Why tooth colour changes over time
It’s natural for teeth to darken or become discoloured as we age. Everyday habits like drinking tea, coffee, or red wine, as well as smoking, can cause staining. Certain medications or dental trauma can also affect tooth colour.
While there are many ways to whiten teeth, not all methods are safe or effective. Understanding your options can help you achieve a brighter smile without damaging your enamel or gums.
What causes stains on teeth
There are two main types of tooth staining:
- Extrinsic stains: Affect the outer layer of the tooth (enamel) and are often caused by food, drinks, or smoking.
- Intrinsic stains: Occur inside the tooth, often due to ageing, medication, or excessive fluoride exposure.
Both can make your smile look dull, but safe whitening treatments can help remove or lighten these stains with the right care.
Safe ways to whiten your teeth
For safe and effective results, follow these steps:
- See your dentist first to discuss the best whitening options for your teeth.
- Use dentist-approved whitening products, such as gels, trays, or strips that contain regulated levels of peroxide.
- Avoid unregulated online kits or home remedies like baking soda or lemon juice, which can damage enamel.
-
Maintain good oral hygiene to prevent new stains and prolong whitening results.
Your dentist may also recommend professional whitening treatment for longer-lasting, more even results.
Daily habits that keep teeth brighter
Whitening works best when paired with a consistent cleaning routine. Brush twice a day with a fluoride toothpaste, limit stain-causing foods, and rinse your mouth after drinking coffee, tea, or wine.
Cleaning between teeth is just as important, as plaque build-up can trap stains and make teeth appear dull. A Waterpik™ water flosser helps remove debris and plaque from between teeth and below the gumline, making your smile appear cleaner and brighter.
How water flossing supports a whiter smile
The water flosser uses a gentle stream of pulsating water to wash away food particles and plaque that brushing alone can miss. It helps keep your teeth clean, your gums healthy, and your mouth feeling fresh.
By reducing plaque and bacteria, it also helps prevent discolouration caused by buildup along the gumline. Consistent water flossing supports a brighter, healthier smile naturally.
Keep your smile healthy and bright
Whitening your teeth safely starts with good daily care. By combining professional advice, healthy habits, and effective cleaning tools like a water flosser, you can enjoy a brighter, more confident smile without harming your enamel.
