Teeth whitening products are designed to help reduce the appearance of surface stains. Ingredients such as hydrogen peroxide or carbamide peroxide release oxygen molecules that interact with discolored compounds, which can make teeth look brighter.

The duration varies depending on the product and individual use. Whitening strips are typically used over a period of 1–2 weeks, while gels are often applied for shorter treatment cycles. Toothpaste and mouthwash are best suited to help maintain the overall effect.

• Whitening strips – easy to apply, commonly used in short treatment cycles
  
• Whitening gel – designed for more intensive applications
  
• Whitening toothpaste – supports a brighter-looking smile with regular use
  
• Whitening mouthwash – helps maintain freshness and complement other whitening routines

Some people may experience temporary sensitivity during whitening. To help manage this, you can:

• Use a toothpaste formulated for sensitive teeth
  
• Reduce how often you use whitening products
  
• Avoid very hot or cold drinks for a short period

The choice depends on your preferences and daily care goals:

• Whitening toothpaste – helps reduce surface stains for a brighter-looking smile
  
• Sensitive toothpaste – formulated for people with sensitive teeth
  
• Fluoride toothpaste – supports enamel care as part of daily hygiene
  
• Herbal toothpaste – made with natural ingredients for gentle everyday use

Most dental professionals recommend replacing your toothbrush about every 3 months, or sooner if the bristles look worn.

Brushing helps clean the surface of your teeth, but it doesn’t always reach between them. Flossing is commonly recommended as part of daily oral care to help keep those spaces clean.

If you notice occasional gum bleeding, you may want to:

• Brush gently with a soft-bristled toothbrush
  
• Keep up with daily flossing and rinsing
  
• Visit your dentist for professional advice if the problem continues

• Brush your teeth, tongue, and gums regularly
  
• Use a mouthwash to help freshen your breath
  
• Drink plenty of water throughout the day
  
• Chew sugar-free gum between meals

Teeth whitening products are formulated to be safe when used as directed. Some people may experience temporary sensitivity if products are overused, which is why it’s important to follow the instructions carefully.
