There’s a particular kind of dental concern that sneaks up on people. Not a toothache, not a broken filling — nothing that demands immediate attention. Just a vague sense that something has shifted. Your teeth look a little longer. One spot reacts badly to cold. You run your tongue along the gumline and feel a slight ridge where you don’t remember one being before.
That’s often how gum recession announces itself, and by the time those signs are obvious enough to notice, the process has usually been going on for months. Sometimes longer.
It’s one of the more frustrating things to explain to patients, because there’s no dramatic event to point to. No moment it started. According to Cleveland Clinic, roughly 88% of adults over 65 have recession on at least one tooth — which tells you a lot about how quietly it builds up over a lifetime (Cleveland Clinic, 2022). The upside, if there is one, is that catching it changes what treatment looks like significantly. Earlier means simpler. Almost always.
What Is Gum Recession?
Think of the gum tissue as a gasket. It wraps around the base of each tooth, creating a seal that keeps bacteria away from the root. When that tissue starts pulling away from the tooth — shrinking downward — it exposes the root surface underneath.
Here’s the part people don’t always know: root surface isn’t covered by enamel. It’s covered by cementum, which is softer and more porous (Cleveland Clinic, 2022). So when that area becomes exposed, it’s not just an aesthetic problem. Exposed roots decay more easily. They’re more reactive to temperature and touch. And if recession progresses far enough without treatment, it can compromise the bone that holds the tooth in place.
Dentists measure recession in millimetres — using a thin probe to check the depth of the gap between the gum and tooth at multiple points. Even one millimetre matters. That’s why we flag it at routine checkups before patients have noticed anything themselves. It’s much easier to act on one millimetre than five.

What Causes Gum Recession?
This is where it gets complicated, because gum recession rarely has a single clean cause. Most patients have more than one thing contributing.
The most common driver is periodontal disease. Chronic gum infection creates ongoing inflammation, and that inflammation slowly destroys both the gum tissue and the bone underneath. Left untreated, the recession that comes with it can be substantial. The infection itself isn’t always painful, which is part of why it goes unaddressed for so long.
Brushing habits are the other big one — and it’s worth saying directly, because a lot of people brush harder thinking it means cleaner. It doesn’t. A firm back-and-forth motion, especially with a stiff brush, wears gum tissue away over years. Gradually. Without any signal that it’s happening. We see patients who have great hygiene and significant recession, and brushing technique is often a piece of that puzzle.
Then there’s genetics. Some people simply have thinner gum tissue to begin with — a naturally slim periodontal biotype — and there’s not a lot they can do about that baseline. Thin gum tissue recedes more easily, full stop. It’s not a hygiene failure. It’s anatomy (Cleveland Clinic, 2022).
Grinding and clenching are underappreciated causes. The lateral forces from bruxism stress the gum attachment in ways that vertical biting pressure doesn’t, and that matters over time. If you grind at night — and many people don’t know they do — a custom night guard protects more than just the enamel. Learn more about bruxism.
Tobacco use reduces blood flow to gum tissue and slows healing. Hormonal shifts during pregnancy or menopause make gums more reactive to inflammation. Crooked teeth put uneven stress on the surrounding gum. And lip or tongue piercings, if they sit against the gumline regularly, cause localized recession at that spot over time.
Usually it’s a combination. Usually addressing one thing helps, but it’s worth understanding the full picture.
Signs of Gum Recession — What to Look For
Longer-looking teeth are the most obvious sign, especially if you notice it gradually in photos over a few years. The exposed root surface is slightly darker and more yellow than the enamel above it — it has a different texture and colour that becomes more visible as the gumline drops.
You might also feel a notch at the base of a tooth when you run your tongue across it. That step, where smooth enamel transitions to the rougher root surface, is a reliable indicator.
Sensitivity is another one — but pay attention to where. Recession-related sensitivity is typically localized. One tooth, or a small group of teeth in the same area, reacts badly to cold or heat while the rest of the mouth feels fine. That pattern is meaningfully different from generalized sensitivity, which has other causes.
The honest caveat here is that early recession usually doesn’t hurt at all. There’s often nothing to prompt someone to get it checked. That’s exactly why it tends to be discovered at routine appointments rather than by patients on their own — we’re measuring, not relying on symptoms.

