Will Teeth Whitening Strips Work on Fillings?

Wondering if teeth whitening strips can brighten fillings? The short answer: no. Since fillings are made of materials that don't respond to whitening agents in the same way as natural tooth enamel, the strips usually won't change their colour. However, this article will explore this topic in more depth, examining the effectiveness of whitening treatments on various dental restorations, including fillings, crowns, and veneers. Keep reading to uncover more insights and considerations for achieving a brighter smile.

Understanding Teeth Whitening.

Natural teeth whitened because the peroxide agents effectively target and reduce discoloration within the enamel. Achieving whiter teeth through these treatments can boost confidence and improve the overall appearance of your smile.

Beyond aesthetics, teeth whitening can improve oral health by motivating individuals to adopt better hygiene practices. It can lead to reduced risk of gum disease and tooth decay, as people are more inclined to brush and floss regularly to maintain their bright smiles.

Psychologically, a whiter smile can enhance social interactions and opportunities, as it is often perceived as a sign of health, success, and attractiveness. This can contribute to improved mental well-being and quality of life.

When is the Best Time to Whiten Teeth

Like fillings, dental crowns and veneers made from ceramic, porcelain, or composite resin do not respond to whitening treatments. As a result, patients with these restorations may notice uneven whitening results, with natural teeth becoming whiter than the restored teeth.

It's generally recommended to whiten your teeth before getting new fillings, crowns, or other dental restorations. This approach allows the dentist to match the colour of the new restorations to your newly whitened teeth, ensuring a uniform appearance.

After whitening, there should be a waiting period to allow for the colour to stabilise before adding fillings or making other restorations. Always consult with your dentist for personalised advice and to plan your treatments effectively.

Dissolving Whitening Strips

Dissolving Whitening Strips are a modern convenience in teeth whitening, designed to be used on the go without the need for removal or rinsing. These strips are made of a thin, flexible material that adheres to the teeth and gradually dissolves within minutes, releasing whitening agents to brighten the teeth.

Key Features:

  • Self-Dissolving: The primary feature of dissolving whitening strips is their ability to dissolve completely in the mouth, leaving no residue behind. This makes them exceptionally convenient for users with busy lifestyles or for those who require a quick whitening touch-up.
  • Milder Whitening Effect: Given their shorter application time and the nature of the formulation, dissolving whitening strips like that in Bliss Oral Care  typically offer a milder whitening effect. They are ideal for maintaining the brightness of your smile between more intensive treatments.
  • Ease of Use: Dissolving whitening strips eliminate the need for a post-treatment cleanup process, making them highly user-friendly and perfect for whitening teeth anywhere, at any time.

Best For:

  • Individuals looking for a quick and convenient whitening solution.
  • Those seeking to maintain their whitening results without committing to a lengthy treatment process.
  • Users who prefer a no-mess, hassle-free whitening option.

Leave-In Whitening Strips

Leave-In Whitening Strips are designed for more intensive whitening treatments. They are applied to the teeth and left in place for a specific period, typically ranging from 30 minutes to 2 hours, depending on the product's formulation. These strips use a potent whitening gel that works to remove deeper stains and discoloration.

Key Features:

  • Intensive Whitening: With a higher concentration of whitening agents and a longer application time, leave-in strips are capable of delivering more dramatic whitening results. They are effective at targeting stubborn stains, including those caused by coffee, tea, and tobacco.
  • Non-Slip Design: Leave-in whitening strips often feature a non-slip grip, allowing them to stay securely in place during the treatment period. This ensures that the whitening gel remains in consistent contact with the teeth for optimal results.
  • Application Process: Unlike dissolving strips, leave-in whitening strips require manual removal after the treatment duration is complete. This necessitates a brief cleanup, usually involving rinsing the mouth to remove any remaining gel.

Best For:

  • Individuals seeking significant whitening results and are willing to commit to the treatment duration.
  • Users with noticeable teeth discoloration looking for a potent at-home whitening solution.
  • Those who are planning a whitening regimen ahead of time and can allocate the required treatment period.
