Can You Swallow Teeth Whitening Strips?

Teeth whitening is a popular aspect of cosmetic dentistry, with teeth whitening strips being a sought-after option. However, questions about their safety, particularly regarding the risk of swallowing them, are prevalent. This article provides an in-depth analysis of the risks and safety measures associated with teeth whitening strips.

The Appeal of Whitening Strips

Teeth whitening is a significant part of cosmetic dentistry, offering a non-invasive method to enhance the appearance of teeth. Among various whitening products, whitening strips have gained popularity for their ease of use and effectiveness. These thin, flexible strips are coated with a whitening gel, typically containing hydrogen peroxide or carbamide peroxide, and are applied directly to the teeth.

The simplicity and convenience of whitening strips make them a favoured choice for those looking to brighten their smile. They are readily available over the counter and can be used in the comfort of one's home.

Concerns Associated with Swallowing Teeth Whitening Strips

Most adults, swallowing a teeth-whitening strip is likely to be of minor consequence, primarily leading to mild gastrointestinal discomfort. The risk is further minimised if the strip is swallowed after it has been in use for some time, reducing the concentration of hydrogen peroxide. .

Mild Effects in Adults: If a strip is ingested, it may result in minor gastrointestinal irritation, primarily due to the hydrogen peroxide content. However, these effects are typically mild and short lived. This is similar to the effects of ingesting low concentrations of hydrogen peroxide solution (3-10%), which usually results in mild gastrointestinal irritation.

Safety Measures and Best Practices

Follow Manufacturer Instructions and Recommendations

When using teeth whitening strips, it's essential to strictly adhere to the manufacturer's instructions and recommendations to ensure both safety and effectiveness. This means carefully reading and following the provided guidelines regarding how long the strips should be worn, how frequently they should be applied, and the overall duration of the treatment. It's also crucial to observe any age restrictions specified by the manufacturer

Practise Safe Use to Prevent Accidental Ingestion

To minimise the risk of accidental ingestion of teeth whitening strips, it's important to practise safe usage habits. Firstly, while wearing the strips, try to limit oral activities such as eating, drinking, or excessive talking. This precaution helps prevent the strips from dislodging and being accidentally swallowed. Secondly, it's advisable to apply the whitening strips only during your waking hours. Doing so allows you to quickly address any potential issues, such as discomfort or the strip becoming dislodged, which could lead to accidental swallowing. Lastly, storing the strips properly is crucial. Keep them out of reach of both children and pets, as the packaging and the strips themselves might be intriguing to them. 

Handling Excess Saliva

The use of whitening strips often leads to heightened saliva production. It's crucial to be mindful in swallowing this excess saliva, ensuring the strip itself is not ingested. Notably, with specific brands like Bliss Oral Care Whitening Strips, swallowing saliva during the application is perfectly safe.


Teeth whitening strips have emerged as a popular and convenient option within cosmetic dentistry for enhancing dental aesthetics. These strips, often containing hydrogen peroxide, are simple to use and effective in breaking down stains for a brighter smile. 

While generally safe, the concern about accidentally swallowing these strips is valid. Small accidental ingestions are typically harmless, passing through the digestive system without severe consequences. However, swallowing multiple large pieces might lead to stomach discomfort and necessitating caution.

Using the strips correctly and being aware of saliva management, especially with brands like Bliss Oral Care, where swallowing saliva is safe and normal.
