In-Chair Whitening vs Take-Home Kits: Which Is Better?

What is In-Chair Whitening?

• Immediate results, often in under an hour
• Dentist supervision to reduce sensitivity
• Stronger whitening agents (up to 6% hydrogen peroxide in Australia)
• Application of protective agents to safeguard enamel and gums

What is a Take-Home Whitening Kit?

• Whitening takes place gradually
• Lower peroxide concentration
• Custom trays ensure even application
• Ideal for sensitive teeth or ongoing maintenance

Whitening Results: What to Expect

• In-chair whitening can last 12 to 24 months
• Take-home kits usually maintain results for 6 to 12 months
• Avoiding coffee, wine, smoking, and coloured foods helps extend results
• Occasional top-up treatments may be needed every 6 to 12 months

Which Is Safer for Sensitive Teeth?

• In-chair whitening may cause temporary sensitivity due to higher peroxide strength
• Take-home kits offer more control and are typically better for patients with existing sensitivity
• Dentists at Leederville Dental can apply desensitising agents before and after treatment to minimise discomfort

When is In-Chair Whitening More Suitable?

• You want instant results before a wedding, job interview, or special event
• You prefer having everything handled by your dentist
• You have limited time and need quick whitening in a single appointment

When is a Take-Home Kit a Better Option?

• You prefer a gradual change over several days
• You’re managing tooth sensitivity
• You’re looking for a more affordable option
• You want to maintain whitening results long-term with occasional touch-ups

Key differences:

• Want instant results
• Have a special event coming up
• Prefer minimal effort or follow-up

• Want gradual results over time
• Are managing sensitivity
• Need a more cost-effective solution
• Want to maintain previous whitening results

1. Can I start with a take-home kit and switch to in-chair whitening later? Yes, many patients begin with at-home whitening and then opt for in-chair treatments for touch-ups or quicker results.
2. Will whitening work on dental restorations like veneers or crowns? No, whitening only affects natural teeth. Speak to your dentist if you have visible restorations that may need colour matching.
3. How often can I whiten my teeth? Most patients can whiten once or twice a year. Over-whitening can cause enamel damage or sensitivity, so always follow your dentist’s advice.
4. Are in-chair treatments safe for people with sensitive teeth? Yes, especially when desensitising agents are used. Your dentist can adjust the gel strength and duration based on your needs.
