Why Are My Gums Receding? Common Causes and When Periodontal Care Is Needed

Have you noticed that your teeth seem longer than they used to, or that the gumline around certain teeth is gradually moving downward? You may be experiencing gum recession. Receding gums are common, but they should not be ignored. Once gum tissue has pulled away from a tooth, the exposed root can become sensitive, harder to keep clean, and more vulnerable to decay.

At Clarkson Smiles, we help patients in Clarkson and Mississauga understand what is causing changes in their gumline and whether periodontal care is needed. Gum recession can have several causes, and identifying the reason is important for protecting your teeth and preventing further damage.

What Is Gum Recession?

Gum recession occurs when the gum tissue surrounding a tooth moves away from its normal position and exposes more of the tooth or its root.

Healthy gums fit closely around the teeth and provide protection for the sensitive root surfaces underneath. When gums recede, those roots become exposed. Since tooth roots do not have the same protective enamel covering as the crowns of your teeth, they can become sensitive to temperature, brushing, and certain foods.

Recession can affect one tooth, several teeth, or larger areas of the mouth. It may develop gradually, which means many people do not notice it until the change becomes more obvious.

Gum Disease Can Cause Recession

One of the most important causes of gum recession is periodontal disease.

Gum disease begins when plaque and bacteria accumulate around the gumline. Early inflammation, known as gingivitis, may cause redness, swelling, and bleeding when brushing or flossing. If it progresses, bacteria can move deeper beneath the gums and begin damaging the tissues and bone that support the teeth.

As this support is lost, the gums may pull away from the teeth and periodontal pockets can develop.

Professional periodontal care in Mississauga can help identify the severity of gum disease and determine whether treatments such as scaling and root planing or ongoing periodontal maintenance are appropriate.

Brushing Too Hard Can Damage the Gumline

Many people assume that brushing harder means cleaning better. In reality, aggressive brushing can irritate the gums and contribute to recession over time.

Using a hard-bristled toothbrush, applying too much pressure, or scrubbing back and forth can gradually wear away gum tissue and tooth structure near the gumline.

A soft-bristled toothbrush and gentle technique are usually more effective and safer. Position the brush at the gumline and use small, controlled movements rather than forceful scrubbing.

During routine general and preventive dentistry visits, your dental team can identify areas where brushing habits may be affecting your gums and recommend techniques that clean effectively without causing unnecessary damage.

Teeth Grinding Can Put Stress on the Gums

Grinding and clenching, also known as bruxism, can place significant pressure on teeth and their supporting structures.

Repeated forces may contribute to tooth wear, small fractures, sensitivity, and changes around the gumline. If certain teeth absorb more pressure than others, recession may become more noticeable in those areas.

Signs of grinding can include flattened or worn teeth, chipped restorations, morning jaw discomfort, headaches, or sensitivity.

If bruxism is contributing to dental damage, a custom bruxism appliance may be recommended to help protect your teeth while you sleep.

Tooth Position Can Affect Gum Health

Teeth that are crowded, rotated, or positioned outside the ideal arch may have thinner gum and bone coverage.

When the gum tissue around a tooth is naturally thin, it can be more susceptible to recession. In some cases, improving tooth alignment may help create a healthier relationship between the teeth, gums, and bite.

For appropriate cases, Invisalign may be used to gradually improve tooth alignment. Orthodontic treatment should always be planned carefully when recession is already present, since gum health needs to be considered throughout treatment.

Aging Can Make Recession More Noticeable

Gum recession becomes more common with age, partly because teeth and gums have been exposed to decades of brushing, chewing, plaque, dental treatments, and other stresses.

This does not mean recession should simply be accepted as a normal part of getting older. Older adults can still benefit from periodontal evaluation, professional cleaning, and personalized home care recommendations.

Clarkson Smiles provides dentistry for seniors with attention to changing gum health, existing restorations, dry mouth, tooth wear, and other age-related oral health concerns.

Why Receding Gums Can Cause Sensitivity

When the root of a tooth becomes exposed, sensitivity is common.

You may feel a sharp sensation when drinking cold water, eating something sweet, or brushing near the gumline. Because root surfaces are less protected than enamel, temperature and pressure can reach the sensitive inner structures of the tooth more easily.

Sensitivity does not always mean you have gum recession, however. Cavities, cracks, worn fillings, or other conditions can cause similar symptoms. A dental examination can determine the source.

Recession Can Increase the Risk of Root Cavities

Exposed root surfaces are more vulnerable to decay.

Plaque can accumulate where the gumline has moved away from the tooth, and cleaning these areas can become difficult if they are sensitive. Because root surfaces are softer than enamel, cavities can develop more quickly.

If a small cavity develops, a tooth-coloured filling may be used to restore the damaged area. Preventing decay through regular cleaning and fluoride exposure is preferable whenever possible.

When Should You Seek Periodontal Care?

You should have your gums evaluated if you notice that your teeth look longer, the gumline is becoming uneven, or root surfaces are visible.

Other warning signs include bleeding while brushing or flossing, swollen gums, persistent bad breath, sensitivity, loose teeth, or spaces developing between teeth.

Your dentist may measure the pockets around your teeth to determine whether periodontal disease is present. X-rays may also be used to evaluate the bone supporting your teeth.

The treatment recommended depends on the cause and severity of the recession. If gum disease is responsible, controlling the infection is usually the first priority. In other cases, changes to brushing technique, management of grinding, or additional periodontal treatment may be appropriate.

Can Receding Gums Grow Back?

Gum tissue that has significantly receded generally does not grow back to its original position on its own.

However, that does not mean nothing can be done. Treatment can help stop or slow further recession, reduce inflammation, manage sensitivity, and protect exposed root surfaces.

In more advanced situations, gum grafting or other periodontal procedures may be considered to restore tissue coverage. The best approach depends on the reason for the recession and the health of the surrounding teeth and bone.

FAQ

Why are my gums suddenly receding?

Gum recession can be caused by periodontal disease, aggressive brushing, teeth grinding, tooth position, trauma, or naturally thin gum tissue. An examination can help determine why the change is occurring.

Can brushing too hard cause receding gums?

Yes. Using excessive pressure or a hard-bristled toothbrush can gradually damage gum tissue. A soft-bristled brush and gentle technique are usually recommended.

Will receding gums grow back naturally?

Significantly receded gum tissue generally does not grow back on its own. However, treatment can help prevent further recession and protect exposed tooth roots.

Are receding gums always caused by gum disease?

No. Gum disease is an important cause, but recession can also result from brushing habits, grinding, tooth alignment, thin gum tissue, or other factors.

When should I see a dentist about receding gums?

Schedule an appointment if you notice exposed roots, increasing sensitivity, bleeding gums, persistent bad breath, loose teeth, or visible changes in your gumline. Early assessment can help identify the cause and prevent further damage.
