I have a small amount of gum recession around one tooth (I suspect it is from brushing too hard, since it's on the left side of my mouth and I'm right-handed). It's not really noticeable, but it does cause slight pain when there's pressure or friction against the gum line (basically only when I press on it). It is not sensitive to temperature. I have no other gum problems (no gingivitis). There is also no bone loss - only the gum.

I have a dentist appointment tomorrow, and I was wondering if someone who's experienced something like this knows what I should ask for by way of treatment. Medical professionals don't always give a treatment unless the patient specifically asks for it, and I find this gum recession quite upsetting.

I know skin grafts are sometimes performed for gum recession, but this is a very mild case, so I doubt that will happen. What is a milder treatment, if there is one? Or can something like this heal on its own? Can gum tissue grow back naturally, and can the receding gum line reattach to the tooth?

Some websites give "stop brushing so hard" as advice, but will this allow the receded gum to grow back, or merely stop further recession?
