Wondering how teeth get stained? There are a number of factors and causes.
Types of Staining
There are three different types of tooth staining: intrinsic, extrinsic, and age-related.
Intrinsic Tooth Staining
Intrinsic staining is when the stain is the result of something happening inside the tooth. Intrinsic stains usually appear greyish in colour and are resistant to over-the-counter whitening products. Common causes of intrinsic staining include tooth decay, tooth trauma or injury, certain medications, or exposure to too much fluoride.
Extrinsic Tooth Staining
Extrinsic staining is when the stains are only on the tooth enamel, not the inner part of the tooth. These types of stains are easier to get rid of. Common causes of extrinsic tooth stains include tobacco use and consuming certain foods and beverages.
Age-Related Tooth Staining
As we age, our tooth enamel naturally wears away, resulting in a yellowish discoloration of the teeth. Talk to your dentist about the best ways to strengthen your enamel as you age.
Common Causes of Tooth Discolouration
Tobacco Use
Smoking cigarettes and using other tobacco products such as chewing tobacco is a very common cause of noticeable tooth staining.
Poor Dental Hygiene
A poor dental hygiene routine will result in a buildup of plaque and yellowish staining of the teeth. To prevent this, brush your teeth at least twice a day, floss once a day, and visit your dentist for regular checkups.
Certain Medications
Some medications, including certain antibiotics, can result in tooth staining.
Diet
Specific foods and beverages can trigger tooth staining. Foods with dark pigments, tannins, or high levels of acidity are the most likely to cause staining. The following are some of the most common dietary causes of stained teeth:
- Coffee
- Tea
- Red wine
- Tomato-based sauces
- Blueberries
- Blackberries
- Cola
- Soy sauce
- Balsamic vinegar
