Thermoform Whitening Trays: Everything You Need To Know

News, Whitening

If you’re looking for an at-home solution to whitening your smile, Thermoform Whitening Trays may be the answer. Discover how these whitening trays work, how to use them, and why we love them.

What are Thermoform Whitening Trays?

Thermoform, or boil and bite trays, are reusable, self-moulding teeth whitening trays designed to fit snugly over a person’s teeth whilst holding a tooth whitening solution against the teeth. They are made from pliable plastic material, which can be moulded to the shape of a person’s teeth using heat – usually hot water.

Thermoform whitening trays are a popular and cost-effective option for at-home teeth whitening, offering a comfortable and simple whitening tray option for maximum results.

Depending on your requirements, Thermoform Whitening Trays can be conveniently purchased in 2pks and 3pks online with most users purchasing a 3pk (one for your upper and lower teeth, and one spare).

How do Thermoforming Whitening Trays Work?

Thermoform Whitening Trays work by holding a tooth whitening solution against the teeth for an extended period. The trays are typically made from a type of plastic such as silicon or ethylene-vinyl acetate (EVA) which is safe for use in the mouth and can withstand the bleaching agents used in teeth whitening solutions.

Firstly, using your fingers and mouth the trays are softened in hot water and then moulded or shaped to your teeth and gums. This process is like the one followed for a boil and bite mouthguard, or a mouthguard purchased from a chemist. This process can be completed several times (using the same Thermoform Trays) to ensure the tightest and best fit. Once the trays have been moulded, they are left to cool for about 10-15 minutes and can be trimmed (optional) for optimal fit.

To use Thermoform Whitening Trays, a person applies a small amount of teeth whitening gel to the trays and then places them over their teeth. The trays are worn for a specified amount of time, typically anywhere from 30 minutes to several hours per day, depending on the strength of the whitening solution and the desired results. Over time, the whitening solution penetrates the enamel of the teeth, breaking down stains and discoloration to reveal a brighter, whiter smile.

How do Thermoform Whitening Trays Compare?

Thermoform whitening trays are a convenient and cost-effective way to achieve a whiter smile without the need for expensive in-office treatments. Thermoforming trays can also serve as an excellent starter option for users who are new to teeth whitening, are wanting to try a particular teeth whitening gel/brand for the first time or are on a budget.

As Thermoforming trays are typically made from a thermoplastic material that can be softened by heating and then self-moulding to the shape of your teeth, the often less precise than that of custom fit whitening trays, which can sometimes lead to uneven whitening and discomfort during use. For this reason, Thermoforming Whitening Trays are recommended for whitening gels up to and including 6% Hydrogen Peroxide or 18% Carbamide Peroxide in strength.

In contrast, custom fit whitening trays are created using a specialised moulding process that creates a precise fit to the individual’s teeth. This allows for better contact between the whitening solution and the teeth, resulting in more effective and even whitening. Additionally, custom fit trays are typically more comfortable to wear than thermoform trays, as they are made from a thinner (usually 1mm) and more pliable material that conforms to the contours of the teeth.

How do I mould Thermoform Whitening Trays?

Thermoform Whitening Trays can be easily and quickly moulded to your teeth in the comfort of you own home. After you have moulded the thermoform trays to your teeth, you can apply the teeth whitening gel to the trays and wear them for the specified amount of time. Remember to follow the teeth whitening gel instructions carefully to ensure that you achieve the best possible results.

We recommended using our Step-by-Step Instruction Guide, however, the basic tips are as follows:

Heating

Preheat a pot of water to boiling and then remove it from the heat source, immerse the trays in the hot water until they become pliable.

Moulding

Remove the trays from the hot water and let them cool for a few seconds until they are comfortable to handle. Then, place the trays over your teeth and gently bite down to create an impression. Use your fingers to press the trays against your teeth to ensure a precise fit.

Cooling

Once you have made an impression of your teeth, remove the trays from your mouth and place them in a bowl of cold water for a few seconds to set the impression.

Trimming

Use scissors to trim any excess material from the edges of the trays, leaving them with a comfortable and snug fit.
