A severely decayed molar accompanied by swelling along the inner cheek side of the gum may indicate an underlying dental infection. When bacteria penetrate deep into a tooth, they can reach the dental pulp—the soft tissue containing nerves and blood vessels—and potentially spread into the tissues surrounding the tooth root.
A small, red bump or swollen area above the upper front teeth may look harmless, but it can sometimes indicate a localized dental infection. Patients may notice tenderness when touching the gum, discomfort while brushing, a bad taste in the mouth, or a small pimple-like swelling that releases pus.
The image shows localized gum swelling and redness above the upper front teeth, visible when the upper lip is lifted. The teeth themselves appear generally intact and aligned, but the gum tissue above them looks inflamed and slightly raised, suggesting irritation or early infection.
This type of swelling is often noticed early because it affects the smile area.
The image shows a blackened area on a back tooth, with swelling of the surrounding gum tissue. The dark spot on the tooth suggests advanced tooth decay, while the raised and irritated gum indicates a localized gum abscess or infection. This combination often causes bad taste or foul odor due to bacterial activity.
This condition usually develops when decay reaches deeper parts of the tooth and spreads toward the gum.
The image shows a localized swollen area on the gum near a back tooth, with redness and a raised appearance. The swelling is concentrated in one spot, which is commonly seen with a gum abscess or localized dental infection. The nearby tooth appears intact on the surface, but the infection may be coming from below the gumline or the tooth root.
This type of swelling can increase quickly if not treated.
Patients with lower front gum inflammation may also experience tartar buildup, periodontal disease, gum abscesses, or tooth decay. Explore these related clinical case studies.
