Why Are My Gums Swollen or Receding?

Swollen Gums Are Often a Sign of Irritation

Swollen gums can happen for many reasons, but they often point to irritation or inflammation around the gumline. This may be caused by plaque buildup, food trapped between the teeth, brushing too aggressively, hormonal changes, certain medications, or an infection. When gums feel tender, look puffy, or bleed when you brush or floss, it is a sign that your mouth needs attention.
 

At SmileOn Dentistry, we look at the whole picture - your gums, teeth, bite, oral hygiene habits, and any symptoms you are experiencing - so we can help identify what is causing the swelling.
 

Gum Recession Can Happen Gradually

Receding gums occur when the gum tissue pulls away from the teeth, exposing more of the tooth or root surface. This can make teeth look longer and may lead to sensitivity, especially with cold drinks or brushing.
 

Gum recession can develop slowly, which is why many patients do not notice it right away. Common causes include gum disease, brushing too hard, teeth grinding, genetics, tobacco use, and past orthodontic movement. Even if recession does not hurt, it should be evaluated because exposed roots are more vulnerable to sensitivity and decay.
 

Plaque and Gum Disease Are Common Causes

One of the most common reasons for swollen or receding gums is plaque buildup. Plaque contains bacteria that can irritate the gums and lead to gingivitis, the earliest stage of gum disease. Gingivitis is often reversible with professional care and improved home hygiene.
 

If gum inflammation is not treated, it can progress into periodontal disease. At that stage, the gums and supporting bone may begin to pull away from the teeth. This can cause pockets, gum recession, loose teeth, and ongoing inflammation.
 

Symptoms You Should Not Ignore

Some gum changes may seem minor at first, but they can be early signs of a bigger oral health issue. We recommend scheduling an exam if you notice:

• Swollen, red, or tender gums
• Bleeding when brushing or flossing
• Gum recession or teeth looking longer
• Persistent bad breath
• Tooth sensitivity near the gumline
• Loose teeth or changes in your bite
• Pus, sores, or a bad taste in your mouth

These symptoms do not always mean you have advanced gum disease, but they do mean your gums should be checked by a dental professional.
 

How We Evaluate Gum Health

During your visit, we examine your gums closely and measure the spaces between your teeth and gum tissue. These measurements help us check for inflammation, recession, and periodontal pockets. We may also take digital X-rays to look at the bone supporting your teeth.
 

Our goal is to find the cause of the problem before it gets worse. Whether you need a routine cleaning, a deeper periodontal cleaning, oral hygiene guidance, or follow-up care, we tailor treatment to your needs.
 

Healthy Gums Support a Healthy Smile

Your gums are the foundation of your smile. When they are inflamed or receding, your teeth may become more sensitive, harder to clean, and more vulnerable to long-term issues. The earlier we address gum concerns, the easier it is to protect your comfort, oral health, and confidence.
