Therapeutic Guidelines has released a major Oral & Dental update (published September 2025) covering antibiotics, trauma, anxiety/sedation, mucosal disease, pain, comorbidities and peri-procedural safety. It tightens antimicrobial stewardship, modernises emergency and trauma care, and adds practical tools like flow charts, checklists and photo libraries to support day-to-day decisions in Australian dental practice.
Key Summary
- Antibiotics & infections: timing of definitive treatment now guides antibiotic choice; penicillin “allergy” advice is clarified.
- Emergency/trauma & sedation: refreshed pathways (with photos), consolidated safety for minimal sedation and child-specific considerations.
- Red flags & prevention: stronger oral-cancer red flags, mucosal updates, and concise peri-procedural risk tables.
Antibiotics & Acute Care: What’s New
Odontogenic infection — timing now drives antibiotic choice
For non-severe spreading infection, the recommended antibiotic depends on when a procedure will occur:
- Procedure within 24 hours: use penicillin monotherapy.
- Procedure delayed: step up to penicillin + metronidazole or amoxicillin–clavulanate to ensure anaerobic cover.
A new emergency flow chart highlights severe local/systemic features (including sepsis cues) and helps teams decide when to escalate care. For quick reference during drills or induction, you can review the Therapeutic Guidelines medical-emergencies flow chart.
Penicillin “allergy” rationalised
Guidance now distinguishes non-severe from severe hypersensitivity more clearly. Cefalexin is preferred for non-severe penicillin hypersensitivity; reserve clindamycin for severe hypersensitivity, supporting stewardship while keeping patients safe.
Trauma — updated pathways with photo-guided steps
There is refreshed guidance for fractures and luxations, including photo-guided splinting. For avulsed permanent teeth, amoxicillin is now preferred; use doxycycline only if the patient is penicillin-hypersensitive. The guidance also reminds clinicians to consider non-accidental injury where presentations raise concern.
Sedation, Pain & Peri-Procedural Safety
Anxiety & minimal sedation
Non-pharmacological approaches come first. If these are inadequate, updated minimal-sedation guidance supports careful use of benzodiazepines with dose adjustment at subsequent visits, along with consolidated safety requirements. There are specific notes for children, including monitoring and recovery considerations.
Acute & chronic pain
Tapentadol is included as an alternative where oxycodone is not tolerated (subject to state/territory controls). Chronic orofacial pain content is expanded with clearer referral indicators for temporomandibular disorders and other persistent pain presentations.
Peri-procedural risk management (quick reference)
A new table groups procedure classes and prevention strategies for bleeding, infective endocarditis, surgical-site infection, MRONJ and adrenal crisis. Articaine is added as an option for nerve blocks where appropriate.
Red Flags & Broader Oral Health: When to Escalate and Who to Involve
Oral mucosal disease & red flags
The update adds practical content on oral pigmented lesions and oral syphilis, plus photo libraries for infectious presentations such as HFMD, HSV and zoster. It emphasises oral-cancer red flags and when to refer for biopsy or specialist review.
Caries & periodontitis
Caries staging is aligned with ICDAS, and there is renewed emphasis on using fluoride varnish and silver diamine fluoride in high-risk patients. Periodontitis adopts the EFP 4-step approach with links to concise infographics for team training.
Sleep-related breathing disorders
There is a clearer role for dentists in identifying obstructive sleep apnoea and using mandibular advancement appliances in collaboration with sleep physicians and GPs.
Comorbidities, emergencies & prescribing hygiene
Planning guidance is expanded for patients with bleeding risk, obesity, cancer therapy, cognitive disability, neurodegeneration, and renal or hepatic failure. The package also provides printable first-aid flow charts for in-practice emergencies, and refreshed examples of correct prescription formatting, including considerations for compounded and off-label medicines and requirements around medicine supply by dentists.
Conclusion
The September 2025 Oral & Dental overhaul is intentionally practical: antibiotic choices tied to treatment timing, clearer trauma and emergency pathways, safer sedation guidance, and stronger red-flag signalling. Most teams will feel the benefits in day-to-day cases and in better preparedness for rare events. Scheduling a short internal review—updating protocols, induction packs and chairside references—will help your practice make the most of the new tools.

FAQs
- What’s the biggest practical shift for everyday dentistry?
Antibiotic selection for odontogenic infection now depends on whether definitive dental treatment is within 24 hours or delayed, supporting stewardship and safer care.
- How has penicillin “allergy” guidance changed?
Cefalexin is preferred in non-severe hypersensitivity, while clindamycin is reserved for severe hypersensitivity, under clearer severity definitions.
- Where can we access the emergency flow chart?
You can review it here: Therapeutic Guidelines medical-emergencies flow chart.
- What else should teams review first?
Trauma pathways (including avulsion antibiotics), minimal-sedation safety notes (especially for children), red-flag lists for mucosal disease and oral cancer, and the peri-procedural risk table for bleeding, endocarditis, SSI, MRONJ and adrenal crisis.
