The gel normally expires 12 months after purchase, although some gels may lack an expiration date. If you look at the gel and it looks like it has a hazy color, it has expired and it oxidizes. At this point, it will have no effect on teeth whitening. Most teeth whitening agents are good for about a year after manufacture.
Your dentist may have given it to you soon after receiving it from the manufacturer. However, you may have been in the dentist's office for some time. If the dentist stored it in the refrigerator, the effectiveness of the product may be prolonged. Generally speaking, any exposure to light will affect the potency level of the teeth whitening agent.
When you open it, pay attention to the consistency of the gel. If it appears foggy or white, it's too old. It's probably still safe to use. However, it may not be as effective and provide remarkable results.
When wondering about extending the life of a teeth whitening kit, it's good to keep in mind that this is not a possibility. Unfortunately, there is no way to extend the life of teeth whitening gel. However, by taking proper care to store it safely and avoiding storing it in places with high temperatures, you can maintain the shelf life of the product until its expiration date. We all want a bargain, but watch out for flash sales of teeth whitening kits.
Often, the reason these kits are on sale is because they are close to their expiration date. If you plan to use the product before it expires, you're fine, but if you think it might take a while, don't buy the product. The main ingredient in whitening gel for bleaching is hydrogen peroxide. Over time, hydrogen peroxide converts to water and oxygen.
If you try to use a whitening kit after its expiration date, you will likely only receive gel and water, as oxygen will have leaked out of the package. Oxygen is the key component for teeth whitening. For best whitening results, discard any product you find in your home that has passed its expiration date. Acidic foods break down tooth enamel, making them more porous and more likely to absorb stains from the foods and beverages you eat.
Custom teeth whitening trays will be fine, especially since they've been on your dresser all this time. Since over-the-counter whitening products don't always provide the results you want, you may be tempted to use them more often. When they expire, the hydrogen peroxide they contain breaks down and leaves only water and oxygen, which doesn't whiten teeth. For professional and over-the-counter teeth whitening, the first few days after treatment are the most important.
Some dentists offer free teeth whitening to patients who have a regular dental cleaning appointment. Generic whitening kits may contain the same peroxide active ingredient, but are not tested to ensure effectiveness. Look for this seal of acceptance on your teeth whitening products to ensure their effectiveness or talk to your dentist. Your dentist will also provide you with personalized trays and whitening gel that is suitable for your circumstances.
When buying whitening strips or other over-the-counter products, don't store them in hot areas, such as near vents. Your teeth and gums will first be examined to determine if this is the best time to whiten them or if there are other dental problems that need to be addressed first. You don't need to stop staining food completely, but you should avoid them when you're whitening your teeth. I really didn't need to have my teeth whitened at the time like I had a couple of years ago in my old town.
When your teeth are discolored or stained, your dentist can use professional teeth whitening techniques to improve your smile. .
