Many dentists warm composite by placing it on top of the operatory light, but I wonder what the patient is thinking when you reach for it on top of the light.
Some dentists have water heated in one of the green bowls from the lab. I wouldn’t do that either because I wouldn’t know the precise temperature, and water intrusion could occur into the composite syringe or compule.
Composite warmers are not a big expense in a dental practice. I have one in every one of our operatories. The warmers come with two interchangeable top pieces. One is designed for syringes, and one is designed for compules. They warm the composite to a specific temperature.
Science-Backed Benefits of Warmed Composites
When you heat composites, there’s no permanent change to the chemistry. As the composite is warmed, its viscosity is reduced, but as soon as the composite cools, it goes right back to its original viscosity.
Studies show that the reduction in viscosity results in better marginal adaptation because it is more flowable, softer for sculpting, and much easier for us to push it against the margins. We also get a greater depth of cure because composite polymerizes more effectively at reduced viscosity.
This reduces the shrinkage of the material and increases the longevity of our restorations.
Clinical Tips for Using Composite Warmers
One important tip: avoid leaving composite material in the warmer for days. Continuous heating will gradually evaporate monomers, leaving the material brittle or crumbly.
To get the most from your warmer:
- Have your assistant load the daily supply of composite in the morning or just before the appointment.
- Turn on the warmer while delivering anesthetic—the composite will be ready by the time you’re placing it.
- Make it a routine to turn off the warmer after each appointment.
