Why are my teeth yellow when I brush them everyday?


Maintaining good oral hygiene is essential for overall dental health. Brushing your teeth twice a day is a common practice, but sometimes even with regular brushing, you may notice that your teeth appear yellow. This article explores the various reasons why your teeth may be turning yellow despite your daily brushing routine. We will delve into common causes, preventive measures, and effective treatments to restore your pearly white smile.

Factors contributing to yellow teeth:

1. Diet and staining foods:

Your diet plays a significant role in the color of your teeth. Consuming staining foods and beverages like coffee, tea, red wine, and dark-colored fruits can gradually discolor the enamel. These substances contain chromogens, which are highly pigmented molecules that cling to the teeth. Additionally, acidic foods like citrus fruits and sodas can erode the enamel, making the teeth more susceptible to staining.

2. Poor oral hygiene:

While you brush your teeth regularly, it's equally important to maintain proper oral hygiene practices. Inadequate brushing technique, inadequate brushing time, or neglecting to floss and rinse your mouth properly can leave behind plaque and tartar. Plaque build-up, when left unattended, can cause yellowing of the teeth.

3. Tobacco use:

Smoking or chewing tobacco products can significantly contribute to yellowing teeth. The chemicals in tobacco, such as nicotine and tar, not only turn the teeth yellow but can also lead to stubborn stains that are challenging to remove. In addition to staining, tobacco usage can increase the risk of oral cancer and various other dental problems.

4. Age-related factors:

As we age, the enamel on our teeth tends to wear down gradually, exposing the underlying dentin layer, which is naturally yellow in color. Therefore, even if you maintain good oral hygiene, your teeth may appear yellowish due to the natural aging process.

5. Medications:

Certain medications, such as antibiotics like tetracycline and doxycycline, can cause tooth discoloration when consumed during tooth development stages, especially in children under the age of 8. Other medications like antihistamines, high blood pressure drugs, and antipsychotic drugs can also contribute to yellowing teeth as a side effect.

Preventive measures for yellow teeth:

1. Brushing technique:

Ensure you brush your teeth correctly to remove plaque effectively. Use a soft-bristled toothbrush and fluoride toothpaste and brush gently in circular motions. Avoid applying excessive force as it can erode the enamel and cause gum recession.

2. Regular flossing:

Flossing helps remove food particles and plaque from hard-to-reach areas between teeth and along the gum line. Daily flossing complements regular brushing and significantly reduces the chances of yellowing teeth.

3. Limit staining foods and beverages:

Be mindful of your diet and limit consumption of staining foods and beverages. If consumed, rinse your mouth immediately afterward or brush your teeth if possible. Drinking through a straw can also help minimize contact between these substances and your teeth.

4. Quit smoking or chewing tobacco:

Apart from the numerous health benefits, quitting tobacco will prevent further yellowing of your teeth and improve your overall dental health. Consult a healthcare professional or join a support group if you need assistance in quitting.

5. Regular dental cleanings:

Schedule routine dental cleanings with your dentist. Professional cleanings help remove stubborn plaque and tartar buildup that cannot be eliminated by regular brushing and flossing alone. These cleanings not only maintain your dental health but also contribute to a brighter smile.

Effective treatments for yellow teeth:

1. Professional teeth whitening:

Professional teeth whitening treatments can be a game-changer for yellow teeth. In-office whitening procedures performed by a dentist use strong bleaching agents to enhance the natural whiteness of your teeth. This treatment yields immediate results and can dramatically lighten the shade of your teeth.

2. Dental veneers:

Dental veneers are thin, custom-made shells that cover the front surface of teeth to improve their appearance. Veneers are an effective option for severe tooth discoloration that cannot be treated with whitening alone. They provide a long-lasting solution, creating a natural-looking, white smile.

3. Composite bonding:

Composite bonding involves applying a tooth-colored resin material to the tooth surface to mask discoloration and reshape the teeth. This treatment not only improves the color but also repairs minor chips and cracks, providing a uniform and aesthetically pleasing smile.

4. Dental crowns:

For severely discolored teeth that cannot be treated with whitening or bonding, dental crowns (caps) may be recommended. Crowns completely cover the affected tooth, restoring its shape, size, strength, and improving its appearance.

5. Lifestyle modifications:

Maintain a healthy lifestyle, which includes proper oral care, a balanced diet, and limiting staining substances. By making these lifestyle changes, you can prevent further discoloration and extend the longevity of any cosmetic treatments you undergo.


Despite regular brushing, several factors can contribute to yellowing teeth. A combination of preventive measures along with professional dental treatments can help restore the natural whiteness of your teeth and enhance your smile. Consult with a dentist to determine the best treatment options suitable for your individual needs. Remember, a beautiful smile goes beyond brushing alone!
