Teeth can become temporarily dehydrated after using whitening strips. Your teeth may appear more yellow as a result of this dehydration because the enamel may become dry and lack moisture. Dehydrated enamel sometimes has a transparent appearance that makes the naturally yellowish dentin underneath visible.
Whitening strips often contain peroxide-based chemicals to eliminate enamel stains, which may lead to temporary irritation and redness of the gums. This redness creates a visual contrast that can make the teeth seem more yellow.

Over whitening your teeth can cause them to become translucent, making the yellowish colour of your dentin more visible. It can also make your teeth look blue or grey. To avoid this occurrence, talk to your dentist about how often you should whiten your teeth and what concentration of bleaching agent is right for you.
Foods and drinks with strong pigments, such as coffee, tea, red wine, and some fruits like berries, can reverse the effects of teeth whitening by staining your teeth. Consuming these in moderation and practicing good oral hygiene can help maintain whitening results.
The myth that teeth whitening will make your teeth more susceptible to staining is mostly untrue. In the first couple days after whitening, you must avoid foods and beverages with dark pigments, such as coffee and berries. After the pores in your enamel close, your teeth will retain their newly whitened color.
The most common cause of uneven color after teeth whitening is the uneven application of products used. This can happen with the bleaching gel at your professional dentist and the peroxide solution in your at-home teeth whitening kits. In some cases, this can be a fault of the product.
What are the risks of teeth whitening? No matter what treatment you use, there's a chance your gums will be sensitive to the chemicals used in teeth whitening, particularly if you already have sensitive teeth. There's also a chance of burns to gums and some of the whitening kits used at home can harm tooth enamel.
There are two ways that yellow teeth can be whitened: mechanical whitening methods and chemical whitening methods. Mechanical whitening methods include brushing with whitening toothpastes that include whitening agents that work as abrasives to polish away surface stains.
Now, the big concern: do teeth go back to their original colour after whitening? The answer is that they can, but not immediately and only sometimes wholly. Gradual Fading: Over time, the whitening effects can fade.
Teeth that have yellowed with age
Dentin is naturally yellowish and cannot be lightened with teeth whitening products.
The pores slowly close over the next two to three days, but during that time, your teeth are more susceptible to staining from foods and drinks. For at least the first 48 hours, it's best to avoid darkly colored foods and drinks, including berries, coffee, tea, red wine, and tomato sauce.
With time, these tannins cling to your teeth's enamel and create yellowish stains. Similar to this, frequent use of tobacco products or cigarette smoking might cause your teeth to remain yellow even after whitening procedures.
You may not see it, but your teeth may have a dirty biofilm or layer of plaque buildup that is preventing the whitening agents from targeting your tooth stains. Consider teeth whitening after your next routine dental cleaning.
Diet plays a significant role in the color of our teeth, and certain dietary choices can contribute to yellowing over time. Foods and beverages that are highly pigmented, such as coffee, tea, red wine, dark berries, and some sauces, contain chromogens, which are compounds known to cause staining on tooth enamel.
We do not recommend using Crest 3D Whitestrips on your back teeth because the strips are specially designed to fit front teeth — the teeth shown when you smile. If you use Whitestrips on the back teeth, the strips may become loose and eventually fall off during the wear period as a result.
The fastest and best way to whiten teeth at home is by using professional whitening gel trays.

Increased Susceptibility to Cavities: Weak enamel due to insufficient calcium absorption increases the risk of cavities. Decayed areas can appear yellow or brown, contributing to an overall discolored smile.
The intrinsic type of yellow staining is tightly bonded to the organic matrix of your enamel and will not be removed by brushing alone. They are harder to eliminate, so brushing with whitening toothpaste would have negligible effect. Much more is required to remove these stains.
Teeth whitening isn't for children under 16. It's also not for pregnant or lactating women. Or, for people with allergies or sensitivities. It's also not for those with lots of dental work, gum disease, or tooth decay.
The Importance of Aftercare. In the days and weeks following your treatment, your new, whiter teeth are more susceptible to staining. That's because the whitening process opens the pores in your tooth enamel, making them more receptive to colors from foods and drinks.

Whether you're using commercial whitening strips or an at-home kit from your dentist, most dental professionals recommend touching up every 3-4 months or after every time you have your teeth cleaned. Typically, you only have to wear the kit 3-4 times to “boost” your smile back to its whiter color.
By gently coating your teeth with a product like MI Paste or Colgate's Pro-Argin Toothpaste, you will plug up open pores on your teeth and reduce sensitivity. Additionally, the remineralizing effects of these pastes help to improve whitening.
