What Is a Composite Build-Up?

If your dentist has recommended a composite build-up, you might be wondering exactly what that involves. This article explains what a composite build-up is, when it’s typically recommended, what to expect during the procedure, and how to care for your teeth afterwards.

What Is a Composite Build-Up?

A composite build-up is a restorative dental procedure in which tooth-coloured resin material is used to rebuild a tooth that has been damaged, decayed, or significantly worn down. The aim is to restore the tooth’s natural shape, function, and strength.
The resin material is colour-matched to your natural teeth, so the restoration blends in with the rest of your smile. In most cases, the procedure can be completed in a single visit to Langmore Dental.

When Might a Composite Build-Up Be Recommended?

Our AHPRA-registered dentists may recommend a composite build-up in a number of situations, including:
• When a tooth has significant decay or damage that affects its structure
• When a large, old filling needs to be replaced
• When a tooth is too broken down to support a new filling on its own
• When preparing a tooth to receive a dental crown
Whether a composite build-up is the right approach for your tooth depends on your individual situation. Your dentist will assess the tooth and explain the recommended treatment, including any alternatives, during your consultation.

What to Expect During the Procedure

A composite build-up generally involves the following steps:
1. Examination — your dentist examines the tooth and confirms the treatment plan with you, answering any questions before starting
2. Preparation — the affected area is cleaned, and any decay is removed; a bonding agent is applied to help the resin adhere
3. Application — the tooth-coloured resin is applied in layers and shaped to rebuild the tooth’s natural form, with each layer set using a curing light
4. Finishing — the build-up is polished, and your bite is checked to ensure it feels comfortable and functions correctly

What to Consider?

As with any dental restoration, there are a few things to keep in mind:
• Individual results vary depending on the extent of the original damage, your oral health, and how well the restoration is cared for
• Some patients experience mild sensitivity in the days following treatment, which generally settles
• Composite build-ups require the same care as natural teeth — regular brushing, flossing, and check-ups help them last longer
• Your dentist will discuss what to expect for your specific situation, including realistic expectations around durability and maintenance

Caring for Your Composite Build-Up

Looking after a composite build-up doesn’t require any special routine — good general oral hygiene is the key:
• Brush twice daily with a non-abrasive fluoride toothpaste
• Floss daily to keep the margins of the restoration clean
• Attend regular check-ups so your dentist can monitor the restoration over time
• Avoid using your teeth to open packaging or bite very hard foods or objects
• If you grind your teeth, speak to your dentist — a night guard may help protect the restoration
