What Causes Yellow Teeth and How Does Teeth Whitening Help

There are various causes of yellow teeth, and most of them relate to lifestyle choices.

Regardless of the cause of your tooth discolouration, teeth whitening is an effective way to bleach yellow teeth and give you a smile to be proud of.

This post will explore ‘what causes yellow teeth’ and how teeth whitening can restore your smile.

What Causes Yellow Teeth?

Ageing

It’s common to develop yellow teeth as you age because your enamel gets thinner, exposing the dentin below it.

Dentin darkens as we age, and as it becomes more visible, it exacerbates the discoloured teeth’ appearance.

Poor dental hygiene practices

Not brushing and flossing often enough, coupled with a build-up of surface plaque and tartar, also contributes to the appearance of yellow teeth.

Getting a professional dental clean will remove many surface stains and any plaque and tartar, instantly improving your smile’s appearance, but more stubborn stains may require teeth whitening.

Smoking

Smoking is a significant contributor to yellow teeth. Nicotine and tar stain the teeth, and these stains often become deeply embedded in the enamel.

Unfortunately, brushing alone usually won’t remove tobacco-related staining, making professional teeth whitening one of the few ways to regain a cleaner, brighter look.

Different beverages

Dark beverages such as tea, coffee, red wine, and cola often cause tooth discolouration. These drinks contain chromogens, pigments that adhere to tooth enamel and gradually darken it.

If you regularly consume these drinks, it’s not surprising that you may wonder what causes yellow teeth. Limiting their intake or rinsing their mouth afterwards can help, but teeth whitening may still be needed to brighten their smile.

Genetics

Some people have whiter teeth than others. This is often due to thicker dental enamel covering the teeth, which disguises the yellow dentin below it.

Certain medicines

Several different medicines contribute to tooth discolouration. Certain antidepressants, antibiotics, antihistamines, and blood pressure medicines may also cause yellow teeth.

Trauma

Trauma can affect the developing teeth in children and result in discolouration in adults’ and kids’ teeth. If the dental enamel is cracked or chipped, it can cause your teeth to discolour.

How Professional Teeth Whitening Treatments Can Help Yellow Teeth

Professional teeth-whitening procedures aim to safely and effectively remove stains and brighten teeth.

While whitening toothpastes and over-the-counter kits may offer minor results, nothing compares to the precision and strength of an in-office procedure.

Step 1: Consultation and Evaluation

Your Auburn dentist will start with a consultation to understand your goals and check the overall health of your teeth and gums.

This is a crucial step to rule out any conditions, such as decay or gum disease, that need to be treated before whitening.

Step 2: The Whitening Process

During the procedure, your Auburn dentist will apply a whitening gel containing high hydrogen peroxide concentrations.

This ingredient works by breaking down stain molecules on and within the enamel. Often, the gel is activated with a special blue light to enhance its effectiveness.

The treatment is usually repeated two to three times in one session and can significantly brighten your smile in under an hour.

Step 3: Post-Treatment Results

Most patients see a noticeable improvement after a professional teeth whitening treatment, often several shades lighter. The results are immediate, and a brighter smile can last from 12 to 18 months with good care.

Is Teeth Bleaching A Safe Method To Treat Yellow Teeth?

Yes, teeth whitening is safe and noninvasive when performed by a qualified dentist. Your Auburn dentist will protect your gums and soft tissues during the process and choose the correct strength of whitening agent for your teeth.

This approach ensures effective results while minimising sensitivity and risk.

Be cautious with at-home remedies and unregulated products, which can sometimes damage enamel or irritate gums. Professional treatments provide peace of mind and a noticeably brighter smile without the guesswork.
