Do you really need to change your toothbrush? YES!

I am slightly neurotic about getting all of us to the dentist twice a year. Of course, at each of these dentist appointments we get a new toothbrush. That means 8 old toothbrushes need to find new uses every single year.

On top of that, I tend to replace toothbrushes randomly when they are looking particularly worn or someone is sick. I am always looking at those old toothbrushes and wondering what in the world I can do with them besides throw them away.

I decided I needed to put together a list of things that I could do with them so I can stop feeling so guilty every time one ends up in the trashcan. Once you find a new use for your old toothbrush, check out my other eco friendly bathroom ideas as well.

10 Creative Old Toothbrush Uses 

There are dozens of ways to reuse old toothbrushes instead of throwing them right in the trash.  Here are just a few upcycling tips to help you get started.

Clean the dog’s teeth: 

They make fancy doggie toothbrushes but couldn’t I just use one of our old toothbrushes instead? Along with some canine toothpaste I bet it would go a long way towards freshening up her breath!

Bathroom cleaning: 

I know I’m not the only one who gets that nasty buildup at the bottom of the sink faucets. Old toothbrushes are great for scrubbing that away. Or, clean the toilet.  Even better, make the KIDS clean the toilet!

Clean computer keyboards: 

All that crud that falls in between your keys because you are snacking while you type? Old toothbrushes are great for getting into those crevices!

Scrub your nails: 

After gardening I always have tons of dirt under my nails. Old toothbrushes are just like fancy nail brushes only much cheaper!

Clean your cheese grater: 

I hate trying to get the cheese grater clean, especially when my wash rag just gets stuck in those sharp little holes!

Clean jewelry: 

If you wedding ring is looking a little bit dull just use an old toothbrush along with some jewelry cleaner and get it looking brand new.

Old toothbrush crafts: 

Hand your kids an old toothbrush, some paint and some paper and see what sort of masterpiece they can come up with. Other crafty uses for old toothbrushes include things like

  • Scrub out glass bottles before upcycling them into something new.
  • Clean calligraphy pen tips.
  • Add texture to clay.
  • Use them to splatter paint for an upcycled furniture or art piece. 
  • Use an old clean toothbrush as a tool to brush out or fluff flosses and yarns. 

Garden markers: 

Use a sharpie to write on the handle of your toothbrush and bury the ‘head’ in the soil. Now you know where your tomatoes are and which plants are your peppers!

Remove crayon marks from the wall: 

Along with a bit of shaving cream, you can scrub crayon marks off the wall with your old toothbrushes.

Remove mud from the treads of sneakers:

Instead of having your kids leave bits of dried mud all over the house, clean the soles of their sneakers with old toothbrushes.
