I use a toothpaste for sensitive teeth due to some recessions (due to hard brushing, don't push so hard kids!) The dentist and manufacturer of the toothpaste both recommend you don't rinse post-brush to ensure the numbing agent stays on your teeth.

I can very much recommend an electric toothbrush against brushing too hard. Depending on the model it lets you know when you push too hard. It has helped me a lot.

Also, according to my dentist the receded gums don't grow back which is quite scary.

Oh, but you can grow it back through a gun graft, and I had it done successfully. Healthy gum tissue is removed from the roof of the mouth and uses to build the gum back up where it has receded.

And it is an extremely invasive and painful procedure that should be avoided at all costs if you can. And if you don’t change your habits, you’ll have to have it multiple times.
