Can You Use Expired Teeth Whitening Gel?

For best results, you are best off buying a few new teeth whitener gels or teeth bleaching products and using them before their expiration dates. Using expired teeth whitener gels means that you are not going to get the same result of a whitened tooth that you would have had with a new, unexpired teeth whitener gel. By taking the appropriate steps to store the teeth whitening gel safely, and by not placing it somewhere that has a high temperature, it may preserve the product for its life before the expiration date.

The issue is, after its expiration date, the chemicals are no longer effective, meaning that it is useless for you. As far as whitening agents go, there is a chance the bleaching liquid might have a shelf-life date listed on the product. After a set amount of time, usually 2-3 years, all teeth-whitening gels chemically break down and are no longer effective, and if expired, they might not whiten your teeth.

If you are looking to bleach your teeth and you are not comfortable with a messy gel, a bleaching pen might be better for you. Your dentist can adjust your mouth to a custom-made tray, which you fill at home with gel-based bleach. Your dentist will also give you the customized tray and bleaching gels appropriate to your circumstances. Your dentist may be able to make molds of your teeth and create trays specifically designed to whiten them, then provide you with the gel and instructions for using the gel.

A custom whitening tray purchased at a dentist is the recommended method for safely improving your teeth color. When used properly, a quality brand of teeth bleaching strips removes both external and minor internal stains, bleaching teeth to a lighter shade.
Whitening strips may cause some sensitivity, particularly if you have cavities, and should not be used unless you are seeing your dentist every 6 months or have cavities because they can make teeth more sensitive, or they may cause further damage to teeth with cavities. When used improperly or too frequently, they can be unpleasant or damaging to teeth. If you decide to use over-the-counter bleaching strips to bleach teeth, remember these products are designed for healthy mouths. You can prolong the shelf-life of Crests teeth-whitening strips if you store them in your refrigerator since this will keep them fresh and useable for longer.

When you use a free teeth bleaching offer, many dentists will keep providing you with a refill gel that keeps your teeth looking and feeling bright. Free teeth whitening supplies provided by your dentist are designed for use with specialized bleaching trays, which help the gel soak into the teeth, keeping them away from the gums. They are effective in immersing the bleaching products into the teeth uniformly while keeping the gel off your gums.

It is important that you begin with clean teeth to allow the gel to function correctly. Polonight 16 will disperse into your enamel, whitening your teeth uniformly. The bleaching gel is easy to rinse off, so you cannot eat, drink, or rinse off the whitened teeth for approximately one hour after applying.

A lower-strength bleaching gel will work over longer periods, but it also sometimes increases sensitivity due to the time it takes to sit on the teeth for it to produce good results. Whitening gels then become increasingly acidic as they are broken down, which leads to a greater chance of sensitivity and aching. People feel sensitivity to their teeth after whitening because the gel gets into pores on their teeth and changes polarity close to nerves, located at the center of teeth.

The dental bleaching product used is typically Zoom Whitening at most NYC dentist offices, and its formula is changed each time so that it can address this issue of tooth sensitivity. Whitening pens only have an active ingredient that works on teeth for about 30-60 seconds as saliva washes it off, so opt for a whitening pen that uses Hydrogen Peroxide (not carbamide) and is professional-grade gel. You can use desensitizing toothpaste for about 1 month before you bleach your teeth, and you can use either product as long as the sensitivity is reduced.

It is important to speak with your dentist before you decide to have your teeth whitened because whiteners cannot fix every kind of discoloration and they include bleaching agents which, when used improperly, may damage your teeth’ enamel. Each home bleaching kit is different, and you should always follow the manufacturer’s recommendations unless a dentist says otherwise. As far as whitening teeth using at-home kits, these products contain a lower concentration of bleaching agents, which is why it is safer to use them every day for up to three weeks.

At-home bleaching products like strips and gels, or dental office procedures like bleaching in a chair, are some ways that people can brighten their teeth and lessen surface stains. Brushing is done to make sure any plaque — that sticky surface layer on the teeth — is removed, and any bleaching agents in a strip or gel make the closest contact with the teeth. If you attempt to use the whitening kit past the shelf life, chances are that you are getting nothing but gel and water, since oxygen has leaked out of the packaging.

If Hydrogen Peroxide gel is past the best-by date or has expired chemically, you will know immediately as the gel turns to a milky white color, indicating it is already been oxidized and will not work anymore to bleach teeth, and it is harmless. Using a dated, stale, tooth-whitening gel is not helpful, as you are going to waste your time and energy. Using whitening toothpaste over the long haul can help keep your teeth white, but it does not make drastic differences in the color guide.
