip into bad habits.
During the pandemic when I couldn't get to a checkup for nearly 2 years, I
developed Gingivitis (gum disease, inflamed gums) which if left untreated is far more harmful than tooth decay. People lose more teeth to gum disease than decay. The root cause is insufficient attention to cleaning the backs of teeth, and right up to where the gum and teeth meet which causes bacteria to accumulate, the gums to recede from the tooth and ultimately leading to bone loss so the tooth becomes loosened from the jaw.
I have been using 3 different colours of Tepe which the dentist recommended-red, yellow and green which are different thicknesses to get in between the top of the teeth, plus floss to do the whole space. I'm a bit obsessed now and carry flossing harps and a yellow tepe in my work bag
I'm careful not to snack if I can't clean my teeth afterwards.
I take about 10 mins a night to do a full clean. 100% agree about being gentle, vigorous brushing causes lasting damage.
i have a 6 monthly clean at the hygienist and try to have a 6 month dental check up if there's availability. I'm shortly going onto a den plan through work which will cost £9/month for 6 monthly check ups I'd pay 4 times that, it's such a good investment.
good heart health is linked to good oral hygiene.
