Tooth Stains 101: What Causes Them and How to Get Your Brightest Smile Back!

We all want a bright, white smile, but sometimes tooth stains sneak in and make our pearly whites look a little less…well, pearly! Tooth stains come in various forms and shades, each with its own causes and treatments. So, if you're wondering why your teeth aren't as bright as they used to be, here's a quick guide to understanding the types of stain and how to get your sparkle back!

Our dentists in Teddington can help tackle tooth stains so don't hesitate to book your next appointment. 

The Three Main Types of Tooth Stains

Tooth discolouration generally falls into three categories: extrinsic, intrinsic, and age-related stains. Each type has its own causes and treatment options, so let's dive in to find out more.

Extrinsic Stains

Extrinsic stains are the most common type of tooth stain. They occur on the outer surface of the teeth, affecting the enamel, and are typically caused by what you eat, drink, or inhale.

Causes of Extrinsic Stains:

• Foods and Drinks: Coffee, tea, red wine, and even certain fruits (like berries) are notorious for staining teeth. The pigments in these foods and drinks can cling to the enamel, leaving a dull, discoloured appearance.
• Tobacco: Smoking or chewing tobacco can cause deep yellow or brown stains on the enamel.

Treatment for Extrinsic Stains:

Extrinsic stains are often easier to remove than other types. Regular brushing and flossing can help prevent these stains, and professional cleanings with your Church Road dentists in Teddington can often remove or lighten them. For more stubborn stains, teeth whitening treatments can work wonders, lifting those surface stains and restoring a whiter smile.

Intrinsic Stains

Intrinsic stains are deeper, forming within the tooth itself, and are usually more difficult to remove than extrinsic stains. These types of stains can be caused by factors that affect the tooth's development or internal structure.

Causes of Intrinsic Stains:

• Medications: Certain medications, like tetracycline antibiotics, can cause discolouration if taken while teeth are still developing.
• Excessive Fluoride: Consuming too much fluoride during childhood can cause white or brown discolouration, known as dental fluorosis.
• Trauma: Injury to a tooth can damage the inner tissue and cause it to darken or discolour over time.

Treatment for Intrinsic Stains:

Because intrinsic stains are located within the tooth, they can be more challenging to treat. Professional whitening treatments may help to some extent, but in many cases, dental bonding or veneers might be recommended by your dentist at Church Road Dental Care Centre in Teddington to cover the discolouration and restore a natural look.

Age-Related Stains

Age-related discolouration is a natural part of the ageing process. Over time, the outer enamel layer on our teeth thins, revealing more of the yellowish dentin underneath. This can make teeth appear darker or more yellow, even if they're healthy. Years of chewing, brushing, and exposure to foods and drinks can cause enamel to thin, making stains more noticeable.

Treatment for Age-Related Stains:

Whitening treatments can help, but because age-related stains are also linked to enamel thinning, your Teddington dentist may suggest options like veneers to give your smile a refreshed look.
