How to Recycle or Dispose of an Old Toothbrush

First, know what can be recycled

If you are asking how to recycle an old toothbrush, the honest first answer is: most toothbrushes cannot go into your regular curbside recycling bin. A typical manual brush combines a plastic handle with nylon bristles held in place by tiny staples. Those materials are fused together and difficult for a standard sorting facility to separate. The same is true for most electric toothbrush heads, which add a metal base and internal parts to the plastic.

That does not mean the pieces are worthless. Many components can be recycled through specialized programs, and some brands offer takeback programs for their own handles, brush heads, and packaging. Check the brand's website before throwing anything away. If the brand you use has a recycling program, that is usually the cleanest option.

If no program is available, separate the brush into its parts first. The handle, the head, and the bristles often need different treatment. For a powered brush, the handle also contains a battery and electronic components that should not go in the regular trash in most places. See the toothbrush brand recycling programs guide for more details on which manufacturers collect their own products.

• Curbside recycling rarely accepts whole toothbrushes.
• Brand takeback and specialty recycling programs are the main route for plastic brush bodies.
• Always remove and dispose of batteries and electronic parts separately.
• Cardboard packaging is usually recyclable in the curbside bin.

How to dispose of a manual toothbrush

For a manual toothbrush, the simplest safe method is to place the whole brush in the trash once it has reached the end of its usable life. The ADA recommends replacing toothbrushes every three to four months or more often if the bristles are visibly matted or frayed. Before disposal, rinse the brush and let it dry. There is no medical or safety reason to do anything more elaborate, but removing toothpaste residue helps keep the waste stream cleaner.

If you want to keep the brush out of a landfill, look for a specialty recycler that accepts oral care products. These programs collect used brushes and separate the plastic parts for reprocessing. Some programs require you to mail in the brushes; others provide drop-off bins at participating retailers or community locations. Always follow the program's instructions, since accepted materials vary.

Do not put a manual toothbrush in the recycling bin just because the handle has a recycling symbol on it. The chasing arrows symbol does not guarantee that your local facility can process the specific plastic blend used in toothbrushes. When in doubt, throw it out or use a verified specialty program.

How to dispose of an electric toothbrush head

Electric toothbrush heads are also mostly non-recyclable in the curbside bin. The plastic head, nylon bristles, and small metal staple are fused together in a way that standard recyclers cannot separate. Many people replace these heads every few months, so they add up quickly.

Check whether the toothbrush manufacturer offers a takeback program for brush heads. Some brands collect used heads and recycle the plastic into new products. If your brand does not offer one, search for an oral care recycling drop-off near you. These programs generally accept heads from multiple brands, but confirm before you go.

If no recycling option exists, place the head in the trash. Do not try to remove the bristles or pry out the metal staple first. That can create small, sharp pieces and is not necessary for safe disposal. Simply wrap the head in a paper towel or small bag before tossing it if you prefer, but that is optional.

Because the head is the replaceable part, you can also reduce waste by choosing a brush with a long warranty and a reliable replacement schedule. See how often to replace a toothbrush head and brush head replacement indicators for signs that a head is ready to retire.

How to dispose of an electric toothbrush handle

An electric toothbrush handle should not go in the regular trash in most communities because it contains a rechargeable battery and electronic circuit board. Many jurisdictions classify these as electronic waste. The safest approach is to take the handle to a local electronics recycling drop-off or a retailer that collects small electronics. Call ahead to confirm they accept toothbrushes.

If you are comfortable opening the handle, remove the rechargeable battery before disposal. Look up the specific model's disassembly instructions from the manufacturer. If you cannot remove the battery safely, do not force it. Take the whole handle to an electronics recycler instead.

Some toothbrush makers now offer mail-back recycling for their handles. The program usually asks you to send the handle in a prepaid box, and the manufacturer manages the material recovery. This is a convenient option for people who want to avoid a trip to a drop-off site. Check the brand's page before you recycle.

