Why Do Redheads Have Yellow Teeth? Decoding the Mystery Behind Redheads

Red hair and its unique characteristics can be quite intriguing. From the fiery personality that typically comes with redheads to their sometimes delicate skin, there are several things that make these individuals stand out from the crowd. One characteristic that has puzzled many, however, is the fact that many redheads seem to have yellow or discolored teeth. But why is this the case? Do redheads just naturally have poorer dental hygiene than others? In this article, we’ll dive into the science behind why redheads seem to be more prone to yellow teeth.

1. Genetics

One of the main reasons why redheads tend to have yellow teeth is due to genetics. Redheads have a mutation in their MC1R gene that causes the body to produce more pheomelanin than eumelanin. Pheomelanin is a pigment that gives redheads their hair color, but it also affects the color of their skin and teeth. Pheomelanin can make teeth appear more yellow because it reflects less light than eumelanin does. Essentially, the more pheomelanin a person has in their body, the more yellow their teeth may appear.

2. Thin Enamel

Another reason why redheads may have yellow teeth is due to their enamel. Enamel is the outer layer of the tooth, and it’s responsible for protecting teeth from decay and damage. Redheads tend to have thinner enamel than individuals with other hair colors, which can make teeth look more yellow. Thinner enamel also makes teeth more susceptible to damage and staining, which can further contribute to yellowing teeth.

3. Diet

Diet can play a role in the color of a person’s teeth as well. Redheads, in particular, should be cautious about consuming certain foods and beverages that could contribute to yellow teeth. Foods and drinks that are high in acid, such as citrus fruits and carbonated drinks, can wear away at tooth enamel and lead to yellowing. Darkly pigmented foods such as beets, berries, and tomato sauce can also stain teeth and make them appear yellow.

4. Smoking

Smoking is another significant factor that can contribute to yellow teeth. Redheads who smoke or use tobacco products are at a higher risk of having yellow teeth due to the nicotine and tar in cigarettes. Smoking can also cause gums to recede, which can make teeth appear longer and more yellow than they actually are.

5. Poor Oral Hygiene

Lastly, just as with anyone else, poor oral hygiene can also lead to yellow teeth in redheads. Inadequate brushing and flossing can lead to plaque buildup and teeth stains, leaving them discolored. Visiting the dentist twice a year for cleanings and checkups is essential, as professional teeth cleaning can remove plaque and tartar buildup that brushing alone may not be able to remove.

Frequently Asked Questions

If you are a redhead, you may have noticed that your teeth look more yellow than those of your non-redhead friends. This is a common occurrence, and many people wonder why it happens. Here are some frequently asked questions about why redheads have yellow teeth:

Is it true that all redheads have yellow teeth?

No, not all redheads have yellow teeth. The yellowing of teeth is more common in natural redheads, but it can also occur in people with other hair colors. It depends on the thickness of the enamel on your teeth and how much dentin is visible.

Can you prevent the yellowing of teeth if you are a redhead?

Yes, you can take steps to prevent yellowing of teeth. One way is to practice good oral hygiene, such as brushing your teeth twice a day, flossing daily, and using mouthwash. You can also avoid foods and drinks that stain your teeth, such as coffee, tea, and red wine. If you are a smoker, quitting smoking can also help prevent the yellowing of teeth.

How can you whiten yellow teeth?

If your teeth are already yellow, there are several ways to whiten them. You can try over-the-counter whitening products, such as whitening toothpaste or strips. You can also visit your dentist for professional teeth whitening treatments, such as bleaching or laser whitening. However, it’s important to note that whitening treatments may not be as effective for redheads because of their thinner enamel.

Are there any health risks associated with yellow teeth?

Yellow teeth themselves are not a health risk, but they can be a sign of poor oral hygiene. If you don’t brush and floss regularly, plaque can build up on your teeth and gums, which can lead to tooth decay and gum disease. It’s important to take care of your teeth and gums to prevent these conditions.


In conclusion, yellow teeth in redheads are not entirely preventable. It’s all about genetics, diet, and lifestyle choices. Knowing the causes of yellow teeth in redheads can help individuals take proactive measures to keep their teeth healthy and looking their best. By staying on top of oral hygiene, avoiding acidic foods and smoking, and keeping regular dental appointments, redheads can maintain a healthy, bright smile regardless of the amount of pheomelanin in their system. As with anyone else, good oral care habits are crucial in maintaining healthy teeth and a bright smile.
