I used to have this problem. I can’t use wire floss because there is no gap between my teeth… I started using water flossing (basically a pressure washer for your teeth) and paired with an electric toothbrush it worked wonders.
Other notes for a better dental care routine:
Use toothpaste with fluoride.
If you are using the water flossing method, do it before brushing your teeth.
Don’t rinse your mouth after brushing; this is especially useful for brushing your teeth before going to sleep. Don’t drink water afterwards, do it before if you want (obviously if you are feeling dehydrated, drink water, but otherwise let the fluoride do it’s thing).
