Composite restoration: a quick and easy guide

Posted on Feb 17, 2021 in News

Do you need to restore structure to your teeth? Dr Colomar, one of the members of Moira Wong Orthodontics, is an expert on composite restoration who regularly performs the procedure. In this article, she shares her professional expertise to give you a quick and simple guide to composite restoration.

What is a composite restoration?

composite restoration is made up of acrylic, which is white/tooth coloured. Many people call a composite restoration a “filling”. However, a key difference is that a composite restoration can only be performed with white acrylic while a “filling” refers to restoring the teeth with any dental material.

When is composite restoration needed?

Composite restoration is used to restore tooth structure that is missing from teeth. Missing tooth structure can be caused by caries (tooth decay), dental trauma, enamel defects (some people are born with anomalies on tooth structure) tooth wear (from erosion, attrition or abrasion) or for aesthetic purposes.

Are composite restorations noticeable?

No, composite restorations are not noticeable if done properly with the correct shape and shade. Some dentists may fill the hole in a tooth and not take into account the shape of the teeth. However, if you follow the tooth shape anatomy and you choose the right shade (as we do at Moira Wong Orthodontics), giving good aesthetics to the tooth, the restoration will not be noticeable.

How does a dentist perform composite restoration?

Firstly, the tooth is isolated. Then, the surface being restored is etched and prepared with tooth adhesive. The composite material is layered in small increments and moulded to the required shape. After, the composite resin is polymerised with ultraviolet light to set and finally, the restoration is adjusted and polished.

What is the success rate of composite restoration?

Composite restoration has a good success rate with an annual failure rate that varies from 1 to 5 per cent. The major causes for failure in posterior teeth are caries (tooth decay) and fracture. With anterior teeth, aesthetic concerns are the main reasons leading to restoration failures. The failure rate is very low.

Can composite restorations be replaced multiple times?

Composite restorations can be replaced but ideally the less the better. Every time they are removed, the tooth suffers from the mechanical vibration and they are difficult to remove without damaging the peripheral healthy enamel and dentine (the hard tissue under the enamel that forms the majority of the tooth).

What should be avoided after having the composite restoration?

After the procedure, you can eat or drink straight away and there is no need for special precautions. After composite restoration, the recommendations for what to avoid are the same as general advice regarding teeth care, like to avoid biting nails or chewing items such as pen lids, which may chip the composite restoration.

Dr. Moira Wong – Orthodontist

An exceptionally skilled orthodontist who simply loves to improve the smiles of adults and children.

Dr Moira Wong (GDC no: 67960, UK) developed an ambition to specialise in the field of orthodontics during her time as a dentistry student at the London Hospital Medical College. After graduating in 1994, she gained experience in all fields of dentistry prior to specialisation. This included working as part of the Pennstar trauma team at the University of Pennsylvania.

Dr Wong’s career pathway began with a spell as a house officer in prosthetic dentistry at the Royal London Hospital, followed by senior house officer positions at the Bristol Dental Hospital. During this period she gained her fellowship in dental surgery and worked in the paediatric dentistry department, treating special needs children and addressing complicated developmental problems. She also worked with adults requiring the replacement of multiple teeth.

Returning to London to take up a position as a senior house officer in oral surgery, Dr Wong gained experience in dental and facial surgery. One of her busiest nights was helping with the suturing of patients following a national rail crash.

Dr Wong was then accepted onto the specialty training programme at Guy’s Hospital, where she spent a further three years gaining her master’s degree. She continued onto a consultant training programme at King’s College and St George’s Hospital, gaining her Fellowship in orthodontics. Currently less than 300 UK practitioners have this level of training, with just 5 to 10 people gaining the accreditation in an average year.

Today, Dr Wong has acquired an excellent reputation for her highly sophisticated work and approachable, communicative manner. Her ambition is to be recognised as nothing less than the best orthodontist in London.
