Gum recession is common, usually gradual, and permanent once it has happened, but further loss can almost always be stopped. Recession means the gum margin has moved away from the crown of the tooth, exposing root surface that has no protective enamel. It is not an emergency, yet it should never be ignored, because exposed roots decay faster and are far more sensitive. Modern options including laser dental treatment allow inflamed tissue to be treated precisely and comfortably.
Around half of adults show some measurable recession, and the proportion rises steadily with age. In most cases the cause is a combination of gum inflammation and mechanical trauma rather than a single factor.
Accurate measurement is the starting point. A full periodontal assessment at Celina Dentistry records where the gum sits on every tooth so change can be tracked objectively.
Exposed roots often need protecting as well as monitoring. Bonded restorations delivered as part of a restorative dentistry plan seal sensitive areas and prevent root decay.
Recession also changes how cosmetic treatment is planned. Where roots are exposed, teeth whitening needs modified gel strength and protective barriers to avoid discomfort.
Where advanced recession has already led to tooth loss, replacement becomes part of the conversation, and dental implants require healthy, stable gum tissue to succeed.
If your teeth look longer than they used to or cold water makes you wince, book an assessment so the cause can be identified before more tissue is lost.
What Is Gum Recession?
The gum, or gingiva, normally sits just above the point where the enamel crown meets the root. Recession is the apical migration of that margin, meaning it moves down on upper teeth and up on lower teeth, exposing cementum and dentine.
Root surface differs from enamel in three important ways. It is softer, it decays significantly faster, and it contains open dentinal tubules that transmit temperature and sweetness directly toward the nerve.
Recession Versus Gum Disease
The two overlap but are not identical. Periodontitis destroys bone and attachment, and recession often follows. However, recession can also occur with perfectly healthy bone, for example from years of aggressive brushing or from a naturally thin gum type. Distinguishing the two determines the treatment entirely.
What Causes Gum Recession?
Periodontal Disease
Plaque and tartar below the gum line cause chronic inflammation that destroys the attachment and supporting bone. This is the most significant cause because it also involves bone loss.
Aggressive Brushing
Hard bristles, heavy pressure and a scrubbing horizontal motion physically abrade the gum margin. The classic sign is recession on the outer surfaces of canines and premolars, often with a notch worn into the tooth.
Thin Gum and Bone Anatomy
Some people naturally have a thin biotype with less bone covering the root. These patients are more prone to recession even with excellent hygiene.
Grinding and Bite Overload
Excessive occlusal force does not cause recession alone, but it accelerates loss where inflammation is already present and contributes to notching at the gum line.
Tooth Position
Teeth that sit outside the arch or are crowded have thinner bone covering, making them vulnerable.
Orthodontic Movement
Rapid or excessive movement of a tooth through thin bone can result in recession, which is why controlled forces and periodontal monitoring matter during treatment.
Smoking and Vaping
Nicotine reduces gum blood flow, impairs healing and masks bleeding, so disease often progresses further before it is noticed.
Other Contributors
- Oral piercings rubbing against the gum
- Poorly fitting partial denture clasps
- Hormonal changes affecting tissue response
- Habitual picking at the gums with fingernails or objects
Warning Signs
- Teeth that appear longer than they used to
- A visible step or notch where the crown meets the root
- Sensitivity to cold air, cold water or sweet foods
- A yellowish band near the gum line, since root is darker than enamel
- Fillings that suddenly look exposed at their edge
- Food catching in newly opened spaces between teeth
- Gums that bleed, look red or feel tender
- Any tooth that feels slightly mobile
Loose teeth, pus, localised swelling or rapid change over a few months require prompt assessment. Sudden localised recession with a deep isolated pocket can also indicate a cracked root rather than gum disease.
How Recession Is Assessed
- History. Brushing technique and brush type, smoking, grinding, orthodontic history and any medical conditions.
- Measurement. Recession is recorded in millimetres from a fixed reference point on each affected tooth.
- Pocket charting. Depths and bleeding points establish whether active periodontal disease is present.
- Biotype assessment. Gum thickness is evaluated, since thin tissue responds differently to treatment.
- Radiographs. Bone levels distinguish recession with intact bone from recession caused by bone loss.
- Sensitivity testing. Exposed root areas are identified for targeted treatment.
- Photographs. Images give an objective baseline for comparison at review.
Periodontal diagnosis should always be carried out by a licensed dental professional, because interpreting probing depths and radiographs correctly is what separates stable recession from progressive disease.
Treatment Options
Non Surgical Management
- Professional scaling and root surface debridement to remove tartar and pocket biofilm
- Personalised brushing coaching, including switching to a soft brush and a gentle rolling technique
- Desensitising agents, fluoride varnish and prescription strength fluoride toothpaste
- Bonded composite to cover exposed root surfaces and worn notches
- A nightguard where grinding is contributing
- Correction of irritants such as a rough denture clasp
- Shortened recall intervals with photographic monitoring
For the majority of patients this combination stops progression and resolves sensitivity without any surgery.
Laser Assisted Treatment
Dental lasers are used to decontaminate periodontal pockets, remove inflamed tissue precisely and reshape gum contour with minimal bleeding. Advantages reported include reduced discomfort, less need for sutures and faster soft tissue healing. It is important to be balanced here. Laser therapy is a valuable adjunct to thorough mechanical cleaning rather than a replacement for it, and it does not regenerate lost gum tissue by itself.
