Dental Case Analysis: Severely Decayed Back Tooth (Lingual Side)

Zoom 100% Visual Examination

Observed Findings

• Large open cavity on the back tooth

• Extensive brown and dark discoloration indicating active decay

• Loss of enamel with exposed dentin

• Cavity extends toward the inner (lingual) surface

• High risk food and bacteria retention area

• Surrounding gum tissue appears irritated

• Tongue positioned close to the decayed area, increasing discomfort risk

Diagnosis

Primary Diagnosis

• Advanced dental caries (severe tooth decay)

Secondary Diagnosis

• Possible pulp involvement

• High risk of infection or abscess formation

Treatment Objective

• Eliminate infection and decay

• Relieve pain and sensitivity

• Preserve the tooth if possible

• Prevent spread to adjacent teeth and gums

Treatment Process to Execute

Step-by-Step Plan

1. Comprehensive dental examination and X-ray

2. Complete removal of decayed tooth structure

3. Pulp vitality assessment

4. Treatment options:

   • Deep composite restoration (if pulp is intact)

   • Root canal treatment (if nerve is affected)

   • Tooth extraction if damage is non-restorable

5. Final restoration with crown or replacement planning

Healing and Treatment Time Frame

First 14 Days

• Pain and sensitivity decrease after treatment

• Gum tissue begins healing

• Infection risk is reduced

After 14 Days

• Normal chewing comfort improves

• Tooth function stabilizes

• Full healing continues depending on treatment type

If Treatment Is Delayed

Issues That May Scale Up

• Severe toothache

• Dental abscess or swelling

• Spread of infection to jawbone

• Tooth fracture

• Tooth loss requiring implant or bridge

Professional Comments

• This condition is urgent and progressive

• Delay significantly increases treatment complexity

• Early intervention may save the tooth

• Lingual-side decay often worsens quickly

Recommendation

Seek dental treatment as soon as possible to prevent complications.
