To maintain your teeth whitening results, you need a consistent oral care routine, smart dietary choices, and follow up treatments from your dentist. While professional whitening delivers immediate results, how long they last depends on your habits and maintenance routine.
In this blog, Melbourne dentists share expert strategies to help you make your brighter smile last. We will cover how long teeth whitening typically lasts, which foods and drinks to avoid, and what post whitening care steps can keep your smile looking its best for longer.
How Long Does Teeth Whitening Last?
Quick Answer:
Professional teeth whitening can last from six months to two years, depending on lifestyle factors and oral hygiene.
What Affects Whitening Longevity?
-
Diet: Frequent consumption of coffee, red wine, or dark sauces can lead to staining.
-
Smoking: Tobacco can quickly dull whitening results.
-
Oral Hygiene: Inconsistent brushing and flossing may allow stains to return faster.
-
Type of Treatment: In chair whitening often lasts longer than over the counter methods.
Your dentist may recommend touch up treatments every 6 to 12 months to maintain optimal brightness.

Taking care of your teeth after whitening is essential to protect the results and reduce the risk of sensitivity.
Immediately After Whitening:

Avoid food or drinks that can stain for at least 48 hours.
-
Use a straw when drinking coloured beverages to reduce contact with teeth.

Stick to a white diet for two days, including foods like chicken, rice, cauliflower, yoghurt, and bananas.

Avoid smoking or vaping during this period.
Ongoing Care:

Use a sensitive toothpaste to reduce any post treatment discomfort.

Brush and floss at least twice daily to prevent plaque buildup.

Visit your dentist for regular scale and cleans to remove surface stains.
