Uses 3 LR44 batteries for each led which is supplied with the handy tools
These dental tools were timely,  I was dealing with an issue surrounding a partially emerged molar.  The lighted tools with magnifier made it easier to detect the problem.  The wedge tool was useful to place/massage a neem n tea tree oil based toothpaste into tge problem area,  helping to kill the microbes causing the problem.  Now the surface swelling is reducing,  the use of a Water Pik will prove to be more effective now to get a tea tree oil based mouthwash deeper into the root of the problem.  The dental tools use 3 LR44 batteries each,  which were supplied.  Be sure to have a few on hand when it's time to replace.  The dental tools were provided free of charge for reviewing purposes.  They are quality made and definitely unique with the handy built in led light!
