Some patients have concerns about yellow teeth after Invisalign invisible orthodontic treatment. Here we will discuss the myths and realities that accompany this treatment.
Many patients wonder why their teeth turn yellow. This is one of the most common doubts and the answer is that it is due to several factors.
This dental problem has no major repercussions beyond esthetics, but it can be a real discomfort for some people, preventing them from smiling with confidence.
But don’t worry, this problem can be solved.
How to solve the problem of yellow teeth?
The dental whitening that we apply in our dental clinic in Barcelona is one of the most effective to combat yellow teeth.
For this purpose, we pay close attention to this treatment and divide it into two sessions. In the first one we perform a very complete hygiene and apply a desensitizing treatment.
This contributes to the fact that, once the whitening is finished, the patient does not suffer any peak of dental sensitivity.
Then, our LED lamp allows the professional whitening gel we apply to activate and release its full whitening potential.
Do teeth turn yellow with orthodontics?
Tooth yellowing has nothing to do with orthodontic treatment.
In most cases, the change in tooth color is caused by external factors.
Such as tobacco consumption or eating habits, which may influence the change in tooth color.

What are the foods that stain teeth the most?
The foods most likely to stain teeth are:
- Coffee. It is one of the beverages that causes the most damage to the coloration of teeth, due to its high concentration of chromogens, agents that are responsible for coloring plants and minerals.
- Tea. Tea, especially black tea, is another beverage that can stain teeth. Like red wine, the presence of tannins contributes to staining the teeth.
- Soft drinks and sweetened beverages. Sugary soft drinks, sodas and energy drinks have a high concentration of sugars, which makes them an enemy of teeth, both color and enamel.
- Fruits and vegetables of intense color. Fruits such as blueberries, blackberries or cherries and vegetables such as beets are included in this package.
- Citrus. Care should be taken with citrus fruits as their acidic content may damage the enamel.
- Sauces. Soy sauce, ketchup, mustard, Modena vinegar or turmeric can stain teeth.
Also, poor oral hygiene and tartar accumulation can cause teeth to change their color to a darker shade.
But above all is the patient’s genetics and age. This will determine the shade of the natural white of the teeth and it should be taken into account that with age, the natural dentin is lost.
Another of the most common factors is that the teeth may become yellow due to the consumption of some very aggressive medications.
Can teeth turn yellow from smoking?
The main factor causing tooth discoloration is tobacco.
Daily tobacco use causes the patient’s teeth to turn yellow and contributes to the onset of gum disease.
That is why our dentists in Barcelona strongly recommend not smoking to improve oral health.
Can I wear Invisalign invisible braces if I smoke?
Invisalign invisible braces have great advantages over braces, such as the fact that they can be removed for eating and brushing and are very discreet.
Although smoking is not a precluding element to start an Invisalign treatment, it is highly recommended to give up the habit so that the aligners do not deteriorate during the process.
Can teeth whitening be performed with Invisalign aligners?
Tooth whitening is an independent treatment from orthodontics, but in our dental clinic in Barcelona we recommend applying it once the Invisalign treatment has been completed.
Thus, the patient will be able to wear a perfect smile after both treatments and everything surrounding orthodontic treatment is completed.
In fact, many celebrities with orthodontics have resorted to both treatments to improve the aesthetics of their smile.
In short, tooth color has little or nothing to do with orthodontic treatment. It all depends on the patient’s genetics, daily dental hygiene and whether or not he/she is a smoker.
What we can say without a doubt is that Invisalign orthodontics is the most advanced orthodontic treatment to improve the smile of our patients, whether they are children or adults, who opt for the Invisalign orthodontic system.
