How to clean your voice prosthesis

Get to know the tools that will help you clean your voice prosthesis. Look after your voice prosthesis by cleaning it every day. This may delay leakage through the voice prosthesis meaning your device may have a longer lifetime.

Taking care of your voice prosthesis


The rear side of your voice prosthesis is located in your food pipe where food, drinks and saliva are being swallowed all the time.

We recommend cleaning your voice prosthesis in the morning, in the evening and after every meal, using the Provox Brush and Provox Flush. Make it a routine to brush regularly to prevent blockage and mucus build-up. Before brushing and flushing, wash your hands with warm, soapy water.

How to use Provox Brush


  1. Brush both morning and night and after each meal. Make sure the Provox Brush you use is clean at all times.
  2. Insert the brush into the middle of the voice prosthesis and move the brush back and forth a few times. Pull it back if you feel any resistance.
  3. If mucus or debris is stuck inside the voice prosthesis, try brushing with warm water.
  4. Ensure you have a good supply of Provox Brush available, in case you need to replace a dirty or damaged brush with a new one.

How to use Provox Flush


  1. When using the Provox Flush as a part of your cleaning routine, brush first and then flush.  Make sure the Provox Flush is clean at all times.
  2. Place the tip of the flush in water, squeeze the bulb and then release to draw water into the bulb. The tip of the flush is flexible to make insertion easier.
  3. Place the tip of the flush into the middle of the voice prosthesis and ensure it is completely flat against the voice prosthesis.
  4. Do not squeeze before the flush is placed into the voice prosthesis to avoid water dripping into your windpipe.

Tips for voice prosthesis leakage

Your mouth, throat and food pipe contain bacteria and yeast that will gradually stick to your voice prosthesis. Over time this will make your voice prosthesis leak.
