Recommended Storage Media for Avulsed Teeth – Avoid Normal Saline
Guideline Rankings of Storage Media
The 2024 American Heart Association and American Red Cross guidelines rank storage media according to periodontal‑ligament (PDL) cell viability 1.
Second‑tier (acceptable) options
Third‑tier (last‑resort) options
Explicitly NOT recommended
Evidence Against Normal Saline
The 2020 International Consensus advises using cow’s milk rather than tap water, buttermilk, castor oil, turmeric extract, or saline when better options are unavailable. [2, 4]

Temperature Effects on Storage Media
Key Clinical Recommendations
Avulsed Tooth Care
Immediate On-Site Management
- The American Heart Association recommends attempting immediate reimplantation of an avulsed permanent tooth after briefly rinsing the tooth (<10 seconds) while handling only the crown, then seeking emergency dental care, as periodontal ligament cell death begins within minutes 5, 6, 7
- Handle the tooth only by the crown, never touch the root surface, as the periodontal ligament fibroblasts on the root are fragile and essential for successful reattachment 8
- The likelihood of successful reimplantation decreases rapidly with every minute the tooth remains out of the socket, particularly as the periodontal ligament dies or becomes injured 5, 6, 7
Storage Solutions When Immediate Reimplantation Is Not Possible
- The American Heart Association and American Red Cross Guidelines provide a clear hierarchy of storage media based on periodontal ligament cell viability, with Hanks Balanced Salt Solution, oral rehydration salt solutions, propolis, rice water, and cling wrap being the best options 5, 6, 9
- Tap water should never be used for storage as it damages periodontal ligament cells 5, 6, 9
Emergency Dental Referral
- All patients with avulsed permanent teeth require immediate dental or medical care, whether or not reimplantation was successful 5, 6, 10, 8
- Time is the most critical factor—the extra-alveolar dry time directly correlates with tooth survival 7, 11, 10
Expected Dental Treatment
- The dentist will place a flexible splint for 2 weeks after reimplantation 10, 8
- Root canal therapy will be required within 7-10 days after reimplantation for most avulsed teeth 10, 8
Special Considerations
- Avulsed primary teeth should never be reimplanted to avoid damage to the developing permanent tooth germ 10
- Monitor for complications including pulpal necrosis, root resorption, ankylosis, tooth loss, and gingival abscess 10, 8
