No, your gum tissue does not grow back. I’m assuming you are talking about recession due to agressive brushing. This is very common. When you have recession your gum tissue is “worn away” and the root surface is exposed. This can cause sensitivity. This is due to the porous nature of the root surface. Sensitivity toothpaste or a fluoride varnish applied at the dentist can help treat the symptoms. The only way to repair the recession is a tissue graft, usually tissue from the palate is used. This is not usually necessary. You have a band of “attached gum tissue”. This is the pink firm gum tissue right at the base of the tooth. Next you have “free gingiva”. This is the redder movable tissue past the attached gingiva. If the recession only involves the attached gingiva and you still have an attached zone around the tooth, a graft is not usually necessary. The best thing you can do at this point, if you have recession, is modify your brushing. I like a good electric brush, like a Sonicare, and use light pressure while using it. For manual brushing, use a SOFT bristle brush. Angle the brush at a 45 degree angle to the tooth. Starting at the gum tissue lightly “vibrate” the brush down the tooth. NEVER scrub back and forth. It should take you 2 minutes to brush your teeth properly. This brushing technique is called the “modified Bass” technique. Also, when you floss, “see-saw” the floss back and forth to get through the contact points. Don’t snap it down on the gums.
Just a side note, if you already have recession and make no effort to modify your brushing you will most likley experience abrasion next. This is when the root surface begins to wear away due to agressive brushing (other causes are possible). The root surface is softer and will wear faster than enamel. It will begin to get notched out like when you begin to chop a tree down. Again, sensitivity is possible and fillings are many times necessary.

well in 1st place y would u wanna brush away ur gums? its not healthy to brush too hard as it can cause both abrasion cavities n gingival recession. n once gum recession happens, the gums wont grow back but only further recession can be stopped if u follow the right way of taking care of ur oral health.

Mine never did but they say the older you get the further back your gums recede

I believe so. A very very small part of my gum was worn away, and I’ve been taking care of my teeth, and felt just now, and the gum felt normal there.
I’m sorry I don’t have any official sources, but I’ll still happily share personal experiences!

it’ll grow back on its own dont worry
dont listen to anyone else, i have done that before, my gums have peeled before and they were really bad i thought, but i took care and they do grow back or they heal over or whatever

Yes, your gums are like most things in your body and can rejuvenate or grow back. Several factors effect this such as diet, care, exercise overall health and age! Most importantly keep those teeth clean and floss, use mouth wash and swab betadine around each toothline for added maintenance.

no – you don’t grow them back but it is o.k. always floss

A cut gum will heal, after a tooth pulled the gum may fill in the gap but if the gum is missing it will not grow back. I know this from personal experience and too many years of hard brushing. You must be gentle on your gums. If they grew back then I wouldn’t have this mouthful of implants instead of my permanent teeth. My daughter wouldn’t be facing gum grafts because an oral surgeon cut too much away when she was younger.
Be careful with your gums.

It can go back a little only. But one can correct it with surgery, but also then it might return if you brush the same way. It’s called mucogingival surgery.
