✅ Introduction
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia due to insulin deficiency or resistance. According to the American Diabetes Association, its prevalence continues to rise globally, significantly impacting oral health.
Tooth extraction is a common dental procedure, but in diabetic patients, clinicians must assess systemic status, glycemic control, and infection risk before proceeding.

In modern dentistry, recognizing these signs is key to preventive care and interdisciplinary treatment.✅ Diabetes and Its Consequences in the Oral Cavity
1. Periodontal Disease
Diabetes is strongly associated with periodontitis, often referred to as the “sixth complication of diabetes”. Poor glycemic control exacerbates inflammation and tissue destruction.
2. Delayed Wound Healing
Hyperglycemia impairs angiogenesis, collagen synthesis, and immune response, leading to prolonged healing after extraction.
3. Increased Risk of Infection
Diabetic patients exhibit reduced neutrophil function, increasing susceptibility to postoperative infections and abscess formation.
4. Xerostomia
Salivary flow reduction promotes caries, mucosal lesions, and opportunistic infections such as candidiasis.
5. Burning Mouth Syndrome and Taste Alterations
Neuropathic changes may cause oral discomfort and dysgeusia.

Indications
Dental extraction is recommended when:
▪️ Non-restorable teeth
▪️ Advanced periodontal disease
▪️ Acute infections or abscesses
▪️ Orthodontic or prosthetic needs
Key Consideration: Glycemic Control
▪️ Well-controlled diabetes (HbA1c less than 7%) → extraction is generally safe
▪️ Moderately controlled (HbA1c 7–8%) → proceed with precautions
▪️ Poorly controlled (HbA1c > 8%) → delay elective extraction

Preoperative
▪️ Evaluate HbA1c and fasting glucose
▪️ Schedule morning appointments
▪️ Ensure patient has eaten and taken medication
▪️ Consider antibiotic prophylaxis in poorly controlled cases
Intraoperative
▪️ Use atraumatic technique
▪️ Achieve adequate hemostasis
▪️ Minimize surgical time
Postoperative
▪️ Prescribe analgesics and antibiotics if indicated
▪️ Provide clear postoperative instructions
▪️ Monitor healing closely

This review discusses the clinical significance of odontogenic infections, their systemic implications, and the essential aspects dental professionals should monitor to prevent complications.💬 Discussion
Current literature emphasizes that the main determinant of postoperative complications is glycemic control, not the presence of diabetes itself. Studies published in journals such as the Journal of Clinical Periodontology highlight that well-controlled diabetic patients have similar healing outcomes to non-diabetic individuals.
However, poorly controlled diabetes significantly increases the risk of alveolar osteitis, infection, and delayed epithelialization. Therefore, interdisciplinary management with physicians is often necessary.
✍️ Conclusion
Dental extraction is safe in diabetic patients when proper glycemic control and clinical protocols are followed. The key lies in individualized risk assessment, atraumatic technique, and close postoperative monitoring.
🎯 Recommendations
▪️ Always assess HbA1c before elective procedures
▪️ Postpone extractions in uncontrolled diabetes
▪️ Use antibiotic coverage selectively
▪️ Educate patients on oral hygiene and glycemic control
▪️ Coordinate care with the patient’s physician
