Why has my composite bonding turned yellow?

If you’ve had dental bonding work chances are you’ve loved the improvement to your smile but may be slightly concerned about composite bonding discolouration or yellowing that can occur over time. If your previous dentist failed to make you aware of factors that can cause resin bonding staining, Venneir is here to clear everything up. In our latest blog post, we cover everything you need to know about dental bonding, the causes of discolouration and how to avoid it to keep your composite bonding looking white and as good as new!

What is dental bonding?

Dental bonding, or composite bonding, is a cosmetic procedure that uses tooth-coloured resin to improve or enhance your smile. This may be through filling in chips, and gaps or reshaping certain teeth. Resin bonding can do wonders to alter the overall appearance of your teeth and lasts on average around 5 years before new dental work is needed. If the bonding is looked after properly, teeth can remain looking as good as new. However, there are certain factors that cause composite bonding to yellow and discolour. 

What causes resin bonding to yellow?

There are a number of reasons why dental bonding can lose its original white colour. Firstly you may be using a toothpaste that is too abrasive. Over time this can break down the resin that makes up your composite bonding and increase the risk of yellowing or staining. Drinking certain liquids also puts you at further risk of damage to your resin bonding, for example, coffee or red wines. A lack of attention to everyday dental hygiene also means you’re more likely to experience composite bonding discolouration.

Tips for avoiding composite bonding discolouration

Dental bonding is a big investment and you want to ensure that the procedure not only lasts as long as possible but also stays looking great as well. Read on below for our top tips for avoiding the yellowing of your composite bonding over time: 

1. Limit your drinking of staining beverages: In order to keep your composite bonding a pearly white colour for as long as possible, you might want to limit your drinking of coffee, red wine and other liquids and food that are likely to cause staining. If you find this too hard, at least take the additional step of drinking through a straw to limit liquid contact with your resin bonding.
2. Use a dentist-approved toothpaste: As previously mentioned, using toothpaste that is too harsh and abrasive can contribute to a premature breakdown of the composite resin, meaning yellowing is far more likely. Make sure to use a dentist-approved toothpaste that has been designed specifically to care for dental bonding smiles. 
3. Maintain daily dental hygiene: One of the best ways you can care for your composite bonding and prevent staining is to keep up dedicated daily dental hygiene routines. This means brushing twice daily, flossing and looking after your gums. Regular care helps to ensure your teeth are free from food and plaque which can cause staining over time.
