If your teeth still appear yellow after whitening, it might be due to enamel erosion. The enamel is the outer layer of your teeth, and when it wears down, the underlying dentin, which is yellow, becomes more visible. Erosion can happen due to acidic foods, aggressive brushing, or conditions like acid reflux.
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.
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.
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.
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.
Dehydrated teeth appear white and chalky. You'll notice this more if you're a mouth breather or have a cold. It's why you may get a white spot on a tooth overnight.
To fix patchy teeth whitening, you can perform spot treatments with a pumice stone and hydrochloric acid. However, you'll want to check with your dentist before taking action. Patchy teeth whitening can be caused by several of these, with dehydration of your tooth enamel's surface being one of them.
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!

The Link Between vitamin D Deficiency and Yellow Teeth
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.
Yellow teeth can regain whiteness through various methods, including good oral hygiene, professional dental cleanings, and teeth-whitening treatments. Stains from coffee, tea, or tobacco can be removed with adequate oral care, while professional procedures like bleaching or laser treatments offer quicker results.
Most People Can Whiten Their Teeth Once a Year
Dentists monitor the risks and only recommend whitening to eligible candidates. Most people can get a full bleaching system every 12-18 months with touch-ups throughout the year.
Yes, whitening strips can be effective on yellow teeth, particularly if the yellowing is due to external factors such as smoking, drinking coffee, tea, or red wine. However, the effectiveness can vary depending on the severity of the staining and the type of whitening strip used.
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. For example, teeth that have less calcium will whiten much faster.
Overly concentrated whitening agents or long treatment times can increase the risk of chemical burns on the gums, leading to blisters and tissue damage.
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.
Damaged Enamel
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.
For about two to six weeks, you can use dentist-recommended whitening toothpaste and brush twice a day. You can use a certified whitening mouthwash which usually takes about three months to produce visible results. Whitening strips are the most compelling in-house treatments that last up to six months.
Teeth that have yellowed with age
Dentin is naturally yellowish and cannot be lightened with teeth whitening products.
While they are extremely popular, many people still question whether or not they actually are effective at whitening teeth. The short answer is yes, they do in fact whiten your teeth over time, but whitening strips are not the best way to whiten your teeth!
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.
Note that if there is not enough enamel to whiten, patient may require extra treatments (such as composite bonding or veneers or ceramic veneers) to achieve desirable results.
Schedule a Follow-Up Consultation and Treatment
If your last whitening treatment didn't provide the desired results, a follow-up session may be all you need. In-office treatments like KöR® Teeth Whitening can be repeated after a few weeks, provided your teeth are healthy enough for a touch-up treatment.
