Frequently Asked Questions
Cold light whitening effects typically last 6-12 months, depending on lifestyle and dietary habits. Regular coffee, tea, wine consumption and smoking may reduce duration. Touch-up treatments every 3-6 months help maintain results. Regular dental hygiene and avoiding staining foods/drinks can extend the whitening effect.
Some patients may experience temporary tooth sensitivity after treatment, which usually subsides within 3-7 days. Using sensitive toothpaste and avoiding hot/cold foods can help manage symptoms. Professional clinics use high-quality whitening agents and protective measures to minimize sensitivity risks. Always inform your dentist of any prior sensitivity history so they can adjust treatment intensity accordingly.
