Ever looked in the mirror and wondered how your teeth got so yellow? Many of us have. Because yellowing can happen gradually, it can easily go overlooked.

Luckily, yellowing teeth are not a sign of a serious medical condition. And while it may be disheartening and confidence-shattering to feel like you’ve lost your best accessory—your bright, white smile—you can get it back.

For starters, be aware of what causes yellowing, and how you can avoid or limit exposure to those things.

REASON #1 You’re Getting Older

Your teeth can also start yellowing as a natural part of the aging process. This happens as the strong, white protective coating on teeth, known as enamel, fades over time because of everyday wear and tear on your teeth.

REASON #2 You’re a Smoker

Tobacco products, from cigarettes and pipe smoke, stain teeth. If you consume these products, your teeth will darken over time.

REASON #3 Your Oral Hygiene Is Lacking

When you do not routinely brush, floss and rinse your mouth to remove plaque build-up and tartar, this can hasten the discolouration of your teeth.

REASON #4 You’re on Medication

Certain medications, such as the antibiotics doxycycline and tetracycline, can darken the teeth of children younger than 8 years old. Some antihistamines, drugs for high blood pressure and antipsychotic medications can also stain adult teeth. Go over any such potential side effects of the medications you are currently, or may start taking, with your physician.

REASON #5 You Have an Illness

A less common cause of tooth discolouration can be either a disease that affects enamel, or the treatment of a disease, such as chemotherapy and/or radiation used to treat cancer. In this case, the discolouration is more of a brownish color.

REASON #6 The Yellow Is in Your Genes

It also may be possible that you inherited enamel that is more yellow than that of other people whose genes differ. If you notice your teeth are more yellow than you’d like, you can fix the issue by using a teeth whitening product, such as the Keeko Botanical Teeth Whitening Pen which has been clinically proven to whiten teeth 5+ shades in 7 days.
