o maintain your results, avoid consuming foods and drinks that can stain your teeth for at least 24 hours after treatment. This includes coffee, tea, soda, wine, and cigarettes. Additionally, brush your teeth twice a day and floss daily to remove plaque buildup, which can contribute to staining.

The longevity of your whitening results varies depending on factors such as diet, oral hygiene, and lifestyle. On average, teeth whitening can last 6 months to 2 years. To extend the results, avoid stain-causing foods and drinks, and maintain a good oral hygiene routine.

After whitening, your tooth enamel is more porous for about 24–48 hours. During this time, your teeth are more susceptible to staining, so it’s essential to avoid foods and drinks that could cause discoloration. Over time, your enamel will re-harden and the pores will close, making your teeth less prone to staining.

Teeth may appear yellow after whitening for a few reasons:

• Post-treatment sensitivity: Some people experience a temporary yellowish appearance as the enamel recovers from the whitening process.
• Dietary habits: If you consume dark foods or beverages (like coffee or red wine) immediately after whitening, your teeth may stain more quickly.
• Natural tooth color: Your natural tooth color may also influence how the whitening treatment works, especially if your teeth were very dark or stained before the treatment.
• Improper aftercare: Not following post-whitening care instructions, such as avoiding staining foods, can lead to discoloration.

If you notice yellowing despite following care guidelines, a follow-up treatment or touch-up may be necessary.

Use white toothpastes and clear mouthwashes – Avoid colored toothpastes and mouthwashes as they could prematurely stain your teeth. Rinse your mouth with water – If you do happen to eat or drink something that could stain your teeth, you can thoroughly rinse your mouth with water to help remove the residual particles.
