Darkening or relapse of the tooth shade is expected after whitening. Relapse of shade occurs almost immediately as the freshly whitened dehydrated tooth rehydrates. Repetitive prolonged exposure of the chemical is the only way to achieve optimal results.
Uneven color post-whitening can result from the bleach reacting differently across your teeth due to variations in enamel thickness and mineral content. This usually evens out with time and proper oral hygiene.
If you find your teeth getting more yellow even after whitening, it may also be because of damage to the enamel. The dentin within your teeth has a yellow hue, and as the enamel wears away, it can expose the dentin and cause discoloration.
Genetics – Genetics can cause some teeth to have a darker color naturally and to be more resistant to whitening. Dental Restorations – Restorative dental work, like crowns, areas with dental bonding, and fillings, won't respond to teeth whitening treatments in the same way as natural enamel.
If teeth whitening does not work for you, it might be because of the product you are using, the type of tooth stains or spots, or strength of the bleaching gel. Product type – Whitening toothpaste does not remove deeply embedded stains.
It is advisable to see your dentist, who will check what the issue may be. Usually, the first thing to try is continuing with the whitening. Usually, you just need an extra syringe or two of gel to achieve a good result. The other check the dentist will make at this stage is the fit of your whitening trays.
If you experience teeth translucency after teeth whitening, don't panic! This relatively common side effect usually subsides within a few weeks. To prevent this, use safe and gentle teeth whitening solutions or discuss options with your dentist to ensure a lasting result without the risk of enamel damage.
The natural color of teeth can vary due to various factors, including genetics, age, and lifestyle habits. Some individuals naturally have teeth that are darker or have a yellowish tint. These teeth may have a denser enamel layer or more pigmented dentin, making them more resistant to whitening treatments.
Teeth Are Not Clean
The chemicals break down the stain molecules that cause teeth to darken. Plaque buildup can block these whitening chemicals from reaching the stained teeth. Schedule a dental cleaning appointment first before using teeth whitening strips. This can prepare your teeth well for the whitening process.
The center of your tooth has more enamel than the outside, so it takes longer to show results. Some teeth may appear to be whiter than others because each tooth responds differently to bleaching. The composition and structure of teeth affect how they react to bleaching.
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.
Intrinsic stains, which are caused by medications or aging, can be especially tough to remove. Teeth whitening treatments may not work if your teeth have this type of discoloration. Extrinsic stains, caused by foods and drinks, can usually be removed with teeth whitening treatments.
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.
Some home kits don't contain enough whitening product to be effective. Also, if a dental professional isn't doing the whitening, the mouthguard provided may not fit properly so some of the bleaching gel may leak out onto your gums and into your mouth, causing blistering and sensitivity.
Why Did Your Tooth Turn Gray After Whitening It? There are several things to consider: It may be that your tooth was damaged before you applied the whitening gel to it, and it became irritated afterward. The problem might stem from the whitening gel.
If used over time and without the aid of a professional cosmetic dentist, this treatment could cause tooth sensitivity and at times pain. The worst part for these patients is that by affecting the enamel and causing teeth to become more sensitive overall, the teeth are then primed to become even more stained over time!
Factors Affecting the Longevity of Whitening
Several factors determine how long your teeth stay white, including the type of treatment, your lifestyle, and your oral care routine. Foods and drinks like coffee, wine, and berries can cause staining, while smoking can lead to yellowing of the teeth.
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.
Too much plaque and tartar
Plaque is a sticky substance created by the bacteria in your mouth. Brushing and flossing removes plaque from your teeth. If you don't brush your teeth before applying the whitening strips, the sticky plaque may block the stain-fighting chemicals from reaching your teeth.
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.
Poor oral hygiene: If you have poor oral hygiene habits, such as not brushing or flossing regularly, this can result in surface stains that are harder to remove with teeth whitening treatments.
While there are several risks associated with teeth whitening, the procedure is generally safe when done by a professional. They are trained and certified and know how to apply the bleaching agents properly and how long to leave them on your teeth.
As these agents work to eliminate stains, they also extract moisture from the enamel, causing a temporary loss of water content. This dehydration leaves behind a porous and less mineralized surface, causing white spots on teeth after whitening.
Depending on the severity of your enamel loss, you may consider more cosmetic treatments for translucent teeth. Bonding and veneers are great ways to get your bright smile back. Bonding is a fast and minimally invasive cosmetic treatment that can restore the original look of your teeth in a single appointment.
Does tooth enamel grow back? No, if your enamel is completely gone, you can't bring it back. But your dentist can place a dental crown over your tooth to protect it from further damage.