How to prepare a toothbrush for recycling or disposal

A little preparation makes both recycling and disposal safer and more effective. Start by rinsing the brush head under warm water to remove toothpaste and debris. The ADA says to rinse the toothbrush thoroughly after each use to remove any remaining paste and debris, and this final rinse is just as important before disposal.

For manual brushes, let the brush air dry completely before you put it in a bag or box. For electric brushes, remove the brush head and wipe down the handle. If you are mailing the brush to a recycler, use a sturdy envelope or small box and follow the program's shipping rules.

Some programs ask you to bundle multiple heads together or remove batteries. Others only accept certain brands. Read the instructions on the recycler's website carefully. Misdirected materials can slow down the whole process or end up in the trash anyway.

Storage tip: keep old brushes in a separate cup or drawer while you collect enough for a mail-in program. Do not mix them with your current toothbrushes. For ways to store spare heads and brushes cleanly, see how to store extra toothbrush heads and how to dry and store a toothbrush.

Common mistakes to avoid

Do not put toothbrushes in the curbside recycling bin just because you hope they will be recycled. Contamination is a real problem for recycling facilities, and a single non-recyclable item can cause a whole batch to be discarded. The same applies to electric toothbrush heads and handles.

Do not microwave a toothbrush or put it in the dishwasher to clean it before disposal. The ADA specifically recommends against microwaving toothbrushes or putting them in the dishwasher because such high heat may damage the brush. That advice is meant for cleaning, but it also means those methods are not a sensible way to prepare a brush for recycling.

Do not burn a toothbrush. The plastic and bristles can release fumes, and the metal parts in electric heads can be hazardous. Municipal trash pickup is safer than burning.

Finally, do not keep a toothbrush past its useful life just to avoid throwing it away. An old, frayed brush cleans less effectively. The ADA says toothbrushes should be replaced approximately every three to four months or more often if the bristles become matted or frayed. When the brush has done its job, dispose of it responsibly and start with a fresh one.

How to reduce toothbrush waste from the start

Recycling is the last step, not the only step. You can reduce how many old brushes you throw away by choosing a longer-lasting product and using it correctly. A powered toothbrush with replaceable heads creates less handle waste over time than buying a new manual brush every three months, because you keep the same handle for years.

Look for brushes with replaceable heads and a design that makes replacement easy. Many of the guides on this site compare models by the number of included heads, head styles, and replacement options. Start with best toothbrushes with many brush heads, best rechargeable toothbrushes, or best battery powered toothbrushes to see which approach matches your habits.

Also consider the packaging when you buy. Cardboard boxes are recyclable in most curbside programs, while plastic clamshell packaging is harder to recycle. If sustainability matters to you, choose brands that use paper packaging and that publish a recycling program for their products.

What to do with an old toothbrush

Questions

Can I put a toothbrush in the recycling bin?

Usually no. Most curbside recycling programs cannot process toothbrushes because the plastic, nylon bristles, and metal staples are fused together. Check with your local program, but plan to use a specialty oral care recycler or the trash.

Are electric toothbrush heads recyclable?

Only through specialty programs. The head is made from several materials that standard recyclers cannot separate. Some manufacturers and oral care recyclers accept brush heads by mail or at drop-off locations.

What should I do with an electric toothbrush handle?

Treat it as electronic waste because it contains a rechargeable battery and circuit board. Take it to an electronics recycling drop-off or use a brand mail-back program. If you can safely remove the battery, do so before disposal.

How often should I replace my toothbrush?

The ADA recommends replacing toothbrushes every three to four months or more often if the bristles are visibly matted or frayed. Worn bristles clean less effectively, so do not keep a brush too long simply to avoid disposal.

Can I compost a toothbrush?

No. Traditional plastic handles and nylon bristles do not break down in a home compost bin. Bamboo handles may be compostable if the bristles are removed, but check the brand's instructions. Nylon bristles still need to go in the trash.

Should I remove the bristles before throwing away a toothbrush?

No. Removing nylon bristles or prying out the metal staple creates sharp pieces and is not necessary. The whole brush can go in the trash, or the whole brush can be sent to a specialty recycler that accepts it.
