What causes receding gums, and how are they treated?
Receding gums happen when the gumline moves away from the tooth and exposes more tooth or root surface. The cause may be plaque, tartar, gum inflammation, brushing pressure, tooth position, clenching, injury, tobacco use, dry mouth, thin tissue, or several factors together.
Gum recession is not something to diagnose from a mirror alone. A tooth can look longer because tissue has moved, because inflammation has changed, because the bite is stressing the area, or because an older dental margin is more visible. The useful question is what is causing the change and whether it is stable.
If your gums also bleed or feel swollen, start with our guide to the early signs of gum disease and our preventive dentistry page.
What are receding gums?
Gum recession means the edge of the gum tissue has shifted away from its normal position around the tooth. The tooth may look longer, the gumline may look uneven, or the exposed area near the root may feel sensitive.
The root surface is different from enamel. It can be more sensitive to cold, air, brushing, sweets, or dental cleanings. It can also be more vulnerable when plaque sits along the exposed area. That is why recession is not only a cosmetic issue; it can affect comfort, cleanability, and long-term tooth protection.
Recession can affect one tooth or several teeth. It can move slowly enough that a patient notices only after comparing old photos, feeling a notch near the gumline, or realizing that one area catches food or feels cold-sensitive.
What are the most common causes of receding gums?
Plaque, tartar, and gum inflammation
Plaque collects around the teeth and gumline every day. If it is not disrupted well, it can irritate the gum tissue. Over time, plaque can harden into tartar, which cannot be brushed or flossed away at home.
When inflammation continues, the gum tissue may bleed, swell, pull away from the tooth, or form deeper spaces around the tooth. That can make the area harder to clean, which lets more plaque and tartar collect. Recession that appears with bleeding, swelling, persistent bad breath, pus, loose teeth, or bite changes should be checked promptly.
Our article on what to expect during a deep cleaning explains how scaling and root planing may fit when deposits and inflammation extend below the gumline.
Brushing too hard
Aggressive brushing can damage the gum margin, especially with a hard-bristled brush or a forceful side-to-side scrubbing motion. More pressure does not mean cleaner teeth. It can wear tooth structure near the gumline and irritate thin gum tissue.
A soft-bristled toothbrush, lighter pressure, and controlled technique are usually safer. If you use an electric toothbrush, pay attention to pressure alerts rather than trying to overpower the brush.
Tooth position, crowding, and bite pressure
A tooth that sits outside the ideal arch, is rotated, is crowded, or carries uneven bite pressure may have less protective tissue on one side. Clenching and grinding can also stress teeth and restorations. Recession does not prove that the bite is the only cause, but tooth position and bite forces are part of a careful exam.
This is one reason we do not treat every recession case the same way. The same visible gumline change can have different causes in different mouths.
Injury, appliances, and repeated rubbing
Trauma can injure gum tissue. So can repeated rubbing from an oral appliance, a rough edge, a piercing, or a habit that keeps irritating the same area. If the source of irritation continues, the tissue may keep responding.
Tell us if a night guard, retainer, partial denture, orthodontic appliance, or restoration feels like it rubs the gumline. Small fit details can matter when the same spot is irritated every day.
Tobacco use, dry mouth, and medical factors
Tobacco use can make gum problems harder to control and healing less predictable. Dry mouth can also raise risk because saliva helps protect the teeth and soft tissues. Diabetes, immune concerns, some medications, and a history of gum disease can affect how gums respond to plaque and treatment.
Those details do not mean a patient caused the recession. They help us choose a more accurate plan and watch the right risk factors.
Naturally thin gum tissue
Some patients have thin gum tissue by anatomy. Thin tissue can be more vulnerable to recession from brushing pressure, tooth position, inflammation, or dental work near the gumline. Good home care still matters, but the plan may focus more on gentle technique, monitoring, and protecting exposed areas.
What symptoms can come with receding gums?
Visible recession is only one clue. Other signs may include:
- Tooth sensitivity to cold, air, sweets, brushing, or dental cleanings.
- A tooth that looks longer than nearby teeth.
- An uneven gumline.
- A notch, groove, or darker root surface near the gumline.
- Bleeding during brushing or flossing.
- Red, swollen, shiny, or tender gum tissue.
- Persistent bad breath or a bad taste near one area.
- Food catching near the gumline.
- A tooth that feels loose or a bite that feels different.
Sensitivity alone does not prove recession is the cause. Cavities, cracks, whitening sensitivity, worn enamel, clenching, and older restorations can feel similar. Our guide to why teeth are sensitive explains why the pattern matters.
How do we diagnose the cause of gum recession?
We start by looking at the gum tissue, tooth surfaces, bite, brushing pattern, symptoms, and health history. The exam may include gum measurements, checking for bleeding, evaluating recession, looking for tartar, testing sensitivity, checking tooth mobility, and reviewing digital X-rays when imaging is needed.
