Is Professional Teeth Whitening Worth It? Pros and Cons Explained
As one of Cardiff’s most requested cosmetic dental treatments, professional teeth whitening can transform your smile dramatically. But with teeth whitening in Cardiff prices ranging from £200 to £600, many patients wonder if it’s worth the investment compared to drugstore alternatives. This comprehensive guide examines all factors you should consider before booking your whitening treatment.
What Is Professional Teeth Whitening?
Professional teeth whitening refers to bleaching treatments performed by qualified dentists using higher-concentration peroxide gels than available in over-the-counter products. There are two main types:
In-Office Whitening
Completed in about 60-90 minutes at your Cardiff dental practice, this treatment uses concentrated hydrogen peroxide (15-43%) activated by special lights or lasers for immediate results.
Take-Home Professional Kits
Custom-fitted trays with carbamide peroxide gel (10-20%) worn for several hours daily over 1-2 weeks. Less expensive than in-office but takes longer for full results.
Benefits of Professional Whitening
- Dramatic results: 5-10 shades lighter in one session
- Customized treatment: Dentists adjust strength for your sensitivity levels
- Safe application: Gums protected from bleach irritation
- Longer-lasting: Results persist 1-3 years with proper care
- Immediate: See change right after in-office treatment
- Addresss intrinsic stains: Works on deep discoloration that surface whiteners can’t touch
Drawbacks to Consider
- Higher cost: £200-600 vs. £10-50 for store products
- Temporary sensitivity: 24-48 hours of increased tooth sensitivity is common
- Not permanent: Requires maintenance treatments
- Doesn’t work on all teeth: Crowns, veneers and some stains won’t whiten
- Time commitment: Multiple appointments may be needed
- Possible gum irritation: If not applied properly

Who Should Avoid Teeth Whitening?
Professional whitening isn’t recommended for:
- Pregnant or breastfeeding women
- People with untreated cavities or gum disease
- Those with extremely sensitive teeth
- Patients with many dental restorations (crowns/veneers won’t whiten)
- Children under 16 (developing teeth may be damaged)
Always consult with a qualified Cardiff dentist before beginning any whitening treatment.
What to Expect During Professional Whitening
Before Treatment
Your dentist will:
- Examine your teeth and gums for any issues
- Take “before” photos to track progress
- Match your current shade to a dental color chart
- Clean teeth to remove surface stains
- Discuss realistic expectations based on your tooth type and stains
During the Procedure
A typical in-office session includes:
- Application of protective gel or rubber shield for gums
- Layering of whitening gel on tooth surfaces
- Activation with special light (for some systems)
- Reapplication of gel every 15-20 minutes (2-4 times)
- Final rinse and fluoride treatment
“I was amazed at the difference after just one session of professional whitening. My coffee stains disappeared completely, and I gained about 7 shades whiter teeth. The sensitivity lasted about a day but was well worth it for the confidence boost.”
Maintaining Your Whitened Smile
To prolong your results:
- Avoid stain-causing foods/drinks for 48 hours after treatment
- Use a straw for coffee, tea, and dark sodas
- Rinse with water after consuming staining substances
- Brush with whitening toothpaste 1-2 times weekly
- Schedule touch-up treatments every 6-18 months
- Consider professional hygiene cleanings every 6 months
Professional Teeth Whitening FAQs
Most patients achieve 5-10 shades lighter, but results depend on your natural tooth color and type of staining. Yellow teeth typically whiten better than grayish teeth. Your dentist can give you a realistic expectation during consultation.
When performed by a qualified dentist, professional whitening is safe for enamel. The process temporarily opens microscopic pores in enamel to remove stains, then the pores close naturally. Overuse of home products poses greater enamel risks than properly administered professional treatments.
Whitening only affects natural tooth structure. Crowns, veneers, fillings and bonding won’t change color. You may need to replace these to match your newly whitened teeth, which can add to the overall cost.
Most sensitivity resolves within 24-48 hours. Your dentist may recommend desensitizing toothpaste or fluoride treatments. People with existing sensitivity may experience longer discomfort.
For severe discoloration that doesn’t respond to bleaching, consider porcelain veneers or composite bonding. These options mask rather than remove stains.
