Avoiding Hot Fluids After Tooth Extraction
You should avoid hot fluids for 24 hours after tooth extraction, then may introduce warm (not hot) fluids as tolerated. 1
Critical First 24-48 Hours
The first 24-48 hours after extraction are the most critical period for blood clot formation and initial healing. 1 During this time:
- Begin with clear liquids at room temperature for the first 24-48 hours post-extraction 1
- Room temperature fluids prevent disruption of the blood clot, which is essential for proper healing 1
- Hot fluids can potentially dissolve or dislodge the blood clot during this vulnerable period 1
Progression Timeline
After the initial 24-hour period, you can gradually advance fluid temperature:
- At 24 hours post-extraction: Begin gentle rinsing with warm salt water 2
- After 24-48 hours: Warm (not hot) fluids may be introduced as tolerated 1
- The key is avoiding extremes of temperature that could disturb the healing socket 1
Why Temperature Matters
The primary concern is preserving the blood clot that forms in the extraction socket:
- Sucking motions and temperature extremes can potentially dislodge this blood clot, leading to complications like dry socket 1
- Dry socket (alveolar osteitis) develops in 1-5% of routine extractions and up to 30% in surgically extracted third molars 3
- The blood clot is essential for proper healing and preventing infection 1
Additional Precautions During Healing
Beyond avoiding hot fluids, you must also:
- Avoid forceful spitting, using straws, or any actions creating negative pressure in the mouth during the initial healing period 1
- These sucking motions are more dangerous to clot stability than temperature alone 1
- Avoid medicated lozenges for at least 7 days after extraction or until substantial healing has occurred 1
Salt Water Rinses
Once the initial 24-hour period has passed:
