Everything You Should Know Before You Start Teeth whitening

Teeth whitening improves the brightness of your smile by removing stains from your enamel. People choose whitening when they want a cleaner, fresher look without complex dental treatment. You get fast results, simple aftercare, and a clear improvement in confidence

Your teeth whitening dentist at Thousand Smiles in London checks your enamel before whitening. You receive a plan that fits your sensitivity level and your goals

What whitening actually does

Whitening changes the shade of the tooth by targeting stain molecules. Drinks, food, and lifestyle habits leave colour inside enamel pores. Whitening gel breaks these stains down and lifts them. The process brightens your smile without damaging the tooth surface

Stains come from

• tea
• coffee
• red wine
• smoking
• fizzy drinks
• age related darkening

Whitening works best when supervised by a dentist to ensure an even result

Whitening options you can choose

There are two dental options. Both safely lighten tooth colour when used correctly

In clinic whitening

You receive gel application by your dentist and a light activation step. This gives fast improvement in a single appointment

Home whitening

You receive custom trays and whitening gel. You use them at home for several days. This gives gradual, controlled results

Both options work well. Your dentist advises which suits your enamel

Who whitening helps

Whitening improves your smile when you

• feel unhappy with yellowing
• want a fresher look
• prepare for a wedding or event
• want a simple confidence boost
• dislike stains from drinks
• want a clean base for bonding or veneers

People in London often choose whitening before cosmetic work to match new bonding or veneers accurately

When whitening does not work

Whitening does not change the colour of

• veneers
• crowns
• fillings
• internal stains from trauma

Our dentist helps you choose bonding or veneers if whitening cannot fix deeper problems

How white you can go

Each person has a natural shade limit. Your enamel responds differently based on thickness, stain depth, and age. Your dentist measures your starting shade and shows your likely result. Most people achieve a noticeably brighter smile with a natural look

Sensitivity during treatment

Mild sensitivity is common. It reduces once enamel settles. Your dentist gives solutions such as

• fluoride toothpaste
• shorter wear times
• lower gel strength
• desensitising gel

These steps keep you comfortable

How long results last

Whitening lasts several months. Your habits shape how long your shade stays bright. You protect the result by reducing staining drinks and following daily hygiene

Your shade lasts longer when you

• rinse after tea or coffee
• use a straw for dark drinks
• brush twice daily
• attend hygiene visits
• use home top ups when needed

These habits keep your smile bright for longer

Whitening and hygiene

Clean enamel responds better to whitening. You book a hygiene appointment before starting. This removes plaque and tartar which might block the whitening gel. You get an even, consistent shade because whitening reaches every surface

What to expect during treatment

Whitening is straightforward

• your dentist checks your enamel
• you record your starting shade
• you receive in clinic or home whitening
• you track your progress
• you complete the sessions
• your dentist checks your final shade

This process stays simple and comfortable

Why dentist supervised whitening is safest

Dentist supervised whitening protects your enamel and gums. Your dentist controls gel concentration and protects soft tissue. Over the counter kits often cause uneven results or increased sensitivity. Professional whitening gives predictable improvement and long term safety

Long term care

You keep your whitening result stable by

• rinsing after coloured foods
• brushing twice daily
• drinking more water
• limiting smoking
• using top ups when needed
• attending regular dental visits

These habits protect your investment and improve oral health
