Receding Gums and Gum Graft: Can Receded Gum Grow Back?

Causes of Gum Recession

Gum recession, where the gum margin moves down and exposes more of the tooth root, has several causes, and they split into what a patient can control and what they cannot. Aggressive brushing, particularly a hard-bristled brush used with heavy pressure or an incorrect angle, is a controllable cause. Periodontal disease is another common cause, and it is not always within a patient's control once inflammation has damaged the supporting tissue. Tooth position, naturally thin gum tissue, and teeth grinding can all contribute as well, and none of those are things a patient chooses.

Recession is not always a sign of active gum disease. It can also come from brushing trauma or from where a tooth sits in the jaw, with no periodontal disease present at all, and the treatment approach differs depending on which cause applies, which is why a dentist examines the site rather than assuming one cause.

Brushing-related recession and periodontal-disease-related recession can look similar to the person experiencing them, both showing as a tooth that appears longer than before, but a dentist distinguishes them by checking for the inflammation, bleeding and pocket depth that indicate active disease. A single tooth with recession and no other signs of gum disease is more likely a brushing or positional cause; recession spread across several teeth alongside bleeding and swelling points more toward periodontal disease as the driver.

Naturally thin gum tissue is worth explaining separately, since it behaves differently from the other causes. Some people are born with a thinner band of gum tissue covering the bone at certain teeth, which gives that tissue less of a margin before the underlying root becomes visible, even with careful brushing and no gum disease. A dentist checking for this looks at the tissue thickness itself, not just the visible recession, since it changes how at-risk a site is of further recession over time regardless of technique. Teeth grinding contributes through a different mechanism again, by putting uneven pressure on the teeth and surrounding bone, which some clinicians link to recession at the affected teeth over time, though the exact mechanism is still an area of ongoing clinical discussion rather than a single settled figure.

Symptoms and Root Exposure

Recession exposes the root surface of the tooth, which is not protected by the hard enamel that covers the crown, and sensitivity to cold, sweet or acidic food and drink often follows. This kind of sensitivity is genuinely common: a systematic review and meta-analysis of 65 papers covering 77 studies reported an average prevalence of 33.5% (95% CI 30.2 to 36.7%) for dentine hypersensitivity in adults, with a more conservative best estimate of 11.5% (95% CI 11.3 to 11.7%) (Favaro Zeola et al., 2019, Journal of Dentistry).

Both figures are worth knowing, since the average across all the included studies (33.5%) and the more conservative best estimate (11.5%) tell a different story about how common the symptom really is; neither number on its own should be read as the definitive rate. Either way, sensitivity at the gum line is common enough that it is worth mentioning at a dental visit rather than assuming it is unusual.

Can Gums Regrow on Their Own?

No. Gum tissue does not regenerate on its own once it has receded, and a gum graft is a surgical procedure that covers the exposed root with tissue, rather than the gum growing back naturally. This is a hard answer, not a "sometimes."

What can be done without surgery is stopping the recession getting worse: changing to a soft brush and a gentler technique, having any remaining plaque and calculus removed, and getting any active gum disease under control. That addresses the cause going forward, but it does not restore gum tissue that has already been lost; only a graft covers already-exposed root.

This is worth stating clearly because it is a common point of confusion: a product or technique marketed as helping gums "grow back" without surgery is making a claim this page's evidence base does not support. Ahpra's advertising guidelines require any such claim to be backed by acceptable evidence, and there is no published evidence behind a non-surgical method restoring already-receded gum tissue. Stopping further recession is a genuinely achievable, worthwhile goal on its own; it is a different goal from reversing recession that has already happened.

Gum Graft Options and What Determines the Cost

A gum graft covers exposed root surface with tissue, most often taken from elsewhere in the patient's own mouth (an autograft) or from a processed donor source, and it is itemised under ADA item 235 (gingival graft, per tooth, implant or extraction socket). There is no official schedule of private dental fees in Australia, so no statewide graft price applies; a genuine figure comes only from a clinic's own written quote, dated and specific to the case.

Which source the dentist recommends depends on how much tissue the site needs, how thick the surrounding gum already is, and the patient's own preference once both options and their trade-offs are explained. An autograft has the longest clinical track record and does not carry any donor-tissue consideration, at the cost of a second healing site in the mouth during recovery. A donor tissue graft avoids that second site, which some patients prefer, and the dentist can explain how the specific product used at that practice is processed and sourced if that is a consideration for the patient.

Whether a graft is worth pursuing for a specific case depends on how much root is exposed, how thick the remaining gum tissue is, whether the recession is still actively progressing, and how much the sensitivity or appearance is affecting the patient, all of which is a clinical assessment rather than something to decide from a description alone. Recession that appears or worsens over weeks, especially with pain, pus or a mobile tooth, needs an urgent appointment rather than waiting; slow, symptom-free recession can be assessed at a routine visit. Ask for a written, itemised quote showing ADA item 235 before deciding, and see gum disease treatment in Tasmania for how gum disease itself, if present, is treated first.

A gum graft is carried out under local anaesthetic, and mild soreness and swelling at both the graft site and, for an autograft, the donor site afterwards is expected, with the clinic providing aftercare instructions for managing it. The grafted tissue needs to attach and settle before it is considered healed, and the treating dentist sets the review schedule individually rather than working to one fixed timeline, since healing speed varies by graft type and the size of the area covered. Keeping the area clean without disturbing the graft, and avoiding hard or crunchy food near the site in the early period the clinic specifies, are the main things asked of a patient during healing.
