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.
This softens tooth enamel and dehydrates it, often causing demineralization in the process. Dehydration is part of the process as the bleaching gel permeates through the enamel of your teeth to reach the dentin layer below, where the staining and discolouration have occurred over time.
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.
To make up for this, most brands, she said, add 'acids and abrasive particles to whiten your teeth'. This results in these products only being effective on the top layer of the teeth. The abrasive particles also lead to a thinning of the top white layer or the enamel, causing the teeth to become yellow over time.
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.
Purple toothpaste works by counteracting yellow discoloration on teeth with purple microparticles so that the teeth appear white temporarily. This interaction, however, does not actually change the internal color of teeth nor remove surface stains.
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.
Saliva is the Best Hydration
Since your teeth are slightly dehydrated after whitening, you may be inclined to drink lots of water. While drinking plenty of water is always a good idea, it won't necessarily rehydrate your teeth. The best way to rehydrate your teeth is by ensuring your mouth stays moist.
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.
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.
However, it's important to understand that your teeth are especially susceptible to discoloration and staining immediately after teeth whitening. Thus, what you do after teeth whitening, especially in the first 48 hours after treatment, determines how well your results will last.
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.
Although teeth whitening is not permanent, it can last for many years. In-office whitening treatments typically last up to 3 years; professional at-home whitening treatment is less long lasting, but it results in much longer-term results than over-the-counter whitening treatments, toothpastes, and whitening strips.
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.
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.
If you are younger than 16, you are not a candidate for teeth whitening. This is because the pulp chamber in young teeth is larger than that of an adult, and whitening treatments could cause irritation. If you are pregnant or lactating, teeth whitening is not recommended.
Many people wonder how to clean stained teeth; fortunately, there are a lot of things you can do to brighten your teeth. A good oral hygiene routine, avoiding stain-causing foods and drinks and using teeth whitening products can help to remove surface stains and brighten your smile.
Hydrogen peroxide is a mild bleach that can help to whiten stained teeth . For optimal whitening, a person can try brushing with a mix of baking soda and hydrogen peroxide for 1–2 minutes twice a day for a week. They should only do this occasionally.
