Can You Put Mouthwash in a Waterpik Water Flosser?

Water flosser is a great complement to your daily brushing and flossing routine as it helps to remove any food that may be stuck between your teeth. While only water is required for an effective water flossing, can you put actually mouthwash in it?

The answer is YES; it is perfectly safe to use a mouthwash in your Waterpik water flosser. In fact, the habit is recommended by several dentist due to the health benefits of mouthwash. However, there is currently no clinical study or scientific research to support the any claim that the use of mouthwash in your water floss routine will provide any additional benefits beyond the use of warm water alone.

What is a Water Flosser?

Water flosser, or oral irrigator, is a dental device that jets out water to dislodge food particles that are stuck between your teeth. This is achieved through the use of a motorized pump which pumps out pressurized water out of the nozzle tip and into the mouth.

A water flosser helps to removes plaque and prevents tartar, a brown colored deposit that forms when plaque hardens, from forming on the teeth. According to American Dental Association (ADA), water flossers that have received the ADA Seal of Acceptance are all proven to have shown efficacy in removing plaque from the teeth.

Plaque is a sticky film made up of millions of bacteria. These bacteria feeds on any leftover food particles in the mouth and produces acid which over time, destroys the tooth enamel and leads to periodontal diseases such as gingivitis and periodontitis.

While water flosser should not replace your toothbrush, it serves as a great alternative to traditional flossing. This is especially so for people who have had dental work (such as braces) where waxed string flossing would be difficult to use.

In fact, a 2013 clinical study found out that the water flosser group was 29% more effective than the waxed string floss group at removing plaque from the surface of the tooth. This is primarily due to the ease of using a water flosser as compared to a string floss; the latter requires skills to identify areas where plaque still lingers as well as the dexterity to utilize the string floss.

There are generally three types of water flosser:

  • Countertop. This is the most common and heaviest of the three. It offers a larger water reservoir, more pressure settings, and more advanced features, making a favourite among those who uses a water flosser at home.
  • Cordless. A cordless (also known as travel) water flosser is essentially a miniature version of its countertop counterpart. However, it has a smaller water reservoir, less settings and a lower water pressure.
  • Shower/Faucet: This style of water flosser is attached directly to your sink and shower and does not require any electricity. While it offers much less feature and control over the water pressure, it does not require a water reservoir.

Today, Waterpik remains the most popular brand of water flosser.

  4. After your routine, clean the unit by filling up the reservoir with warm water. Rinse the inside of the nozzle by pointing the tip into the sink

There are many who believes that mouthwash should not be put in a water flosser as the mixture could cause damage to the device. This is partially true, as a high concentration of mouthwash could ruin the plastic parts of the device. There are several other things you need to take note of when adding a non-water solution to your water flosser:

  • Avoid exceeding the 1:1 ratio of mouthwash to water.
  • Avoid adding essential oils (such as eucalyptus oil, tea tree oil, or spearmint oil)
  • Avoid adding bleach or a diluted bleach solution.
  • Avoid adding iodine or a diluted iodine solution
  • Always rinse the machine (including the water reservoir and the nozzle) after using a solution other than water.

Ignoring any of the above warning may dramatically reduce the performance and lifespan of your Waterpik water flosser. Also, be aware that the addition of any additives into your water flosser may void the warranty of the product.
