Cosmetic and orthodontic guide
5 min readComposite bonding
Composite bonding can change tooth shape or appearance in selected cases. It can chip, stain and need maintenance or replacement.
Composite bonding uses tooth-coloured resin to add to or reshape teeth in selected cases. It may be minimally invasive, but that does not mean it is reversible for every person.
Suitability depends on tooth position, bite, enamel, habits, existing restorations and expectations. A dentist should discuss limitations and alternatives.

What composite bonding involves
A dentist places and shapes tooth-coloured composite resin on the tooth. Some cases need little tooth preparation, while others need more planning or alternative treatment.
Possible causes or contributing factors
- Small chips, spaces, uneven edges or shape concerns.
- Staining or wear where composite may be considered.
- Bite, grinding or habits that can affect durability.
What you can do now
- Ask whether bonding is suitable for your bite and enamel.
- Discuss staining, chipping, maintenance and replacement.
- Ask about alternatives such as smoothing, orthodontics, whitening or veneers.
What not to do
- Do not assume bonding is reversible in every case.
- Do not use bonding to hide untreated decay or gum disease.
- Do not bite hard objects with bonded edges.
When to contact a dentist
- You are considering bonding for shape or appearance.
- Bonding chips, stains, feels rough or affects the bite.