The goal is to separate active gum inflammation from mechanical irritation, bite stress, decay, cracks, recession from thin tissue, or a restoration problem. That distinction matters because treating sensitivity without addressing tartar, or treating tartar without changing damaging brushing pressure, misses the point.
Bring the details that help: when you first noticed the change, whether it is spreading, what triggers sensitivity, whether the area bleeds, whether you clench or grind, what toothbrush you use, and whether any appliance rubs the spot.
How are receding gums treated?
Treatment depends on the cause, severity, symptoms, and whether the recession is stable. The plan may be simple, or it may require monitoring over time.
Improve home care without scrubbing harder
Gentle daily plaque control is the baseline. Brush with a soft-bristled toothbrush, clean between the teeth daily, and avoid aggressive pressure at the gumline. If bleeding continues after consistent gentle care, do not assume you just need to brush harder. Persistent bleeding needs an exam.
Patients who want a stronger prevention routine can read our guide to everyday habits to prevent cavities, since many of the same habits protect the gumline.
Remove plaque and tartar professionally
If tartar or gum inflammation is part of the problem, professional cleaning is important. A routine cleaning may be appropriate when the gums are generally healthy or stable. Scaling and root planing may be discussed when periodontal pockets or deposits below the gumline need closer attention.
The right interval for cleanings depends on risk, history, home-care access, and what the exam shows. Our guide to how often you should get a dental cleaning explains why timing should be individualized.
Reduce sensitivity and protect exposed roots
If exposed root surfaces are sensitive, a desensitizing toothpaste, careful brushing technique, fluoride, or in-office sensitivity treatment may help. If the exposed area has decay, wear, or a shape that traps plaque, a tooth-colored restoration may be considered to protect the tooth structure.
That does not regrow gum tissue. It can make the area more comfortable and easier to maintain when restoration is appropriate.
Address bite stress, appliances, or tooth position
If clenching, grinding, a rough edge, or an appliance is irritating the area, the source of stress has to be addressed. In some cases, tooth position or crowding may be part of the conversation. The recommendation should come from an exam, not from the recession alone.
Discuss periodontal options when tissue loss is advanced
When recession is more advanced, keeps progressing, creates persistent sensitivity, affects cleanability, or leaves a root at higher risk, periodontal treatment options may be discussed. Gum grafting is one possible treatment in selected cases, but it is not the answer for every recession pattern and it does not replace control of plaque, bite stress, brushing trauma, or tobacco exposure.
Can receding gums grow back?
Lost gum tissue usually does not simply grow back to its old position on its own. That is why early evaluation matters. Treatment often focuses on stopping progression, improving cleanability, reducing sensitivity, protecting exposed root surfaces, and deciding whether periodontal treatment should be considered.
A stable area with mild recession may need monitoring and better technique. A painful, worsening, hard-to-clean, or inflamed area deserves a more active plan.
When should you call about receding gums?
Call for an exam if recession is new, worsening, painful, sensitive, or uneven; if gums bleed repeatedly; if bad breath or a bad taste persists; if food catches around the gumline; or if a tooth feels loose.
Call sooner if recession appears with swelling, pus, severe pain, fever, facial swelling, or pain when biting. If swelling affects breathing or swallowing, that is beyond routine dental scheduling and needs emergency medical care.

FAQ: what causes receding gums
Are receding gums always caused by brushing too hard?
No. Aggressive brushing can contribute, but gum inflammation, tartar, tooth position, clenching, injury, tobacco use, dry mouth, thin tissue, and medical factors can also be involved.
Does gum recession mean I have gum disease?
Not always. Recession can happen without active gum disease, but gum disease is a major possible cause. Bleeding, swelling, deeper pockets, bad breath, loose teeth, or bone changes make an exam especially important.
Can a deep cleaning fix receding gums?
Scaling and root planing can help control deposits and inflammation below the gumline when periodontal disease is involved. It may help prevent further damage, but it does not automatically replace tissue that has already been lost.
What toothpaste is best for receding gums?
A fluoride toothpaste can help protect teeth, and a desensitizing toothpaste may reduce exposed-root sensitivity. Toothpaste cannot diagnose the cause or regrow gum tissue, so persistent symptoms should be checked.
When is gum recession urgent?
Recession should be checked promptly when it is worsening, painful, bleeding, swollen, or paired with loose teeth, pus, fever, facial swelling, or pain when biting. Breathing or swallowing trouble needs emergency medical care.
Can receding gums cause tooth loss?
Advanced gum disease can damage the tissues and bone that support teeth, which can contribute to looseness and tooth loss. Early diagnosis, plaque control, professional care, and monitoring help protect the teeth.