Can Gum Recession Be Reversed?
No. That’s the direct answer, and it’s worth being clear about it: gum tissue doesn’t grow back on its own. Once recession has happened, that tissue is gone without intervention (Cleveland Clinic, 2022).
What that doesn’t mean is that nothing can be done. It means the goal shifts — from reversing to stopping and restoring. In early stages, catching the cause and correcting it (better brushing technique, treating active gum disease, getting a night guard) can stop recession from progressing further. No surgery, no grafts. Just stabilization.
Moderate to severe recession — where there’s meaningful tissue loss — typically requires surgical treatment to restore what’s been lost. But that’s different from “nothing can be done.” Gum grafting works, and it works well.
Timing shapes the options. There’s a reason we keep saying to catch it early.
Gum Recession Treatment Options
Treatment depends on what caused the recession and how far it’s gone.
If active periodontal disease is involved, scaling and root planning comes first. This is a deeper cleaning than a standard hygiene appointment — done under local anesthetic, targeting the plaque and tartar buildup below the gumline that standard brushing and regular cleanings can’t reach. Removing that bacterial buildup lets the inflammation settle and stops the disease from driving further tissue loss.
For mild recession, dental bonding offers a non-surgical option. A tooth-coloured composite resin is applied over the exposed root surface, covering it and reducing sensitivity. It doesn’t restore the gum tissue, but it protects the area and improves how it looks. Desensitizing toothpastes — ones with potassium nitrate or stannous fluoride — can also help manage sensitivity in the meantime (Cleveland Clinic, 2022).
Gum graft surgery is the definitive treatment for more significant recession. The most common version is a connective tissue graft: a small piece of tissue from the roof of the mouth is surgically placed over the exposed root and stitched into position. Recovery is usually around two weeks (Cleveland Clinic, 2022). It sounds more involved than it is — patients are routinely surprised by how manageable the recovery is — and the results are predictable and long-lasting.
There’s also the Pinhole Surgical Technique, a newer minimally invasive approach where existing gum tissue is repositioned through a small opening rather than grafted. Not every clinic offers it, and it’s not suited to every case, but it’s worth asking about.
If misaligned teeth are part of what’s driving the recession, orthodontic treatment can be part of the solution — correcting tooth position distributes biting forces more evenly, which removes one source of stress on the surrounding tissue.

How to Prevent Gum Recession
The most impactful single change most patients can make is switching to a soft-bristle toothbrush. Not medium. Soft. Medium bristles feel more thorough; they’re not. They scrub at the gumline in ways soft bristles don’t. Replace the brush when the bristles start to splay — which, for people who brush too firmly, happens faster than the recommended three months.
Brush at an angle — around 45 degrees to the gumline — using short circular strokes rather than horizontal scrubbing. If the bristles are flattening against the tooth right away, you’re pressing too hard. The brush does the work; you’re just guiding it.
Floss daily. Not sometimes. The spaces between teeth are exactly where early gum disease takes hold, and brushing doesn’t reach them properly no matter how thorough you are.
Twice-yearly professional cleanings matter because tartar — hardened plaque — can’t be removed by brushing. Once it calcifies onto the tooth surface, only a dental instrument removes it. Patients with a history of gum disease often need cleanings every three to four months rather than every six; that frequency isn’t excessive, it’s maintenance.
Night grinding deserves its own paragraph. If you wake up with jaw soreness, headaches, or worn-down teeth, there’s a decent chance you grind at night without knowing it. A custom guard from your dentist protects both the enamel and the gum attachment from that nightly stress. It’s one of the better investments in gum health available.
Smoking makes all of this harder. The evidence on tobacco and periodontal disease is unambiguous — it reduces blood flow, impairs healing, and significantly raises the risk of gum disease driving recession. If you smoke, every other prevention step works less well than it should.
Conclusion
Gum recession is common, slow, and genuinely manageable — but only if it’s caught and addressed. Left alone, it doesn’t plateau on its own. It keeps going, and the options become more involved the further along it gets.
The frustrating part is that it rarely announces itself clearly. That’s why routine checkups catch it more reliably than self-monitoring. A dentist can see and measure changes you won’t notice in a mirror until they’re significant.

No — receded tissue doesn’t regrow on its own. But it can be halted and, where the loss is significant, surgically restored through grafting. The earlier it’s caught, the less invasive the response needs to be.
Teeth appear longer than they used to, and the base of the tooth looks different — slightly darker, more yellow, different texture than enamel. You might also feel a notch or ridge at the gumline with your tongue. Not everyone notices visually until it’s fairly advanced, which is part of the problem.
It depends on the cause. Disease-driven recession can move faster than expected; brushing-related recession is slower but cumulative. Either way, it doesn’t stabilize on its own without addressing what’s driving it.
Yes, in many cases. Improving home care, treating underlying gum disease, correcting brushing technique, and using desensitizing products can stop early recession from progressing. Surgery becomes the conversation when there’s meaningful tissue loss that other approaches can’t adequately address.
Severe, untreated recession — especially when tied to active periodontal disease — can eventually compromise bone support enough to cause a tooth to become mobile. It’s not a quick process, but it’s a real outcome of prolonged neglect. Treatment at any stage prevents things from getting to that point.
Most people feel back to normal within two weeks (Cleveland Clinic, 2022). The specifics depend on how many teeth were treated and what type of graft was done. Your dentist or periodontist will give you detailed aftercare instructions, and most patients find the recovery more manageable than they expected.
