In cosmetic dentistry, composite bonding is frequently used to repair defects, seal gaps, and improve teeth's appearance by altering their colour and shape. Because the resin is the same colour as real enamel, patients frequently enquire as to whether it can be whitened in the future, like natural teeth.

Can you whiten composite bonding?

Simply no, traditional bleaching treatments don't make composite bonding whiter. Over-the-counter and professional whitening gels are made to make natural enamel lighter. Composite resin is not porous, so its colour doesn't change when it comes in contact with whitening agents.

This procedure means that if you whiten your real teeth, the areas that are bonded may look darker in comparison.

Why composite bonding changes colour as time goes on?

Bonding can get stained. The resin surface may take in pigments from:

Tea and coffee
Red wine
Using tobacco
Curry and deeply pigmented foods
Poor oral hygiene

Stains on the surface can make bonding look dull or yellow.

How to make composite bonding look better?

Professional Polishing

A dentist can polish the bonding material to get rid of stains on the surface and bring back its original shine. This is usually the first and easiest thing to do.

Fixing or resurfacing composite

If the discolouration is deeper, the dentist may lightly resurface the tooth or add a thin new layer of composite to make it look better.

Replacement

When bonding is very stained or worn, the best way to make it look good is to replace it.

Should you whiten your teeth before getting bonding?

Yes, it's best to whiten your teeth before getting composite bonding if you're thinking about it. This lets your dentist match the bonding to the colour of your whiter teeth so that your smile looks even.

How to keep composite bonding from staining

To keep the colour of your bonding:

Brush twice daily with a non-abrasive toothpaste.
Floss every day to keep plaque from building up.
Limit drinks that stain or rinse your mouth with water after drinking.
Avoid smoking
Every six months, have a professional cleaning.

How long does the colour of composite bonding last?

If you take care of it, composite bonding can look good for 5 to 7 years. Regular dental visits and good oral hygiene can make it last a lot longer.

When to go to the dentist

A dental exam can tell you if polishing, fixing, or replacing your bonding is the best option if it looks darker than your natural teeth or has lost its shine.

Can you whiten composite bonding at home?

Composite bonding cannot be whitened at home because whitening products only affect natural enamel. However, good oral hygiene, stain-reducing toothpaste, and limiting coffee, tea, and smoking can help prevent discolouration and maintain its appearance.
