When a tooth begins to crumble, the damage often extends beyond what can be seen on its surface. Dental caries, commonly called tooth decay, develops when acids produced by plaque bacteria dissolve minerals from the enamel and dentin.
The image shows the upper and lower dental arches with multiple teeth affected by advanced decay, visible dark cavities, broken tooth structure, and inflamed gum tissue. Several teeth show severe enamel and dentin destruction, indicating a high-risk oral condition requiring urgent dental care.
“My back teeth hurt and smell bad. I noticed dark spots and some swelling around the gum area.”
After close examination of the photo:
Visible dark spot (cavity) on one molar — likely tooth decay or caries.
This intra-oral image shows a tooth with advanced decay and an associated localized gum swelling above the affected tooth. The appearance suggests an active dental infection likely originating from deep caries that has reached the pulp and spread toward the surrounding soft tissue.
Deep cavity with visible tooth structure breakdown
The image strongly suggests a case of Severe Tooth Decay and Possible Pulp Exposure. The pain shown in the right panel indicates a severe toothache, which often means the decay has progressed to the innermost part of the tooth (the pulp), causing irreversible pulpitis or a dental abscess. This requires urgent professional attention.

Case Type: Advanced Dental Caries and Calculus Accumulation
This case shows severe tooth decay affecting the back teeth, with decay extending close to or into the tooth roots. Dark, broken tooth structure is visible, which indicates long-standing dental caries. The surrounding gum tissue appears irritated, increasing the risk of infection.
Rooted tooth decay usually develops when cavities are left untreated for a long time. Bacteria spread deeper into the tooth and reach the root area, making the tooth weak, painful, and difficult to save.
A severely broken tooth is more than a cosmetic concern. When extensive decay or a fracture exposes the inner pulp, bacteria can reach the nerves and blood vessels inside the tooth, causing inflammation, pulp death, or infection around the root. In some cases, an abscess develops in the surrounding gum or bone.
Common warning signs include:
A tooth that has broken close to the gumline.
Persistent, throbbing, or biting-related tooth pain.
The image shows the lower dental arch with visible metallic (amalgam) restorations on posterior molars. There are signs of plaque accumulation and dark staining within the grooves of treated teeth.
Multiple amalgam (silver) fillings on lower molars
Dark discoloration around restoration margins
Multiple decayed lower molars can increase the risk of deep tooth infection, dental abscesses, gum swelling, and tooth loss. When decay reaches the dental pulp, bacteria can spread through the root into surrounding tissues. Prompt dental examination, appropriate X-rays, and definitive treatment can help control infection and preserve teeth when possible.
Patients with lower front gum inflammation may also experience tartar buildup, periodontal disease, gum abscesses, or tooth decay. Explore these related clinical case studies.
