Lead light has a very long life.
And it’s often left in a closed room for long periods of time.
But a new study published in the journal PLOS ONE shows that a new LED-based tooth whitening toothbrush can significantly reduce the time it takes for the lead to break down and leave a white residue on your teeth.
Researchers at the University of California, Los Angeles, tested the tooth whitener on two groups of volunteers: One who took a daily brushing for three weeks and another who did not.
The lead-based whitening product reduced tooth decay by 42% on both groups.
The lead-free tooth whiteners are becoming more popular as tooth whitestrings become more popular and cheaper to buy.
But scientists have been trying to figure out how to make the tooth white and maintain that effect for as long as possible.
This new study suggests that the lead-containing tooth whiters could be made more effective at delivering the whitening effect for longer periods of the day.
Researchers say they hope to find new ways to improve the effectiveness of tooth whitings for both adults and children, especially when the white residue left behind is a small amount.
Lead-free whitening Toothbrush for AdultsThis toothbrush comes with a special “lead-free” coating that can be applied over the tooth to ensure the tooth stays whitened.
The coating does not absorb lead, and is a safe and non-toxic option for people with tooth decay.
The white coating lasts for up to five years and can be cleaned up with a toothbrush and water.
A new Tooth Whitening Tooth Brush for ChildrenThe toothbrush contains a whitening gel to give your teeth a white finish, which can be washed off with water or by wiping with a soft cloth.
The whitening is also safe for children.
The whitening brush is made from a non-polar material, which means that it absorbs only the lead, not the aluminum, that causes lead-to-lead in the toothpaste industry.
This helps prevent lead-contaminated toothpaste from causing problems for kids and adults.
The research team is still working on getting the lead from the toothbrush tested and then tested to see if the lead could help the whiteners whiten teeth.
The study also looked at the effect of the whitener’s other ingredients.
One ingredient in the whitened toothbrush is a protein that helps to protect the tooth from damage during the manufacturing process.
This protein is made in large quantities by the tooth-care industry and could have an effect on the whiteness of the tooth brush.
The researchers say they are still testing the effects of other ingredients, but they hope that the whiteners whitening process will lead to more effective tooth whitens.
