What is dental bonding?

Composite bonding is where a dentist attaches tooth coloured composite resin to one or more of your natural teeth and then shapes it to restore the natural look of each tooth. It is used on cracked or chipped teeth, or to fill gaps between the teeth. You can use composite bonding to not only cover up damage to the teeth but also to change the overall shape and colour of your teeth.

This method of tooth restoration is mostly used to make minor cosmetic corrections to your smile. It's also a cheaper option than veneers or crowns, and much less invasive. Veneers and crowns usually require that some of your enamel be removed to make room, which is an irreversible process.

Why would someone need to get teeth bonding?

There are a few issues that bonding can help with aesthetically, including:

  • Diastema (gaps between teeth)
  • Cracked or chipped teeth
  • Discoloured teeth
  • Teeth that are crooked or misshapen

Teeth bonding is meant to even out the size, shape, or colour of teeth, or cover any minor cosmetic issues in someone's smile. Generally, nobody can tell if you've had your teeth bonded — besides a dentist! Composite bonding is often used for fillings and veneers.

How does bonding respond to colour?

Bonding resin can be stained on the surface, but if you attempt to brighten the overall colour with whitening products it will not become change colour and appear whiter. This is because natural teeth are porous and composite bonding is nonporous.

Stains form on your natural teeth when the staining agents penetrate your teeth's pores. Similarly, whitening agents penetrate the surface of your teeth to whiten them.

Due to the nonporous nature of resin, whitening agents can't penetrate them. So, your bonded teeth can look stained and discoloured in certain areas due to the contrast with your natural teeth. 

Composite bonding is made from a solution of inorganic filler particles, such as quartz or glass bound together in a plastic matrix. This type of material will absorb stains, which will then become part of the bonding structure.  

For example, if you drink a lot of highly pigmented beverages, like coffee or tea, they will penetrate the plastic and stain permanently.

If you’re looking to maintain a bright smile, it’s essential to understand that the resin material used for dental bonding will stain over time. However, even though composite resin stains it doesn’t respond to whitening treatments.

According to the National Center for Biotechnology Information, whitening agents will only reduce the strength of teeth bonding. Therefore, whitening treatments will cause your natural teeth becoming a different shade than the bonding material. Luckily, there are certain things you can do to maintain those pearly whites! 

When should I whiten my bonded teeth?

The best time to whiten your natural teeth is before you have a bonding procedure. That way, your teeth are at their whitest when your dental professional colour-matches the bonding resin. Then, if you keep your teeth white with good oral care and touch-up treatments, your natural and bonded teeth will continue to match.

Some of the whitening treatments you can try before you get your teeth bonded to include:

You can also try some natural whitening methods like lemon peel whitening, but they won't be as effective.
