Why Teeth Lose Their Brightness
Tooth discolouration happens gradually over time due to a combination of extrinsic (surface) and intrinsic (internal) staining. Common culprits include coffee, tea, red wine, tobacco, certain medications, and the natural ageing process.
As we age, the outer enamel layer thins, revealing more of the yellowish dentin layer beneath. This is why even people with excellent oral hygiene notice their teeth becoming less brilliant over time.
The average person's teeth darken by 2-3 shades every decade due to natural ageing alone, even with consistent oral hygiene.
Professional vs Over-the-Counter Options
While drugstore whitening products can provide modest improvement, professional in-office whitening delivers dramatically superior results in a fraction of the time.
Professional treatments use higher concentrations of whitening agents (hydrogen peroxide or carbamide peroxide) applied under controlled conditions, ensuring safety and maximum effectiveness. Your dentist can also customise the treatment to address specific areas and manage sensitivity.
- Professional: Up to 8 shades brighter in one session
- OTC strips: 1-2 shades over several weeks
- Professional treatments are supervised for safety
- Custom trays ensure even coverage without gum irritation
- Results are more predictable and longer-lasting
The In-Office Whitening Process
A professional whitening session at Dental Wellness typically takes 60-90 minutes and follows a precise protocol:
First, your dentist will document your current shade and protect your gums with a barrier gel. Next, a professional-grade whitening gel is applied to your teeth in multiple cycles, sometimes activated by a special light.
You'll see visible results immediately after the session. Many patients are amazed at the transformation they see in the mirror after just one appointment.
Maintaining Your Results
To keep your newly brightened smile looking its best, we recommend following the '48-hour rule' — avoid dark-coloured foods and beverages for the first two days after treatment when teeth are most susceptible to re-staining.
Long-term maintenance includes using a whitening toothpaste, rinsing after consuming staining beverages, and scheduling periodic touch-up treatments every 6-12 months.
- Avoid coffee, red wine, and berries for 48 hours post-treatment
- Use a straw for dark beverages when possible
- Brush or rinse after consuming staining foods
- Touch-up treatments extend results significantly
- Custom take-home trays provided for maintenance
Safety & Managing Sensitivity
Professional teeth whitening is a safe procedure when performed by a qualified dentist. Some patients experience temporary tooth sensitivity during or after treatment, which typically resolves within 24-48 hours.
Your dentist may recommend desensitizing toothpaste before and after the procedure, and will adjust the whitening concentration based on your individual sensitivity level. People with existing dental restorations (crowns, veneers) should know that whitening only affects natural tooth structure.
