Yeah! And remember that there are also spaces between teeth! They often / usually contains some remains that would like to destroy your teeth. I am using brush, inter-teeth brush and floss - all 3 of them, and it even feels great. Andrew Steele greatly described the problems of bad teeth cleaning in his book Ageless, even though that was small part of the book.
When you are now below 30, you have reasonable chance to live way beyond 100 in good health! Well, if you choose to use the new medicine interventions (that are now in research and development or concepted) after they are available. I mean decades beyond 100!
Most current people above 50 does not understand it because they are too socially programmed. But you, with fresher mind, can break from their dogma.
Learn a little bit about Longevity Escape Velocity (LEV) to understand it. Because it is going to be one of the most defining things in your life!
If you want also your parents to be alive very long, the progress must be much quicker. You may request your government to invest heavily into real aging-reversal therapies. And ask your friends and random people on internet (😉) to do so. But chances are that your parents are too old to have good chance to get to LEV. In that case you may talk with them about cryopreservation and help them to sign for some provider. Currently it is far from certain that we will be able to revive them in the future, but alternative is a grave / cremation with total clarity of no revival at all.
