Should I use a soft toothbrush?

If you have been using harder brushes up to this point, I'm surprised you even have teeth left. Softer brushes don't damage your teeth as much and they are gentler on your gums, too. I myself have such sensitive gums that every time I get a new brush (always soft), my gums bleed the first few times I use it. I'm thinking of permanently switching to extra soft tooth brushes.
