Why Are My Teeth Yellow Even Though I Brush?

Maintaining a bright, white smile is a goal for many, but sometimes, even with diligent brushing and flossing, teeth can still appear yellow. If you've ever wondered, "Why are my teeth yellow even though I brush?" you're not alone. Many people experience this frustration despite their best efforts at maintaining good oral hygiene. As a dentist in Leichhardt, Dr Berera often encounters patients concerned about tooth discolouration, and there are several reasons why this can happen.

Understanding Tooth Discolouration

Tooth discolouration can be broadly categorised into two types: extrinsic and intrinsic.

• Extrinsic discolouration occurs on the outer surface of the teeth. It is typically caused by external factors such as food, drink, or smoking.

• Intrinsic discolouration happens within the tooth structure itself and is often more challenging to address. This can result from factors like genetics, medication, or ageing.

Common Causes of Yellow Teeth Despite Good Oral Hygiene

If your teeth are yellow even though you brush regularly, several factors could be at play:

1. Staining from Food and Drink

Certain foods and drinks are notorious for staining teeth. Coffee, tea, red wine, and certain acidic foods can contribute to extrinsic staining. These substances contain chromogens—pigments that cling to the enamel, the outermost layer of your teeth, leading to discolouration. Even if you brush after consuming these items, the pigments can still penetrate the enamel over time.

2. Smoking and Tobacco Use

Smoking is one of the leading causes of yellow teeth. Tobacco contains tar and nicotine, both of which can cause significant staining. Tar is naturally dark, and when nicotine is mixed with oxygen, it turns yellow, leading to noticeable stains on the teeth. Even with regular brushing, smokers often struggle with yellow teeth.

3. Thin or Worn Enamel

Your enamel is the protective outer layer of your teeth, and it’s naturally white. However, underneath the enamel is dentin, which is yellowish in colour. If your enamel becomes thin or worn down due to acidic foods, brushing too hard, or natural wear over time, the yellow dentin becomes more visible, making your teeth appear yellow.

4. Genetics

Sometimes, tooth colour is hereditary. If your parents have naturally yellow or darker teeth, you might inherit this trait. Genetics also determine the thickness of your enamel, which can influence how white or yellow your teeth appear.

5. Ageing

As we age, our teeth naturally yellow. Over time, enamel wears away, revealing more of the yellowish dentin beneath. Additionally, the dentin itself may darken with age, contributing to a more yellowed appearance.

6. Medication and Health Conditions

Certain medications and health conditions can cause tooth discolouration. For example, antibiotics like tetracycline can cause intrinsic staining if taken during childhood when teeth are still developing. Similarly, chemotherapy and radiation for cancer treatment can result in discolouration. Some antihistamines, blood pressure medications, and antipsychotic drugs can also have this effect.

7. Poor Oral Hygiene Habits

While brushing regularly is essential, it’s also important to floss and use mouthwash to remove plaque buildup that can lead to discolouration. Inadequate brushing or missing areas, such as along the gumline, can also result in plaque and tartar accumulation, which can make teeth appear yellow.

What Can You Do About Yellow Teeth?

If you’re concerned about yellow teeth, there are several steps you can take to improve their appearance:

• Professional Teeth Whitening: One of the most effective ways to brighten your smile is through professional teeth whitening. In-office treatments provide quick and dramatic results, while take-home kits from your dentist offer convenience with the professional strength needed for effective whitening.

• Avoid Stain-Causing Foods and Drinks: Limiting your intake of foods and beverages that stain your teeth can help prevent further discolouration. When you do consume these items, try to brush your teeth afterward or rinse your mouth with water.

• Quit Smoking: Giving up tobacco not only benefits your overall health but also significantly reduces the staining of your teeth.

• Improve Oral Hygiene: Enhance your brushing technique by using a soft-bristled toothbrush and fluoride toothpaste. Make sure to brush for two minutes twice a day, floss daily, and consider using a whitening mouthwash.

• Regular Dental Visits: Routine check-ups with your dentist in Leichhardt are crucial. Professional cleanings can remove plaque and tartar that regular brushing might miss, helping to keep your teeth looking whiter.