Surgical Options
- Connective tissue graft. Tissue taken from the palate is placed over the exposed root, the most established technique for coverage.
- Free gingival graft. Used to thicken thin tissue rather than primarily to cover root.
- Pinhole and tunnel techniques. Minimally invasive approaches that reposition existing tissue coronally.
- Guided tissue regeneration. Used where bone loss accompanies the recession.
Grafting is considered when sensitivity persists despite conservative care, when recession continues to progress, when root decay risk is high, or when appearance is significantly affected. Success depends on stable gum health and, critically, on eliminating the original cause first.
Treatment Approaches Compared
| Approach | What it achieves | What it cannot do |
|---|---|---|
| Improved brushing technique | Stops mechanical progression | Restore lost tissue |
| Scaling and root debridement | Controls inflammation and pocket depth | Regrow bone |
| Laser therapy | Decontaminates pockets, reshapes tissue, aids healing | Replace thorough mechanical cleaning |
| Composite bonding | Seals sensitive root and worn notches | Change gum position |
| Gum grafting | Covers root and thickens tissue | Succeed if the cause continues |
Myths About Gum Recession
Myth: recession is just part of getting older. It becomes more common with age because causes accumulate, but healthy gums do not recede simply through the passage of time.
Myth: gums grow back. Gum tissue does not spontaneously regenerate over an exposed root. Only grafting can achieve coverage.
Myth: brushing harder helps receding gums. Pressure is one of the main causes. Technique matters far more than force.
Myth: bleeding means you should stop cleaning that area. The opposite is true. Bleeding indicates inflammation from plaque, and gentle consistent cleaning resolves it.
Myth: treatment for gum problems is unbearable. Root debridement is performed under local anaesthetic, and laser assisted care often reduces post treatment discomfort further. Anxiety is common and is managed rather than dismissed.
Prevention That Works
- Use a soft brush with light pressure, or an electric brush with a pressure sensor
- Brush in small circular or rolling motions rather than scrubbing sideways
- Clean between every tooth daily with floss or correctly sized interdental brushes
- Replace your brush every three months, or sooner if bristles splay
- Avoid abrasive charcoal and heavy whitening pastes
- Treat grinding with a custom nightguard
- Stop smoking and vaping, which is the single most impactful change for gum health
- Attend hygiene appointments at the interval set for your individual risk
- Have any oral piercing assessed if it contacts gum tissue
Patient Scenarios
The Meticulous Brusher
A patient in their thirties brushes three times daily with a firm brush and reports cold sensitivity on the upper canines. Bone levels are normal and there is no periodontal disease. The cause is mechanical. Switching to a soft brush with light pressure plus composite bonding over the notches resolves the sensitivity and halts progression.
Long Standing Periodontitis
A patient in their sixties has generalised recession, deep pockets and radiographic bone loss. Grafting is not the first step. Non surgical gum therapy with laser adjunct, followed by three monthly maintenance, stabilises the situation before any surgical option is considered.
A Single Recessed Front Tooth
An upper canine sits outside the arch and shows isolated recession affecting appearance. Once hygiene is stable, a connective tissue graft provides coverage, with orthodontic assessment considered to reduce future risk.
Sudden Localised Change
A patient develops recession and a deep isolated pocket on one molar within months. Imaging reveals a vertical root fracture rather than gum disease, and the treatment path is entirely different.

Frequently Asked Questions
Can receding gums grow back naturally?
No. Gum tissue does not regenerate over an exposed root on its own, and no toothpaste or mouthwash can restore it. What can be achieved is stopping further recession, sealing exposed root surfaces to remove sensitivity, and where appropriate, surgically covering the root with a graft.
Is gum recession always caused by gum disease?
Not always. Periodontal disease is the most serious cause because it involves bone loss, but recession also occurs from aggressive brushing, thin natural gum anatomy, tooth position, grinding and orthodontic movement in patients with perfectly healthy bone. Radiographs and pocket charting distinguish between these.
Why are my teeth so sensitive where the gum has receded?
Root surface has no enamel and contains microscopic dentinal tubules that connect toward the nerve. Cold, sweetness and air movement stimulate fluid within those tubules, which the nerve interprets as a sharp sensation. Sealing the surface with bonding or applying desensitising agents blocks that pathway effectively.
Does laser treatment cure gum recession?
Laser therapy does not restore lost gum tissue. What it does well is decontaminate periodontal pockets, remove inflamed tissue precisely and reshape gum contour with minimal bleeding and faster healing. It works best as an adjunct to thorough mechanical cleaning and improved home care, not as a standalone cure.
Will I lose the tooth if my gums keep receding?
Not necessarily. Recession with healthy underlying bone rarely leads to tooth loss once the cause is corrected. Recession accompanied by significant bone loss carries more risk, but well managed periodontal disease can remain stable for decades with regular maintenance and good daily cleaning.
Conclusion
Gum recession cannot be reversed on its own, but its progression can be stopped in almost every case once the cause is identified. Gentle brushing, professional cleaning and sealing exposed roots resolve sensitivity and protect against root decay. Regular measurement is what turns an unpredictable problem into a managed one.
