Receding Gums: Causes, Treatment, Cost, and How to Stop Them

Editorially reviewed by the Dental.me Editorial Team · Updated July 2026

Receding gums happen when gum tissue pulls back from your teeth and exposes the root, and once that tissue is gone it does not grow back on its own. You cannot reverse recession at home. But in nearly every case, you can stop it from getting worse. The two biggest culprits are aggressive brushing and gum disease, and both are fixable once you figure out which one you’re dealing with.

That distinction matters more than most people think. Recession from scrubbing too hard with a stiff brush is a mechanical problem, plain and simple. Recession from periodontal disease is an infection quietly eating the bone underneath. In the mirror they can look identical, but the treatment paths have nothing in common, and mixing them up costs you months.

What do receding gums look like?

The first thing most people notice is that a tooth suddenly looks longer than it used to. That’s where the phrase “long in the tooth” comes from. What you’re actually seeing is exposed root surface, which is darker and a touch yellower than the enamel crown above it.

Common signs, roughly in the order they tend to show up:

• Sensitivity to cold, sweet, or air. The root has no enamel to shield it, so the nerve reacts fast. That sharp zing when you sip iced water is the classic early warning.
• A visible notch or step where the crown meets the root, sometimes with a little ledge you can catch with a fingernail.
• Teeth that look uneven in length next to the ones beside them.
• Gums that look red, puffy, or bleed when you brush or floss. That points to recession driven by disease, not just mechanics.
• A loose feeling in one or more teeth in advanced cases, which means you’ve already lost bone.

Recession creeps. It moves a fraction of a millimeter at a time, so most people don’t catch it until a tooth is visibly longer or a cold drink makes them flinch.

What causes receding gums?

There’s rarely one clean cause. Most recession is a stack of factors piling onto the same tooth over years. Here’s how the main drivers usually break down.

Brushing too hard

This is the one people get most wrong. Hard bristles, a heavy hand, and a back-and-forth sawing motion physically scrub the gum line away. The cruel irony: the most diligent brushers often have the worst recession, because they’ve decided that pressure equals clean. A firm toothbrush does not clean better. It just does more damage.

Gum disease (periodontitis)

Bacteria in plaque inflame the gums (gingivitis), and left alone that can progress to periodontitis, where the infection destroys the bone and connective tissue holding your teeth in place. As the support structure dissolves, the gum line follows it down. This is the serious one, because the same disease that recedes your gums can eventually loosen and lose them.

Grinding and clenching (bruxism)

Clenching and grinding load your teeth sideways. That flexing stress concentrates right at the gum line and can crack the thin outer enamel there, feeding the recession and those little notches near the root. Plenty of grinders do it in their sleep and have no clue they’re doing it.

Genetics and thin gum tissue

Some people are simply born with thin, delicate gum tissue (a “thin biotype”) that gives way more easily. Tooth position plays a part too. A tooth that sits slightly outside the arch has less bone in front of it and is more prone to recession no matter how gently you treat it.

Tobacco, piercings, and orthodontics

Smoking and vaping starve the gums of blood flow, which makes periodontal disease worse and much harder to treat. A metal stud from a lip or tongue piercing rubs one spot raw over time. And braces or aligners that move teeth too fast can outrun the bone, especially on lower front teeth.

Can receding gums grow back or be reversed?

No. That’s the honest answer a lot of the internet tiptoes around. Once gum tissue has receded, it does not regenerate on its own, and no toothpaste, oil pull, mouthwash, or supplement rebuilds it. Any product promising to “regrow” your gums is selling you hope in a tube.

Here’s the useful part, though. The goal was never regrowth. The goal is to stop the recession where it is and manage the symptoms. Most people can freeze the progression completely by fixing the cause. And when an exposed root genuinely needs covering, for sensitivity, appearance, or to protect the tooth, a periodontist can surgically restore the gum line with a graft. That’s the only real “reversal,” and it’s a procedure, not a product.

How are receding gums treated?

Treatment ladders up from simple and cheap to surgical, depending on how far the recession has gone and what’s driving it. A good dentist treats the cause first. Grafting a tooth while you keep scrubbing it, or while active disease keeps chewing through bone, is money down the drain.

Deep cleaning and grafting are jobs for someone who lives in gums all day. If disease or root coverage is on the table, you want a periodontist, the dental specialty that handles exactly this. For sensitivity, notches, and prevention, a general dentist is the right first stop.

How do you stop receding gums from getting worse?

Prevention is where you hold the most leverage, and it genuinely works. The recession you already have won’t grow back, but you can keep it from advancing another millimeter.

1. Switch to a soft or extra-soft toothbrush. Not medium. Soft. If your bristles splay out after a month, you’re leaning on it too hard.
2. Brush gently, in small circles, not a hard side-to-side saw. Angle the brush at 45 degrees toward the gum line. An electric brush with a pressure sensor takes the guesswork out of it.
3. Floss daily. Disease-driven recession starts between the teeth, exactly where the brush never reaches.
4. See a dentist or hygienist regularly. Professional cleanings clear the hardened tartar you can’t brush off, and early gum disease is silent. It rarely hurts until it’s advanced.
5. Wear a night guard if you grind. If you wake with a sore jaw or your dentist points out wear facets, this one’s probably you.
6. Stop smoking and vaping. Nothing improves gum outcomes faster, and nothing sabotages them more reliably.

The through-line is simple. Recession is usually the payoff of a habit or an infection that’s been running for years. Interrupt it, and the damage stops. Ignore it, and it keeps going until the root, or the whole tooth, is at risk.

When should you see a dentist for receding gums?

Don’t wait for pain. Book a visit if a tooth suddenly looks longer, if cold or sweet triggers a sharp jolt, if your gums bleed when you brush, or if you can see or feel a notch at the gum line. Bleeding gums especially are not normal, and they’re the earliest sign that disease-driven recession may already be underway. Catch it at gingivitis and it’s a cleaning. Catch it at advanced periodontitis and it’s surgery. The gap between those two is measured in dollars and teeth.

Frequently asked questions

Do receding gums grow back?

No. Lost gum tissue does not regenerate on its own, and no toothpaste or home remedy regrows it. You can stop recession from getting worse by fixing the cause, and a periodontist can surgically cover an exposed root with a gum graft, but the tissue does not come back by itself.

Is a little gum recession normal with age?

Some recession is common as people get older, which is where “long in the tooth” comes from. But age alone is not the cause. It’s decades of brushing habits, grinding, and gum health adding up. Recession is not inevitable, and it should never be waved off as “just aging” if your gums are bleeding or a tooth feels loose.

Does a gum graft hurt, and is it worth it?

Modern grafts are done under local anesthesia, and most people describe the recovery as sore rather than painful, easing within a week or two. It’s worth it when recession causes ongoing sensitivity, threatens the tooth, or bothers you cosmetically. For mild cases, gentler brushing and desensitizing treatment often solve the problem without surgery.

Can whitening or hard brushing cause receding gums?

Hard brushing is one of the leading causes. A firm brush and heavy pressure physically wear the gum line away. Whitening does not cause recession, but it can make already-exposed roots temporarily more sensitive, because the root has no protective enamel.

How much does it cost to fix receding gums?

It depends entirely on the cause and severity. A brushing-technique fix costs nothing, a deep cleaning for gum disease runs a few hundred dollars per quadrant, and a gum graft is typically $600 to $1,200 or more per tooth in the US. Dental insurance often covers part of periodontal treatment. These are typical ranges, not a quote. Only an in-person exam gives an accurate price.

What is the difference between a general dentist and a periodontist for this?

A general dentist handles prevention, desensitizing, bonding, and catching gum disease early. A periodontist is the gum specialist who performs deep cleanings for established disease and surgical grafts to cover exposed roots. Serious or advancing recession is a periodontist’s territory.
