As an adult, you are not immune to dental problems. In addition to maintaining a good home care routine, the best thing you can do is to schedule regular dental checkups and professional cleanings. You also have a variety of cosmetic options available, including orthodontics (braces), whitening (both in-office and at-home) and bonding (veneers).


  • As the enamel on teeth wears, the yellowish dentin underneath starts to show through.
  • As people age, their teeth will naturally become slightly discoloured
  • An easy way of reducing discolouration of the teeth is to brush them frequently.

 All dentists agree: "The No. 1 cause of yellow teeth is lifestyle". Smoking, drinking coffees and teas, and chewing tobacco are the worst offenders."

 Let's look at some of the factors:


As a rule of thumb, any food or drink that can stain clothes can also stain your teeth, that's why dark-coloured foods and beverages, including red wine, fizzy drinks, chocolate and dark sauces — such as soy sauce, balsamic vinegar, tomato sauce and curries — can discolour teeth. In addition, some fruits and vegetables — such as grapes, blueberries, cherries, beets and pomegranates — have the potential to stain teeth.

➡️Poor Hygiene

 Poor oral hygiene is one of the causes of yellow teeth, but even the most diligent brushers and flossers can develop the discoloured teeth that occur simply with age.


 Smoking is one of the top causes of yellow teeth, and stains from smoking can be stubborn. The tar and nicotine in tobacco are chemicals that can cause yellowish stains on the surface of teeth, but smokers can improve their yellow teeth by quitting smoking, following a complete oral care routine of twice-daily toothbrushing and daily flossing, and using the right teeth-whitening products.

➡️Intrinsic stains

Intrinsic stains occur within the inner structure of the tooth, called the dentin, making these stains more difficult to remove. Numerous medications can cause intrinsic stains on teeth. If children take the antibiotics tetracycline or doxycycline while their teeth are still developing (before the age of 8), their teeth may turn brownish-yellow.

➡️How to whiten yellow teeth:

If you want to whiten yellow teeth, it’s hard to know where to start. There are so many options available to whiten yellow teeth that it can get overwhelming. No matter what you decide, it's always a good idea to ask your dentist about a whitening program. Brushing, professional cleaning, whitening treatments and veneers should be your go-to solutions for yellow teeth. Here are the most common:

  • Professional Teeth Whitening

Professional teeth whitening is done at your dentist’s office and includes the application of a bleaching agent directly to your teeth. Special lights or lasers may also be used to enhance the performance of the bleach. Depending on the condition of your yellow teeth, you may have one or several treatments that range from approximately 30 minutes to an hour.

  • At-Home Teeth Whitening

These options are more economical. At-home teeth-whitening options include whitening toothpastes & powders, whitening strips & whitening kits. Initial results are typically seen in just a few days and last for up to twelve months.

With so many options available for whitening discoloured teeth, there's no reason to feel embarrassed about their colour. If you can't fix the problem at home, your dentist would be happy to provide further guidance.
